Berger Emergency Management Coordinator RE: Dubuque County Multi-Jurisdictional Hazard Mitigation Plan Approval INTRODUCTION This memorandum accompanies a letter from the Federal Emergency Management Agency about the recently approved Dubuque County Multi-Jurisdictional Hazard Mitigation Plan. BACKGROUND In March of 2016, the Dubuque County Emergency Management Commission submitted a Hazard Mitigation Grant Application to the State of lowa to update the current Dubuque County MJHMP. On March 10, 2017 the application was approved and Dubuque County was included in a multi-county contract awarded by lowa Homeland Security and Emergency Management Division (HSEMD) to Amec Foster Wheeler to coordinate the updating, completion and submission of the plan. The planning process consisted of multiple meetings with the contractor and involved many email exchanges of information to update the plan. Each school district, city and the county formed committees, participating and updating their portion of the plan. In July of 2018 the draft plan was distributed for public comment and review. No public comments were received. In August 2018 the plan was submitted to the State of lowa and then to FEMA for approval. We received a request for some additional information and clarification from FEMA in December of 2018. Amec Foster Wheeler and I submitted some additional information at the request of FEMA reviewers, deleted some response activities not applicable to hazard mitigation and provided the additional information as requested. On February 28�h, 2019 we received FEMA approval. Review of the plan will be annually and the plan is active for five years after adoption of the plan by resolution. CONCLUSION & RECOMMENDATION This memorandum is to notify you of the successful completion of the plan and ultimately the approval from FEMA that it meets all of the current standards for hazard mitigation plan. The City of Dubuque will need to approve the plan by resolution at a future council meeting.

Mitigation Plan 2018 EXECUTIVE SUMMARY The purpose of hazard mitigation is to reduce or eliminate long-term risk to people and property from hazards. Dubuque County and participating jurisdictions developed this multi-jurisdictional local hazard mitigation plan update to reduce future losses to the County and its communities as a result of hazard events. The plan was prepared pursuant to the requirements of the Disaster Mitigation Act of 2000 and to achieve eligibility for the Federal Emergency Management Agency (FEMA) Hazard Mitigation Assistance Grant Programs. The Dubuque County Multi-jurisdictional Hazard Mitigation Plan covers the following jurisdictions that participated in the planning process: • Unincorporated County • Asbury • Balltown • Bankston • Bernard • Cascade • Centralia • Dubuque • Durango • Dyersville • Epworth • Farley • Graf • Holy Cross • Luxemburg • New Vienna • Peosta • Rickardsville • Sageville • Sherrill • Worthington • Zwingle • Dubuque Public School District • Western Dubuque Public School District Dubuque County, the incorporated areas, and public school districts listed above developed a Multi-jurisdictional Hazard Mitigation Plan that was approved by FEMA on May 7, 2013 (hereafter referred to as the 2013 Dubuque County Hazard Mitigation Plan). Therefore, this current planning effort serves to update the previous plan. Dubuque County, lowa v Multi-jurisdictional Hazard Mitigation Plan 2018 The plan update process followed a methodology prescribed by FEMA, which began with the formation of a Hazard Mitigation Planning Committee (HMPC) comprised of representatives from Dubuque County, participating jurisdictions, and stakeholders. The HMPC updated the risk assessment that identified and profiled hazards that pose a risk to the Dubuque County planning area, assessed the vulnerability to these hazards, and examined the capabilities in place to mitigate them. The planning area is vulnerable to several hazards that are identified, profiled, and analyzed in this plan. Based upon the risk assessment, the HMPC reviewed the previously developed goals for reducing risk from hazards. The updated goals are listed below: • Goal 1: Increase capabilities within Dubuque County entities to mitigate the effects of hazards by enhancing existing or designing and adopting new policies that will reduce damaging effects of hazards. • Goal 2: Protect the most vulnerable populations, buildings and critical facilities within Dubuque County through the implementation of cost effective and technically feasible mitigation projects. • Goal 3: Improve the level of responder, government, business and citizen awareness and preparedness for disasters. • Goal 4: Develop programs to assure that response agencies, governments, educational institutions and local businesses are able to operate during times of disaster. To meet the identified goals, the recommended mitigation action details are in Chapter 4. The HMPC developed an implementation plan for each action, which identifies priority level, background information, responsible agency, timeline, cost estimate, potential funding sources, and more. Dubuque County, lowa vi Multi-jurisdictional Hazard Mitigation Plan 2018 PREREQUISITES 44 CFR requirement 201.6(c)(5): The local hazard mitigation plan shall include documentation that the plan has been formally adopted by the governing body of the jurisdiction requesting approval of the plan. For multi-jurisdictional plans, each jurisdiction requesting approval of the plan must document that it has been formally adopted. Note to Reviewers: When this plan has been reviewed and approved pending adoption by FEMA Region Vll the adoption resolutions will be signed by the participating jurisdictions and added to Appendix D. A model resolution is provided. The following jurisdictions participated in the development of this plan and have adopted the multi-jurisdictional plan. Resolutions of Adoptions are included in Appendix D. • Unincorporated County • Asbury • Balltown • Bankston • Bernard • Cascade • Centralia • Dubuque • Durango • Dyersville • Epworth • Farley • Graf • Holy Cross • Luxemburg • New Vienna • Peosta • Rickardsville • Sageville • Sherrill • Worthington • Zwingle • Dubuque Public School District • Western Dubuque Public School District Dubuque County, lowa vii Multi-jurisdictional Hazard Mitigation Plan 2018 Model Resolution Resolution # Adopting the Dubuque County Multi-Jurisdictional Local Hazard Mitigation Plan Whereas, the (Name of Government/DistricUOrganization seeking FEMA approval of hazard mitigation plan) recognizes the threat that natural hazards pose to people and property within our community; and Whereas, undertaking hazard mitigation actions will reduce the potential for harm to people and property from future hazard occurrences; and Whereas, the U.S Congress passed the Disaster Mitigation Act of 2000 ("Disaster Mitigation AcY') emphasizing the need for pre-disaster mitigation of potential hazards; Whereas, the Disaster Mitigation Act made available hazard mitigation grants to state and local governments; and Whereas, an adopted Local Hazard Mitigation Plan is required as a condition of future funding for mitigation projects under multiple FEMA pre- and post-disaster mitigation grant programs; and Whereas, the (Name of Government/DistricUOrganization) fully participated in the hazard mitigation planning process to prepare this Multi-Jurisdictional Local Hazard Mitigation Plan; and Whereas, the lowa Homeland Security and Emergency Management Department and the Federal Emergency Management Agency Region VII officials have reviewed the "Dubuque County Multi-Jurisdictional Local Hazard Mitigation Plan," and approved it contingent upon this official adoption of the participating governing body; and Whereas, the (Name of Government/DistricUOrganization) desires to comply with the requirements of the Disaster Mitigation Act and to augment its emergency planning efforts by formally adopting the Dubuque County Multi-Jurisdictional Local Hazard Mitigation Plan; and Whereas, adoption by the governing body for the (Name of Government/District/Organization) demonstrates the jurisdictions' commitment to fulfilling the mitigation goals outlined in this Multi- Jurisdictional Local Hazard Mitigation Plan Whereas, adoption of this legitimizes the plan and authorizes responsible agencies to carry out their responsibilities under the plan; Now, therefore, be it resolved, that the (Name of Government/DistricUOrganization) adopts the "Dubuque County Multi-Jurisdictional Local Hazard Mitigation Plan" as an official plan; and Be it further resolved, the (Name of Government/DistricUOrganization) will submit this Adoption Resolution to the lowa Homeland Security and Emergency Management Department and Federal Emergency Management Agency Region VII officials to enable the plan's final approval.

This plan demonstrates the jurisdictions' commitments to reducing risks from hazards and serves as a tool to help decision makers direct mitigation activities and resources. This plan was also developed to make Dubuque County and the participating jurisdictions eligible for certain federal grant programs, specifically the Federal Emergency Management Agency's (FEMA) Hazard Mitigation Assistance (HMA) grants including the Hazard Mitigation Grant Program, Pre-Disaster Mitigation Program, and Flood Mitigation Assistance Program. 1 .2 Background and Scope Each year in the United States, disasters take the lives of hundreds of people and injure thousands more. Nationwide, taxpayers pay billions of dollars annually to help communities, organizations, businesses, and individuals recover from disasters. These monies only partially reflect the true cost of disasters, because additional expenses to insurance companies and nongovernmental organizations are not reimbursed by tax dollars. Many disasters are predictable, and much of the damage caused by these events can be alleviated or even eliminated. Hazard mitigation is defined by FEMA as "any sustained action taken to reduce or eliminate long-term risk to human life and property from a hazard event." The results of a three-year, congressionally mandated independent study to assess future savings from mitigation activities provides evidence that mitigation activities are highly cost-effective. On average, each dollar spent on mitigation saves society $4 in avoided future losses, in addition to saving lives and preventing injuries (National Institute of Building Science Multi-Hazard Mitigation Council 2005). Hazard mitigation planning is the process through which hazards that threaten communities are identified, likely impacts of those hazards are determined, mitigation goals are set, and appropriate strategies to lessen impacts are determined, prioritized, and implemented. Dubuque Dubuque County, lowa 1.1 Multi-jurisdictional Hazard Mitigation Plan 2018 County and the participating incorporated cities and public school districts that participated in this plan update developed a Multi-Jurisdictional Hazard Mitigation Plan that was approved by FEMA on May 7, 2013 (hereafter referred to as the 2013 Dubuque CountyHazard Mitigation Plan). Therefore, this current planning effort serves to update the previous plan. This plan documents the hazard mitigation planning process undertaken by the Dubuque County Hazard Mitigation Planning Committee (HMPC). It identifies relevant hazards and vulnerabilities in the planning area and sets forth an updated mitigation strategy to decrease vulnerability and increase resiliency and sustainability in Dubuque County. The Dubuque County Multi-Jurisdictional Hazard Mitigation Plan is a multi-jurisdictional plan that geographically covers the participating jurisdictions within Dubuque County's boundaries (hereinafter referred to as the planning area). The following jurisdictions officially participated in the planning process: • Unincorporated Dubuque County • City of Asbury • City of Balltwon • City of Bankston • City of Bernard • City of Cascade • City of Centralia • City of Dubuque • City of Durango • City of Dyersville • City of Epworth • City of Farley • City of Graf • City of Holy Cross • City of Luxemburg • City of New Vienna • City of Peosta • City of Rickardsville • City of Sageville • City of Sherrill • City of Worthington • City of Zwingle • Dubuque Public Schools • Western Dubuque Public Schools This plan was prepared pursuant to the requirements of the Disaster Mitigation Act of 2000 (Public Law 106-390) and the implementing regulations set forth by the Interim Final Rule published in the Federal Register on February 26, 2002, (44 CFR §201.6) and finalized on October 31, 2007. (Hereafter, these requirements and regulations will be referred to collectively Dubuque County, lowa 12 Multi-jurisdictional Hazard Mitigation Plan 2018 as the Disaster Mitigation Act.) Additionally, this plan is prepared in accordance with the 2013 Local Mitigation Planning Handbook published by FEMA. While the Disaster Mitigation Act emphasized the need for mitigation plans and more coordinated mitigation planning and implementation efforts, the regulations established the requirements that local hazard mitigation plans must meet in order for a local jurisdiction to be eligible for certain federal disaster assistance and hazard mitigation funding under the Robert T. Stafford Disaster Relief and Emergency Act (Public Law 93-288). Information in this plan will be used to help guide and coordinate mitigation activities and decisions for local land use policy in the future. Proactive mitigation planning will help reduce the cost of disaster response and recovery to communities and their residents by protecting critical community facilities, reducing liability exposure, and minimizing overall community impacts and disruptions. The Dubuque County planning area has been affected by hazards in the past and the participating jurisdictions are therefore committed to reducing future impacts from hazard events and becoming eligible for mitigation-related federal funding. Dubuque County, lowa 1.3 Multi-jurisdictional Hazard Mitigation Plan 2018 1 .3 Plan Organization This Dubuque County Multi-jurisdictional Hazard Mitigation Plan update is organized as follows: • Executive Summary • Chapter 1: Introduction and Planning Process • Chapter 2: Planning Area Profile and Capabilities • Chapter 3: Risk Assessment • Chapter 4: Mitigation Strategy • Chapter 5: Plan Implementation and Maintenance • Appendices This is the same general format that was used for the 2013 Dubuque County Hazard Mitigation Plan except that in the previous plan, the Risk Assessment Chapter presented the Hazard Profiles of each hazard in one section and then Vulnerability Assessment for each hazard in a separate section. In this plan, the Hazard Profile and Vulnerability Assessment for each hazard is presented in the same section. 1 .4 Planning Process 44 CFR Requirement 201.6(c)(1): [The plan shall document] the planning process used to develop the plan, including how it was prepared, who was involved in the process, and how the public was involved. In February 2017, the State of lowa Homeland Security and Emergency Management Department contracted with Amec Foster Wheeler, Environment & Infrastructure, Inc. to facilitate the update of the Dubuque County Multi-jurisdictional Local Hazard Mitigation Plan. Amec Foster Wheeler's role was to: • Assist in establishing the Hazard Mitigation Planning Committee (HMPC) as defined by the Disaster Mitigation Act (DMA), • Ensure the updated plan meets the DMA requirements as established by federal regulations and following FEMA's planning guidance, • Facilitate the entire planning process, • Identify the data requirements that HMPC participants could provide and conduct the research and documentation necessary to augment that data, • Assist in facilitating the public input process, • Produce the draft and final plan update documents, and • Coordinate the lowa Homeland Security and Emergency Management Department and FEMA plan reviews. Dubuque County, lowa 1.4 Multi-jurisdictional Hazard Mitigation Plan 2018 1 .4.1 Multi-Jurisdictional Participation 44 CFR Requirement §201.6(a)(3): Multi-jurisdictional plans may be accepted, as appropriate, as long as each jurisdiction has participated in the process and has officially adopted the plan. Dubuque County invited the incorporated cities, public school districts, and various other stakeholders in mitigation planning (identified in Appendix B) to participate in the Dubuque County Multi-jurisdictional Hazard Mitigation Plan update process. The jurisdictions that elected to participate in this plan are listed above in section 1.2. The DMA requires that each jurisdiction that participates in the planning process must officially adopt the multi-jurisdictional hazard mitigation plan. Each jurisdiction that chose to participate in the planning process and development of the plan was required to meet plan participation requirements defined at the first planning meeting, which includes the following: • Designate a representative to serve on the HMPC; • Participate in at least one of the three HMPC planning meetings by either direct representation or authorized representation; • Provide data for and assist in the development of the updated risk assessment that describes howvarious hazards impacttheirjurisdiction; • Provide data to describe current capabilities; • Develop/update mitigation actions (at least one) specific to each jurisdiction; • Provide comments on plan drafts as requested; • Inform the public, local officials, and other interested parties about the planning process and provide opportunities for them to comment on the plan; and • Formally adopt the mitigation plan. All of the jurisdictions listed as official participants in this plan met all of these participation requirements. Table 1.1 shows the representation of each participating jurisdiction at the planning meetings, provision of Data Collection Guides, and update/development of mitigation actions. Sign-in sheets are included in Appendix B: Planning Process Documentation. Table 1.1.

The plan update was completed utilizing the 9-task approach within a broad four-phase process: 1) Organize resources, 2) Assess risks, 3) Develop the mitigation plan, and 4) Implement the plan and monitor progress. Into this process, Amec Foster Wheeler integrated a detailed 10-step planning process adapted from FEMA's Community Rating System (CRS) and Flood Mitigation Assistance programs. Thus, the process used for this plan meets the funding eligibility requirements of the Hazard Mitigation Assistance grants and Community Rating System. Table 1.2 shows howthe process followed fits into FEMA's original four-phase DMA process as well as the revised Nine Task Process outlined in the 2013 Local Mitigation Planning Handbook and the 10-step CRS process.

Dubuque County, lowa 17 Multi-jurisdictional Hazard Mitigation Plan 2018 During the kick-off ineeting Amec Foster Wheeler presented information on the scope and purpose of the plan, participation requirements of HMPC members, and the proposed project work plan and schedule. Plans for public involvement (Step 2) and coordination with other agencies and departments (Step 3) were discussed. Amec Foster Wheeler also introduced hazard identification requirements and data needs. The HMPC discussed potential hazards as well as past events and impacts and refined the identified hazards to be relevant to Dubuque County. The hazard ranking methodology utilized by lowa Homeland Security and Emergency Management Department in the State Hazard Mitigation Plan was introduced preliminary information was presented for each hazard identified. Participants were given the Amec Foster Wheeler Data Collection Guide to facilitate the collection of information needed to support the plan, such as data on historic hazard events, values at risk, and current capabilities. Each participating jurisdiction completed and returned the worksheets in the Data Collection Guide to Amec Foster Wheeler. Amec Foster Wheeler integrated this information into the plan, supporting the development of Chapters 2 and 3. Step 2: Plan for Public lnvolvement(Handbook Task 3J 44 CFR Requirement 201.6(b): An open public involvement process is essential to the development of an effective plan. In order to develop a more comprehensive approach to reducing the effects of natural disasters, the planning process shall include: (1) an opportunity for the public to comment on the plan during the drafting stage and prior to plan approval. At the kick-off ineeting, the HMPC discussed options for soliciting public input on the mitigation plan. To provide an opportunity for the public to comment during the drafting stage, the committee determined that the most effective method would be dissemination of a survey. The survey was announced via the following media outlets: City of Dubuque 'Nextdoor' social media post, City of Dubuque Facebook post, City of Dubuque Twitter Tweet, Copies of these announcements are included in Appendix B. The public survey was developed specific to the Dubuque County Mitigation Plan and provided a brief plan summary as well as a questionnaire to capture public and stakeholder input. The survey was made available online as well as in hard copy at the Dubuque County Courthouse, local city halls, and local fire stations. A copy of the survey is provided in Appendix B. In addition, to notification through media outlets described above, committee members distributed the survey to members of the public and key stakeholders in their own jurisdiction. In all, 287 surveys were completed. The survey asked the public and stakeholders to indicate their opinion on the likelihood for each hazard to impact their jurisdiction. They were asked to rate the probability of each hazard profiled in this plan as 1-unlikely, 2-occasional, 3-likely, and 4-highly likely. The summary results of this question are provided in Figure 1.1. Dubuque County, lowa 1.8 Multi-jurisdictional Hazard Mitigation Plan 2018 Figure 1.1.

Also, this would minimize the economic disruptions that can cripple a community over a long period and delay recovery efforts. • Several suggestions in this survey are very relevant regarding strengthening power lines and making sure if river does flood- Hazmat is reacting ASAP to minimize and identify potential damage. Also, suggest funding for re-imbursement of persons who are elderly and have basements flooded because of rain and have to call KANN-DO to bail them out of it. • Because the cost of flood insurance is going up, Dubuque County should consider becoming a Community Rating System (CRS) community. • Infrastructure update such as roads, bridges;, tornado safety rooms in all daycare, public structures, erosion control, runoff issues from farms into ponds • New Building in areas not protected by the floodwall(e.g. Schmidt Island). The public was also given an opportunity to provide input on the final draft of the complete plan. The entire plan draft was made available on the County's website as a PDF document. In addition, a hard copies were made available at the Dubuque County Courthouse and the Epworth City Hall. Dubuque County announced the availability of the entire final draft plan and the two-week final public comment period on the County website. A copy of the announcement is provided in Appendix B. The final public comment period was from July 16 through July 30, 2018; one comment was received and incorporated into the final plan. Dubuque County, lowa 1.12 Multi-jurisdictional Hazard Mitigation Plan 2018 The HMPC invited other targeted stakeholders to comment on the draft plan via an e-mail letter, which is described in greater detail in Step 3: Coordinate with Other Departments and Agencies. Minor comments were received and incorporated. Step 3: Coordinate with Other Departments and Agencies and lncorporate E�cisting lnformation (Handbook Task 3J 44 CFR Requirement 201.6(b): An open public involvement process is essential to the development of an effective plan. In order to develop a more comprehensive approach to reducing the effects of natural disasters, the planning process shall include: (2) An opportunity for neighboring communities, local and regional agencies involved in hazard mitigation activities, and agencies that have the authority to regulate development, as well as businesses, academia and other private and non-profit interests to be involved in the planning process. (3) Review and incorporation, if appropriate, of existing plans, studies, reports, and technical information. There are numerous organizations whose goals and interests interface with hazard mitigation in Dubuque County. Coordination with these organizations and other community planning efforts is vital to the success of this plan. Dubuque County invited neighboring counties, other local, state, and federal departments and agencies as well as institutions of higher learning to the second planning meeting to learn about the hazard mitigation plan update initiative. In addition, the HMPC developed a list of additional stakeholders involved in hazard mitigation activities, to invite by e-mail letter to review and comment on the final draft of the Dubuque County Multi- jurisdictional Hazard Mitigation Plan prior to submittal to the State and FEMA. The stakeholders that were invited to meeting #2 and/or to comment on the final plan draft included in Table 1.4. Dubuque County, lowa 1.13 Multi-jurisdictional Hazard Mitigation Plan 2018 Table 1.4.

This included contact with specific representatives of stakeholder agencies, as well as accessing stakeholder data that has been made available to the public via the internet. Integration of Other Data, Reports, Studies, and Plans In addition, input was solicited from many other agencies and organizations that provided information but were not able to attend planning meetings. As part of the coordination with other agencies, the HMPC collected and reviewed existing technical data, reports, and plans. These included: • lowa Hazard Mitigation Plan (September 2013); • Dubuque County Hazard Mitigation Plan (May 2013); • lowa Watershed Approach, Bee Branch Watershed Flood Mitigation Project and Bee Branch Healthy Homes Resiliency Program (BBHHRP); • National Flood Insurance Program Policy and Loss data; • Flood Insurance Rate Maps for all of Dubuque County; • lowa Department of Natural Resources, Dam Safety Program Inventory of Dams for Dubuque County, available inundation maps; • National Inventory of Dams • National Levee Inventory levee protected areas • Wildland/Urban Interface and Intermix areas from the SILVIS Lab, Department of Forest Ecology and Management, University of Wisconsin; Dubuque County, lowa 1.14 Multi-jurisdictional Hazard Mitigation Plan 2018 • Various local plans such as Comprehensive Plans, Economic Development Plans, Capital Improvement Plans, etc. For a complete list of local plans that were reviewed and incorporated, see Chapter 2; • US Department of Agriculture's (USDA) Risk Management Agency Crop Insurance Statistics. This information was used in the development of the hazard identification, vulnerability assessment, and capability assessment and in the formation of goals, objectives, and mitigation actions. These sources, as well as additional sources of information are documented throughout the plan and in Appendix A, References. Phase 2 Assess Risk (Handbook Task 5) Step 4:Assess the Hazard: ldentify and Profile Hazards Amec Foster Wheeler assisted the HMPC in a process to identify the hazards that have impacted or could impact communities in Dubuque County. At the kick-off meeting, the HMPC examined the history of disaster declarations in Dubuque County, the list of hazards considered in the 2013 lowa State Hazard Mitigation Plan, and the hazards identified in the previous hazard mitigation plan. The committee then worked through this list of all potential hazards that could affect the planning area. They discussed past hazard events, types of damage, and where additional information might be found. The committee identified 19 natural and human-caused hazards that have the potential to impact the planning area. Additional information on the hazard identification process and which hazards were identified for each jurisdiction is provided in Chapter 3. During the kick-off ineeting, the HMPC discussed past events and impacts on a county-wide basis to contribute to the risk assessment update. After the kick-off meeting, each jurisdiction completed a Data Collection Guide, including information on previous hazard events in their community. Utilizing the information from the Data Collection Guides as well as existing plans, studies, reports, and technical information as well as information available through internet research and GIS analysis, a profile was developed for each hazard identified. More information on the methodology and resources used to identify and profile the hazards can be found in Chapter 3. Step 5: Assess the Problem: ldentify Assets and Estimate Losses Assets for each jurisdiction were identified through a combination of several resources. The Dubuque County GIS Department and Assessor's Office provided access to datasets with parcel and building data as well as corporate boundaries, school district boundaries, and other available GIS layers. Population data was obtained from the U.S. Census Bureau. The critical facility inventory was compiled from data layers available from Dubuque County. Methodologies and results of the critical facility analysis are provided in Chapter 3 and Appendix E. Additional assets such as historic, cultural, and economic assets as well as specific vulnerable populations and structures were obtained from a variety of sources as described in Chapter 3. The HMPC also analyzed development since the last plan update and future development trends from data provided by each jurisdiction on the Data Collection Guide as well as data Dubuque County, lowa 1.15 Multi-jurisdictional Hazard Mitigation Plan 2018 available from the U.S. Census Bureau and obtained from jurisdictions through other planning mechanisms such as Comprehensive Plans and Future Development Plans. After profiling the hazards that could affect Dubuque County and identifying assets, the HMPC collected information to describe the likely impacts of future hazard events on the participating jurisdictions. For each hazard, there is a discussion regarding future development as well as climate change impacts regarding how vulnerability to that specific hazard might be impacted in the future. Existing mitigation capabilities were also considered in developing loss estimates. This assessment consisted of identifying the existing mitigation capabilities of participating jurisdictions. This involved collecting information about existing government programs, policies, regulations, ordinances, and plans that mitigate or could be used to mitigate risk from hazards. Participating jurisdictions collected information on their regulatory, personnel, fiscal, and technical capabilities, as well as previous and ongoing mitigation initiatives. This information is included in Chapter 2 Planning Area Profile and Capabilities. Specific capabilities such as participation in the National Flood Insurance Program as well as designation as Fire Wise Communities or Storm Ready Communities and placement of storm sirens are incorporated in the vulnerability analysis discussions, where applicable. Taking into consideration the vulnerability and capability assessments, and where sufficient information was available, a variety of inethods was used to estimate losses for each profiled hazard. For geographic hazards such as river flooding, dam failure, levee failure, and hazardous materials (fixed facilities) specific assets/areas at risk and loss estimates were determined through GIS analysis. For other hazards such as weather-related hazards, loss estimates were developed based on statistical analysis of historic events. For some human- caused hazards, loss estimates were scenario-based. The methodologies for each loss estimate are described in detail in Chapter 3. Within each hazard section, the text provides details on how the hazard varies by jurisdiction, where applicable. In addition, at the conclusion of each hazard section, a summary table indicates the specific probability, magnitude, warning time, and duration rating of the hazard for each jurisdiction is provided to show how the hazard varies. Where applicable, introductory text preceding the table highlights noted variables. Results of the preliminary risk assessment were presented at Meeting #2 and the Draft Risk Assessment (Chapter 3) was provided to the HMPC for review and comment. Several comments, corrections, and suggestions were provided to Amec Foster Wheeler and incorporated into the risk assessment as appropriate. Phase 3 Develop the Mitigation Plan (Handbook Task 6) Step 6: Set Goa/s Amec Foster Wheeler facilitated a discussion session with the HMPC during Meeting #2 to review and update goals. Common categories of mitigation goals were presented as well as the 2013 State Hazard Mitigation Plan goals. This planning effort is an update to an existing hazard mitigation plan. As a result, the goals from the 2011 Dubuque County Hazard Mitigation Plan were reviewed. Dubuque County, lowa 1.16 Multi-jurisdictional Hazard Mitigation Plan 2018 The validated goals for this plan update are provided below: • Goal 1: Increase capabilities within Dubuque County entities to mitigate the effects of hazards by enhancing existing or designing and adopting new policies that will reduce damaging effects of hazards. • Goal 2: Protect the most vulnerable populations, buildings and critical facilities within Dubuque County through the implementation of cost effective and technically feasible mitigation projects. • Goal 3: Improve the level of responder, government, business and citizen awareness and preparedness for disasters. • Goal 4: Develop programs to assure that response agencies, governments, educational institutions and local businesses are able to operate during times of disaster. Step 7: Review Possib/e Activities At meeting #2, a handout of previous actions was provided to all jurisdictions with instructions to provide updates for each action. Jurisdictions were encouraged to maintain a focused approach and continue forward only those actions that are aimed at implementing long-term solutions to prevent losses from hazards. The focus of Meeting #3 was to update the mitigation strategy by discussing relevant new actions considered necessary as a result of the updated risk assessment. The HMPC reviewed the following: plan goals, previous actions from the 2011 plan, key issues from the risk assessment, lowa Homeland Security and Emergency ManagemenYs HMA funding priorities, public opinion survey results on types of actions desired, and FEMA's Mitigation Action Ideas publication. The group discussed the types of mitigation actions/projects that could be done by the jurisdictions in Dubuque County. Consideration was given to the analysis results provided in the risk assessment and the anticipated success for each project type. Projects relating to emergency response were discussed, but participants were encouraged to focus on long-term mitigation solutions since response-related mitigation actions occur on a routine basis as requirements of other plans. Complex projects that would necessitate use of large numbers of county resources were also discussed. This opportunity to discuss a broad range of mitigation alternatives allowed the jurisdictions to understand the overall priorities of the committee and to allow for discussion of the types of project most beneficial to each jurisdiction. As part of this discussion, consideration was given to the potential cost of each project in relation to the anticipated future cost savings. The jurisdictions were also provided instructions for completing the Mitigation Action Plan for each continuing and newly developed action. A modified form of the STAPLEE prioritization tool was also provided to assist jurisdictions in determining the prioritization that should be assigned to each action. To provide a current, comprehensive and consistent prioritization approach, all continuing and new actions were evaluated using the modified STAPLEE prioritization tool for the plan update. The details from the Action Plan for each Continuing and New action are provided in Chapter 4. The completed and deleted actions are provided in Appendix C. Chapter 4 provides additional details regarding the process undertaken to refine the mitigation strategy to make Dubuque County and its jurisdictions more disaster resistant. Dubuque County, lowa 1.17 Multi-jurisdictional Hazard Mitigation Plan 2018 Step 8: Draft an Action Plan A complete draft of the plan was made available online and in hard copy for review and comment by the public, other agencies and interested stakeholders. This review period was from July 16 to July 30, 2018. Methods for inviting interested parties and the public to review and comment on the plan were discussed in Steps 2 and 3, and materials are provided in Appendix B. Comments were integrated into a final draft for submittal to the lowa Homeland Security and Emergency Management Division and FEMA. Phase 4 Implement the Plan and Monitor Progress Step 9:Adopt the Plan (Handbook Task 8J To secure buy-in and officially implement the plan, the governing bodies of each participating jurisdiction adopted the plan. Scanned copies of resolutions of adoption are included in Appendix D of this plan. Step 10: lmplement, Evaluate, and Revise the Plan (Handbook Tasks 7 & 9J The HMPC developed and agreed upon an overall strategy for plan implementation and for monitoring and maintaining the plan over time during Meeting #3. This strategy is described in Chapter 5, Plan Maintenance Process.

The County is bordered by Jackson and Jones counties on the south, Delaware County on the west, and Clayton County on the north. The County contains a land area of 617 square miles, or 391,680 acres. The County has 17 townships and 21 incorporated cities, the most incorporated cities of any other county in lowa. Dubuque County,lowa 2.2 Multi-jurisdidional Hazard Mitigation Plan 2018 The county seat is Dubuque, lowa, which is located along the Mississippi River in the east- central portion of the county. Eastern Dubuque County is markedly different from the western portion in that its topography is very uneven. The city of Dubuque and surrounding areas adjacent to the Mississippi River have many steep hills, bluffs, and ravines. Also, the eastern portion is more heavily wooded than the west, which is mostly rolling farmland. Dubuque County is widely-known for its impressive bluffs along the Mimssissippi River, which run along the entire length of the county's riverbanks. These form part of lowa's Coulee Region, otherwise known as the Drifftless Area. Adjacent counties: • Clayton County (north) • Grant County, Wisconsin (northeast), across the Mississippi River • Jo Daviess County, Illinois (east), across the Mississippi River • Jackson County (southeast) • Jones County (southwest) • Delaware County (west) 2.1.2 Major Rivers and Watersheds The four major watersheds in Dubuque County are Grant-Little Maquoketa, Turkey, Apple- Plum, and Maquoketa. Major rivers in Dubuque include: Mississippi River; Caffish Creek; South Fork, Middle Fork, and North Fork Catfish Creek; Little Maquoketa River. There are four HUC-8 watersheds that Dubuque County crosses (see Figure 2.2): • Grant-Little Maquoketa, 0706003 • Turkey, 0706004 • Apple-Plum, 07060005 • Maquoketa, 07060006 Dubuque County,lowa 2.3 Multi-jurisdictional Hazard Mitigation Plan 2018 Figure 2.2.

It is named for Julien Dubuque, the first European settler of lowa. It is one of lowa's two original counties along with Des Moines County; both were organized by the MichiganTerritorial legislature in 1834. The city of Dubuque, the county seat, was chartered in 1833 as the first city in lowa. 2.1.4 Climate Dubuque County, like the entire state of lowa, is within the humid continental zone. The mean temperature of the county in the summer months is 70.1 degrees Fahrenheit and 21.8 degrees Fahrenheit in the winter. Seasons fluctuate from being very wet to very dry, and temperatures can fluctuate greatly in spring and autumn months. Average annual precipitation is approximately 36 inches.

According to the 2015 estimates, 6.2 percent of the population is under age 5 and 15.8 percent of the population is over age 65 in Dubuque County. According to the 2015 5-year American Community Survey, there were 37,891 households with an average household size of 2.41 people. The Hazards and Vulnerability Research Institute at the University of South Carolina developed the Social Vulnerability Index (SoVI O) to evaluate and rank the ability to respond to, cope with, recover from, and adapt to disasters. The index synthesizes 30 socioeconomic variables, which the research literature suggests contribute to reduction in a community's ability to prepare for, respond to, and recover from hazards. SoVI O data sources include primarily those from the United States Census Bureau. Figure 2.4 shows that Dubuque County has a low Social Vulnerability Index. The low index indicates that Dubuque County is generally able to cope and recover from disasters. Dubuque County,lowa 2.6 Multi-jurisdictional Hazard Mitigation Plan 2018 Figure 2.4.

According to the 2012 Census of Agriculture there were 1,462 farms in the County covering 291,441 acres of land (74.9 percent of the 608 Sq. miles of land area (389,120 acres) in the County). Crop and livestock production are visible parts of the agricultural economy, but many related businesses contribute by producing, processing, and marketing farm and food products. These businesses generate income, employment and economic activity throughout the region. Farms on average were 199 acres. Dubuque County agriculture and agriculture-related industries provide 5,057 jobs, representing 7.30 percent of the County's workforce.

Dubuque's 6.5 square mile Bee Branch Watershed drains to the Bee Branch Creek and is located entirely within the city limits of Dubuque. This watershed area includes the city's most developed areas where over 50% of Dubuque residents either live or work. The watershed encompasses historic neighborhoods offering some of the community's most affordable workforce housing. This area is also hit hardest by flash flooding during significant rain events with much more than "just a little water in the basement." In January 2016, the U.S. Department of Housing and Urban Development (HUD) announced an award of nearly $97 Million to the state of lowa for its proposal titled, The lowa Watershed Approach for Urban and Rural Resilience. The award was made under HUD's National Disaster Resilience Competition designed to fund cutting-edge projects that address unmet needs from Dubuque County,lowa 2.10 Multi-jurisdictional Hazard Mitigation Plan 2018 past disasters while addressing the vulnerabilities that could put Americans in harm's way during future disasters. The lowa Watershed Approach (IWA) represents a program through which lowans are working together to address factors that contribute to floods. This approach is consistent with other statewide programs in lowa to reduce flooding and improve water quality, such as the lowa Flood Mitigation Program and the lowa Nutrient Reduction Strategy. Nine distinct watersheds representing different lowa landforms will serve as project sites for the IWA. Each will form a Watershed Management Authority, develop a hydrologic assessment and watershed plan, and implement projects in the upper watershed to reduce the magnitude of downstream flooding and to improve water quality during and after flood events. Flood resilience programs will be implemented in each watershed to help increase community resilience to future floods. The nine project watersheds are: • Upper lowa River Watershed—includes a portion of Howard County • Upper Wapsipinicon River Watershed—includes a portion of Howard County • Bee Branch Creek (Dubuque) Watershed • Middle Cedar River Watershed • Clear Creek Watershed • English River Watershed • North Raccoon River Watershed • East Nishnabotna River Watershed • West Nishnabotna River Watershed The IWA will accomplish six specific goals in each watershed: 1) reduce flood risk; 2) improve water quality; 3) increase flood resilience; 4) engage stakeholders through collaboration and outreach/education; 5) improve quality of life and health, especially for susceptible populations; and 6) develop a program that is scalable and replicable throughout the Midwest and the United States. Through the IWA Flood Resilience Program, a Flood Resilience Action Plan will be created for each watershed about how to prepare, mitigate, respond, and recover from flood events. This will help communities qualify for disaster mitigation funding during the 5-year project as well as recurring planning efforts required by the federal government. No one organization in lowa has the capacity to implement the entire IWA program. Thus, IWA's success is dependent on the collaboration of many partners who helped to conceptualize the program and the many more who will help to develop and implement its many components. Funded partners and their roles or expertise include: • lowa Economic Development Authority: Direct recipient of the HUD grant funds and overall program administration • Homeland Security and Emergency Management: Aid in outreach and education activities for public resilience programs and development of planning documents and technical assistance Dubuque County,lowa 2.11 Multi-jurisdictional Hazard Mitigation Plan 2018 • City of Dubuque: Implementation of watershed projects and Healthy Homes program in the Bee Branch • University of lowa: Program lead for watershed projects implementation and monitoring (water quantity and quality), resilience programming, and assessment • lowa State University: IWA outreach programming and monitoring of watershed projects success (soil erosion and transportation) • University of Northern lowa: IWA outreach programming • lowa Department of Natural Resources: Direct resource to watersheds for formation of watershed management authorities and capacity building • lowa Department of Agriculture and Land Stewardship: Direct resource to watersheds for assistance with implementing watershed projects. • Cities of Coralville and Storm Lake: Implementation of built projects in their cities • Benton, Buena Vista, Fremont, lowa, Johnson, Mills, Winneshiek, and Howard Counties: Fiscal agents for the work in their respective watersheds. Dubuque/Bee Branch Watershed Approach Details The Bee Branch Creek Watershed has experienced significant flooding from stormwater during heavy rain events, including six Presidential Disaster Declarations since 1999. Many homeowners have experienced flooding on such a regular basis that they have fallen behind on repairs, suffer from chronic mold and mildew problems, and live with residual structural issues. The Bee Branch Healthy Homes Resiliency Program (BBHHRP) will provide support and resources for residential properties to make repairs and implement onsite stormwater management principles. The BBHHRP will improve housing conditions and make homes more resilient to future flooding. The Bee Branch Healthy Homes (BBHH) Resiliency Program includes $8.4 million in the form of 5-year forgivable loans to improve 320 housing units, including owner-occupied homes, single-unit rentals, and small, multi-family residential units. Funds will be awarded to properties where low- to moderate- income residents reside and used to make repairs and renovations to decrease environmental health and safety issues from flooding. In addition to the BBHHRP, the Bee Branch Watershed will also include infrastructure improvements in the watershed that will help to mitigate flood damage including storm sewer capacity improvements and tunneling culverts through a railroad right-of-way to complete the restoration of the Bee Branch Creek. This project consists of several infrastructure improvements that will reduce the volume of stormwater, slow the rate of stormwater through the upper watershed, increase the safe conveyance of stormwater through the flood-prone area, and provide floodwater protection to the City's water treatment plant on Hawthorne Street. In December 2013, the project was awarded $98.5 million from the lowa Flood Mitigation Board in the form of state sales tax increment financing spread over the next 20 years. This is the largest amount ever awarded to the City of Dubuque and will enable the City to issue debt to implement the comprehensive flood mitigation plan much sooner than previously anticipated at a lower cost to Dubuque citizens and businesses. Dubuque County,lowa 2.12 Multi-jurisdictional Hazard Mitigation Plan 2018 In January 2016, the U.S. Department of Housing and Urban Development (HUD) awarded the City of Dubuque $31.5 million in disaster resiliency funds for the Bee Branch Healthy Homes Resiliency Program and stormwater infrastructure improvements. When combined with other state and federal grants and local donations, the City has received $160 million to help fund the $219 million project. Additional funding sources are being explored. Project Lead: City of Dubuque The timeline for this program runs from the award in 2016 through 2021.

US Highways 61 and 151, running north south, enter from the south and cross the Mississippi on the east. US Highway 52 enters from the south near the Mississippi and runs northwest through the county. State Highway 136 runs north and south close to the western border. Numerous paved county roads connect all of the incorporated cities and unincorporated villages throughout the county. • U.S. Highway 20 • U.S. Highway 52 • U.S. Highway 61 • U.S. Highway 151 • lowa Highway 3 • lowa Highway 32 • lowa Highway 136 Additional details of transportation systems in Dubuque County are provided in Section 3.5.19, Transportation Incident. 2.2 City/County Capabilities Unincorporated Dubuque County is governed by a 3-member Board of Supervisors. Each incorporated city is governed by a five-member Mayor/City Council. Dubuque County has an active Emergency Management Commission that coordinates emergency management capabilities in the County. Dubuque County participates in the Emergency Notification System (CCENS), part of the Alert lowa system contracted with WENS Inspiron. All jurisdictions within the County have the ability to utilize this service. The following spections provide additioinal information about each jurisdiction including: Description, Land Use and Development, Technical and Fiscal Resources / Other Mitigation Capabilities, Dubuque County,lowa 2.13 Multi-jurisdictional Hazard Mitigation Plan 2018 2.2.1 .1 Unincorporated Dubuque County Description The unincorporated areas of Dubuque County are primarily agricultural based. The topography varies through the County and the associated land capabilities drive the type of farm-based enterprises that operate in a given location. Numerous major US and state highways run through Dubuque County. The City of Dubuque is the major hub for the four-lane US Highway 20 that runs east west through Dubuque County extending into lowa and Illinois. Four-lane US Highway 61 extends north south from the City of Dubuque and extending into Wisconsin on the north and to the Quad Cities and beyond to the south. Four-lane US Highway 151 extends from the City of Dubuque and into Wisconsin on the north and to Cedar Rapids and beyond to the southwest. US Highway 52 runs north-south generally following the Mississippi River and extending north from Dubuque County through lowa into Minnesota and to the south through Bellevue and Sabula before entering into Illinois. Land Use and Development Dubuque County contains a land area of 617 square miles, or 391,680 acres. The County has 17 townships and 21 incorporated cities. The City of Dubuque is the county seat and is located on the east edge of the county along the west bank of the Mississippi River. Dubuque County is ranked as the 7�h most populated county in lowa. There are 3 four-lane highways that provide access into the county: US Highway 20, US Highway 151 and US Highway 61 South. Additionally, there are two main two-lane highways that provide access into and around the county: US Highway 52 and lowa Highway 136 which is on the west end of the county. These five highways provide access to three-quarters of the cities in the County. The Dubuque Regional Airport is located in the County, south of the Cityof Dubuque. It is accessed by US Highway 61 South and recently underwent a $40 million renovation for a new terminal and access road. There are seven county parks, six preserves and one state park and one preserve in the County. The County also operates one golf course and maintains 26 miles of a hike and bike trail called Heritage Trail that was part of an old abandoned railroad right of way. Flooding occurs frequently in the County and affects mostly farm fields, roads and bridges, including bridges along the Heritage Trail. These floods can be very costly so some of the old railroad bridges along Heritage Trail have been replaced by newer designs that allow the water to flow more freely and reduce flood damage. Agricultural Land Use The County's primary land use is agricultural and is found throughout the unincorporated areas of the County. The topography ranges from gently undulating relief in the southwest portion of the County, to hilly and steep relief in the north and eastern portions of the County. Along the Mississippi River and its tributaries, the topography is very steep and rugged, with high limestone bluffs and outcrops. Much of this area containing the steep terrain is heavily wooded. Dubuque County,lowa 2.14 Multi-jurisdictional Hazard Mitigation Plan 2018 The steep landscape has restricted development and farming activities to some extent. About 20% of the single-family homes that have recently been built in the County have been placed on agricultural land. Residential Land Use Residential development in the County's unincorporated areas have generally occurred according to previously established development patterns and most recently is following the Future Land Use Development Map. Residential uses are primarily located near incorporated cities, along major highway and roadway corridors and are found in clusters up and down the Mississippi River. Most of the new residential growth in the County is occurring within 2-4 miles of the City of Dubuque and near the larger cities in the county, such as Cascade, Dyersville, Epworth, Farley and one of the fastest growing city in the state, Peosta. Commercial Land Use Commercial development is located mostly along the highway corridors with most of the commercial uses found along US Highways 151 and 61 south from the City of Dubuque to the Airport, along US Highway 20 from the Dubuque City limits to Peosta and along US Highway 52 from the City of Dubuque to Mud Lake Road. Some new commercial development is occurring in the flood plain along the Couler Valley and Little Maquoketa River north of the City of Dubuque. Property owners are filling in the old barrow pits along Highway 52 North that are in the flood plain and then marketing the property for new commercial and industrial uses. The County is looking into amending the Flood Plain Management Ordinance to restrict the filling in of flood plain and to reduce the occurrence of flooding in that area and in the County as a whole. Industrial Land Use Industrial uses in Dubuque County are primarily located in three areas around the City of Dubuque. The first area is to the south along Highways 52, 151 and 61. New development is occurring in Tamarak Park and near the airport. Another industrial area is located west of the City of Dubuque along Highway 20. This area is mostly developed from the Dubuque city limits to Peosta. The third area is along Highway 52 North in the Couler Valley and Little Maquoketa River outlet to the Mississippi River. John Deere Dubuque is located just outside the flood plain of the Little Maquoketa River. Over the last few years, Flood Plain Permits have been issued for filling in the flood plain along Highway 52 North. Some older more established businesses are seeing flooding in the Couler Valley watershed that have not flooded before. New development will occur along this corridor until the Flood Plain Management Ordinance is amended to restrict filling in and development of the flood plain in this area. Both the South and West commercial and industrial corridors will be affected by the proposed four-lane highway, the Southwest Arterial that will be built in the next 10 -15 years between US Highways 151/61 and US Highway 20. Residential, commercial and industrial development is expected to occur from the city limits on the southwest side of the City of Dubuque to beyond the Southwest Arterial after the new highway is built. This change in land use will be put into the Future Land Use Development Map at some future date as construction of the highway is nearing completion. Dubuque County,lowa 2.15 Multi-jurisdictional Hazard Mitigation Plan 2018 Comprehensive Land Use Development Plan and Map Dubuque County's Comprehensive Land Use Development Plan and Map is the community's guide to future development of the unincorporated areas of Dubuque County. The development plan and map guide development decisions made by the Board of Supervisors. The Comprehensive Land Use Development Plan is not an ordinance. It contains the long-range goals and objectives for the County that was compiled after several public meetings and hearings to determine a community vision for the future of Dubuque County. The first Comprehensive Plan for the County was adopted on January 21, 1969 and was updated and readopted on September 23, 2002. The Comprehensive Plan was updated again in 2011-2012 to incorporate the 10 Smart Planning Principles and 13 Comprehensive Planning Elements adopted by the State of lowa during their last legislative session. This update aimed to further protect property in the County from flood hazards. The elements of the current Comprehensive Plan include: • Planning and Land Use Development • Natural, Environmental and Resource Management • Public Facilities and Services • Transportation • Future Land Use Development Map Technical and Fiscal Resources / Other Mitigation Capabilities Revenues for governmental uses flow primarily from property taxes collected. There is a local sales tax that generates revenues for road and street departments. Government services are organized by the followed elected officials: Board of Supervisors (3); Sheriff, Recorder, Treasurer, Auditor and County Attorney (1 each). Dubuque County's roads are developed and maintained by the County Engineer's Office and staff. Other recreation facilities and opportunities are organized and provided by the Dubuque County Conservation Department and staff. 2.2.1 .2 Asbury Description The City is located in eastern Dubuque County, adjacent to the west side of the City of Dubuque. Asbury is located north of US Highway 20, south of US Highway 52. The Northwest Arterial Road connects Asbury's main thoroughfare, Asbury Road, with US Highways 20 and 52. Land Use and Development While the late 1990s saw the greatest growth to date in the city, Asbury continues to grow at a substantial rate. In the past few years the City has annexed the following areas: Sandwedge, Dubuque County,lowa 2.16 Multi-jurisdictional Hazard Mitigation Plan 2018 Sandpiper, Berry Lane, Mill Creek, Brick Mason Lane, and areas off of Hales Mill Road. The City of Asbury purchased the 152-acre Meadows Golf Course and annexed another 160 acres west of the course for Tuscany Ridge and Legacy subdivisions in 2009. The most active areas of growth in the City of Asbury are Carver Heights and Clay Ridge subdivisions, which are both near the new Dubuque public elementary and middle schools. The City of Asbury has a Comprehensive Land Use Plan. The plan was last updated in 2013. Technical and Fiscal Resources / Other Mitigation Capabilities The City has a city hall staff of three full-time and one part-time employee. The Public Works Department has four full-time employees and two seasonal employees. The Police Department has four full-time employees and two part-time employees. Engineering services are contracted. Revenues are provided through property taxes, local option sales tax, and user fees. The City has the ability to issue general obligation bonds and revenue debt. The Asbury Community Fire Department is a member of the Dubuque County Emergency Medical Services Association and Asbury is a partner in the EMS Mutual Aid Agreement.

The city currently has a land area of 31.06 square miles. As the largest city in the tri-state area, Dubuque serves as the major retail, medical, education and employment center for the tri-state area estimated at 250,000 people. The community has a stable and diversified manufacturing base, a growing service sector, and a significant increase in technology based companies. Dubuque also has key employment in publishing, health care, tourism and education. Tourism continues to be a major economic force with over 1.5 million visitors annually. Land Use and Development In the early 1900s, most of Dubuque was located below the bluff lines in the historic floodplain carved by the Mississippi River between the limestone bluffs. The Mississippi River was the focus of the community, primarily as a transportation artery. Most of the city's key industries were located adjacent to or near the river. Rail lines served as conduit to the rest of the nation, concentrated in areas near the Mississippi River. The city's commercial hub was concentrated along Main Street, populated by the giants of the retail industry at the time. Residential development also was concentrated below the bluffs, although an increasing number of homes and institutions were built west on the bluff tops in areas heading to the north, south and west. The town had distinct geographic areas defined not only by prominent land forms but also ethnic concentrations. The city's development pattern did not substantially change until the 1950s and 1960s, when, like much of America, Dubuque entered an era of growth and prosperity that fueled substantial changes to development patterns which saw the decline of Main Street as the commercial core of the city, and the rise of the John F. Kennedy Road corridor and Kennedy Mall as the primary commercial shopping area. Long-time industries along the riverfront closed or relocated to the Dubuque County,lowa 221 Multi-jurisdictional Hazard Mitigation Plan 2018 west end. Hundreds of new housing units were constructed in suburban development patterns on the west and north edges of Dubuque. This pattern of westward expansion for industry, commercial and residential development continued until the 1980s. The community then worked to expand and diversify its local economy, and to obtain transportation and communication connections with the nation and the world; through these efforts, the development and pattern of Dubuque again began to change significantly. New highway construction provided Dubuque with better connectivity to the large Midwestern cities and the interstate highway system. The City of Dubuque has annexed thousands of acres since 2000 to provide opportunities for additional residential, commercial and industrial growth. Additional local industries were relocated to new industrial parks developed on the city's south and west ends during the 1990s and new residential developments began on the south side of the city as well as the west end. With construction of the Northwest Arterial (Highway 32) the new commercial retail center shifted to Asbury Plaza Shopping Center. In addition to extending City services for new industrial parks, Dubuque has maintained its commitment to neighborhood and downtown revitalization. As part of the city's economic rebirth, the community also looked back to a long- neglected attribute — its historic architecture. Downtown became the center for financial, insurance and other service oriented commercial uses, and then for arts, culture, and entertainment. The riverfront was dramatically transformed from industrial brownfields to an area for recreation and entertainment with the redevelopment of the Port of Dubuque beginning in 2000. There has been a continuing trend of redevelopment in the downtown and surrounding commercial and residential areas, such as the Washington and North End Neighborhoods and the historic Dubuque Millwork District. Technical and Fiscal Resources / Other Mitigation Capabilities The community of Dubuque is a metropolitan service area for seven surrounding counties. Dubuque is connected by four-lane highways to Davenport, Des Moines, Madison and Minneapolis. The majority of the way to Chicago is also four-lane highway. The City's annual operating and capital budget is over $181 million and funds a full range of municipal services. The City has more than 680 FTE employees. The City of Dubuque provides public safety, public works, health, engineering, cultural, recreation, community development, housing, planning, zoning, inspection, community and economic development services to its citizens. The City provides water, sanitary sewer, storm sewer, solid waste collection, parking (ramps, lots and meters), transit, civic center, convention center, golf course, parks, pools, trails, cable TV programming, public library and airport operations. The City operates the sanitary landfill with Dubuque County. The City's web site is www.citvofdubuque.orq. Dubuque's first Comprehensive Plan was adopted in 1936. The Comprehensive Plan is Dubuque's principal guide for future development, public policies and decision making. The current plan was adopted in 1995, and then updated in 2002 and again in 2008. Dubuque County,lowa 2.22 Multi-jurisdictional Hazard Mitigation Plan 2018 The City's 2001 Drainage Basin Master Plan is a planning study that identifies a generalized area that appears to be at risk from storm sewer backups or overflows. The Drainage Basin Master Plan was intended to address storm sewer conveyance problems — not flooding associated with a creek or river. Storm water system improvements are funded in part by a local stormwater utility. The previous Hazard Mitigation Plan was approved in 2011 and was updated to incorporate into the Multi-Jurisdictional Plan. The City is a participant in the National Flood Insurance Program. The 1965 Mississippi River flood was the great motivator to build Dubuque's floodwall and levee system. The River rose to a record 26.8 feet, flooding downtown and causing millions of dollars in damage. The $12.5 million flood control project was begun in 1968, and completed in time to prevent flooding from the 1973 flood which crested at 21.9 feet. The floodwall system includes 5 miles of earthen levees and 1.4 miles of concrete walls that provide 30-foot flood stage protection with a 3-foot freeboard. FEMA certified Dubuque's floodwall and levee system in 2011 as providing protection from the 100-year flood. Dubuque was the first community in lowa to join the National Flood Insurance Program (NFIP) on April 2, 1971. The City has regulated floodplain development since 1990. Dubuque has been very conscientious in following the NFIP requirements. The city has never approved a variance from the NFIP requirements. The City has not allowed a single new residential structure to be built in any flood hazard area. The only new structures built in flood hazard areas have been commercial structures elevated and/or flood proofed in compliance with the NFIP requirements. The City of Dubuque adopted revised floodplain development regulations in 2011 based on the latest digital flood insurance rate maps (DFIRMs) and flood insurance study (FIS) prepared for the community by FEMA. The history of localized street flooding and basement flooding experienced in the North End of Dubuque (dating from the late 1800s) is the focus of drainage basin improvements like the Bee Branch Creek Restoration Project. This multi-year project replaces an underground storm sewer with an open waterway and other public amenities, reducing the risk of flood damage to 1,150 properties and improving water quality in some of Dubuque's oldest neighborhoods. The City also has installed upstream storm water management facilities to alleviate problems with the storm water system such as the Carter Road dam and 32"d Street detention areas that address existing storm water issues. The City of Dubuque participated with all other cities and school districts within Dubuque County as a member of the lowa Mutual Aid Compact (IMAC). IMAC is established in lowa Code Section 29C.22. See Section 2.1.9 for a summary of the lowa Watershed Approach and specific initiatives in the Bee Branch Watershed in Dubuqe.

Land Use and Development Early development within Dyersville grew around the North Fork Maquoketa River and along First Avenue (old US Highway 20). As the City grew and the highway was relocated to the south edge of the City, residential development spread to the east and north and the commercial development grew along the north edge of US Highway 20 and adjoining State Dubuque County,lowa 2.24 Multi-jurisdictional Hazard Mitigation Plan 2018 Highway 136. Development trends continue to move away from the floodplain area. In recent development, a new subdivision and school have been approved on the west side of Dyersville, while a two- phase residential subdivision on the north side of the city is in process. Also, south of US Highway 20 another residential subdivision has been approved. The City adopted a zoning ordinance, including floodplain regulations in November 1977. The City continues to enforce the floodplain provisions and is in the process of updating the ordinance. The 1999, 2002 and 2008 floods resulted in the City pursuing federal funds for the acquisition and demolition of flood-damaged properties. All properties were located in the 100-year floodplain that is generally west of the North Fork Maquoketa River and extends from approximately five blocks south of First Avenue to the north edge of the City. Damaged properties included residential and commercial properties. Initially the 1999 application requested funds for all properties in the floodplain. Upon review and discussion with lowa Homeland Security and Emergency Management staff, the application was reduced to include 13 flood damaged properties. Through a grant and follow-up amendments, the City acquired 8 properties and received additional funds in 2003 to acquire four more properties through that program. (Note: One property was later added to the original application due to structural damage occurring one year after the flood and two owners withdrew from the application.) A June 2002 flood resulted in a follow-up application for additional funding to acquire properties that were damaged in 2002. While the impacts of this flood were diminished in that 8 structures were removed from the floodplain prior to this flood, the application included an additional 45 damaged properties. Due to funding limitations, the application was revised to 34 properties. The City received funding to acquire and demolish 8 flood-damaged properties. From the June 2008 flood, 37 applicants were identified. Following the 2010 flood, no new applicants were identified; however, several applicants previously identified in 2008 opted to take the buyout. Comprehensive Land Use Plan The City of Dyersville has a Comprehensive Land Use Plan that was first adopted in 1962, and it was updated in 1974 and 1975 as the Comprehensive Development Plan for Dyersville, lowa Planning Area.

Summary.....................................................................................................................3.224 Dubuque County, lowa 3.1 Multi-jurisdictional Hazard Mitigation Plan 2018 44 CFR Requirement §201.6(c)(2): [The plan shall include] A risk assessment that provides the factual basis for activities proposed in the strategy to reduce losses from identified hazards. Local risk assessments must provide sufficient information to enable the jurisdiction to identify and prioritize appropriate mitigation actions to reduce losses from identified hazards. The risk assessment process identifies and profiles relevant hazards and assesses the exposure of lives, property and infrastructure within Dubuque County, lowa to these hazards. The goal of the risk assessment is to estimate the potential loss in the planning area, including loss of life, personal injury, property damage and economic loss, from a hazard event. The risk assessment process allows communities in the planning area to better understand their potential risk to the identified hazards and provides a framework for developing and prioritizing mitigation actions to reduce risk from future hazard events. The risk assessment for Dubuque County and participating jurisdictions followed the methodology described in the 2013 FEMA Local Mitigation Planning Handbook, which includes a four-step process: Step 1—Describe Hazards Step 2—Identify Community Assets Step 3—Analyze Risks Step 4�ummarize Vulnerability This chapter is divided into six main parts: • Section 3.1 Hazard Identification identifies the hazards that threaten the planning area and the methodology utilized to score or rank the hazards; • Section 3.2 Assets at Risk provides the planning area's total exposure to natural hazards, considering critical facilities and other community assets at risk; • Section 3.3 Development Since 2013 Plan Update discusses what changes in development have occurred since the previous Hazard Mitigation Plan; • Section 3.4 Future Land Use and Development discusses areas of planned future development; • Section 3.5 Hazard Profiles and Vulnerability for each hazard, this section is divided into two parts: 1) Hazard Profile discusses the threat to the planning area, the geographic location/extent at risk, previous occurrences of hazard events and probability of future occurrence; and 2) Vulnerabilitv Assessment further discusses specific assets at risk as well as loss estimates. Specifically, where data is available, this section defines and quantifies populations, buildings, critical facilities and other community assets at risk to natural hazards with estimates of potential losses to those assets, where possible; • Section 3.6 Hazard Analysis Summary provides a tabular summary of the hazard ranking for each jurisdiction in the planning area. Dubuque County, lowa 32 Multi-jurisdictional Hazard Mitigation Plan 2018 3.1 Hazard Identification Requirement §201.6(c)(2)(i): [The risk assessment shall include a] description of the type...of all natural hazards that can affect the jurisdiction. The hazards identified for this plan update are listed below in alphabetical order • Animal/Plant/Crop Disease • Dam/Levee Failure • Drought • Expansive Soils • Extreme Heat • Flash Flood • GrassMlildland Fire • Hazardous Materials • Human Disease • Infrastructure Failure • Landslide • Radiologicallncident • River Flooding • Severe Winter Storm • Sinkholes • Terrorism • Thunderstorm/Lightning/Hail • TornadoMlindstorm • Transportation Incident Sections 3.1.1 through 3.1.3 describe how these hazards were identified for this plan update. 3.1.1 Review of Existing Mitigation Plans Prior to 2012, Hazard Mitigation Planning in Dubuque County was implemented on a jurisdictional basis. In 2012 the unincorporated county and incorporated municipalities came together to coordinate multi-jurisdictional mitigation planning for the entire Dubuque County planning area. This coordinated effort resulted in the Dubuque County, lowa Multi-Jurisdictional Hazard Mitigation Plan, approved by FEMA on May 7, 2013. To identify hazards to include in the Risk Assessment update, a comparison was performed between the hazard identification in the 2013 lowa State Hazard Mitigation Plan and the 2013 Dubuque County Multi-Jurisdictional Hazard Mitigation Plan. Table 3.1 provides the details of the comparison. Dubuque County, lowa 3.3 Multi-jurisdictional Hazard Mitigation Plan 2018 Table 3.1.

Federal and/or state declarations may be granted when the severity and magnitude of an event surpasses the ability of the local government to respond and recover. Disaster assistance is supplemental and sequential. When the local governmenYs capacity has been surpassed, a state disaster declaration may be issued, allowing for the provision of state assistance. If the disaster is so severe that both the local and state governments' capacities are exceeded; a federal emergency or disaster declaration may be issued allowing for the provision of federal assistance. FEMA also issues emergency declarations, which are more limited in scope and do not include the long-term federal recovery programs of major disaster declarations. Determinations for declaration type are based on scale and type of damages and institutions or industrial sectors affected. Table 3.2 lists federal disaster declarations that included Dubuque County for the period from 1965 to 2016. Dubuque County, lowa 3.4 Multi-jurisdictional Hazard Mitigation Plan 2018 Table 3.2.

In addition to EM eligibility, other emergency assistance programs, such as Farm Service Agency (FSA) disaster assistance programs, have historically used disaster designations as an eligibility requirement trigger.

The hazards identified for this plan update are listed below in alphabetical order • Animal/Plant/Crop Disease • Dam/Levee Failure • Drought • Expansive Soils • Extreme Heat • Flash Flood • GrassMlildland Fire • Hazardous Materials • Human Disease • Infrastructure Failure • Landslide • Radiologicallncident • River Flooding • Severe Winter Storm • Sinkholes • Terrorism • Thunderstorm/Lightning/Hail • TornadoMlindstorm • Transportation Incident Of the 20 hazards identified in the 2013 State Hazard Mitigation Plan, the following was eliminated from further review: • Earthquake—The planning area is located in a low risk zone for earthquake (Source: USGS; DNR). According to planning committee, no real impacts experienced or expected; this hazard was not included in the 2013 Dubuque County Hazard Mitigation Plan. Additionally, to maintain consistency and to facilitate the roll-up or summarization of hazards in the next State Plan Update, it was agreed that the hazard grouping/hazard naming for this update will be consistent with the 2013 State Plan. 3.1.5 Multi-Jurisdictional Risk Assessment For this multi-jurisdictional plan, the risks are assessed for each jurisdiction where they deviate from the risks facing the entire planning area. The planning area is fairly uniform in terms of climate and topography as well as building construction characteristics. Accordingly, the geographic areas of occurrence for weather-related hazards do not vary greatly across the Dubuque County, lowa 37 Multi-jurisdictional Hazard Mitigation Plan 2018 planning area for most hazards. The more urbanized areas within the planning area have more assets that are vulnerable to the weather-related hazards and varied development trends impact the future vulnerability. Similarly, more rural areas have more assets (crops/livestock) that are vulnerable to drought. These differences are discussed in greater detail in the vulnerability sections of each hazard. Although 19 hazards with the potential to significantly affect the planning area were identified and selected for additional analysis, not all hazards impact every jurisdiction. Table 3.4 provides a summary of the jurisdictions impacted by each hazard. An "x" indicates the jurisdiction is impacted by the hazard. A"N/A" indicates the hazard is not applicable to that jurisdiction. Table 3.4.

This prioritization was based on a hazard scoring system that considers four elements of risk: probability, magnitude/severity, warning time, and duration. Table 3.5 provides definitions for each of the four elements along with associated rating levels. Table 3.5. Hazard Score Element Definitions and Rating Scales ElemenUScore Definitions Probability: Refleds the likelihood of the hazard occurring again in the future, considering both the hazard's historical occurrence and the ro�eded likelihood of the hazard occurrin in an iven ear. 1—Unlikely Less than 10% probability in any given year(up to 1 in 10 chance of occurring), history of events is less than 10% likely or the event is unlikely but there is a possibility of its occurrence. 2—Occasional Between 10% and 20% probability in any given year(up to 1 in 5 chance of occurring), history of events is greater than 10% but less than 20% or the event could possibly occur. 3—Likely Between 20% and 33% probability in any given year(up to 1 in 3 chance of occurring), history of events is greater than 20% but less than 33% or the event is likely to occur. 4—Highly Likely More than 33% probability in any given year(event has up to a 1 in 1 chance of occurring), history of events is greater than 33% likely or the event is highly likely to occur. Magnitude/Severity: Assessment of severity in terms of injuries and fatalities, personal property, and infrastructure and the de ree and extent with which the hazard affects the �urisdiction. 1—Negligible Less than 10% of property severely damaged, shutdown of facilities and services for less than 24 hours, and/or injuries/illnesses treatable with first aid. 2—Limited 10% to 25% of property severely damaged, shutdown of facilities and services for more than a week, and/or injuries/illnesses that do not result in permanent disability. 3—Critical 25% to 50% of property severely damaged, shutdown of facilities and services for at least 2 weeks, and/or injuries/illnesses that result in permanent disability. 4—Catastrophic More than 50% of property severely damaged, shutdown of facilities and services for more than 30 days, and/or multiple deaths. Warning Time: Rating of the potential amount of warning time that is available before the hazard occurs. This should be taken as an avera e warnin time. 1 More than 24 hours warnin time 2 More than 12 to 24 hours warnin time 3 6 to 12 hours warnin time 4 Minimal or no warnin time u to 6 hours warnin Duration: A measure of the duration of time thatthe hazard will affect the �urisdiction. 1 Less than 6 hours 2 Less than 1 da 3 Lessthan1 week 4 More than one week Using the rating scales described in the table above, the formula used to determine each hazard's score, including weighting factors, is provided below: (Probability x .45) + (Magnitude/Severity x .30) +(Warning Time x .15) +(Duration x.10) = SCORE Dubuque County, lowa 3.9 Multi-jurisdictional Hazard Mitigation Plan 2018 Based on the hazard's overall weighted score, the hazards are categorized as follows: High (3.0-4.0), Moderate (2.0-2.9), and Low (1.0-1.9). These terms relate to the level of planning analysis to be given to the particular hazard in the risk assessment process and are not meant to suggest that a hazard would have only limited impact. In order to focus on the most critical hazards, those assigned a level of high or moderate were given more extensive attention in the remainder of the risk assessment (e.g., quantitative analysis or loss estimation), while those with a low planning significance were addressed in more general or qualitative ways. The HMPC determined overview hazard ranking scores for the planning area as a whole. The results of this overview are provided below in Table 3.6. Additionally, the hazard ranking overview is provided at the beginning of each hazard profile and vulnerability section. A detailed hazard summary by jurisdiction is provided at the conclusion of each hazard profile and vulnerability section to provide a summary of how the hazard varies by jurisdiction. Table 3.6.

In 2010, the lowa Climate Change Advisory Council reported to the Governor and the lowa General Assembly on Climate Change Impacts in lowa. The Report summarized the following climate changes lowa is already experiencing: Dubuque County, lowa 3.10 Multi-jurisdictional Hazard Mitigation Plan 2018 More Precipitation • Increased frequency of precipitation extremes that lead to flooding. • Increase of 8 percent more precipitation from 1873 to 2008. • A larger increase in precipitation in eastern lowa than in western lowa. Higher Temperatures • Long-term winter temperatures have increased six times more than summer temperatures. • Nighttime temperatures have increased more than daytime temperatures since 1970. • lowa's humidity has risen substantially, especially in summer, which now has 13 percent more atmospheric moisture than 35 years ago as indicated by a 3 - 5-degree F rise in dew- point temperature. This fuels convective thunderstorms that provide more summer precipitation. Agricultural Challenges • Climate extremes, not averages, have the greater impact on crop and livestock productivity. • Increased soil erosion and water runoff. • Increased challenges associated with manure applications. • Favorable conditions for survival and spread of many unwanted pests and pathogens. Habitat Changes • Plants are leafing out and flowering sooner. • Birds are arriving earlier in the spring. • Particular animals are now being sighted farther north than in the past. Public Health Effects • Increases in heart and lung programs from increasing air pollutants of ozone and fine particles enhanced by higher temperatures. • Increases in infectious diseases transmitted by insects that require a warmer, wetter climate. • An increase prevalence of asthma and allergies. Dubuque County, lowa 3.11 Multi-jurisdictional Hazard Mitigation Plan 2018 3.2 Assets at Risk This section assesses the population, structures, critical facilities and infrastructure, and other important assets in the planning area that may be at risk to hazards. 3.2.1 Total Exposure of Population and Structures 3.2.1 .1 Unincorporated County and Incorporated Cities Table 3.7 shows the total population and building / improvement counts and assessed values for the unincorporated county and each city in the planning area broken out by usage type. The methodology employed to extract the summary of building/improvement counts and values from the parcel data is provided below: • Parcel values that had an associated dwelling or improvement value were used as the structure file; • Parcel polygons were converted to points; and • Parcel points were spatially joined to the political area Qurisdiction). Population data is based on the U.S. Census Bureau's 2015 American Community Survey 5- year Estimates. Building counts and building exposure values are based on parcel data and assessed values provided by Dubuque County. The contents exposure values were calculated based on usage type. The contents multipliers were derived from the HAZUS and are defined below Table 3.7. Land values have been purposely excluded from the tables because land remains following disasters, and subsequent market devaluations are frequently short term and difficult to quantify. Additionally, state and federal disaster assistance programs generally do not address loss of land or its associated value (other than crop insurance).

This is important for the following reasons: • The plan participants may decide that these types of resources warrant a greater degree of protection due to their unique and irreplaceable nature and contribution to the overall economy. • If these resources are impacted by a disaster, knowing about them ahead of time allows for more prudent care in the immediate aftermath, when the potential for additional impacts is higher. • The rules for reconstruction, restoration, rehabilitation and/or replacement are often different for these types of designated resources. • Natural resources can have beneficial functions that reduce the impacts of natural hazards, such as wetlands and riparian habitat, which help absorb and attenuate floodwaters. • Losses to economic assets (e.g., major employers or primary economic sectors) could have severe impacts on a community and its ability to recover from disaster. In the planning area, specific assets include the following: Threatened and Endanqered Species: Table 3.11 includes Federally Threatened, Endangered, Proposed and Candidate Species in Dubuque County, lowa.

Land Use and Development The following sections provide details regarding future growth, land use and development. The information in this section comes from the Dubuque County 2013 Multi-jurisdictional Hazard Mitigation Plan, information provided by each of the participating jurisdictions as well as other sources, cited throughout. Where available, maps are provided to facilitate consideration of hazard areas in future development plans as well as potential growth area. Dubuque County The unincorporated areas of Dubuque County are primarily agricultural based. The topography varies through the County and associated land capabilities drive the type of farm-based enterprises that operate in a given location. Numerous major U.S. and state highways run through Dubuque County. Dubuque County has 17 townships and 21 incorporated cities, the most cities of any other county in lowa and is ranked the 7'h most populated county in lowa. There are 3 four-lane highways that provide access into the county: US Highway 20, US Highway 151 and US Highway 61 South. Additionally, there are two main two-lane highways that provide access into and around the county: US Highway 52 and lowa Highway 136 which is on the west end of the county. These five highways provide access to three-quarters of the cities in the County. The County's primary land use is agricultural and is found throughout the unincorporated areas of the county. Residential development in the county's unincorporated areas generally continues to occur according to previously established development patterns and is following the Future Land Use Development Map. Residential uses are primarily located near incorporated cities, along major highways and roadway corridors and are found in clusters up and down the Mississippi River. Most of the new residential growth continues to occur within 2- 4 miles of the City of Dubuque and near the larger cities in the county such as Cascade, Dyersville, Epworth, Farley, and Peosta. Commercial development is located mostly along the highway corridors with most of the commercial uses found along US Highways 151 and 61 south from the City of Dubuque to the Airport, along US Highway 20 from the Dubuque City limits to Peosta and along US Highway 52 from the City of Dubuque to Mud Lake Road. Some new commercial development is occurring in the flood plain along the Couler Valley and Little Maquoketa River north of the City of Dubuque. Property owners are filling in the old barrow pits along Highway 52 North that are in the flood plain and then marketing the property for new commercial and industrial uses. The County is looking into amending the Flood Plain Management Ordinance to restrict the filling in of flood plain and to reduce the occurrence of flooding in that area and in the County, as a whole. Industrial uses in Dubuque County are primarily located in three areas around the City of Dubuque. The first area is to the south along Highways 52, 151 and 61. New development is occurring in Tamarak Park and near the airport. Another industrial area is located west of the City of Dubuque along Highway 20. This area is mostly developed from the Dubuque city limits to Peosta. The third area is along Highway 52 North in the Couler Valley and Little Maquoketa Dubuque County, lowa 3.30 Multi-jurisdictional Hazard Mitigation Plan 2018 River outlet to the Mississippi River. John Deere Dubuque is located just outside the flood plain of the Little Maquoketa River. Over the last few years, Flood Plain Permits have been issued for filling in the flood plain along Highway 52 North. Some older more established businesses are seeing flooding in the Couler Valley watershed that have not flooded before. New development will occur along this corridor until the Flood Plain Management Ordinance is amended to restrict filling in and development of the flood plain in this area. Both the South and West commercial and industrial corridors will be affected by the proposed four-lane highway, the Southwest Arterial that will be built in the next 5-10 years between US Highways 151/61 and US Highway 20. Residential, commercial and industrial development is expected to occur from the city limits on the southwest side of the City of Dubuque to beyond the Southwest Arterial after the new highway is built. This change in land use will be put into the Future Land Use Development Map at some future date as construction of the highway is nearing completion. Dubuque County's Comprehensive Land Use Development Plan and Map is the community's guide to future development of the unincorporated areas of Dubuque County. The development plan and map guide development decisions made by the Board of Supervisors. The Comprehensive Land Use Development Plan is not an ordinance. It contains the long-range goals and objectives for the County that was compiled after several public meetings and hearings to determine a community vision for the future of Dubuque County. The first Comprehensive Plan for the County was adopted on January 21, 1969 and was recently updated in 2011-2012 to incorporate the 10 Smart Planning Principles and 13 Comprehensive Planning Elements adopted by the State of lowa.

Dubuque County, lowa 3.33 Multi-jurisdictional Hazard Mitigation Plan 2018 3.5 Hazard Profiles and Vulnerability Hazard Profiles Requirement §201.6(c)(2)(i): [The risk assessment shall include a] description of the...location and extent of all natural hazards that can affect the jurisdiction. The plan shall include information on previous occurrences of hazard events and on the probability of future hazard events. Each hazard identified in Section 3.1.4 is profiled individually in this section in alphabetical order. The level of information presented in the profiles varies by hazard based on the information available. With each update of this plan, new information will be incorporated to provide for better evaluation and prioritization of the hazards that affect the planning area. Detailed profiles for each of the identified hazards include information categorized as follows: Hazard Description This section consists of a general description of the hazard and the types of impacts it may have on a community. It also includes the ratings assigned to the hazard relative to typical warning times and duration of hazard events as described in Table 3.5. Geographic Location/Extent This section describes the geographic location of the hazard in the planning area. Where available, maps are utilized to indicate the specific locations of the planning area that are vulnerable to the subject hazard. This section also provides information as to the extent of the hazard (i.e. the size or degree of impacts). Previous Occurrences This section includes information on historic incidents and their impacts. Probability of Future Occurrence The frequency of past events is used to gauge the likelihood of future occurrences. Where possible, the probability or chance of occurrence was calculated based on historical data. Probability was determined by dividing the number of events observed by the number of years and multiplying by 100. This gives the percent chance of the event happening in any given year. An example would be three droughts occurring over a 30-year period, which suggests a 10 percent chance of a drought occurring in any given year. For each hazard, the probability is assigned a rating as defined in Table 3.5. Dubuque County, lowa 3.34 Multi-jurisdictional Hazard Mitigation Plan 2018 Vulnerabilitv Assessments Requirement §201.6(c)(2)(ii): [The risk assessment shall include a] description of the jurisdiction's vulnerability to the hazards described in paragraph (c)(2)(i) of this section. This description shall include an overall summary of each hazard and its impact on the community. Requirement §201.6(c)(2)(ii)(A): The plan should describe vulnerability in terms of the types and numbers of existing and future buildings, infrastructure, and critical facilities located in the identified hazard areas. Requirement §201.6(c)(2)(ii)(B): [The plan should describe vulnerability in terms of an] estimate of the potential dollar losses to vulnerable structures identified in paragraph (c)(2)(i)(A) of this section and a description of the methodology used to prepare the estimate. Requirement §201.6(c)(2)(ii)(C): [The plan should describe vulnerability in terms ot] providing a general description of land uses and development trends within the community so that mitigation options can be considered in future land use decisions. Requirement §201.6(c)(2)(ii): (As of October 1, 2008) [The risk assessment] must also address National Flood Insurance Program (NFIP) insured structures that have been repetitively damaged in floods. Following the hazard profile for each hazard is the vulnerability assessment. The vulnerability assessment further defines and quantifies populations, buildings, critical facilities and other community assets at risk to natural hazards. The vulnerability assessments were conducted based on the best available data and the significance of the hazard. Data to support the vulnerability assessments was collected from the following sources: • Available GIS data sets such as DFIRM, parcel data, critical facilities, etc. (all sourced when used); • Homeland Security Infrastructure Program Freedom, 2015; • Written descriptions of assets and risks provided by participating jurisdictions; • Existing plans and reports; • Personal interviews with planning committee members and other stakeholders; and • Other sources as cited. Detailed profiles for each of the identified hazards include information categorized as follows: Vulnerability Overview This section consists of a general overview narrative of the planning area's vulnerability to the hazard. Within this section, the magnitude/severity of the hazard is discussed. The magnitude of the impact of a hazard event (past and perceived) is related directly to the vulnerability of the people, property and the environment it affects. This is a function of when the event occurs, the Dubuque County, lowa 3.35 Multi-jurisdictional Hazard Mitigation Plan 2018 location affected, the resilience of the community and the effectiveness of the emergency response and disaster recovery efforts. For each hazard, the magnitude/severity is assigned a rating as defined in Table 3.5. Potential Losses to Existing Development This section provides the potential losses to existing development. Where data is available, this section provides estimated financial losses as well as the methodology used. For hazards with an overall "LovJ' rating, potential losses may not be discussed. Future Development This section provides information on how vulnerability to this hazard will be impacted by planned future development, as well as information for jurisdictions to consider in planning future development. Climate Change Impacts This section will discuss any potential impacts to this hazard as a result of climate change. Hazard Summary by Jurisdiction For hazards that vary by jurisdiction, this section will provide an overview of how the hazard varies, followed by a table indicating the probability, magnitude, warning time and duration rankings for each jurisdiction with the resulting hazard score and level. Dubuque County, lowa 3.36 Multi-jurisdictional Hazard Mitigation Plan 2018 3.5.1 Animal/Plant/Crop Disease Hazard Score Calculation Probabilit Ma nitude/Severit Warnin Time Duration Wei hted Score Level 1 4 4 4 2.65 Moderate Profile Hazard Description Agricultural infestation is the naturally occurring infection of vegetation, crops or livestock with insects, vermin, or diseases that render the crops or livestock unfit for consumption or use. Because of lowa's overall substantial agricultural industry and related facilities and locations, the potential for infestation of crops or livestock poses a significant risk to the economy of the State. lowa cropland is vulnerable to disease and other agricultural pests. Some level of agricultural infestation is normal in lowa. The concern is when the level of an infestation escalates suddenly, or a new infestation appears, overwhelming normal control efforts. The levels and types of agricultural infestation appear to vary by many factors, including cycles of heavy rains and drought. Animal Disease Agricultural incidents are naturally occurring infection of livestock with insects, vermin, or diseases that render the livestock unfit for consumption or use. The livestock inventory for the state of lowa includes nearly 4 million cattle and calves. According to the USDA National Agricultural Statics Service, as of January 1, 2015, Dubuaue Countv ranked 3'' in the state with 135,000 head of cattle and calves. According to the 2012 Census of Agriculture, there were also 137,271 head of hoqs and piqs in Dubuque Countv. With this substantial agricultural industry and related facilities throughout the State, the potential for infestation of livestock poses a significant risk to the lowa economy. The lowa Department of Agriculture and Land Stewardship (IDALS) monitors and reports on the following animal reportable diseases in lowa: • Avian Influenza • Bovine Spongiform Encephalopathy (BSE) Disease • Chronic Wasting Disease • Exotic Newcastle Disease • Foot and Mouth Disease • Johne's Disease • Pseudo rabies • Scrapie, and • West Nile Virus. Dubuque County, lowa 3.37 Multi-jurisdictional Hazard Mitigation Plan 2018 Producers are required by state law to report any of the reportable animal diseases to the IDALS's Bureau of Animal Industry. The IDALS's Bureau of The Center for Agriculture Security is the lead coordinating bureau for any emergency response for an agriculture incident. Avian influenza continues to be of concern in lowa as the State is number one in poultry egg layers (approximately 40 million). Source: lowa Poultry Association, 2014. Bovine Spongiform Encephalopathy (BSE) "mad covJ' disease is a chronic, degenerative disease affecting the central nervous system of cattle. Cases have been found world-wide since 1986, but in Canada and the U.S. only a single cow was reported with BSE in 2003. Chronic Wasting Disease (CWD) is a fatal, neurological disease of farmed and wild deer and elk. The disease has been identified in wild and captive mule deer, white-tailed deer and North American elk, and in captive black-tailed deer. The first case of CWD in lowa was found in 2012 on a hunting preserve in the southeastern part of the State. Exotic Newcastle disease (END) is a contagious and fatal viral disease affecting all species of birds. There was an epidemic of END in California in 2003 that is resulting in the death of millions of chickens and other birds, and costing millions of dollars. END is probably one of the most infectious diseases of poultry in the world. END is so virulent that many birds die without showing any clinical signs. Johne's (yo-knees) disease is a contagious, chronic and eventually fatal infection that affects the small intestine of ruminants, including cattle, sheep and goats. Johne's, also called Para tuberculosis, is a slow progressive wasting disease with an incubation period of usually 2 or more years. Johne's is a reportable disease, but not a quarantinable disease. Pseudo rabies is a viral disease most prevalent in swine, often causing newborn piglets to die. Older pigs can survive infection, becoming carriers of the pseudo rabies virus for life. Other animals infected from swine die from pseudo rabies, which is also known as Aujeszky's disease and "mad itch." Infected cattle and sheep can first show signs of pseudo rabies by scratching and biting themselves. In dogs and cats, pseudo rabies can cause sudden death. The virus does not cause illness in humans. Due to an extensive eradication program, lowa and the rest of United States are free of pseudo rabies. Scrapie is a fatal, degenerative disease affecting the central nervous system of sheep and goats that is very similar to BSE (mad cow disease), although it does not cause disease in humans, and has been present in the U.S. for over 50 years. Infected flocks that contain a high percentage of susceptible animals can experience significant production losses. In these flocks, over a period of several years, the number of infected animals increases and the age at onset of clinical signs decreases making these flocks economically unviable. Animals sold from infected flocks spread scrapie to other flocks. The presence of scrapie in the U.S. also prevents the export of breeding stock, semen and embryos to many other countries. Currently there is a national program underway to eradicate scrapie in the U.S. Disease outbreaks can also occur in wild animal populations. The IDALS's Bureau of Animal Industry also monitors wild animal species and game throughout the state as well as diseases that may impact them. Dubuque County, lowa 3.38 Multi-jurisdictional Hazard Mitigation Plan 2018 Crop Pests/Diseases A plant disease outbreak or a pest infestation could negatively impact crop production and agriculturally dependent businesses. An extreme outbreak or infestation could potentially result in billions of dollars in production losses across the U.S. The cascading net negative economic effects could result in wide-spread business failures, reduction of tax revenues, harm to other state economies, and diminished capability for this country to compete in the global market. Many factors influence disease development in plants, including hybrid/variety genetics, plant growth stage at the time of infection, weather (e.g., temperature, rain, wind, hail, etc.), single versus mixed infections, and genetics of the pathogen populations. The two elements of coordination and communication are essential when plant diseases or pest infestations occur. The United States Department of Agriculture/ Animal Plant Health Inspection Service, lowa Department of Agriculture and Land Stewardship, local producers, local government, assessment teams and state government entities must work together to effectively diagnose the various plant hazards to determine if immediate crop quarantine and destruction is required. lowa State University, College of Agriculture and Life Sciences, has The Plant and Insect Diagnostic Clinic http://www.ipm.iastate.edu/ipm/info/insects that provides diagnosis of plant problems (plant diseases, insect damage, and assessment of herbicide damage) and the identification of insects and weeds from the field, garden, and home. Specific plant pests can vary from year to year. For complete details of all insects and diseases that can impact crops in Dubuque County, see the website above. Emerald Ash Borer The Hazard Mitigation Planning Team is also aware of the emerald ash borer pest that threatens lowa's forests and urban landscape. This pest is a slender, emerald green beetle that is Y inch long, and responsible for the destruction of approximately 20 million ash trees in Ohio, Michigan, Indiana, Illinois, and Ontario, Canada. Emerald Ash Borer has made its way into lowa and has become an increasing threat. Wildlife lowa farmers lose a significant amount of crops each year as a result of wildlife foraging. This can be particularly problematic in areas where natural habitat has been diminished or in years where weather patterns such as early/late frost deep snow, or drought has caused the wild food sources to be limited. Warninq Time Score: 4—minimal or no warning time Duration Score: 4—more than 1 week Geographic Location/6ctent All of Dubuque County is subject to animal/livestock incidents and agricultural infestations. According to the 2012 Census of Agriculture there were 1,462 farms in the County covering 291,441 acres of land (74.9 percent of the 608 Sq. miles of land area (389,120 acres) in the County). There were 1,462 farms with an average size of 199 acres per farm.

Previous Occurrences Beginning in April of 2015, there were a significant number of confirmed diagnoses of avian influenza in the State of lowa. As a result, on Friday May 1, 2015, Governor Branstad declared a state of emergency. The last positive flock was detected on June 16, 2015. Confirmed cases occurred in the following counties: Buena Vista, Calhoun, Cherokee, Clay, Hamilton, Kossuth, Lyon, Madison, O'Brien, Osceola, Palo Alto, Plymouth, Pocahontas, Sac, Sioux, Webster, and Dubuque County, lowa 3.44 Multi-jurisdictional Hazard Mitigation Plan 2018 Wright. Infected flocks were depopulated and composted and clean up and disinfection occurred. There were 77 total premises and 34 million birds affected. This included 35 commercial turkey flocks, 22 commercial egg production flocks, 13 pullet flocks, 1 breeding flock for a mail order hatchery, and 6 backyard flocks. More than 2,300 USDA staff and contractors were dispatched to lowa to assist with the response to the avian influenza situation, including a USDA Incident Management Team (IMT). More than 300 state employees also participated in the disaster response (http://vwvw.iowaaqriculture.qov/Avianlnfluenza.asp). There were no reported infected flocks in Dubuque County. Bovine Sponqiform Encephalopathv (BSE) (A.K.A. Mad Cow Disease) To date, BSE has been confirmed in Great Britain, Belgium, France, Germany, Spain, Switzerland, Japan, Canada, and the United States. In the United States, the first positive BSE cow was discovered in Washington. As a result of a surveillance program from June 2004 to March 2006, two additional positive domestic cows were found; one each in Texas and Alabama. Since 1997 FDA implemented a feed ban prohibiting the feeding of feedstuff derived from ruminants to other ruminants. The results of this ban and enhanced surveillance indicate that while BSE is present, it is at an extremely low level in U.S. cattle. Chronic Wastinq Disease The first case of CWD in lowa was found in 2012 on a hunting preserve in the southeastern part of the state. In that case, it was determined the CWD-positive mature buck had been transferred to the hunting preserve from a deer farm in north central lowa. Subsequent testing found CWD at the deer farm. The farm was placed under quarantine, but the owners sued for compensation. The litigation prevented the farm from being depopulated of deer until August 2014. The lowa Department of Agriculture and Land Stewardship conducted testing. Results were released in early October 2014, stating that 284 of 356 deer (80 percent) from a captive herd in north-central lowa tested positive for chronic wasting disease. This finding represents the highest number of CWD-positive animals detected at a facility, according to wildlife health officials (Milwaukee-Wisconsin Journal Sentinel, October 4, 2014). In 2014, the first case of CWD was found in a wild deer in Allamakee County. Then in 2015, two wild deer tested positive for CWD in Allamakee County. Scrapie There has been a total of 37 sheep flocks in lowa that have been found to be infected with Scrapie since the accelerated national Scrapie Eradication Program started in November 2001. Of those, 10 have been depopulated and 27 have completed, or are currently completing a genetic flock plan. lowa's last infected flock was found in June 2010. Rabies According to the lowa Department of Public Health, Center for Acute Disease Epidemiology, there were12 confirmed animal rabies cases in lowa in 2015. In 2014, there were 15. In 2013, there were 12. In 2012, there were 31 and in 2011 there were 25. In 2016, there were 16 confirmed cases in the state. Dubuque County, lowa 3.45 Multi-jurisdictional Hazard Mitigation Plan 2018 Table 3.19 summarizes the occurrence of rabies in Dubuque County from 2011-2016. Table 3.19.

The concern is when the level of an infestation escalates suddenly, or a new infestation appears, overwhelming normal control efforts. Normal control efforts include crop insurance and employment of various other agricultural practices that limit impact. For purposes of determining probability of future occurrence, the HMPC defined "occurrence" as an infestation occurring suddenly, a new infestation, or infestation that overwhelmed normal control efforts. Research did not reveal any infestations in Dubuque County that have reached this level of defined "occurrence". Therefore, it was determined that the probability of this defined "occurrence" of agricultural infestation is "Unlikely". Probabilitv Score: 1—Unlikely Dubuque County, lowa 3.46 Multi-jurisdictional Hazard Mitigation Plan 2018 Vulnerabilitv Overview A widespread infestation of animals/livestock and crops could impact the economic base of the County. According to the USDA 2012 Census of Agriculture, Dubuque County agriculture provides 69,694 jobs representing 7.3 percent of Dubuque County's total workforce (Source: Coalition to Support lowa's Farmers, http://www.supporffarmers.com/Assets/2014/cntvdata/Dubuque.pdfl. In 2012 the total market value of Dubuque County's agricultural products sold was $387,810,000. With this contribution of agriculture to the economy, a wide-scale agricultural infestation could severely impact the economic stability of the County. Maqnitude Score: 4—Catastrophic Potential Losses to E�cisting Development Buildings, infrastructure, and critical facilities are not vulnerable to this hazard. Its impacts are primarily economic and environmental, rather than structural effects. Rough estimates of potential direct losses from a maximum threat event fall in a range of 1-75 percent of livestock receipts. The market value of all livestock in Dubuque County in 2012 was $267,757,000. Based on a worst-case scenario where 75 percent of livestock is lost in a given year due to agricultural infestations, the total direct costs could exceed $200 million. Table 3.21 provides the annual crop losses for insurable crops. The insurable loss is adjusted to estimate losses to all insurable crops by considering that 89 percent of insurable crops in the State were insured (2015 lowa Crop Insurance Profile from USDA's Risk Management Agency). Table 3.21. Estimated Insurable Crop Losses Resulting from Disease, Infestation, and Wildlife Annual Crop Insurance Adjusted 10-year Estimated Paid-10 yrs. Losses Losses $214,307 $240,794 $24,079 Source: USDA Risk Management Agency; adjust loss calculation by Amec Foster Wheeler Rough estimates of potential direct losses from a maximum threat event fall in a range of 1-50 percent of annual crop receipts. The market value of all crops sold in Dubuque County in 2012 was $120,053,000. Based on a worst-case scenario where 50 percent of crop production is lost in a given year due to agricultural infestations, the total direct costs could exceed $60 million. The U.S. Forest Service estimates that Dubuque County has up to 500,000 ash trees in the County. Removal of debris if an infestation would occur would be challenging and costly. If only 10 percent of the Ash trees were impacted in Dubuque County that could translate to 50,000. It is estimated that it costs $682 to replace each Ash tree. In Dubuque County, this translates to over $34 million Dubuque County, lowa 3.47 Multi-jurisdictional Hazard Mitigation Plan 2018 Future Development Future development is not expected to significantly impact the planning area's vulnerability to this hazard. However, if crop production and numbers of animals/livestock increases, the amount vulnerable to infestation also increases. Regarding the Emerald Ash Borer, the lowa Department of Natural Resources recommends that other native tree species be planted in lieu of Ash trees to avoid increasing vulnerability to infestation of the Emerald Ash Borer. Climate Change lmpacts The climate change impacts below are excerpted from the 2010 Report on Climate Change lmpacts on lowa developed by the lowa Climate Change Impacts Committee CrOpS Despite great improvements in yield potential over the last several years, crop production remains highly dependent on climate in conjunction with other variables. The overall effect of climate change on crop productivity in lowa remains unclear, as positive climatic events could be overridden by the impacts of poor management or genetics, or favorable management and genetics could override negative climate events. Regardless of these interactions, it is certain that climate changes will affect future crop production. Greenhouse and growth chamber studies suggest increases in atmospheric carbon dioxide (CO2) will generally have a substantial positive effect on crop yields by increasing plant photosynthesis and biomass accumulation. Greater precipitation during the growing season, as we have been experiencing in lowa, has been associated with increased yields; however, excessive precipitation early in the growing season adversely affects crop productivity. Waterlogged soil conditions during early plant growth often result in shallower root systems that are more prone to diseases, nutrient deficiencies and drought stress later in the season. An increase in temperature, especially during nighttime, reduces corn yield by shortening the time in which grain is accumulating dry matter (the grain fill period). According to research, lowa's nighttime temperatures have been increasing more rapidly than daytime temperatures. The current changes in precipitation, temperature, wind speeds, solar radiation, dew-point temperatures, and cloud cover imply less ventilation of crops and longer dew periods. Soybean plants in particular readily absorb moisture, making harvest problematic. One adaptive approach to these conditions involves farmers purchasing larger harvesting equipment to speed harvest, compensating for the reduced daily time suitable for soybean harvest. The recent extreme weather events involving greater intensity and amount of rainfall have increased the erosive power of lowa's precipitation, resulting in significant erosion of topsoil. The impact of climate change on the erosive force of precipitation in the U.S. is expected to increase by as much as 58%. These rates are expected to increase exponentially as precipitation continues to rise. Plant disease can also increase as temperature, soil wetness, and humidity increase as these conditions favor the development of various plant diseases. Dubuque County, lowa 3.48 Multi-jurisdictional Hazard Mitigation Plan 2018 Animals Despite the fact that lowa ranks first in hog and fifth in cattle production nationwide, there is a lack of information about the effects of climate change on animal production in lowa. Nevertheless, our general knowledge and principles pertaining to livestock and extreme weather events are applicable to lowa's changing climate conditions. High temperatures have been shown to reduce summer milk production, impair immunological and digestive functions of animals, and increase mortality rates among dairy cattle. In general, domestic livestock can adapt to gradual changes in environmental conditions; however, extended periods of exposure to extreme conditions greatly reduce productivity and is potentially life threatening. Animal/Crop/Plant Disease Hazard Summary by Jurisdiction The magnitude determinations discussed in the vulnerability overview sections were factored into the following hazard summary table to show how this hazard varies by jurisdiction. It has been determined that the magnitude of animal/crop/plant disease would be slightly less in the cities and for the school districts due to less agriculture within city limits. However, an infestation of the Emerald Ash Borer would likely have a larger impact in the incorporated areas and the economy of incorporated areas is heavily dependent on agriculture. As a result, the magnitude in the unincorporated area was determined to be a 4 and the magnitude in the incorporated areas was determined to be a 3. School districts would have limited Ash trees to dispose of in the event of infestation. Therefore, the magnitude was determined to be a 1.

OFten, these streams or rivers later needed a dam or levee for flood control or a reservoir for a constant water source. This section discusses both dam and levee failure. Dam Failure A dam is defined as a barrier constructed across a watercourse for the purpose of storage, control, or diversion of water. Dams are typically constructed of earth, rock, concrete, or mine tailings. Dam failure is the uncontrolled release of impounded water resulting in downstream flooding, affecting both life and property. Dam failure can be caused by any of the following: flooding; earthquakes; flow blockages; landslides; lack of maintenance; improper operation; poor construction; vandalism; or terrorism. Levee Failure Levee Failure is the uncontrolled release of water resulting from a structural failure. Possible causes of the failure could include flooding, earthquakes, blockages, landslides, lack of maintenance, improper operation, poor construction, vandalism, terrorism, erosion, piping, saturation, or under seepage. Warninq Time Score: 4—Minimal or no warning (up to 6 hrs. warning) Duration Score: 4—More than 1 week Geographic Location/6ctent Dams in Planninq Area The thresholds for when a dam falls under State regulation are outlined in lowa Administrative Code 567-71.3 and are listed below. The thresholds are primarily based on both dam height and water storage volumes. State regulated dams are those dams that meet the following: In rural areas: a. Any dam designed to provide a sum of permanent and temporary storage exceeding 50 acre-feet at the top of dam elevation, or 25 acre-feet if the dam does not have an emergency spillway, and which has a height of 5 feet or more. b. Any dam designed to provide permanent storage in excess of 18 acre-feet and which has a height of 5 feet or more. c. Any dam across a stream draining more than 10 square miles. Dubuque County, lowa 3.50 Multi-jurisdictional Hazard Mitigation Plan 2018 d. Any dam located within 1 mile of an incorporated municipality, if the dam has a height of 10 feet or more, stores 10 acre-feet or more at the top of dam elevation, and is situated such that the discharge from the dam will flow through the incorporated area. In urban areas: Any dam which exceeds the thresholds in 71.3 (1) "a", "b", or"d". Low head dams: Any low head dam on a stream draining 2 or more square miles in an urban area, or 10 or more square miles in a rural area. Dams are classified by the State of lowa into three categories based on the potential risk to people and property in the event of failure (see Table 3.22). The classification can change over time due to changes in development downstream from the dam. In addition, older dams may not have been built to the standards of their updated classification when this occurs. The lowa Department of Natural Resources performs annual inspections on all high hazard dams in the State. Table 3.22. Dam Hazard Classification Definitions Hazard Class Definition High A structure shall be classified as high hazard if located in an area where failure may create a serious threat of loss of human life or result in serious damage to residential, industrial, or commercial areas, important public utilities, public buildings, or major transportation facilities. Moderate A structure shall be classified as moderate hazard if located in an area where failure may damage (Significant)* isolated homes or cabins, industrial or commercial buildings, moderately traveled roads or railroads, interrupt major utility services, but without substantial risk of loss of human life. In addition, structures where the dam and its impoundment are of themselves of public importance, such as dams associated with public water supply systems, industrial water supply or public recreation, or which are an integral feature of a private development complex, shall be considered moderate hazard for design and regulatory purposes unless a higher hazard class is warranted by downstream conditions. Low A structure shall be classified as low hazard if located in an area where damages from a failure would be limited to loss of the dam, loss of livestock, damages to farm outbuildings, agricultural lands, and lesser used roads, and where loss of human live is considered unlikely. Source: lowa Department of Natural Resources; '4he term"moderete"is used by the lowa Department of Natural Resources. However,the National Inventory of Dams uses the term "significanP'to identifythe same general hazard classification For this plan update, both the National Inventory of Dams as well as the State-regulated dam inventory were consulted. There are 13 regulated dams inside the county boundaries of Dubuque County. Of the 13 dams, two are High Hazard dams, four are Significant Hazard dams, and seven are Low Hazard dams. One of the high hazard dams is a federal dam; the Mississippi River Lock & Dam No. 11, which is owned and operated by the U.S. Army Corps of Engineers.

NationallnventoryofDams Dams Upstream of Planninq Area The planning committee expressed concern regarding Lake Delhi dam. This upstream dam in Delaware County on the Maquoketa failed during flooding in 2010 and was rebuilt in 2016. Levees in Planninq Area The National Levee Database and the FEMA Flood Insurance Rate Map were consulted to identify levees in the planning area. There are two levee segments in Dubuque County as follows: • Dubuque Levee-5.5 miles long. This Corps Program levee was construded in 1973 by the USACE and then turned over to the sponsors for operations and maintenance. The sponsors are the City of Dubuque and the Royal Oaks Development Corporation. It received an "Acceptable" Inspedion rating by USACE in November 2014. The levee protects almost all of the City of Dubuque from Mississippi River flooding to an elevation of 615.47 msl (nver state 30.0"). Only Dubuque's Chaplain Schmitt Island and Caffish Creek valley lie outside the protection of Dubuque's floodwall levee. The levee has withstood river crests as high as 611.93 msl (nver state 26.46'). FEMA certified Dubuque's floodwall and levee system in 2011. Dubuque County, lowa 3S5 Mulfi junsdicfional HazaN Mitigation Plan 2018 • Cascade Levee-0.96 miles long. This Corps Program levee was locally constructed and is locally operated and maintained by the City of Cascade. It received an "Acceptable" Inspection rating by USACE in May 2015. The North Fork of the Maquoketa River flows through the City of Cascade between Filmor and Pierce Streets. Several small ephemeral streams flow through the community into the North Fork of the Maquoketa River. In 1925, the City of Cascade experienced a catastrophic and unprecedented flood following cloudbursts. Property damage was estimated at $500,000. The area that received the most damage is located southward along Johnson Street. As a result, Upstream of the US Highway 151 Bridge, levees were constructed on both banks; downstream of the bridge, a levee was built only on the west bank since the east bank was sufficiently high. Portions of the levee have been sandbagged during high-flow conditions. The levee on the west bank of the river, upstream of the bridge, is responsible for protecting the highly developed daddle-like area that was damaged in the 1925 flood. In April 1990, the Rock Island District COE inspected and evaluated the existing condition of the city's flood-control project under Public Law 84-99. Based upon the results of the field inspection and the evaluation, the overall condition of the levee in the City of Cascade was rated unacceptable. The levee crown was rated at approximately a 10-year frequency. Based on the 1990 COE inspection and evaluation, the City of Cascade completed two installments of levees. In 1999-2000, the City constructed a levee on the south portion of the west bank of the river and the second portion was installed in fall 2011. The Corps of Engineers inspects annually and makes recommendations; however, the second extension has not yet been tested as there have been no heavy rains since it was constructed. This portion of the levee was locally funded. In 2009, rip rap and rocks were put in to stabilize the north side of the western back bank as well. The bank on the north end is not completely rip-rapped and is only an earthen levee due to funding. Downstream from the bend in the North Fork of the Maquoketa River is rip-rapped, which is where the force of the water is greatest.

No record of dam failure within Dubuque County boundaries was found. Levee Failure No events of levee failure in Dubuque have occurred since completion of its 64-mile-long earthen and concrete levee in 1973. Probability of Future Occurrence The flooding of 1993 and again in 2008 was so great that the limits of many levees were tested and sometimes exceeded. Of the 275 Corps of Engineers levees affected by the 1993 flood, Dubuque County, lowa 3.59 Multi-jurisdictional Hazard Mitigation Plan 2018 85% held, of the 15%that failed, 31 overtopped (11%), eight (8) eroded and ruptured (3%), and three (3) breached (1%). The performance of non-federal levees was much worse: only 43% withstood the trauma, and 800 of 1,400 failed. The rate of failure of a levee or floodwall is difficult to predict with sudden failure a possibility. Both the Corps of Engineers and City of Dubuque Engineers agree that "overtopping" of the Dubuque levee is a more likely scenario than levee failure. Probabilitv Score: 2-0ccasional, between 10 percent and 20 percent probability in any given year. Vulnerabilitv Overview Dam Failure Dam or levee failure is typically an additional or secondary impact of another disaster such as flooding or earthquake.

The Carter Road Stormwater Detention Dam 2016 Inspection from the Department of Natural Resources resulted in rating of"Satisfactory" This means that no existing dam safety deficiencies are recognized for normal loading conditions. However, infrequent hydrologic and/or seismic events would probably result in a dam safety deficiency. The High Hazard federal dam is routinely inspected by the Corps of Engineers. Levee Failure The Corps of Engineers conducts two types of levee inspections as part of the Levee Safety Program: • Routine Inspections, also called annual inspections or continuing eligibility inspections, are visual inspections that verify proper levee system operation and maintenance. Routine Inspections are conducted on an annual basis. • Periodic Inspections provide a more rigorous assessment than the Routine Inspection and include a more detailed and consistent evaluation of the condition of the levee system. Periodic Inspections verify proper operation and maintenance; evaluate operational adequacy, structural stability and safety of the system; and compare current design and construction criteria with those in place when the levee was built. Periodic Inspections are conducted every five years. Inspection results of acceptable, minimally acceptable or unacceptable are provided to project sponsors to address deficiencies. Additionally, the District will work with sponsors to identify performance concerns, areas for further analysis, changes in design criteria and potential consequences of levee failures that need to be addressed in order to provide the continued safety of the levee. Both the Dubuque (2014) and Cascade (2015) Levees received "Acceptable" ratings from their most recent inspections. A magnitude rating of "catastrophic" is appropriate due to the potential for the loss of life from failure of the high hazard dam or the levees. Maqnitude/Severitv Score: 4—Catastrophic Potential Losses to E�cisting Development The jurisdictions that would be impacted in the event of failure of the high or significant hazard dams or levees are discussed below relative to the applicable flood protection structure: • Carter Road Stormwater Detention Dam, High Hazard—City of Dubuque (0 miles) • Mississippi River Lock & Dam No. 11, High Hazard�ity of Dubuque (1 mile) • Seippel Road Dam, Significant Hazard—City of Dubuque (0 miles) • Southeast Dam (Dubuque), Significant Hazard—City of Dubuque (0 miles) • West 32nd St Stormwater - Lower Dam, Significant Hazard—City of Dubuque (0 miles) • West 32nd St Stormwater - Upper Dam, Significant Hazard—City of Dubuque (0 miles) • Dubuque Levee�ity of Dubuque • Cascade Levee—City of Cascade Dubuque County, lowa 3.61 Multi-jurisdictional Hazard Mitigation Plan 2018 Dam Failure Based on the definition of high hazard dams, failure of these dams could create a serious threat of loss of human life or result in serious damage to residential, industrial, or commercial areas, important public utilities, public buildings, or major transportation facilities. For the significant hazard dams, failure could result in damage to isolated homes or cabins, industrial or commercial buildings, moderately traveled roads or railroads, or interrupt major utility services, but without substantial risk of loss of human life. Inundation maps were provided by the lowa DNR for Carter Road Stormwater Detention Dam. Inundation maps were not available for other dams in the planning area. Combined with the parcel data in a GIS format with assessed values, the inundation map allowed comparative analysis of this layer to determine parcels and improvement values by type that fall within the boundaries of the dam inundation area. GIS was used to create a centroid or point representing the center of the parcel polygon. The dam inundation area was then overlaid on the parcel centroids. For the purposes of this analysis, if the dam inundation area intersected a parcel centroid, inundation was assigned for the entire parcel. The model assumes that every parcel with a building or dwelling value greater than zero is improved in some way. Specifically, an improved parcel assumes there is a building on it. It is important to note that there could be more than one structure or building on an improved parcel (i.e. condo complex occupies one parcel but might have several structures). In these cases, the analysis counts this as one structure. Only improved parcels and the value of their improvements were analyzed. The end result is an inventory of the number and types of parcels and buildings subject to dam failure. Table 3.24 provides the numbers of improved parcels (structures), and values by type of parcel that are in the dam inundation area according to the analysis methodology described above. Table 3.24.

To determine the potential number of people that might be impacted by failure of the Carter Road Stormwater Detention Dam, the average household size from the 2010 U.S. Census (2.28) was multiplied by the number of dwellings (residential structures) in the dam inundation areas (653). This revealed approximately 1,489 people at risk to failure of this dam. This Dubuque County, lowa 3.62 Multi-jurisdictional Hazard Mitigation Plan 2018 analysis is limited due to the uncertainty of how many separate households are in the multi- residential structures. Levee Failure GIS data was available from the National Levee Inventory to identify the levee protected areas for both the Cascade Levee and the Dubuque FCW Levee. Combined with the parcel data in a GIS format with assessed values, this allowed comparative analysis of these two layers to determine parcels and improvement values by type that fall within the boundaries of the levee protected areas. GIS was used to create a centroid or point representing the center of the parcel polygon. The levee protected areas were then overlaid on the parcel centroids. For the purposes of this analysis, if the levee protected area intersected a parcel centroid, the levee protection area (and thus the area prone to failure) was assigned for the entire parcel. The model assumes that every parcel with a building or dwelling value greater than zero is improved in some way. Specifically, an improved parcel assumes there is a building on it. It is important to note that there could be more than one structure or building on an improved parcel (i.e. condo complex occupies one parcel but might have several structures). In these cases, the analysis counts this as one structure. Only improved parcels and the value of their improvements were analyzed. The end result is an inventory of the number and types of parcels and buildings subject to levee failure.

According to this analysis, there is nearly$8 million in improvements / contents value in the area protected by the Cascade Levee and nearly $1 billion in improvements / contents value in the area protected bythe Dubuque Levee. To determine the potential number of people that might be impacted by levee failure, the average household size from the 2010 U.S. Census was multiplied by the number of dwellings (residential structures) in the levee protected areas. This analysis is limited due to the uncertainty of how many separate households are in the multi-residential structures. Table 3.26.

Future Development Future development located downstream from dams in floodplains or inundation zones and/or in levee protected areas would increase vulnerability to dam or levee failure. Climate Change lmpacts Increased frequency of precipitation and precipitation extremes leading to flooding could cause additional stress on dam and levee structures. Dubuque County, lowa 3.65 Multi-jurisdictional Hazard Mitigation Plan 2018 Dam/Levee Failure Hazard Summary by Jurisdiction The magnitude of"catastrophic" was assigned to the unincorporated county, Dubuque and Cascade since theses jurisdictions are either downstream of high hazard dams or behind the levees, or both and due to the potential for loss of life in the unlikely event of failure of any of these flood control structures. For jurisdictions that would be impacted by low hazard dams, failure or no dams, this hazard was determined to be "not applicable".

There are four types of drought conditions relevant to lowa: Meteoroloqical drought is defined on the basis of the degree of dryness (in comparison to some "normal" or average amount) and the duration of the dry period. A meteorological drought must be considered as region-specific since the atmospheric conditions that result in deficiencies of precipitation are highly variable from region to region. Hvdroloqical drought is associated with the effects of periods of precipitation (including snowFall) shorffalls on surface or subsurface water supply (e.g., streamflow, reservoir and lake levels, ground water). The frequency and severity of hydrological drought is often defined on a watershed or river basin scale. Although all droughts originate with a deficiency of precipitation, hydrologists are more concerned with how this deficiency plays out through the hydrologic system. Hydrological droughts are usually out of phase with or lag the occurrence of meteorological and agricultural droughts. It takes longer for precipitation deficiencies to show up in components of the hydrological system such as soil moisture, streamflow, and ground water and reservoir levels. As a result, these impacts are out of phase with impacts in other economic sectors. Aqricultural drought focus is on soil moisture deficiencies, differences between actual and potential evaporation, reduced ground water or reservoir levels, and so forth. Plant water demand depends on prevailing weather conditions, biological characteristics of the specific plant, its stage of growth and the physical and biological properties of the soil. Socioeconomic drought refers to when physical water shortage begins to affect people. The four different types of drought can all occur in lowa. A meteorological drought is the easiest to determine based on rainfall data and is an easier drought to monitor from rain gauges and reports. A hydrological drought means that stream and river levels are low, which also has an impact for surface water and ground water irrigators. In addition, in-stream discharges that fall below a pre-required level also place the State in regulatory difficulty with U.S. Fish and Wildlife and with neighboring states over cross-border flowage rights. An agricultural drought represents difficulty for lowa's agricultural-based economy and is also relatively easy to monitor based on crop viabilities for different regions. The National Drought Mitigation Center (NDMC) located at the University of Nebraska in Lincoln provides a clearinghouse for information on the effects of drought, based on reports from media, Dubuque County, lowa 3.67 Multi-jurisdictional Hazard Mitigation Plan 2018 observers and other sources. NDMC's website is found at http://www.drouqht.unl.edu/. Specific drought impacts by county are recorded at http://drouqhtreporter.unl.edu/. The NDMC categorizes impacts of drought as economic, environmental, or social. Many economic impacts occur in agriculture and related sectors, including forestry and fisheries, because of the reliance of these sectors on surface and subsurface water supplies. In addition to obvious losses in yields in both crop and livestock production, drought is associated with increases in insect infestations, plant disease and wind erosion. Droughts also bring increased problems with insects and disease to forests and reduce growth. The incidence of forest and range fires increases substantially during extended droughts, which in turn places both human and wildlife populations at higher levels of risk. Income loss is another indicator used in assessing the impacts of drought because so many sectors are affected. Although drought is not predictable, long-range outlooks may indicate an increased chance of drought, which can serve as a warning. A drought period can last for months, years, or even decades. It is rarely a direct cause of death, though the associated heat, dust and stress can all contribute to increased mortality. Warninq Time Score: 1-24+ Hours Duration Score: 4-more than 1 week Geographic Location/6ctent According to the 2012 Census of Agriculture, of the 608 square miles (389,120 acres) of land area in Dubuque County, 74.9 percent (291,441 acres) is utilized for agricultural purposes. There were 1,462 farms with an average size of 199 acres per farm. Although the entire planning area in Dubuque County is at risk to drought, the agricultural areas are more vulnerable to the immediate effects of drought. The map in Figure 3.1 in the Animal/Plant/Crop Disease hazard section displays the locations of various cropland uses in Dubuque County. Previous Occurrences According to the lowa Environmental Mesonet, the mean annual precipitation for Dubuque County is 34.95 inches. In average years, this represents enough rainfall to prevent drought; however, successive years of below-average rainfall are the cause drought impacts in the planning area. Table 3.28 provides the rainfall history at the Dubuque weather station from 1951 to February 2017. Complete years with less than 30 inches of rain include 1952, 1955, 1956, 1958, 1976, 1988, 1989, 1995, 1997, 2005, and 2012. The lowest annual precipitation on record occurred in 1988 with 22.7 inches. Table 3.28.

MATE&station=1A2364&report=17 According to the National Drought Mitigation Center's Drought Impact Reporter, during the 10- year period from January 2007 thru December 2016, 86 listed drought impacts were noted for the State of lowa. Of these impacts, 5 were reported to affect Dubuque County. The following are the categories and reported number of impacts. Note: some impacts have been assigned to more than one category: • Agriculture -2 • Plants &Wildlife - 2 • Tourism & Recreation - 1 • Water Supply & Quality- 3 Impacts of recent drought periods in lowa that affected Dubuque County are provided below. Unless otherwise indicated, these impacts are from the Drought Impact Reporter. • July 6, 2016 -Corn yield potential down in lowa • October 7, 2012 -Crops in Coulee Region of Midwest manifest signs of drought stress • September 5, 2012 -Carp died from depleted, warm pond at state park in eastern lowa • November 1-20, 2010 -According to National Climatic Data Center (NCDC), the drought that began in June and worsened during the summer and into the fall finally began to show improving conditions in November. This was due to somewhat more rainfall as the weather pattern became a bit more active. For the first two weeks of the month all of eastern IA, northwest and western IL and extreme northeast MO was in a severe drought (D2), according to the U.S. Drought Monitor. However, during the last half of the month only portions of northeast and eastern IA and northwest IL were still in a severe drought. The remainder of the area had improved to a moderate drought (D1) classification. • August 7-28, 2012 -According to National Climatic Data Center (NCDC), the drought became Extreme during the first week of August across all of eastern lowa as persistent high pressure remained centered just to our west. The persistent ridge of high pressure would shift westward during the remainder of the month of August, allowing for cooler air and some much need precipitation to affect portions of the region and therefore an improvement of drought conditions beginning in the second week of August and continuing through the remainder of the month. Precipitation across lowa was a quarter to a half inch below normal for the month. Drought conditions improved slightly during the second week to Severe Drought between Highway 34 and Interstate 80 with Extreme Drought continuing to the north and south of this area. The area under Extreme Drought decreased by the fourth week in August covering only the areas south of Highway 24, and along the Highway 20 corridor all other areas were in Severe Drought. • August 1, 2012 -Oak trees in northeastern lowa dropping poorly developed acorns early. Dubuque County, lowa 370 Multi-jurisdictional Hazard Mitigation Plan 2018 • August 1, 2012 -Trout stocking operations suspended in northeastern lowa. • July 10-31, 2012 -According to National Climatic Data Center (NCDC), A persistent ridge of high pressure across the region produced warmer than normal temperatures and below normal rainfall during the month of July. Mean temperatures for the month were 4 to 7 degrees above normal. Rainfall for the month totaled only around an inch or less which was about 3 to 5 inches below normal. This caused the drought that began in June to worsen and expand across eastern lowa, northwest and western Illinois and extreme northeast Missouri. According to the U.S. Drought Monitor, extreme northeast Missouri was in a D2 severe drought on July 3, 2012. By the 10th of July, the severe drought category also included much of eastern lowa roughly north of Interstate 80, and northwest Illinois north of Highway 30. On July 17, the Drought Monitor classified all of eastern lowa, northwest and western Illinois and extreme northeast Missouri as severe drought. However, due to the persistent heat and lack of rainfall the drought continued to worsen. By the last week of July, the entire region was either in a D2 severe or D3 extreme drought. Crops were showing stress due to the heat and reduced crop yields were being noted. Because the severe to extreme drought continued into August exact damage amounts to the crops are not known at this time. Table 3.29 below provided by the U.S. Drought Monitor, summarizes the historical drought conditions for lowa by intensity and percent area from 2007 through 2016. Portions of lowa were in exceptional drought intensity in 2012 and 2013 during this 10-year timeframe. Table 3.29.

With the extensive drought conditions during the years of 2012, 83 percent of the 10-year crop losses came from this year alone. Table 3.30.

Lack of precipitation for a given area is the primary contributor to drought conditions. Since precipitation levels cannot be predicted in the long term, the following indices can be used to determine the probability of future occurrences of drought. The following are the indices: • Palmer Z Index monitors short-term monthly moisture conditions when depart from normal. • Palmer Drought Severity Index measures the duration and intensity of the long-term (meteorological) drought patterns. • Palmer Hydrological Drought Index measures long-term (hydrological) drought and wet conditions reflecting groundwater and reservoir levels. • Standardized Precipitation Index is a probability index that considers only precipitation. This is important to farmers to estimate soil moisture. In the past 10 years, there have been nine years with crop insurance claims as a result of drought in Dubuque County. If this trend continues, this results in a probability of 90% of agricultural impacts as a result of drought in any given year. The probability rating for this hazard is "Highly Likely". Probabilitv Score: 4—Highly Likely Vulnerabilitv Overview Dubuque County jurisdictions are impacted by drought because it is an expensive weather disaster; it reduces agricultural productivity and causes a strain on urban water supplies. In Dubuque County, lowa 372 Multi-jurisdictional Hazard Mitigation Plan 2018 Dubuque County, farmers bear the most direct stress from drought as wells may run dry; crops wilt and die, and forage for livestock becomes scarce and costly. Dubuque County has 1,462 farms in the County that cover 291,441 acres of land. This translates to 74.9 percent of the surface land in the County being used for agriculture. Therefore, the planning area has a high exposure to this hazard. Aside from agricultural impacts, other losses related to drought include increased costs of fire suppression and damage to roads and structural foundations due to the shrink dynamic of expansive soils during excessively dry conditions. Drought also presents hazards to public health in extreme cases, where drinking water production cannot keep up with demand. Water wells become less productive during drought and a failure of remaining productive wells (due to power outage, etc.) can cause public drinking water supplies to become compromised. According to the 20131owa Hazard Mitigation Plan, of the 8 hazards for which data was available to estimate annualized losses, drought ranked 2"'with $424 million in annualized losses based on data spanning an 18-year period. Losses associated with this hazard can be very high, particularly associated with agriculture. Crop insurance coverage mitigates the adverse economic impacts somewhat. Maqnitude Score: 3—Critical Potential Losses to E�cisting Development Areas associated with agricultural use are vulnerable to drought conditions which could result in a decrease in crop production or a decrease in available grazing area for livestock. Drought has no real effect on houses and buildings. The impacts would be minimal in terms of landscaping. Rationing water supplies would most likely be the worst-case scenario impact. According to the ten-year period from USDA's Risk Management Agency, the amount of claims paid for crop damage as a result of drought in Dubuque County was $31,972,518.36. According to the 2015 lowa Crop Insurance Profile from USDA's Risk Management Agency, 89 percent of the insurable crops in lowa are insured with USDA Crop Insurance. To factor in estimated losses to insurable crops that are not insured, the 89 percent crop insurance coverage was factored in to provide an adjusted estimate of losses. According to this calculation, estimated annualized losses total $2,777,062 (see Table 3.31). Considering the value of crops from the 2012 Census of Agriculture as baseline crop exposure, the estimated annual losses from drought was determined minimal compared to the value of the insurable crops.

In addition, increases in population add additional strain on water supply systems to meet the growing demand for treated water. Climate Change lmpacts For the most part, climate change studies have shown increases in precipitation, rather than decreases. However, drought cycles still continue. Climate change studies have also shown some increases in average temperatures. If this occurs during a drought cycle, the drought impacts will be exacerbated and increased agricultural losses will be sustained. Drought Hazard Summary by Jurisdiction As discussed in the drought previous occurrences and vulnerability sections, the majority of the damages seen historically as a result of drought are to crops and other agriculture-related activities. Therefore, the magnitude of the impacts is greater in the unincorporated areas. In the cities and school districts, the frequency of drought conditions would be the same, but the magnitude would be less with lawns and local gardens affected, and leading to expansive soil problems around foundations. If drought conditions are severe and prolonged, water supplies could also be affected.

Expansive soils can cause physical damage to building foundations, roadways, and other components of the infrastructure when clay soils swell and shrink due to changes in moisture content. The effects of expansive soils are most prevalent in regions of moderate to high precipitation where prolonged periods of drought are followed by long periods of rainfall. These conditions exist in Dubuque County from time to time. Warninq Time Score: 1-24 + hours The warning time for expansive soils is consistent with other geologic hazards that occur slowly overtime. Duration Score: 1—Less than 6 hours The duration of response to this hazard is limited in the State of lowa. Although prolonged periods of drought are a primary indicator of risk followed by forecasted periods of precipitation, the response to expansive soils in lowa is limited and is in large part coupled with response to flash flooding and river flooding. Dubuque County, lowa 375 Multi-jurisdictional Hazard Mitigation Plan 2018 Geographic Location/6ctent Figure 3.13 shows a map of the swelling potential of soils in lowa. Dubuque County has soil units near the Mississippi River that contain abundant clay, having high swelling potential. The soil in remainder of the county contains little or no swelling clay. This hazard primarily impacts the following jurisdictions: Unincorporated Dubuque County, Balltown, Rickardsville, Sherrill, Durango, Sageville, Asbury, Graf, Centralia, Peosta, Dubuque, and Zwingle.

Previous Occurrences Streets and parking lots throughout the County are damaged every year by the effects of expansive soils as well as underground water lines that are damaged as the soil expands and contracts at varying levels along a water line. The frequency of damage from expansive soils can be associated with the cycles of drought and heavy rainfall, which reflect changes in moisture content. Damages occur with isolated incidents and affected property owners, local governments, and businesses generally make any necessary repairs. Dubuque County, lowa 376 Multi-jurisdictional Hazard Mitigation Plan 2018 Probability of Future Occurrence There will continue to be some damage to paved areas and foundations in Dubuque County due to swelling soils every year. It is unlikely that these damages will become greater in the future unless new development occurs in areas where the hazard is more severe. Certain buildings and construction practices could be put in place to lessen these impacts. Since some damage occurs annually, the probability rating is "Highly Likely". Probabilitv Score: 4—Highly Likely Vulnerabilitv Overview While the entire planning area is vulnerable to some structural damage as a result of shrinking, and expanding soils, there is no data available to determine damage estimates for this hazard. In most cases, individual property owners, local governments, and businesses pay for repairs to damages caused by this hazard. Underground utility lines such as water and sewer pipes are also at risk to damages associated with expansive soils. However, there is no data to support damages and costs associated with this hazard at this time. This hazard does not impact human safety. Maqnitude Score: 2—Limited Potential Losses to E�cisting Development Existing development will continue to be vulnerable to expansive soils. Future Development Additional future development in the planning area will also be vulnerable to this hazard. Dubuque County, lowa 3.77 Multi-jurisdictional Hazard Mitigation Plan 2018 E�cpansive Soi/s Hazard Summary by Jurisdiction The jurisdictions that have soils with abundant clay and high swelling potential include: Unincorporated Dubuque County, Balltown, Rickardsville, Sherrill, Durango, Sageville, Asbury, Graf, Centralia, Peosta, Dubuque, Zwingle, and Dubuque CSD. Therefore, the Probability and Magnitude for these jurisdictions are 4-highly likely and 2-limited respectively. Since the remaining jurisdictions are in areas where the soil has low swelling potential, the probability and magnitude for these jurisdictions is 1-unlikely and 1-negligible.

During these conditions, the human body has diffculties cooling through the normal method of the evaporation of perspiration. Health risks rise when a person is over exposed to heat. The most dangerous place to be is in a permanent home, with little or no air conditioning. Those at greatest risk for heat-related illness include people 65 years of age and older, people who are overweight, and people who are ill or on certain medications. However, even young and healthy individuals are susceptible ifthey participate in strenuous physical activities during hot weather. In agricultural areas, the exposure of farm workers, as well as livestock, to extreme heat is a major concern. ououque counry,iowa a�e MUltljutlstllNonal HazaN Mltlgatlon Plan 2018 Table 3.32 lists typical symptoms and health impacts of exposure to extreme heat.

The expected severity of the heat determines whether advisories or warnings are issued. A common guideline for issuing excessive heat alerts is when the maximum daytime Heat Index is expected to equal or exceed 105 degrees Fahrenheit (°F) and the night time minimum Heat Index is 80°F or above for two or more consecutive days. A heat advisory is issued when temperatures reach 105 degrees and a warning is issued at 115 degrees.

Previous Occurrences Figure 3.15 shows heat-related deaths in the United States using two methodologies. One method shows deaths for which excessive natural heat was stated as the underlying cause of death from 1979 to 2013. The other data series shows deaths for which heat was listed as either the underlying cause or a contributing cause, based on a broader set of data that at present can only be evaluated back to 1999. For example, in a case where cardiovascular disease was determined to be the underlying cause of death, heat could be listed as a contributing factor because it can make the individual more susceptible to the effects of this disease. Because excessive heat events are associated with summer months, the 1999-2013 analysis was limited to May through September. According to the National Weather Service, in 2015, 45 people died nationally as a result of extreme heat. In 2014, there were 20 heat-related deaths. In 2013 there were 92 and in 2012, there were 155 deaths. The 10-year average for heat related fatalities is 124. Only one heat- related death has been reported for lowa within the last 10 years, occurring in 2006. (Source: http://www.nws.noaa.qov/om/hazstats.shtml). On average, the hottest months of the year are July and August. According to the High Plains Regional Climate Center, the average temperature in Dubuque County for the month of July is 72.61 degrees Fahrenheit (°F) with an average maximum temperature of 83.28 °F; and the average temperature for the month of August is 70.63 °F with an average maximum temperature of 81.35 °F.

When looking at only those events with a high temperature of 95 degrees Fahrenheit and higher that Dubuque County, lowa 3.81 Multi-jurisdictional Hazard Mitigation Plan 2018 lasted for 3 consecutive days or more, there were two occurrences during the 24-year period from 1993 to 2016. The following summarizes the National Weather Service Advisories, Watches, and Warnings for Heat or Excessive Heat in Dubuque County from 1986 to 2016 (31 years of data) • 19 Advisories • 3 Watches • 2 Warnings The National Climatic Data Center reported three regional heat events and one regional excessive heat event in and around the Dubuque County planning area: • July 25, 1997 — Regional Heat Event - Heat and high humidity teamed together produced excessive heat index values reaching 105 °F to 110 °F during the day. This came in the middle of an otherwise much cooler than normal summer and many claimed that their bodies were not properly acclimated and therefore unprepared for the sudden spike in temperatures and humidity. • July 19, 1999 - Regional Heat Event - A strong ridge of high pressure over the central U.S. produced very hot and humid conditions over the Midwest from mid to late July. Heat advisories and warnings were issued for portions of eastern lowa during the period. Temperatures around the 100 °F inark combined with dew points in the 70s produced heat indices of 105 °F to as high as 125 °F. Newspaper accounts indicate at least 19 people in Illinois, and 27 in Missouri, died from heat-related factors since July 19th. • July 4, 2012 — Regional Excessive Heat Event - A very hot and humid air mass surged into the Midwest during the long 4th of July holiday. The dangerous heat began about noon on July 4 with relief from the heat and humidity finally arriving during the evening of July 7. During this period, afternoon and early evening temperatures soared into the upper 90s to lower 100s with nighttime temperatures remaining well into the 70s. Combining the heat and humidity created heat index values of 105 °F to 115 °F during the afternoon and evening. The hottest day was Saturday July 7 when many locations reported afternoon maximum temperatures of 100 °F to 105 °F. • August 26, 2013 - Regional Heat Event - A large, nearly stationary upper level high centered over eastern Kansas and Missouri and a dome of unseasonably warm air aloft dominated the weather picture from August 26 through August 30, 2013. This was the hottest weather of the entire summer. Maximum temperatures soared into the 90s during much of this period with several locations reporting lower 100's on August 30. In fact, record high temperatures were either broken or tied at Cedar Rapids, lowa and Moline, Illinois during this heat wave. In addition to the heat, dew points were well into the 60s to lower 70s which pushed heat index values to 100 to 105, with a few locations reporting 110 °F. Schools without air-conditioning either canceled classes or dismissed students early. In many cities and towns, cooling centers were opened. Dubuque County, lowa 3.82 Multi-jurisdictional Hazard Mitigation Plan 2018 According to the USDA's Risk Management Agency, insured payments in Dubuque County for damages to crops as a result of heat from 2007-2016 totaled $1,930,640. There were no damages to crops as a result of hot wind. Table 3.33 shows the insurable crop insurance claims paid in Dubuque County as a result of heat. Table 3.33.

Probability of Future Occurrence Based on five (5) National Weather Service Heat/Excessive Heat Warnings and Watches from 1986 to 2016 (31 years), the probability of occurrence is 16 percent. This translates to a probability rating of"Occasional" Probabilitv Score: 2-0ccasional Vulnerabilitv Overview Those at greatest risk for heat-related illness and deaths include people 65 years of age and older, people who are overweight, and people who are ill or on certain medications. To determine jurisdictions within the planning area with populations that may be more vulnerable to extreme heat, demographic data was obtained from the U.S. Census Bureau on numbers of people in each jurisdiction that are over the age of 65 are seen in 0. Data was not available for overweight individuals and those on certain medications. Overall, lowans are older than the country as a whole. About 15 percent of its population is over 65 years, compared with 13 percent nationally. Dubuque County's population over 65 years is higher than the national and state averages at 15.8 percent. The participating jurisdictions with the highest percent of adults 65 and over in descending order are the cities of Balltown, Durango, Rickardsville, Luxemburg, Cascade, New Vienna, Holy Cross, Dyersville, Worthington, Sherill, Dubuque, and Bernard.

According to the 2015 lowa Crop Insurance Profile Report issued by the USDA's Risk Management Agency, 89 percent of lowa insurable crops were insured. To factor in estimated losses to insurable crops that are not insured, the 89 percent crop insurance coverage was factored in to provide an adjusted estimate of losses. According to this calculation, estimated annualized losses total $216,926 (see Table 3.35). Considering the value of crops from the 2012 Census of Agriculture as baseline crop exposure, the estimated annual losses from heat was determined to be minimal (0.18%) compared to the value of the insurable crops.

Another type of infrastructure damage that can occur as a result of extreme heat is road damage. When asphalt is exposed to prolonged extreme heat, it can cause buckling of asphalt- paved roads, driveways, and parking lots. Future Development Dubuque County is experiencing some population growth (2.4 percent since 2010). Therefore, the number of people vulnerable to extreme heat is also increasing slightly. Climate Change lmpacts The following climate change impacts relative to Extreme Heat were included in the 2010 Climate Change lmpacts on lowa report developed by the lowa Climate Change Impacts Committee. • Nighttime temperatures have increased more than daytime temperatures since 1970. • lowa's humidity has risen substantially, especially in summer, which now has 13 percent more atmospheric moisture than 35 years ago as indicated by a 3 - 5-degree F rise in dew- point temperature. This fuels convective thunderstorms that provide more summer precipitation. Both of these impacts could increase the number extreme heat events in the planning area as well as the potential for negative impacts on people and agriculture. 6ctreme Heat Hazard Summary by Jurisdiction Extreme heat is a regional hazard and impacts all jurisdictions in the planning area.

Ice jam flooding is a form of flash flooding that occurs when ice breaks up in moving waterways, and then stacks on itself where channels narrow. This creates a natural dam, often causing flooding within minutes of the dam formation. Riverine Flooding is discussed separately in Section 3.5.13 and flooding caused by dam failure is discussed in Section 3.5.2 respectively. Most flash flooding is caused by slow-moving thunderstorms or thunderstorms repeatedly moving over the same area. Flash flooding is an extremely dangerous form of flooding which can reach full peak in only a few minutes and allows little or no time for protective measures to be taken by those in its path. Flash flood waters move at very fast speeds and can move boulders, tear out trees, scour channels, destroy buildings, and obliterate bridges. Flash flooding often results in higher loss of life, both human and animal, than slower developing river and stream flooding. In some cases, flooding may not be directly attributable to a river, stream, or lake overflowing its banks. Rather, it may simply be the combination of excessive rainfall or snowmelt, saturated ground, and inadequate drainage. With no place to go, the water will find the lowest elevations— areas that are often not in a floodplain. This type of flooding, often referred to as sheet flooding, is becoming increasingly prevalent as development outstrips the ability of the drainage infrastructure to properly carry and disburse the water flow. In certain areas, aging storm sewer systems are not designed to carry the capacity currently needed to handle the increased storm runoff. Typically, the result is water backing into basements, which damages mechanical systems and can create serious public health and safety concerns. This combined with rainfall trends and rainfall extremes all demonstrate the high probability, yet generally unpredictable nature of flash flooding in the planning area. Although flash floods are somewhat unpredictable, there are factors that can point to the likelihood of flash floods occurring. Weather surveillance radar is being used to improve monitoring capabilities of intense rainfall. This, along with knowledge of the watershed characteristics, modeling techniques, monitoring, and advanced warning systems increases the warning time for flash floods. Dubuque County, lowa 3.86 Multi-jurisdictional Hazard Mitigation Plan 2018 Warninq Time Score: 2-12-24 hours warning time. This refers to the period of time prior to the event with heightened awareness that a flash flood could occur, not the issuance of a "flash flood warning" by the National Weather Service. Duration Score: 1—Less than 6 hours Geographic Location/6ctent The topography of Dubuque County is gently sloping (5 to 9 percent) to strongly sloping (9 to 30 percent) farmland with some steep bluffs near streams. Vegetal cover is typically pastureland grass, with some timber, especially near streams. The Mississippi River flows adjacent to the east limit of the county, flowing generally in a southeasterly direction. The Mississippi River is joined by the Little Maquoketa River system flowing east some 5 miles north of the City of Dubuque and the Caffish Creek system also flowing east. The western and southern portions of the county are drained by the North Fork Maquoketa River and by streams draining into that river which all tend to flow in a southern direction before joining the Maquoketa River some 30 miles south of the City of Dubuque. Land use in and around the floodplain is primarily agricultural. Flash flooding occurs in those locations of the planning area that are low-lying and/or do not have adequate drainage to carry away the amount of water that falls during intense rainfall events. According to NCDC and reports from the HMPC, the following locations have a history of flash flooding events: • City of Dubuque — Bee Branch Drainage Basin - St. Mary's Catholic Church, Elm Street, and the Historic Millwork District — Downtown Dubuque, Between 20th and 28th Streets and between Washington and Jackson Streets; 17th St and Locust St — Herber and Rupp Hollow Roads — Spring Valley Mobile Home Park — Kennedy Mall and JF Kennedy Road — Rockdale Road and Cedar Cross Road — English Mill Rd and N Cascade Rd, • City of Dyersville — North Fork of the Maquoketa River — Floyd Road and 180th Street • City of Durango — Paradise Valley Road • City of Cascade — Highway 151 between Cascade and Monticello. • City of New Vienna — New Wine Park • City of Sageville — Herber Road near John Deere Road closed due to mudslide. — Highway 52 at Rickardsville and Sageville Dubuque County, lowa 3.87 Multi-jurisdictional Hazard Mitigation Plan 2018 The National Weather Service has various flash flooding products that are issued to the public to provide information regarding upcoming and current flash flood threats (see Table 3.36).

Numerous businesses across town sustained Dubuque County, lowa 3.90 Multi-jurisdictional Hazard Mitigation Plan 2018 major damage. The costliest damage occurred at Scale Models, which sustained an estimated $150,000 in damage. Other businesses reported flooding to depths of 7 feet in their basements. About 100 people were evacuated from 60 homes. State officials set the preliminary damage estimates from Dyersville at $3 to $5 million. Five to six feet of water flooded city streets in downtown. Major road damage resulted, including buckled roads and pavement washed away. Approximately 25 residential blocks were affected. Basements in over 60 houses were flooded with water from 2 feet deep up to the rafters. Flooding was reported between 20th and 28th Streets and between Washington and Jackson streets. State damage estimates were set at $17 million in Dubuque. • May 2004 Flooding: A low level jet developed the first of two squall lines in western lowa that raced east across lowa and Illinois. The first squall line travelled north of the stationary front across lowa and Northern Illinois. The storms brought renewed heavy rain to areas that had been saturated by storms just hours earlier. New Wine County Park evacuated. • June 2004 Flooding: Scattered thunderstorms developed ahead of a cold front moving east through lowa. By the evening, a surface low had developed along the cold front as it moved into Eastern lowa. This enhanced the overall lift in a near tropical atmosphere and produced copious amounts of rain in a very short time period. This resulted in flash flooding across parts of Northeast lowa and Northwest Illinois due to the hilly terrain. Water over numerous roads in north part of county; Highway 52 closed at Rickardsville and Sageville • July 2007 Flooding: Rainfall totals of 2 to 6 inches over a 7-hour period resulted in numerous flooded roads, creeks, streams, and rivers throughout Dubuque County. The following locations reported flooding during this event: Rupp Hollow Rd, W Locust St and 22nd St, 17th St and Locust St, all along Locust St, Downtown Dubuque, Highway 52 on the north side of town, Highway 52 and Clayhill Rd, 22nd St and White St, many roads north of Highway 20, English Mill Rd and N Cascade Rd, Paradise Valley Rd and Highway 52, and several areas along Highway 52 from Sageville, IA to Holy Cross, IA. It was also reported that portions of the Maquoketa River were well out of its banks and the river level was rising rapidly. • June 2008 Flooding: Heavy rain-producing showers and thunderstorms moved across eastern lowa during the morning and early afternoon hours of June 8 producing damaging winds and flash flooding. Heavy rains caused the Little Maquoketa River to rise rapidly resulting in some flash flooding of Highway 52 near Durango, IA around 2:00 pm June 8. The highway was closed until the flood waters receded. Some Durango residences along the river were evacuated. • July 2010 Flooding: Heavy rains of 4 to 8 inches which fell in about 12 hours resulted in flash flooding of much of Dubuque County during the morning of July 23. At 1245 am CDT, about 15 inches of water was flowing in some streets in Dubuque as torrential rains continued. At 122 am CDT, the baseball field near the junction of Coffee Creek and Dubuque County, lowa 3.91 Multi-jurisdictional Hazard Mitigation Plan 2018 the North Fork Maquoketa River in New Vienna was flooded with 4 feet of water. In addition, the North Fork of the Maquoketa River flooded and flood waters started to reach the edges of some residences in town. By 539 am CDT, Highway 52 north of Dubuque was closed due to flooding. In Dyersville, both Bear Creek and the North Fork Maquoketa River overtopped, flooding various streets around town including a 3-block section of downtown near the historic basilica. One neighborhood was surrounded by water, forcing emergency crews to stage personnel in the isolated area. About 50 homes in Dyersville were affected either by flooded basements or by loss of access. • July 2011 Flooding: Torrential downpours of rain fell across much of Dubuque County during the evening of July 27 and early morning hours of July 28 resulting in flash flooding of much of the county, especially in Dubuque, IA. Rainfall totals of 7 to 15 inches were common across the area, with most of the rain falling in under 12 hours. Numerous roads and bridges were washed out and many others closed, causing Dubuque County to run out of barricades. Several neighborhoods were evacuated, including the Valley Hill trailer park where the water was 6 feet deep. Many creeks in the area raged out of their banks, including Catfish Creek. Very early estimates of damage to infrastructure alone exceeded $3 Million. Numerous roads and streets were flooded, with some eroded or washed away completely. Among the hardest hit areas was the vicinities of St. Mary's Catholic Church, Elm Street and the Millwork District. The Dubuque water treatment plant was heavily damaged, with estimates between $1.5 Million and $2 Million. A basement wall caved in at 1790 Chaney Road on Dubuque's West End. • July 2016 Flooding: A disturbance interacting with a frontal system produced an area of severe thunderstorms with numerous damaging winds, some flash flooding and a few isolated, brief tornadoes. Amateur radio report received of water over several roads in downtown Dubuque including Central Avenue and Jackson Streets which were closed. The US Army Corps of Engineers, Cold Regions Research and Engineering Laboratory (CRREL) maintains a database of historic ice jams. According to a query of that database from 1950 to the present, eight recorded ice jams have occurred in Dubuque County: six within the City of Dubuque; one in the City of Durango; and one in the City of New Vienna. (Source: http://rsqisias.crrel.usace.armv.mil/apex/f?p=524:1). Probability of Future Occurrence The frequency of past events is used to gauge the likelihood of future occurrences. The events from NCDC that occurred on the same day were combined to determine the total number of 34 flash flooding events in the planning area over the 24-year period from 1993 to 2016. This translates to a 100 percent likelihood of flash flooding somewhere in the planning area in any given year. Therefore, the probability rating is "Highly Likely". Probabilitv Score: 4—Highly Likely Dubuque County, lowa 3.92 Multi-jurisdictional Hazard Mitigation Plan 2018 Vulnerabilitv Vulnerability Overview Water over low-lying roads and bridges is the most frequent impacts associated with flash flooding that has occurred in the planning area. This can cause wash out of bridge abutments and erosion/scour damage on roads. There is potential for loss of life if motorists drive into moving water. However, public education campaigns have helped to educate citizens about not driving through moving water. Building damage is generally limited to water in basements where rain is too intense for drainage systems and natural drainage to carry water away from the structure. In addition, when combined storm/sanitary sewer systems are overloaded, this can result in sewer back-up. In general, flash-flooding is short in duration and government services and business operations are not impacted. However, flash flooding within Dubuque County has caused over $30 million dollars in property damages. Maqnitude Score: 3�ritical. The magnitude was determined to be critical. Potential Losses to E�cisting Development When roads and bridges are inundated by water, damage often occurs as the water scours materials around bridge abutments and gravel roads. The water can also cause erosion undermining road beds. In some instances, steep slopes that are saturated with water may cause mud or rock slides onto roadways. These damages can cause costly repairs for state, county, and city road/bridge maintenance departments. When sewer back-up occurs, this can result in costly clean-up for home and business owners as well as present a health hazard. Based on loss estimates reported by NCDC, property losses averaged $1,275,250 per year over the 24-year period from 1993 to 2016. Future Development In planning future development, jurisdictions in the planning area should avoid development in low-lying areas near rivers and streams or where interior drainage systems are not adequate to provide drainage during heavy rainfall events. Future development should also take into consideration the impact of additional impervious surfaces to water run-off and drainage capabilities during heavy rainfall events. Climate Change lmpacts One of the climate change impacts noted in the 2010 Climate Change lmpacts on lowa report by the lowa Climate Change Impacts Committee is the increase in frequency of severe precipitation events. Figure 3.17 shows that all of lowa is in the region with a 31% increase in very heavy precipitation from 1958 to 2007. For this study, very heavy precipitation was defined as the heaviest 1% of all events. Dubuque County, lowa 3.93 Multi-jurisdictional Hazard Mitigation Plan 2018 Figure 3.17.

Dubuque County, lowa 3.94 Multi-jurisdictional Hazard Mitigation Plan 2018 Flash Flood Hazard Summary by Jurisdiction For the jurisdictions indicated in previous flash flood events reported to NCDC, mentioned in the episode narrative, or that indicated specific flash flooding previous events, the probability was determined to be "highly likely" (4). For the remaining jurisdictions, the probability was determined to be "occasional" (2). For the school districts, the probability was also determined to be "occasional". Although impacts were not mentioned for some cities or the school districts, flash flooding can still occur in the future if the amount of rainfall received in a given time exceeds the capability of drainage features and natural drainage to carry the water away.

The State has the largest number of CRP contracts in the nation, totaling over 1.5 million acres. Most of this land is planted in cool and warm season grass plantings, tree plantings and riparian buffer strips. There is an additional 230,000 acres in federal ownership and conservation easements. Wildfires are frequently associated with lightning and drought conditions, as dry conditions make vegetation more flammable. As new development encroaches into the wildland/urban interface more and more structures and people are at risk. On occasion, ranchers and farmers intentionally set fire to vegetation to restore soil nutrients or alter the existing vegetation growth. Also, individuals in rural areas frequently burn trash, leaves and other vegetation debris. These fires have the potential to get out of control and turn into wildfires. The risk of wildfires is a real threat to landowners across the State. The National Weather Service monitors the conditions supportive of wildfires in the State on a daily basis so that wildfires can be predicted, if not prevented. The risk factors considered are: • High temperature • High wind speed • Fuel moisture (greenness of vegetation) • Low humidity • Little or no cloud cover Warninq Time Score: 4—Minimal or no warning time. Duration Score: 1—Less than 6 hours Geographic Location/6ctent Wildland/Grass fires are most likely to occur in the Wildland Urban Interface (WUI). This is the area where houses meet or intermingle with undeveloped wildland vegetation. Within the WUI, there are two specific areas identified: 1) Interface and 2) Intermix. The interface areas are those areas that abut wildland vegetation and the Intermix areas are those areas that intermingle with wildland areas. As can be seen in Figure 3.18, Dubuque County has a moderate amount of intermix areas (red) and no interface areas (yellow).

Through the National Fire Incident Reporting System (NFIRS), the lowa State Fire Marshal's Office collects and reports fire incidents throughout the State. NFIRS is a repository of Dubuque County, lowa 3.97 Multi-jurisdictional Hazard Mitigation Plan 2018 statistical data reported by participating fire departments. The State Fire Marshal's Division was unable to provide the historical grass/wildland fire data at this time. Probability of Future Occurrence Historical data was not available to document the average number of wildland/grass fires per year. The HMPC stated that field fires do occur, but the jurisdictions in the county have not experienced large scale wildfires. Since statistical data was unavailable to determine a quantitative probability, a qualitative probability is based on the anecdotal descriptions from the HMPC. The probability rating for this hazard is "Occasional". Probabilitv Score: 2-0ccasional Vulnerabilitv Overview Areas that are most vulnerable to wildfire are agricultural areas where land is burned, rural areas where trash and debris are burned, and the wildland-urban interface/intermix areas. To demonstrate how vulnerability to this hazard varies by jurisdiction, the 2010 spatial data indicating acreage of Wildland Urban Interface/Intermix areas from the SILVIS Lab, Department of Forest Ecology and Management, University of Wisconsin-Madison was compared against the corporate boundary layer for the planning area.

Homes built in rural areas are more vulnerable since they are in closer proximity to land that is burned and homeowners are more likely to burn trash and debris in rural locations. The vulnerability of structures in rural areas is exacerbated due to the lack of hydrants in these areas for firefighting and the distance required for firefighting vehicles and personnel to travel to respond. Potential losses to crops and rangeland are additional concerns. Maqnitude Score: 2—Limited Future Development Future development in the wildland-urban interface/intermix areas would increase vulnerability to this hazard.

If these conditions occur, the occurrence of wildfire would be expected to increase as was seen recently in 2012.

Chemicals are manufactured and used in increasing types and quantities. Each year over 1,000 new synthetic chemicals are introduced and as many as 500,000 products pose physical or health hazards and can be defined as "hazardous chemicals". Hazardous substances are categorized as toxic, corrosive, flammable, irritant, or explosive. Hazardous material incidents generally affect a localized area. Fixed Hazardous Materials Incident A fixed hazardous materials incident is the accidental release of chemical substances or mixtures during production or handling at a fixed facility. Transportation Hazardous Materials Incident A transportation hazardous materials incident is the accidental release of chemical substances or mixtures during transport. Transportation Hazardous Materials Incidents in Dubuque County can occur during highway or air transport. Highway and rail accidents involving hazardous materials pose a great potential for public exposures. Both nearby populations and motorists can be impacted and become exposed by accidents and releases. Barge accidents involving hazardous material pose potential for exposure through contamination of the water as well as populations near the point of release. If airplanes carrying hazardous cargo crash, or otherwise leak contaminated cargo, populations and the environment in the impacted area can become exposed. Pipeline Incident A pipeline transportation incident occurs when a break in a pipeline creates the potential for an explosion or leak of a dangerous substance (oil, gas, etc.) possibly requiring evacuation. An underground pipeline incident can be caused by environmental disruption, accidental damage, or sabotage. Incidents can range from a small, slow leak to a large rupture where an explosion is possible. Inspection and maintenance of the pipeline system along with marked gas line locations and an early warning and response procedure can lessen the risk to those near the pipelines.

Truck Transport Hazardous materials can be transported on any of the roads in Dubuque County. Numerous major US and state highways run through Dubuque County. The City of Dubuque is the major hub for the four-lane US Highway 20 that runs east west through Dubuque County extending into lowa and Illinois. Four-lane US Highway 61 extends north south from the City of Dubuque and extending into Wisconsin on the north and to the Quad Cities and beyond to the south. Four-lane US Highway 151 extends from the City of Dubuque and into Wisconsin on the north and to Cedar Rapids and beyond to the southwest. US Highway 52 runs north-south generally following the Mississippi River and extending north from Dubuque County through lowa into Minnesota and to the south through Bellevue and Sabula before entering into Illinois. The major highways are listed below: • US Highway 20 • US Highway 52 • US Highway 61 • US Highway 151 • lowa Highway 3 • lowa Highway 32 • lowa Highway 136 Numerous paved county roads connect all of the incorporated cities and unincorporated towns throughout the county. Agriculture is important to the economy of Dubuque County As a result, along with other chemicals, chemicals utilized in agriculture are frequently transported along county and local roadways. Industrial areas in Dubuque County are primarily located in three areas around the City of Dubuque. The first area is to the south along Highways 52, 151 and 61. The second is located west of the City of Dubuque along Highway 20 and extends to Peosta. The third area is along Highway 52 North in the Couler Valley and Little Maquoketa River outlet to the Mississippi River. These industrial areas have the potential for use of hazardous chemicals. As a result, incidents may occur more frequently in these areas. Dubuque County, lowa 3.104 Multi-jurisdictional Hazard Mitigation Plan 2018 Figure 3.21.

This could necessitate evacuation of large areas. In the rural unincorporated areas where population densities are low, even in the event of a large release the number of homes that may need to be evacuated would be significantly lower than in an urban environment. Immediate dangers from hazardous materials include fires and explosions. The release of some toxic gases may cause immediate death, disablement, or sickness if absorbed through the skin, injected, ingested or inhaled. Contaminated water resources may be unsafe and unusable, depending on the amount of contaminant. Some chemicals cause painful and damaging burns if they come in direct contact with skin. Contamination of air, ground, or water may result in harm to fish, wildlife, livestock and crops. The release of hazardous materials into the environment may cause debilitation, disease, or birth defects over a long period of time. Loss of livestock and crops may lead to economic hardships within the community. The occurrence of a hazmat incident many times shuts down transportation corridors for hours at a time while the scene is stabilized, the product is off-loaded and reloaded on a replacement container. Dubuque County, lowa 3.108 Multi-jurisdictional Hazard Mitigation Plan 2018 Previous Occurrences In lowa, hazardous materials spills are reported to the Department of Natural Resources. According to lowa Administrative Code Chapter 131, Notification of Hazardous Conditions, any person manufacturing, storing, handling, transporting, or disposing of a hazardous substance must notify the Department of Natural Resources and the local police department or the office of the sheriff of the affected county of the occurrence of a hazardous condition as soon as possible but not later than six hours after the onset of the hazardous condition or the discovery of the hazardous condition. The Department of Natural Resources maintains a database of reported spills. According to the DNR database, from 2000 to 2016 (17 years), there have been 261 hazardous materials spills reported in Dubuque County. Table 3.43 provides a summary of the reported spills during this time period for each jurisdiction indicated in the database as well as the mode of the spill. According to this data, the most spills occurred in the City of Dubuque (150) and most spills occurred during handling and storage (97) followed by transportation (92) Table 3.44 that follows summarizes the spills by material type.

From 1996 to 2015, there were no reported pipeline incidents in Dubuque County. Probability of Future Occurrence From 2000 to 2016 (17 years), there have been 261 spills reported to lowa DNR. This computes to an annual average of more than 15 hazardous materials spills per year. Therefore, the probability of future occurrence of hazardous materials incidents is determined to be "Highly Likely". Probabilitv Score: 4—Highly Likely Vulnerabilitv Vulnerability Overview A hazardous materials incident can occur almost anywhere. So, all jurisdictions are considered to have at least some vulnerability to this hazard. People, pets, livestock, and vegetation in Dubuque County, lowa 3.110 Multi-jurisdictional Hazard Mitigation Plan 2018 close proximity to facilities producing, storing or transporting hazardous substances are at higher risk. Populations downstream, downwind and downhill of a released substance are particularly vulnerable. Depending on the characteristics of the substance released, more people, in a larger area may be in danger from explosion, absorption, injection, ingestion, or inhalation. Most of the hazardous materials incidents that have occurred in Dubuque County are localized and are quickly contained or stabilized. Depending on the characteristic of the hazardous material or the volume of product involved, the affected area can be as small as a room in a building or as large as 5 square miles or more. Many times, additional regions outside the immediately affected area are evacuated for precautionary reasons. More widespread effects occur when the product contaminates the municipal water supply or water system such as river, lake, or aquifer. Spills can be costly to clean up due to the specialized equipment and training, and disposal sites that are necessary. Although the majority of spills are small and within local capabilities to respond quickly, the potential exists for large spills due to the industries in the planning area. The magnitude was determined to be "Limited". Maqnitude Score: 1—Limited Potential Losses to E�cisting Development The impact of this type of disaster will likely be localized to the immediate area surrounding the incident. The initial concern will be for people, then the environment. If contamination occurs, the spiller is responsible for the cleanup actions and will work closely with responders in the local jurisdiction, the lowa Department of Natural Resources, and the Environmental Protection Agency to ensure that cleanup is done safely and in accordance with federal and state laws. As mentioned, it is difficult to determine the potential losses to existing development because of the variable nature of a hazardous materials spill. For example, a spill of a toxic airborne chemical in a populated area could have greater potential for loss of life. By contrast a spill of a very small amount of a chemical in a remote rural area would be much less costly and possibly limited to remediation of soil. Data provided by the lowa Department of Natural Resources did not provide information relative to costs associated with cleaning up any of the spills or of any property damage that occurred. Without data on costs of previous events, it is not possible to determine potential costs associated with future spills. To analyze critical facilities at risk in the planning area, the inventory of critical and essential facilities and infrastructure in the planning area was compiled from data layers provided by Dubuque County. The compiled inventory consisted of 429 critical facilities. A comparison was made of the 429 critical facilities with the locations of Tier II Facilities to determine those critical/essential facilities/functions (other than Tier II facilities themselves) that are within Y mile of Tier II fixed chemical facilities. This analysis revealed 156 critical or essential facilities within Y mile of fixed chemical facilities with the Tier II reporting requirement. The results are summarized in Table 3.45 Dubuque County, lowa 3.111 Multi-jurisdictional Hazard Mitigation Plan 2018 Table 3.45.

Future Development The number and types of hazardous chemicals stored and transported through Dubuque County will likely continue to increase. Business growth along major transportation corridors could also increase the vulnerability to transportation hazardous materials spills. Hazardous Materials Hazard Summary by Jurisdiction It should be noted that all spills in the DNR database are associated with an incorporated area. Although spills do occur in the unincorporated area, they are recorded in the database associated with the nearest city. The probability score was based on the number of spills for each jurisdiction from the 17-year reporting period. The magnitude was determined to be "limited" based on the general types and quantities of spills that have occurred. Probability and magnitude for the schools were determined unlikely and negligible as hazardous materials are not generally stored on site.

The outbreak may be spread by direct contact with an infected person or animal, ingesting contaminated food or water, vectors such as mosquitoes or ticks, contact with contaminated surroundings such as animal droppings, infected droplets, or by aerosolization. lowa's public health and health care communities work to protect lowans from infectious diseases and preserve the health and safety of lowans by rapidly identifying and containing a wide range of biological agents. Local public health departments and the lowa Department of Public Health, Center for Acute Epidemiology investigate disease "outbreaks" of routine illnesses. There are a number of biological diseases/agents that are of concern to the State of lowa such as vaccine preventable disease, foodborne disease and community associated infections having significant impact on the morbidity of lowans. The following descriptions are general and it should be noted that individuals may experience more or less severe consequences. Vaccine Preventable Disease In the U.S., there are common infectious diseases that include polio, measles, diphtheria, pertussis, rubella, mumps, tetanus and Haemophilus influenzae type b that are now rare because of widespread use of vaccines. Routine childhood immunizations have helped protect both individuals and communities each year saving nearly $14 billion in direct medical costs and $69 billion in costs to society according to the U.S. Department of Health and Human Services, Centers for Disease Control and Prevention. Vaccine preventable diseases continue to threaten the health of lowans when children, adolescents and adults are un-immunized or under-immunized. Influenza Influenza (flu) is a viral infection of the nose, throat, bronchial tubes, and lungs. There are two main types of virus: A and B. Each type includes many different strains, which tend to change each year. In lowa, influenza occurs most often in the winter months. Illnesses resembling influenza may occur in the summer months, but these are usually the result of other viruses that exhibit symptoms commonly referred to as influenza-like illness or ILI. Influenza is highly contagious and is easily transmitted through contact with droplets from the nose and throat of an infected person during coughing and sneezing. Typical symptoms include headache, fever, chills, cough, and body aches. Although most people are ill for only a few days some may have secondary infections, such as pneumonia, and may need to be hospitalized. Dubuque County, lowa 3.114 Multi-jurisdictional Hazard Mitigation Plan 2018 Anyone can get influenza, but it is typically more serious in the elderly and people with chronic illnesses such as cancer, emphysema, or diabetes or weak immune systems. It is estimated that thousands of people die each year in the United States from flu or related complications. In 2011, influenza and pneumonia combined was the 8'h leading causes of death in lowa with 657 deaths. In 2008, there were over 800 influenza/pneumonia deaths. See Table 3.47 under Previous Occurrence for the number of deaths and rate from 2002-2014. Pandemic Influenza A pandemic is a global disease outbreak. A pandemic flu is a human flu that causes a global outbreak, or pandemic, of serious illness. A flu pandemic occurs when a new influenza virus emerges for which people have little or no immunity, and for which there is no vaccine. This disease spreads easily person-to-person, causing serious illness, and can sweep across the country and around the world in a very short time. The Centers for Disease Control and Prevention (CDC) has been working closely with other countries and the World Health Organization to strengthen systems to detect outbreaks of influenza that might cause a pandemic and to assist with pandemic planning and preparation. During 2009 and 2010, health professionals around the globe worked to combat the H1 N1 influenza virus. This relatively mild and stable influenza virus circulated across the globe and caused one of the most robust worldwide vaccination campaigns since the 1970s. Health professionals continue to monitor the possibility of an avian (bird) flu pandemic associated with a highly pathogenic avian H5N1 virus. Since 2003, avian influenza has been spreading through Asia. A growing number of human H5N1 cases contracted directly from handling infected poultry have been reported in Asia, Europe, and Africa, and more than half the infected people have died. There has been no sustained human-to-human transmission of the disease, but the concern is that H5N1 will evolve into a virus capable of human-to-human transmission. An especially severe influenza pandemic could lead to high levels of illness, death, social disruption and economic loss. Impacts could range from school and business closings to the interruption of basic services such as public transportation, health care, and the delivery of food and essential medicines. Pandemics are generally thought to be the result of novel strains of viruses. Because of the process utilized to prepare vaccines, it is impossible to have vaccine pre-prepared to combat pandemics. A portion of the human and financial cost of a pandemic is related to lag time to prepare a vaccine to prevent future spread of the novel virus. In some cases, current vaccines may have limited activity against novel strains. Dubuque County, lowa 3.115 Multi-jurisdictional Hazard Mitigation Plan 2018 Foodborne Disease There are several agents that can cause illness when consumers eat contaminated food, beverages or water. Foodborne illness (food poisoning) can also be spread person-to-person as well as from contact with animals. Table 3.46 is a list of common foodborne diseases Table 3.46.

Warninq Time Score: 2-12-24 hours Duration Score: 4—More than 1 week Geographic Location/6ctent A human disease outbreak has no geographic boundaries. Because of our highly mobile society, disease can move rapidly through a school, business and across the nation within days, weeks or months. Many of the infectious diseases that are designated as notifiable at the national level result in serious illness if not death. Some are treatable, for others only the symptoms are treatable. Previous Occurrences The World Health Organization tracks and reports on epidemics and other public health emergencies through the Global Alert and Response (see historic epidemics at www.who.inUen/). There have been four acknowledged pandemics in the past century: • 2009 H1N1 Influenza—The 2009 H1 N1 Pandemic Influenza caused 659 hospitalizations with lab confirmed H1 N1 since 9/1/09 and resulting in 41 fatalities. Typically, people who Dubuque County, lowa 3.116 Multi-jurisdictional Hazard Mitigation Plan 2018 became ill were the elderly, the very young and people with chronic medical conditions and high-risk behaviors. • 1968-69 Hong Kong flu (H3N2) —This strain caused approximately 34,000 deaths in the United States and more than 700,000 deaths worldwide. It was first detected in Hong Kong in early 1968 and spread to the United States later that year. Those over age 65 were most likely to suffer fatal consequences. This virus returned in 1970 and 1972 and still circulates today. • 1957-58 Asian flu (H2N2) —This virus was quickly identified because of advances in technology, and a vaccine was produced. Infection rates were highest among school children, young adults and pregnant women. The elderly had the highest rates of death. A second wave developed in 1958. In total, there were about 70,000 deaths in the United States. Worldwide deaths were estimated between one and two million. • 1918-19 Spanish flu (H1N1) —This flu is estimated to have sickened 20-40 percent of the world's population. Over 20 million people lost their lives. Between September 1918 and April 1919, 500,000 Americans died. The flu spread rapidly; many died within a few days of infection, others from secondary complications. The attack rate and mortality was highest among adults 20-50 years old; the reasons for this are uncertain.

In the last century, there have been four pandemic flu events. With the swine flu (H1 N1) outbreak in 2009-2010 within the last 10 years), the HMPC determined the possibility of a human disease outbreak causing a threat to the general public to be "Occasional", with between 10% and 20% probability of occurring. Probabilitv Score: 2—Occasional Vulnerabilitv Overview Although infectious diseases do not respect geographic boundaries, several populations in Dubuque County are at specific risk to infectious diseases. Communicable diseases are most likely to spread quickly in institutional settings such as nursing home facilities, day care facilities, and schools. There are 7 facilities that are classified as nursing homes or long-term care. There are also over 40 school facilities in the county. According to the lowa Department of Public Health —2015 Immunization Program Audit Report The 2-year-old county immunization rate for the 4-3-1-3-3-1-4 series (4 DTaP, 3 Polio, 1 MMR, 3Hib, 3 Hep B, 1 Varicella, 4 PCV by 24 months of age was 45 percent while the adolescent, 13-15-year-old, county immunization rate for the 3-1-2-1-2 (3 Hep B, 1 Meningococcal, 2 MMR, 1 Td or Tdap, 2 Varicella) series) was 31 percent (see Figure 3.25) Dubuque County, lowa 3.118 Multi-jurisdictional Hazard Mitigation Plan 2018 Figure 3.25.

The magnitude of an infectious disease outbreak is related to the ability of the public health and medical communities to stop the spread of the disease. Most disease outbreaks that cause critical numbers of deaths are communicable in nature, meaning that they are spread from person to person. The key to reducing the critical nature of the event is to stop the spread of disease. This is generally done in three ways: (1) identification and isolation of the ill, (2) quarantine of those exposed to the illness to prevent further spread, and (3) education of the public about methods to prevent transmission. The public health and health care providers in Dubuque County routinely utilize all three methods to reduce morbidity and mortality from infectious disease. Maqnitude Score: 3�ritical Potential Losses to E�cisting Development According to The Annual lmpact of Seasonal lnfluenza in the US: Measuring Disease Burden and Costs by Molinari et al., nationally the economic burden of influenza medical costs, medical costs plus lost earnings, and the total economic burden was $10.4 billion, $26.8 billion and $87.1 billion respectively. The financial burden of healthcare-associated infections nationally has been estimated at $33 billion annually. Specific amounts for Dubuque County are not available. The pandemic predictions for lowa from the lowa Pandemic lnfluenza Annex, 2006 are that 15- 35 percent of the population may be affected with a "medium level" case scenario with no vaccine and no antiviral drugs could cause 900-2,000 deaths and 3,000-7,000 hospitalizations statewide. Also, the predictions state that if a pandemic were to occur, it is likely that it would not be a worst-case scenario. Most agricultural-related jobs could continue and school and other congregating activities could be cancelled, resulting in less spreading of a disease outbreak. The U.S. Centers for Disease Control and Prevention (CDC) estimates 76 million people suffer foodborne illnesses each year in the United States, accounting for 325,000 hospitalizations and more than 5,000 deaths. Foodborne disease is extremely costly. Health experts estimate that the yearly cost of all foodborne diseases in this country is $5 to $6 billion in direct medical ex- penses and lost productivity. Infections with the bacteria Salmonella alone account for$1 billion yearly in direct and indirect medical costs. Buildings, infrastructure, and critical facilities are not vulnerable to this hazard. It affects only persons susceptible to the illness. The impacts and potential losses are largely economic and are dependent on the type, extent and duration of the illness. Future Development The population in Dubuque County has increased 2.4% in the last 5 years. About 15 percent of the population is over 65 years old. Those over 65 are more susceptible to health complications as a result of disease. Climate Change lmpacts The following is an excerpt from the 2010 Climate Change lmpacts on lowa Report. Dubuque County, lowa 3.120 Multi-jurisdictional Hazard Mitigation Plan 2018 lnvestigations of the past fwo decades indicate that the health effects of climate change can be serious. The World Health Organization estimated that in 2002, 2.4% of worldwide diarrhea cases, 6% of malaria cases, 7% of dengue fever cases, and 170,000 deaths(0.3% of worldwide deaths) were attributed to climate change (Beggs and Bambrick 2005, WHO 2002). A major 2010 study included a range of diseases in its listing of potential effects of climate change, ranging from obvious i//nesses such as asthma and vector-borne disease to /ess obvious cancer and neurological disease (Portier 2010). The report details the following as climate change contributors to negative consequences for public health in lowa: • Extreme Precipitation Events, Rising Humidity, and Associated Disease • Illness and Death Associated with Extreme Heat and Heat Waves • Warming, Air Quality and Respiratory Problems • Pollen Production and Allergies • Diseases Transferred by Food, Water, and Insects Human Disease Hazard Summary by Jurisdiction Due to disease spreading more quickly in areas with higher population density, the cities with a population over 2,000 were given a magnitude of 3. School districts were also given a magnitude of three since disease tends to spread rapidly in school settings. The unincorporated county and cities with smaller populations were given a magnitude of 2. The rest of the elements are not varied across jurisdictions.

Failure of utilities or other components of the infrastructure in the planning area can seriously impact public health, functioning of communities and the economy. Disruption of any of these services could result from the majority of the natural, technological, and manmade hazards described in this plan. In addition to a secondary or cascading impact from another primary hazard, utilities and infrastructure can fail as a result of faulty equipment, lack of maintenance, degradation over time, or accidental damage such as damage to buried lines or pipes during excavation. To maintain consistency with the state plan, this hazard encompasses a variety of different types of infrastructure failure, including communications failure, energy failure, structural failure, and structural fire. Communications Failure Communications failure is the widespread breakdown or disruption of normal communication capabilities. This could include major telephone outages, internet interruption, loss of cellular telephone service, loss of local government radio facilities, long-term interruption of electronic broadcast services, or emergency 911. Law enforcement, fire, emergency medical services, public works, and emergency warning systems are just a few of the vital services which rely on communications systems to effectively protect citizens. In addition, business and industry rely heavily on various modes of communication. Mechanical failure, traffic accidents, power failure, line severance, and weather can all affect communications systems and disrupt service. Disruptions and failures can range from localized and temporary to widespread and long-term. The types of hazards and impacts to internet and telecommunications infrastructure are very similar to electric power supply. Land line phone lines often utilize the same poles as electric lines. So, when weather events such as windstorm or winter weather cause lines to break, both electricity and telephone services experience outages. With the increasing utilization of cellular phones, hazard events such as tornado that can damage cellular repeaters can cause outages. In addition, during any hazard event, internet and telecommunications systems can become overwhelmed due to the surge in call/usage volume. Enerqv Failure Energy failure includes interruption of service to electric, petroleum, or natural gas. Disruption of electric power supply can be a cascading impact of several other hazards. Electric power is the type of energy failure that is most often a secondary impact of other hazard events. The Dubuque County, lowa 3.122 Multi-jurisdictional Hazard Mitigation Plan 2018 most common hazards analyzed in this plan that disrupt power supply are: flood, tornado, windstorm, and winter weather as these hazards can cause major damage to power infrastructure. To a lesser extent, extreme temperatures, dam failure, lightning, and terrorism can disrupt power. Extreme heat can disrupt power supply when air conditioning use spikes during heat waves which can cause brownouts. Dam failure is similar to flood in that infrastructure can be damaged or made inaccessible by water. Lightning strikes can damage substations and transformers, but is usually isolated to small areas of outage. Many forms of terrorism could impact power supply either by direct damage to infrastructure or through cyber- terrorism targeting power supply networks. Primary hazards that can impact natural gas and oil pipelines are earthquake, expansive soils, land subsidence, landslide, and terrorism. Other Utilitv Failure Interruption of other utilities such as water and sewer systems can be a devastating, costly impact. The primary hazards that can impact water supply systems are: drought, flood, hazardous materials, and terrorism. Winter storm can also impact water supply if low temperatures cause failure/breakage of water infrastructure. The primary hazard that impacts sewer systems is flood. Structural Failure / Structure Fire The collapse (partial or total) of any structure including roads, bridges, towers, and buildings is considered a structural failure. A road, bridge, or building may collapse due to the failure of the structural components or because the structure was overloaded. Natural events such as heavy snow may also cause the roof of a building to collapse (under the weight of snow). In 1983 a KVWVL television tower collapsed due to ice buildup. Heavy rains and flooding can undercut and washout a road or bridge. This occurred twice in 2008 when railway bridges failed in Waterloo and Cedar Rapids due to flooding. The age of the structure is sometimes independent of the cause of the failure. Enforcement of building codes can better guarantee that structures are designed to hold-up under normal conditions. Routine inspection of older structures may alert inspectors to weak points. The level of damage and severity of the failure is dependent on factors such as the size of the building or bridge, the number of occupants of the building, the time of day, day of week, amount of traffic on the road or bridge, and the type, and amount of products stored in the structure. There have been structural failures across the state in the past as mentioned above. They have included homes, commercial structures, and communications towers. There is no central collection point for this information, but news articles document infrastructure failure. A structural fire is an uncontrolled fire in a populated area that threatens life and property and is beyond normal day-to-day response capability. Structural fires present a far greater threat to life and property and the potential for much larger economic losses. Modern fire codes and fire suppression requirements in new construction and building renovations, coupled with improved fire-fighting equipment, training, and techniques lessen the chance and impact of a major urban fire. Most structural fires occur in residential structures, but the occurrence of a fire in a commercial or industrial facility could affect more people and pose a greater threat to those near Dubuque County, lowa 3.123 Multi-jurisdictional Hazard Mitigation Plan 2018 the fire or fighting the fire because of the volume or type of the material involved. Less severe structural fires are almost a common occurrence in some communities.

For specific descriptions, please see the Previous Occurrences section of the other hazards included in this plan. In addition to failure/impacts as a result of other hazard events, Infrastructure Failure can also occur as a result of lack of maintenance, human error, and age deterioration. Dubuque County, lowa 3.129 Multi-jurisdictional Hazard Mitigation Plan 2018 The structural fires that have occurred in Dubuque County have been within the normal day-to- day response capability, including use of pre-arranged mutual aid and do not fall into the category of uncontrolled fires in a populated area that threatens life and property. Probability of Future Occurrences As discussed in other hazard sections in this plan, infrastructure failure occurs as a secondary or cascading impact from several primary hazards such as winter storm, wind storm, and tornado as well as lack of maintenance and age deterioration and other human-caused incidents such as human error, and various forms of terrorism. Structure fire events also occur annually. Therefore, the HMPC determined the probability of future occurrence of this hazard to be "Highly likely". Probabilitv Score: 4—Highly Likely Vulnerabilitv Vulnerability Overview lowa is almost entirely dependent on out-of-state resources for energy. lowans purchase oil, coal, and natural gas from outside sources. As a result, world and regional fuel disruptions are felt in lowa. Every community in the planning area is at risk to some type of utility/infrastructure failure. Business and industry in the urban areas are reliant on electricity to power servers, computers, automated systems, etc. Rural areas of the County are vulnerable as well, as modern agricultural practices are reliant on energy; such as electric milking machines and irrigation pivots. Generally, the smaller utility suppliers such as small electrical suppliers have limited resources for mitigation. This could mean greater vulnerability in the event of a major, widespread disaster, such as a major flood, severe winter storm or ice storm. The municipal utilities that exist in the County purchase power on the wholesale market for resale to their customers. This may make them more vulnerable to regional shortages of power as well. In the event of a large-scale event impacting water supply or wastewater treatment homes and businesses with, well-supplied water and septic systems for waste treatment would be largely unaffected. However, these systems may be prone to individual failure and do not have back- up systems in place in the event of failure as larger systems might.

Dubuque County has seen an overall population decrease of about 2.4 percent in the last five years. As technological advances are made and systems become more and more automated and dependent on power and communications infrastructure, the impacts of infrastructure failure could increase even though population is decreasing slightly.

The basic ingredients for landslides are gravity, susceptible soil or rock, sloping ground and water. Landslides occur when susceptible rock, earth, or debris moves down a slope under the force of gravity and water. Landslides may be very small or very large and can move at slow to very high speeds. A natural phenomenon, small scale landslides have been occurring in slide-prone areas of lowa long before human occupation. New landslides can occur because of rainstorms, fires, earthquakes and various human activities that modify slope and drainage. Warninq Time Score: 2-12 to 24 hours warning time Duration Score: 1—Less than 6 hours Geographic Location/6ctent Dubuque County, including the City of Dubuque is located on the bluff lands of the Mississippi River Valley, which falls into the area for potential landslides. The planning committee noted landslides in the County in the areas of: Park Hollow, Heritage Trail and Highway 52. The events are infrequent and are not considered to be of significant concern. However, as development continues to occur on the high bluffs surrounding the banks of the Mississippi River and other areas where high embankments exist within the city limits, the city continues to witness occasional landslide events at various locations around the city. The City has an active inspection program which monitors construction activities and associated erosion control measures on a quarterly basis and after heavy rainfall events. A part of these activities includes the inspector being cognizant of possible landslides due to construction or other activities in the area. Another area of concern for the City of Dubuque is retaining walls. Development of the City of Dubuque has included many retaining walls over the years. Many of the walls are on private property either along the street right-of-way line or between lots. Some retaining walls have been constructed along the right-of-way in order to allow for the construction of the street. Surface runoff and subsurface water occasionally cause movement in the wall or stones being displaced. The City relies on maintenance workers and the general public to keep abreast of any changes in the structural stability of the walls. When notification of minor movement in the wall is received, after examination, City Engineering may set up control points to monitor the movement. If the wall is an immediate hazard, the area of influence will be barricaded off to protect the public. The wall will then be examined for corrective action or reconstruction. Since there are a number of retaining walls that are considered public, the City has an annual Capital Improvement Project budget for such repairs or reconstruction.

Dubuque County, lowa 3.134 Multi-jurisdictional Hazard Mitigation Plan 2018 Previous Occurrences Both the Unincorporated County and the City of Dubuque noted that landslides have occurred. There is no specific record of landslide incidents and these jurisdictions reported that they occur infrequently. Probability of Future Occurrence The HMPC determined the probability of future occurrence of landslide in the planning area to be "Occasional". Probabilitv Score: 2-0ccasional Vulnerabilitv Vulnerability Overview There will continue to be intense rainfall events that may cause landslides in the planning area. But, the damages are relatively minimal and not widespread. Maqnitude Score: 1—Negligible Potential Losses to E�cisting Development Due to the lack of information regarding previous occurrences of this hazard, it is not possible to estimate potential losses. Future Development Future development down slope from areas prone to landslide will increase vulnerability to this hazard. Climate Change lmpacts One of the climate change impacts noted in the 2010 Climate Change lmpacts on lowa report by the lowa Climate Change Impacts Committee is the increase in frequency of severe precipitation events. See the "Climate Change Impacts" discussion in the Flash Flood Hazard Section (3.5.6) Dubuque County, lowa 3.135 Multi-jurisdictional Hazard Mitigation Plan 2018 Landslide Hazard Summary by Jurisdiction The probability for Dubuque County and the City of Dubuque was determined to be 2- Occaisonal. Since the other jurisdictions did not report issues with landslides, they received a probability rating of 1-Unlikely. Other elements do not vary.

Radiological incidents related to transportation are described as an incident resulting in a release of radioactive material during transportation. Transportation of radioactive materials through lowa over the interstate highway system is considered a radiological hazard. The transportation of radioactive material by any means of transport is licensed and regulated by the federal government. As a rule, there are two categories of radioactive materials that are shipped over the interstate highways: 1. Low level waste consists of primarily of materials that have been contaminated by low level radioactive substances, but pose no serious threat except through long term exposure. These materials are shipped in sealed drums within placarded trailers. The danger to the public is no more than a wide array of other hazardous materials. 2. High level waste, usually in the form of spent fuel from nuclear power plants, is transported in specially constructed casks that are built to withstand a direct hit from a locomotive. Warninq Time Score: 4—less than six hours warning time Duration Score: 4—More than 1 week Geographic Location/6ctent Fixed Facilities An incident resulting in a release of radiological material at a fixed facility is a fixed radiological incident. There is one nuclear power plant located within lowa: the Duane Arnold Energy Center near Palo in Linn County. There are three additional nuclear facilities in adjacent states with planning buffer zones that cross into lowa: Ft. Calhoun Nuclear Power Plant north of Omaha, Nebraska, Cooper Nuclear Power Plant south of Nebraska City, Nebraska, and Quad Cities Nuclear Power Plant in Cordova, Illinois. The southeast corner of Dubuque County is in the 50-mile planning buffer of the Quad Cities Nuclear Power Plant and the western side of Dubuque County is in the 50- mile planning buffer of the Duane Arnold Energy Center (see Figure 3.30) Dubuque County, lowa 3.137 Multi-jurisdictional Hazard Mitigation Plan 2018 Figure 3.30.

Transportation Radiological lncidents There is also potential for the transport of radioactive waste within Dubuque County. Previous Occurrences The U.S. Nuclear Regulatory Commission has emergency classifications divided into four categories. Each level has a certain response requirement from the plant and government. The following are the emergency classifications from least to most severe: • Unusual Event • Alert • Site Area Emergency • General Emergency Dubuque County, lowa 3.138 Multi-jurisdictional Hazard Mitigation Plan 2018 From 1990 to 2013, the following emergency classifications have occurred for the Quad Cities and Duane Arnold Nuclear Power Plants: • The Quad Cities Nuclear Power Plant has had 18 Unusual Events, 7 Alerts, and no Site Area Emergencies or General Emergencies. • The Duane Arnold Energy Center has had 7 Unusual Events, 1 Alert, and no Site Area Emergencies or General Emergencies. According to the lowa State Hazard Mitigation Plan, 2013, there have been no occurrences of a radiological transportation incident in lowa since 1990. Probability of Future Occurrence The Nuclear Regulatory Commission (NRC) regulates commercial nuclear power plants and other uses of nuclear materials through licensing, inspection, and enforcement of requirements. Within the NRC, several OFfices and Divisions have various responsibilities to ensure nuclear power plant safety. The Office of Nuclear Reactor Regulation is responsible for accomplishing key components of the NRC's nuclear reactor safety mission. As such, NRR conducts a broad range of regulatory activities in the four primary program areas of rulemaking, licensing, oversight and incident response for commercial nuclear power reactors, and test and research reactors to protect the public health, safety and the environment. NRR works with the regions and other offices to accomplish its mission and contribute to the agency mission. Additionally, the Radiological Emergency Preparedness (REP) Program within FEMA coordinates the national effort to provide state, local and tribal governments with relevant and executable planning, training, and exercise guidance and policies necessary to ensure that adequate capabilities exist to prevent, protect against, mitigate the effects of, respond to, and recover from incidents involving commercial nuclear power plants. Dubuque County Emergency Management works closely with the REP program to ensure preparedness for any incidents involving the nuclear power plants. Considering the regulatory and preparedness programs in place and based on the lack of any Site Area or General Emergency previous occurrences for this hazard, the probability of future occurrences of radiological incidents is "Unlikely". Probabilitv Score: 1—Unlikely Vulnerabilitv Vulnerability Overview In general, danger to the public in the planning area is less than a wide array of other hazardous materials. Those working with or near sources of radiation are at a greater risk than the general citizens in the planning area. Those responding to a radiological incident should be trained in recognizing a radiological incident and minimize exposure to radioactive materials. Although the probability of occurrence is low, if a release of radiation from the nuclear power plants did occur, this could have serious consequences in Dubuque County. Even if health impacts were not evident, the number of worried well could flood available healthcare facilities. Dubuque County, lowa 3.139 Multi-jurisdictional Hazard Mitigation Plan 2018 Maqnitude Score: 4�atastrophic Potential Losses to E�cisting Development Responding to the effects of a radiological incident in the planning area would be extensive and would require resources and assistance from several state and federal agencies to determine and evaluate the threat to life and the environment. Due to the variable nature of this hazard, it is not possible to quantify potential losses. Future Development Increased development in the planning buffer zones and along transportation corridors would increase the number of people vulnerable to this hazard in the planning area. Climate Change lmpacts Drought can impact water levels for intake pipes that carry water from the Mississippi River to cool the reactor. See Section 3.5.3 for discussion of Climate Change Impacts for Drought. Radiological lncident Hazard Summary by Jurisdiction The southeast corner of Dubuque County is in the 50-mile planning buffer of the Quad Cities Nuclear Power Plant and the western side of Dubuque County is in the 50- mile planning buffer of the Duane Arnold Energy Center Although an incident is unlikely, the following jurisdictions within the planning area are at risk to this hazard: Unincorporated County, Bankston, Bernard, Cascade, Dyersville, Epworth, Farley, Holy Cross, Luxemburg, New Vienna, Worthington, and Western Dubuque CSD. The magnitude for these jurisdictions was considered to be 4-Critical. Although the other jurisdictions are outside the planning buffer, they are still in close proximity and would most likely have negative impacts as well. The magnitude for these jurisdictions was considered to be 2-Limited. No other elements vary.

A flood is partial or complete inundation of normally dry land areas. Heavy precipitation can cause flooding either in the region of precipitation or in areas downstream. Heavy accumulations of ice or snow can also cause flooding during the melting stage. These events are complicated by the freeze/thaw cycles characterized by moisture thawing during the day and freezing at night. There are two main types of flooding in the planning area: riverine flooding and flash flooding which includes ice jam flooding. Flash flooding is discussed separately in Section 3.5.6. A specific type of flash flooding can occur as a result of dam failure or levee failure. Flooding caused by dam or levee failure is discussed in Section 3.5.2 Riverine flooding is defined as the overflow of rivers, streams, drains and lakes due to excessive rainfall, rapid snowmelt or ice melt. The areas adjacent to rivers and stream banks that carry excess floodwater during rapid runoff are called floodplains. A floodplain is defined as the lowland and relatively flat area adjoining a river or stream. The terms "base flood" and "100- year flood" refer to the area in the floodplain that is subject to a one percent or greater chance of flooding in any given year. Floodplains are part of a larger entity called a basin, which is defined as all the land drained by a river and its branches. Gauges along streams and rain gauges throughout the state provide for an early flood warning system. River flooding usually develops over the course of several hours or even days depending on the basin characteristics and the position of the particular reach of the stream. The National Weather Service provides flood forecasts for lowa. Flood warnings are issued over emergency radio and television messages as well as the NOAA Weather Radio. People in the paths of river floods may have time to take appropriate actions to limit harm to themselves and their property. Warninq Time Score: 1—More than 24 hours warning time Duration Score: 4—More than 1 week Dubuque County, lowa 3.141 Multi-jurisdictional Hazard Mitigation Plan 2018 Geographic Location/6ctent The Mississippi River provides the eastern boundary for Dubuque County. Other major rivers in the county include Caffish Creek, South Fork, Middle Fork, North Fork Caffish Creeks and the Little Maquoketa river. Numerous small creeks, branches of rivers, and streams also flow through the County. Flooding from these rivers and their tributaries has been a significant problem for several of the communities in Dubuque County. There are four HUC-8 watersheds in Dubuque County (see Figure 3.31): • Grant-Little Maquoketa, 0706003 • Turkey, 0706004 • Apple-Plum, 07060005 • Maquoketa, 07060006 Figure 3.31.

Presidential Declarations for Floodinq in Planninq Area Since 1965 there have been 15 Major Presidential Disaster Declarations that included flooding in the planning area. The only disaster declaration during this time period did not include flooding was the 2005 Emergency Declaration for evacuees entering the state due to Hurricane Katrina. Additional details of the flood-related disaster declarations are provided in Table 3.2 in the Hazard Identification Section. According to the National Climatic Data Center, there were 14 reported flood events from 1993- 2016. Please note: events reported less than 10 days apart were combined and counted as one event. Details are provided below in Table 3.53. Table 3.53.

The City of Durango reported heavy downpours, thunder and lightning. According to the planning committee, water entered the City of Durango from several sources. Water came over Highway 52 and the worst came from the north, from the area around the City of Sherrill and "raged" down highway 52. As water came over the highway, it poured into doors and into homes. Three of the creeks that run through Durango have reportedly filled with sediment and floods have deposited soil. This has resulted in the waterways not being as deep or wide as they once were; consequently, flooding occurs more often and to a greater extent. • Dubuque: Historically, the Mississippi River has flooded the City of Dubuque's low-lying riverfront properties many times over the last 150 years. As the result of a concerted effort by local, state, and federal officials to construct a protective levee system was initiated. The 6.4-mile-long earthen and concrete floodwall system was completed in 1973. This system has protected Dubuque from numerous Mississippi River flood events since its completion including four of the ten highest flood crests ever measured, one of these was Dubuque's second highest ever crest of 25.40 feet in 2001. Although most of the city of Dubuque is protected by the levee system, Chaplain Schmitt Island and Catfish Creek valley lie outside the protected area. • Dyersville: The city of Dyersville has a long history of dealing with flood events. The area experienced major flooding in 1999 and 2002 that prompted the first of several grant applications to acquire floodprone properties. To date, all of the properties targeted for acquisition have either been acquired or withdrawn. Previous Aqricultural Impacts Flooding and excess moisture take a toll on crop production in the planning area. According to the USDA's Risk Management Agency, payments for insured crop losses in the planning area as a result of excess moisture and flood conditions from 2007-2016 totaled $13,985,489. This translates to an annual average of$1,398,549. According to USDA Risk Management Agency's 2015 lowa Crop Insurance Profile, 89 percent of insurable crops in lowa were insured. Table 3.54 summarizes the claims paid by year. Table 3.54.

According to NCDC, in the 24-year time-frame from 1993-2016, there were 14 events (multiple events less than 10 days apart counted as one event). This translates to a 58 percent annual probability. Therefore, the probability rating is "Highly Likely". Probabilitv Score: 4—Highly Likely Dubuque County, lowa 3.170 Multi-jurisdictional Hazard Mitigation Plan 2018 Vulnerabilitv To determine vulnerability of people and property to riverine flood, an enhanced flood risk analysis was performed utilizing FEMA's Hazus software. This analysis included Level 2 enhancements to both the hazard and inventory inputs to the Hazus model to enhance the accuracy of flood risk modeling as follows: • Depth Grids provided by the University of lowa's lowa Flood Center (IFC) • Parcel layer provided by Dubuque County • Assessor's data, including assessed valuations and other building attributes provided by Dubuque County The Depth Grids provided by the IFC were used as the best available data to import into Hazus since older FEMA depth grids are difficult to obtain, if they exist, and using the IFC data complements the efforts that the lowa Homeland Security and Emergency Management Department is undertaking for the State Plan. It should be noted that the lowa Flood Center depth grids are very similar to the effective FEMA products; however, there are some differences in the detailed areas for the 1-percent annual chance floodplain. Default Hazus inventories for structures were replaced with data supplied by Dubuque County utilizing the parcel layer and additional structure attributes in the Assessor's data. GIS was used to create a centroid, or point, representing the center of the parcel polygon in the parcel layer to represent the location of the primary structure on each parcel. The structure inventory data set was formatted for use in Hazus using the Hazus Comprehensive Data Management System (CDMS) tool. This tool syncs data and attributes fields necessary for Hazus analysis and imports the enhanced data set into the Hazus study region. After the hazard and inventory data was imported into Hazus, analysis was completed to determine the potential losses as a result of a 1-percent annual chance flood. The portions of Cascade, Dyersville, and Zwingle that extend into adjacent counties were included in this analysis. Both Cascade and Dyersville did have parcels in adjacent counties that intersect the depth grid floodplain. However, Zwingle did not. The flowing jurisdictions would have losses as a result of a 1-percent annual chance flood: Cascade, Dubuque, Durango, Dyersville, Graf, New Vienna, Peosta, Sageville, Worthington, Zwingle, and the Unincorporated County. There are otherjurisdictions in the planning area that have Special Flood Hazard Areas, but no parcels with improvements intersected with the depth grid floodplain. These include: Asbury, Bernard, Epworth, Farley, Luxemburg, and Rickardsville. Finally, the following jurisdictions do not have any Special Flood Hazard areas: Balltown, Bankston, Centralia, Holy Cross, and Sherrill. The most losses would occur in Dyersville, followed by the unincorporated county, Sageville and Dubuque, Dubuque County, lowa 3.171 Multi-jurisdictional Hazard Mitigation Plan 2018 For the planning area ranking, the HMPT determined the magnitude of river flooding to be "Critical". Individual jurisdictional ratings are provided at the end of this hazard section. Maqnitude Score: 2—Critical Potential Losses to E�cisting Development The potential losses to existing development will be provided for the following categories of losses: • Building/Property Losses; • Estimated Population Displaced; • Agricultural Impacts; and • Critical Facilities and Infrastructure at Risk. Building/Contents Losses Table 3.57 provides the summary of potential flood loss estimates for the 1-percent annual chance flood by jurisdiction based on the Hazus Level 2 Analysis described in the Overview section above. It should be noted that there was a total of 383 out of a total 497 parcels that intersect the depth grid floodplain that did not result in calculated losses. The Hazus Helpdesk was contacted about this anomaly. However, no resolution has been achieved. Dubuque County, lowa 3.172 Multi-jurisdictional Hazard Mitigation Plan 2018 Tahle 3.57.

This analysis included all residential structures in the risk area, not just those that indicated losses. According to the analysis, there would be a total of 293 residential structures at risk. Table 3.58 provides the estimated population impacted for each jurisdiction with parcels that intersected the depth grid floodplain. According to this analysis, nearly 700 people could be displaced.

Considering that 89 percent of insurable crops are insured in lowa (2015 lowa Crop Insurance Profile, USDA, RMA), the adjusted losses calculate to $15,714,033 for all insurable crops for the period. This results in an average annual loss estimate of $1,571,403 to insurable crops as a result of excess moisture/precipitation/rain and flood conditions affecting agriculture. Critical Facilities and Infrastructure at Risk To analyze critical facilities at risk in the planning area, the inventory of critical and essential facilities and infrastructure in the planning area was compiled from data layers provided by Dubuque County. A comparison was made of the 429 total critical facilities with the effective flood insurance rate map to determine those facilities that would be damaged in the 1-percent and 0.2-percent annual chance flood events. This analysis determined that there are 17 critical facilities in the 1-percent annual chance floodplain and 4 critical facilities in the 0.2-percent annual chance floodplain. Table 3.59 provides a summary of the critical facilities in the 1- percent annual chance floodplain. Additional details, including specific structure names and addresses as well as details on the 4 facilities in the 0.2-percent annual chance floodplain are provided in Appendix E.

HffLD National Bridge Invenrory 201] Future Development Any future development in floodplains would increase risk in those areas. For those communities that participate in the National Flood Insurance Program, enforcement of the floodplain management regulations will ensure mitigation of future construction in those areas. With new regulatory flood maps in process of becoming effective, additional communities with designated Special Flood Hazard Areas are intending to join the National Flood Insurance Program, including regulation of development in their floodplains. Gimate Change Impacts One of the climate change impacts noted in the 2010 Climate Change Impacts on lowa report by the lowa Climate Change Impacts Committee is the increase in frequency of severe precipitation events. This climate change impact was also noted in the Flash Flood hazard analysis. Although very heavy precipitation does not always result in riverine flooding, it can if/when the very heavy precipitation occurs frequently without enough time for the watershed to drain away as much water is coming in due to precipitation in the watershed or upstream watersheds. Figure 3.17 in the Flash Flood section shows that all of lowa is in the region with a 31% increase in very heavy precipitation from 1958 to 2007. For this study, very heavy precipitation Dubuque County, lowa 3.177 Multi-jurisdidional Hazard Mitigation Plan 2018 was defined as the heaviest 1% of all events. If this trend increases, riverine flooding events and their associated impacts will likely occur more often in the planning area. River Flooding Hazard Summary by Jurisdiction To demonstrate how river flooding varies additionally by jurisdiction, all jurisdictions that had any structural improvements in the 1-percent annual chance floodplain received a rating of 4 for probability. Magnitude for the county and incorporated cities was based on the number of structures in the floodplain. Jurisdictions with less than 5 structures in the floodplain received a magnitude of negligible (1), 5 up to less than 20 received a magnitude of limited (2) and more than 20 structures in the floodplain received a magnitude of critical (3). For jurisdictions with designated floodplain areas, but no parcels with improvements in the floodplain, both probability and magnitude were determined to be 1 — unlikely and 1-negligible, respectively. For those jurisdictions with no Special Flood Hazard Areas, all elements indicate Not Applicable (N/A) unless other specific infrastructure has been identified as vulnerable in the floodplain. To determine the rankings for the school districts, the critical facility layer of school buildings was compared against the Flood Insurance Rate Map. This analysis revealed two schools in the 1- percent annual chance floodplain, the St. Francis Xavier School in Dyersville and the Bernard Elementary School in the unincorporated county, both part of the Western Dubuque School District. The warning time and duration were considered to be 1 and 4 for all jurisdictions to which the flood hazard applies.

A major winter storm can last for several days and be accompanied by high winds, freezing rain or sleet, heavy snowFall, cold temperatures and drifting snow creating blizzards. The National Weather Service describes different types of winter storm events as follows: • Blizzard—Winds of 35 mph or more with snow and blowing snow reducing visibility to less than Ya mile for at least three hours. • Blowing Snow—Wind-driven snow that reduces visibility. Blowing snow may be falling snow and/or snow on the ground picked up by the wind. • Snow Squalls—Brief, intense snow showers accompanied by strong, gusty winds. Accumulation may be significant. • Snow Showers—Snow falling at varying intensities for brief periods of time. Some accumulation is possible. • Freezing Rain—Measurable rain that falls onto a surface with a temperature below freezing. This causes it to freeze to surfaces, such as trees, cars, and roads, forming a coating or glaze of ice. Most freezing-rain events are short lived and occur near sunrise between the months of December and March. • Sleet—Rain drops that freeze into ice pellets before reaching the ground. Sleet usually bounces when hitting a surface and does not stick to objects. Heavy accumulations of ice, often the result of freezing rain, can bring down trees, utility poles, and communications towers and disrupt communications and power for days. Even small accumulations of ice can be extremely dangerous to motorists and pedestrians. Severe winter storms include extreme cold, heavy snowFall, ice, and strong winds which can push the wind chill well below zero degrees in the planning area. Heavy snow can bring a community to a standstill by inhibiting transportation (in whiteout conditions), weighing down utility lines and by causing structural collapse in buildings not designed to withstand the weight of the snow. Repair and snow removal costs can be significant. Ice buildup can collapse utility lines and communication towers, as well as make transportation difficult and hazardous. Ice can also become a problem on roadways if the air temperature is high enough so that precipitation falls as freezing rain rather than snow. Extreme cold often accompanies severe winter storms and can lead to hypothermia and frostbite in people who are exposed to the weather without adequate clothing protection. Cold can cause fuel to congeal in storage tanks and supply lines, stopping electric generators. Cold temperatures can also overpower a building's heating system and cause water and sewer pipes Dubuque County, lowa 3.179 Multi-jurisdictional Hazard Mitigation Plan 2018 to freeze and rupture. When combined with high winds from winter storms, extreme cold becomes e#reme wind chill, which is extremely hazardous to health and safety. The National Institute on Aging estimates that more than 2.5 million Americans are especially vulnerable to hypothermia, with the isolated elderly being most at risk. About 10 percent of people over the age of 65 have some kind of tempereture-regulating defect, and 3-4 percent of all hospital patients over 65 are hypothermic. Also at risk are those without shelter or who are stranded, or who live in a home that is poorly insulated or without heat. Other impacts of extreme cold include asph�iation (unconsciousness or death from a lack of oxygen) from toxic fumes from emergency heaters; household fres, which can be caused by freplaces and emergency heaters; and frozen/burst pipes. Wind can greatly amplify the impact of cold ambient air temperetures. Provided by the National Weather Service, Figure 3.56 below shows the relationship of wind speed to apparent tempereture and typical time periods for the onset of frostbite. Figure 3.56.

This translates to an annual probability of over 6 blizzards, winter/ice storm, or extreme cold events per year. Therefore, the probability rating is "Highly Likely". Probabilitv Score: 4—Highly Likely Dubuque County, lowa 3.182 Multi-jurisdictional Hazard Mitigation Plan 2018 Vulnerabilitv Vulnerability Overview The entire planning area is vulnerable to the effects of winter storm. Hazardous driving conditions due to snow and ice on highways and bridges lead to many traffic accidents and can impact the response of emergency vehicles. The leading cause of death during winter storms is transportation accidents. About 70 percent of winter-related deaths occur in automobiles due to traffic accidents and about 25 percent are from people caught outside in a storm. Emergency services such as police, fire and ambulance are unable to respond due to road conditions. Emergency needs of remote or isolated residents for food or fuel, as well as for feed, water and shelter for livestock are unable to be met. The probability of utility and infrastructure failure increases during winter storms due to freezing rain accumulation on utility poles and power lines. People, pets, and livestock are also susceptible to frostbite and hypothermia during winter storms. Those at risk are primarily either engaged in outdoor activity (shoveling snow, digging out vehicles, or assisting stranded motorists), or are the elderly. Schools often close during extreme cold or heavy snow conditions to protect the safety of children and bus drivers. Citizens' use of kerosene heaters and other alternative forms of heating may create other hazards such as structural fires and carbon monoxide poisoning. According to the 20131owa Hazard Mitigation Plan, of the 8 hazards for which data was available to estimate annualized losses, severe winter storm ranked 6'h with $2.2 million in annualized losses based on data spanning a 13-year period. Maqnitude Score: 2—Limited Potential Losses to E�cisting Development Vulnerable Buildinqs, Infrastructure, and Critical Facilities Buildings with overhanging tree limbs are more vulnerable to damage during winter storms. Businesses experience loss of income as a result of closure during power outages. In general, heavy winter storms increase wear and tear on roadways though the cost of such damages is difficult to determine. Businesses can experience loss of income as a result of closure during winter storms. Loss of Use Overhead power lines and infrastructure are also vulnerable to damages from winter storms, in particular ice accumulation during winter storm events can cause damages to power lines due to the ice weight on the lines and equipment as well as damage caused to lines and equipment from falling trees and tree limbs weighted down by ice. Potential losses would include cost of repair or replacement of damaged facilities, and lost economic opportunities for businesses. Secondary effects from loss of power could include burst water pipes in homes without electricity during winter storms. Public safety hazards include risk of electrocution from downed power lines. Specific amounts of estimated losses are not available due to the complexity and multiple variables associated with this hazard. Dubuque County, lowa 3.183 Multi-jurisdictional Hazard Mitigation Plan 2018 The electric power loss of use estimates provided in 0 below were calculated using FEMA's Standard Values for Loss of Service for Utilities published in the June 2009 BCA Reference Guide. These figures are used to provide estimated costs associated with the loss of power in relation to the populations in Dubuque County's jurisdictions. The loss of use estimates for power failure associated with winter storms is provided as the loss of use cost per person, per day of loss. The estimated loss of use provided for each jurisdiction represents the loss of service of the indicated utility for one day for 10 percent of the population. It is understood that in rural areas, the typical loss of use may be for a larger percentage of the population for a longer time during weather extremes. These figures do not take into account physical damages to utility equipment and infrastructure. Table 3.62.

However, damages for winter and ice storms are reported for all weather zones impacted. So, it is extremely difficult to determine the damages from these events that apply specifically to Dubuque County. USDA crop insurance claims for cold conditions and snow for the ten-year period of 2007-2016 totaled $570,327. The 2015 lowa Crop Insurance Profile from USDA, RMA shows that 89 percent of crops are insured in lowa and the adjusted losses calculate to $640,817 for the period and $64,082 in estimated annualized losses. Considering the $120 million market value of crops from the 2012 Census of Agriculture as baseline crop exposure, the estimated annual losses from cold conditions and snow was determined minimal (0.05%) compared to the value of the insurable crops. /ncreased Risk Populations Elderly populations are considered to be at increased risk to Winter Storms and associated extreme cold events. 0 in the Extreme Heat Profile Section provides the number of population over 65 in each jurisdiction in the planning area. Future Development Future development could potentially increase vulnerability to this hazard by increasing demand on the utilities and increasing the exposure of infrastructure networks. Climate Change lmpacts According to the 2010 report on Climate Change lmpacts on lowa, lowa has experienced a long-term upward trend in temperature • Long-term winter temperatures have increased six times more than summer temperatures. • Nighttime temperatures have increased more than daytime temperatures since 1970. • Since 1970, daily minimum temperatures have increased in summer and winter; daily maximum temperatures have risen in winter, but declined substantially in summer. If this trend continues, future occurrences of the extreme cold/wind chill aspects of winter storms should decrease. In addition, higher winter temperatures bring higher probability of rain, rather than snow. As a result, the amount of precipitation falling as snow should decrease. Dubuque County, lowa 3.185 Multi-jurisdictional Hazard Mitigation Plan 2018 Severe Winter Storm Hazard Summary by Jurisdiction Although crop loss as a result of winter storm occurs more in the unincorporated portions of the planning area, the crops losses are not high since corn and soybeans are not in the ground during winter months and only get affected from unusual weather events. The density of vulnerable populations is higher in the cities. Transportation incidents related to winter storm could also impact all jurisdictions. With these vulnerabilities that apply to both urban and rural jurisdictions, the magnitude of this hazard is relatively equal. The factors of probability, warning time and duration are also equal across the planning area. This hazard does not substantially vary by jurisdiction.

As the rock dissolves, void spaces and caverns develop underground. The sudden collapse of the land surface can be dramatic and range in size from broad, regional lowering of the land surface to localized collapse. Although subsidence can be a naturally occurring hazard, the primary causes of most incidents of subsidence are human activities: underground mining of coal, groundwater or petroleum withdraw, and drainage of organic soils. Land subsidence occurs slowly and continuously over time or on occasion abruptly, as in the sudden formation of sinkholes. Sinkholes can be aggravated by flooding. Karst is a landscape formed from the dissolution of soluble rocks including limestone, dolomite and gypsum. Sinkholes are a common indication of karst; caves and underground drainage systems are other indicators. With limestone commonly found in northeast lowa, sinkholes have the potential to occur. Warninq Time Score: 4—Minimal or no warning time Duration Score: 1—Less than 6 hours Geographic Location/6ctent There are three areas in lowa where large numbers of sinkholes exist: 1) within the outcrop belt of the Ordovician Galena Group carbonates in Allamakee, Clayton, and Winneshiek Counties; 2) in Devonian carbonates in Bremer, Butler, Chickasaw and particularly Floyd and Mitchell counties; and 3) along the erosional edge of silurian carbonates in Dubuque and Clayton Counties. According to the Department of Natural Resources, there are sinkholes as well as potential karst areas in Dubuque County (see Figure 3.58) Dubuque County, lowa 3.187 Multi-jurisdictional Hazard Mitigation Plan 2018 Figure 3.58.

These hazards can occur anywhere and demonstrate unlawFul force, violence, and/or threat against persons or property causing intentional harm for purposes of intimidation, coercion or ransom in violation of the criminal laws of the United States. These actions may cause massive destruction and/or extensive casualties. The threat of terrorism, both international and domestic, is ever present, and an attack can occur when least expected. Enemy attack is an incident that could cause massive destruction and extensive casualties throughout the world. Some areas could experience direct weapons' effects: blast and heat; others could experience indirect weapons' effect. International political and military activities of other nations are closely monitored by our federal government and the State of lowa would be notified of any escalating military threats. The use of biological agents against persons or property in violation of the criminal laws of the United States for purposes of intimidation, coercion or ransom can be described as biological terrorism. Liquid or solid contaminants can be dispersed using sprayers/aerosol generators or by point of line sources such as munitions, covert deposits and moving sprayers. Biological agents vary in the amount of time they pose a threat. They can be a threat for hours to years depending upon the agent and the conditions in which it exists. Agro-terrorism consists of acts to intentionally contaminate, ruin, or otherwise make agricultural products unfit or dangerous for consumption or further use. Agriculture is an important industry in lowa and Dubuque County. The introduction of a biological agent into the population of 135,000 cattle and calves, or the 137,271 hogs and pigs, or the 146,000 acres of corn in Dubuque County would be financially devastating and would have a major impact on the food supply of the state and the nation. A major attack involving the nation's food supply could be launched in a rural area that has little capacity to respond. Potential terrorists' targets for livestock disease introduction would be concentration points, such as the County's licensed feedlots or livestock markets discussed later in the Geographic Location section. Chemical terrorism involves the use or threat of chemical agents against persons or property in violation of the criminal laws of the United States for purposes of intimidation, coercion or ransom. Effects of chemical contaminants are similar to biological agents. Use of conventional weapons and explosives against persons or property in violation of the criminal laws of the United States for purposes of intimidations, coercion, or ransom is conventional terrorism. Hazard affects are instantaneous; additional secondary devices may be used, lengthening the time duration of the hazard until the attack site is determined to be clear. Dubuque County, lowa 3.191 Multi-jurisdictional Hazard Mitigation Plan 2018 The extent of damage is determined by the type and quantity of explosive. Effects are generally static other than cascading consequences and incremental structural failures. Conventional terrorism can also include tactical assault or sniping from remote locations. Electronic attack using one computer system against another in order to intimidate people or disrupt other systems is a cyber-attack. All governments, businesses and citizens that conduct business utilizing computers face these threats. Cyber-security and critical infrastructure protection are among the most important national security issues facing our country today. As such, the lowa Division of Criminal Investigation has a Cyber Crime Unit tasked with analysis and retrieval of digital information for investigations. Radiological terrorism is the use of radiological materials against persons or property in violation of the criminal laws of the United States for purposes of intimidation, coercion or ransom. Radioactive contaminants can be dispersed using sprayers/aerosol generators, or by point of line sources such as munitions, covert deposits and moving sprayers or by the detonation of a nuclear device underground, at the surface, in the air or at high altitude. Mass demonstrations, or direct conflict by large groups of citizens, as in marches, protect rallies, riots, and non-peaceful strikes are examples of public disorder. These are assembling of people together in a manner to substantially interfere with public peace to constitute a threat, and with use of unlawFul force or violence against another person, or causing property damage or attempting to interfere with, disrupting, or destroying the government, political subdivision, or group of people. Labor strikes and work stoppages are not considered in this hazard unless they escalate into a threat to the community. Vandalism is usually initiated by a small number of individuals and limited to a small target or institution. Most events are within the capacity of local law enforcement. The Southern Poverty Law Center reported in 2014 there were five active hate groups in lowa: one racist skinhead group (Aryan Strike force), three Ku Klux Klan groups (Fraternal White Knights of the KKK, Loyal White Knights of the KKK, and New Empire Knights of the KKK) and one Neo-Nazi group (National Socialist Movement). Warninq Time Score: 4—Minimal or no warning Duration Score: 4—More than 1 week Geographic Location/6ctent The entire planning area has a low potential for terrorist activity. However, any venue with a large gathering of people could be a potential target for terrorists. The most likely targets of a conventional terrorism attack in Dubuque County include public school system facilities the Dubuque County Courthouse and law enforcement centers within Dubuque County. In terms of cyber-terrorism, our society is highly networked and interconnected. An attack could be launched from anywhere on earth and could range in impacts from small and localized to a far-reaching global scale. Depending on the attack vector and parameters, a cyber-attack could impact all of Dubuque County and its associated municipal jurisdictions.

There have been biological and chemical agent threats, animal rights activists' vandalism and many bomb threats. In 2002, pipe bombs were found in 18 states including lowa and six people were injured in the bombings in lowa and Illinois. In 2005 and 2006, pipe bombs were used in attempted murder cases in two lowa cities. The lowa Department of Public Safety issued a 20091owa Uniform Crime Report showing 18 hate/bias crimes were reported statewide in 2009, with an average of 33 hate/bias crimes statewide from 2000-2009. According to the Southern Poverty Law Center, was one reported hate crime that occurred in Dubuque County in March of 2016. Probability of Future Occurrence While difficult to estimate, the probability for a terrorist event is "Unlikely" within the next 10 years in Dubuque County. Probabilitv Score: 1—Unlikely Dubuque County, lowa 3.193 Multi-jurisdictional Hazard Mitigation Plan 2018 Vulnerabilitv Overview A terrorism event could occur in either limited area of a jurisdiction or over the entire jurisdiction at once. This hazard has the ability to directly cause substantial structural losses and potentially loss of life. Maqnitude Score: 4�atastrophic Potential Losses to E�cisting Development Potential losses from Terrorism include all infrastructure, critical facilities, crops, humans and animals. The degree of impact would be directly related to the type of incident and the target. Potential losses could include cost of repair or replacement of damaged facilities, lost economic opportunities for businesses, loss of human life, injuries to persons, loss of food supplies, disruption of the food supply chain, and immediate damage to the surrounding environment. Secondary effects of infrastructure failure could include public safety hazards, spread of disease, increased morbidity and mortality among the local and distant populations, public panic and long-lasting damage to the environment. Terrorism events are rare occurrences and specific amounts of estimated losses for previous occurrences are not available due to the complexity and multiple variables associated with these types of hazards. In some instances, information about these events is secure and unavailable to the public in order to maintain national security and prevent future attacks. As discussed previously, it is difficult to quantify potential losses in terms of the jurisdictions most threatened by CBRNE (chemical, biological, radiological, nuclear, and high yield explosive) attack events due to the many variables and human element. Therefore, for the purposes of this plan, the loss estimates will take into account a hypothetical scenario. The attack scenario is staged at a Friday night high school football game. The hypothetical football stadium has approximately 500 persons in the stadium and concession areas on any home football game nights during the fall. Analysis of vulnerable populations is aided by a program developed by Johns Hopkins University in 2006 called Electronic Mass Casualty Assessment and Planning Scenarios (EMCAPS) http://vwvw.hopkins-cepar.orq/EMCAPS/EMCAPS.html which utilizes scenarios developed by the Department of Homeland Security. ""THE FOLLOWING HYPOTHETICAL SCENARIO IS FOR INSTRUCTIONAL AND ILLUSTRATIVE PURPOSES ONLY"" Chemical Attack— Toxic Gas— Chlorine Re/ease Scenario Overview: A bomb is attached to a truck trailer tanker carrying compressed chlorine and enters the high school football stadium parking lot. The entire contents of the tank escape to the atmosphere and the plume spreads to the stadium and the immediate surrounding parking lot area. This particular type of attack would cause harm to humans and could render portions of the stadium unusable for a short time period in order to allow for a costly clean-up. There might also be a fear by the public of long-term contamination of the stadium and the high school subsequent closing the high school. Dubuque County, lowa 3.194 Multi-jurisdictional Hazard Mitigation Plan 2018 Assumptions: (1) The population density is approximately 500 persons around the high school stadium (2) Chlorine is toxic and may damage eyes, skin and respiratory tract. (3) The rate of "worried well" is equal to 9 times the number of infected cases or the full exposed population, whichever is least. Table 3.63.

Potential losses with this type of scenario include both human and structural assets. Assumptions: (1) The population density in the parking lot during the beginning and ending of the game is high, at least 1 person /1 square feet. (2) The quantity of ANFO used is 500 Ibs. Table 3.64. Described Losses from an Improvised Explosive Device Attack - ANFO Total Dead 86 persons Total Traumatic Injuries 151 persons Total Urgent Care Injuries 745 persons Injuries not Requiring Hospitalization 279 persons Strudures and Other Physical Assets Vehicles— (Damages would certainly occur to vehicles and Replacement cost for approximately 350 vehicles @ depending on the proximity of other structures, damages $10,000 per vehicle inside the 200 ft. BATF described wnuld occur to the stadium complex itself. The exact Lethal Air Blast range = $ 3,500,000 amount of these damages is difficult to predict because Repair/repainting cost for approximately 70 vehicles @ of the large numbers of factors, including the type of $ 4,000 per vehicle inside the BATF described Falling structures nearby and the amount of insurance held by Debris Hazard = $280,000 vehicle owners.) Note: These are the numbers of persons that could be injured from an IED Attack if they are in the area. Dubuque County, lowa 3.195 Multi-jurisdictional Hazard Mitigation Plan 2018 Future Development As public events are held at various venues in the County, the potential may exist for these locations to become targets of attack. With human-caused hazards such as this that can have multiple variables involved, increases in development is not always a factor in determining risk, although the physical damages of the event may increase with the increased or newly developed areas. Climate Change lmpacts There are no known climate change impacts relevant to this hazard. Terrorism Hazard Summary by Jurisdiction The overall rating for any type of terrorism in the County is 2.65 "Moderate".

When the colder upper air sinks and warm moist air rises, storm clouds or 'thunderheads' develop, resulting in thunderstorms. This can occur singularly, in clusters or in lines. Severe thunderstorms most often occur in lowa in the spring and summer, during the afternoon and evenings, but can occur at any time. Other hazards associated with thunderstorms and lightning include: heavy rains causing flash flooding (discussed separately in Section 3.5.6) and tornadoes and windstorms (discussed further in Section 3.5.18). Liqhtninq All thunderstorms produce lightning, which often strikes outside of the area where it is raining and is known to fall more than 10 miles away from the rainfall area. Thunder is simply the sound that lightning makes. Lightning is a huge discharge of electricity. When lightning strikes, electricity shoots through the air and causes vibrations creating the sound of thunder. Nationwide, lightning kills 75 to 100 people each year. Lightning strikes can also start building fires, wildland fires, and damage electrical systems and equipment. Hail According to the National Oceanic and Atmospheric Administration (NOAA), hail is precipitation that is formed when updrafts in thunderstorms carry raindrops upward into extremely cold areas of the atmosphere causing them to freeze. The raindrops form into small frozen droplets and then continue to grow as they come into contact with super-cooled water which will freeze on contact with the frozen rain droplet. This frozen rain droplet can continue to grow and form hail. As long as the updraft forces can support or suspend the weight of the hailstone, hail can continue to grow. At the time when the updraft can no longer support the hailstone, it will fall down to the earth. For example, a Yd' diameter or pea sized hail requires updrafts of 24 mph, while a 2 '/d' diameter or baseball sized hail requires an updraft of 81 mph. The largest hailstone recorded in the United States was found in Vivian, South Dakota on July 23, 2010, measuring eight inches in diameter, almost the size of a soccer ball. Soccer-ball-sized hail is the exception, but even small pea sized hail can do damage. Hailstorms in lowa cause damage to property, crops, and the environment and kill and injure livestock. In the United States, hail causes more than $1 billion in damage to property and crops each year. Much of the damage inflicted by hail is to crops. Even relatively small hail can shred plants to ribbons in a matter of minutes. Vehicles, roofs of buildings and homes and landscaping Dubuque County, lowa 3.197 Multi-jurisdictional Hazard Mitigation Plan 2018 are the other things most commonly damaged by hail. Hail has been known to cause injury to humans, occasionally, these injuries can be fatal. Table 3.65 below describes typical damage impacts of the various sizes of hail. Table 3.65.

Warninq Time Score: 2-12-24 hours Duration Score: 2—Less than 1 day Geographic Location/6ctent Thunderstorms and the associated hail and lightning impact the entire County with relatively similar frequency. Although, these events occur similarly throughout the planning area, they are more frequently reported in more urbanized areas. In addition, damages are more likely to occur in more densely developed urban areas as well as to cropland. Figure 3.61 displays the average number of days with thunder experienced throughout different areas of the county each year, showing the County experiences between 40.5 to 50.4 days with thunder per year.

The data is kept on lowa Environmental Mesonet, lowa State University Department of Agronomy website, Dubuque County, lowa 3200 Multi-jurisdictional Hazard Mitigation Plan 2018 (http://mesonet.aqron.iastate.edu/vtec/search.php). During the 31-year period from 1986 to 2016, there were 92 severe thunderstorm watches and 247 warnings. This calculates to an annual average of 3.1 watches and 8.2 warnings. Although NCDC provides estimates of crop losses, crop insurance payment statistics are considered a more accurate resource for this data. According to the USDA Risk Management Agency, insured crop losses in Dubuque County as a result of hail from 2007 to 2016 totaled $323,986 (see Table 3.68) and $545,573 from windstorms. There was no crop damage reported from lightning. Table 3.68.

Since lightning accompanies thunderstorms, it can be assumed that lightning occurs more often than damages are reported. These rates of occurrence are expected to continue in the future. Based on NCDC data, there have been 14 damaging hail events, 2 damaging lightning events and 66 damaging thunderstorm wind events. This translates to a combined annual average of 3.4 damaging events per year respectively. Based on this history, damaging hail and thunderstorm wind occur in the planning area multiple times each year making the probability for damaging events "Highly Likely" in any given year. Probabilitv Score: 4—Highly Likely Vulnerabilitv Overview In general, assets in the County are vulnerable to thunderstorms, winds, lightning and hail including people, crops, vehicles, and built structures. According to the 2013 lowa Hazard Mitigation Plan, of the 8 hazards for which data was available to estimate annualized losses, thunderstorm with lightning and hail ranked 4'h with $30 million in annualized losses based on data spanning a 17-year period. Although this hazard results in high annual losses, generally private property insurance and crop insurance cover the majority of losses. Considering insurance coverage as a recovery capability and therefore mitigation of devastating impacts to the economy, the overall impact on jurisdictions is reduced; therefore, this hazard's magnitude score to the planning area is "limited". Dubuque County, lowa 3201 Multi-jurisdictional Hazard Mitigation Plan 2018 Maqnitude Score: 2—Limited Potential Losses to E�cisting Development Most lightning damages occur to electronic equipment located inside buildings. But structural damage can also occur when a lightning strike causes a building fire. In addition, lightning strikes can cause damages to crops if fields light on fire. Communications equipment and warning transmitters and receivers can also be knocked out by lightning strikes. There have not been any fatalities in Dubuque County from lightning strikes. Thunderstorm winds and hail can cause damage to property, vehicles, trees, and crops. Propertv and Crop Losses Table 3.69 provides the estimated annualized property damages resulting from Thunderstorms, including lightning, hail and wind. This annualized damage has been compared to the total building exposure for Dubuque County and the level of damage is minimal compared to the value of building exposure. Table 3.69.

To minimize vulnerability, protective measures could be implemented such as wind-resistant construction, lightning rods, surge protection and use of materials less prone to hail/wind damage. Climate Change lmpacts According to the 2010 Climate Change lmpacts on lowa report, growing evidence points to stronger summer storm systems in the Midwest. Studies have not been done to conclusively say that severe storms, including hail, lightning and strong winds, are increasing. However, with summer temperatures becoming warmer and humidity levels increasing, an increase in the likelihood of these hazards is plausible. Thunderstorm, Lightning and Hail Hazard Summary by Jurisdiction The following hazard summary table shows that this hazard does not vary significantly by jurisdiction.

Tornado: The NWS defines a tornado as "a violently rotating column of air extending from a thunderstorm to the ground." It is usually spawned by a thunderstorm and produced when cool air overrides a layer of warm air, forcing the warm air to rise rapidly. Often, vortices remain suspended in the atmosphere as funnel clouds. When the lower tip of a vortex touches the ground, it becomes a tornado and a force of destruction. Tornadoes are the most violent of all atmospheric storms and are capable of tremendous destruction. Wind speeds can exceed 250 miles per hour, and damage paths can be more than one mile wide and 50 miles long. Tornadoes have been known to lift and move objects weighing more than 300 tons a distance of 30 feet, toss homes more than 300 feet from their foundations, and siphon millions of tons of water from water bodies. Tornadoes also generate a tremendous amount of flying debris or "missiles," which often become airborne shrapnel that causes additional damage. If wind speeds are high enough, missiles can be thrown at a building with enough force to penetrate windows, roofs and walls. However, the less spectacular damage is much more common. Windstorm: Windstorms for purposes of this plan refer to other non-tornadic damaging winds of thunderstorms including downbursts, microbursts and straight-line winds. Downbursts are localized currents of air blasting down from a thunderstorm, which induce an outward burst of damaging wind on or near the ground. Microbursts are minimized downbursts covering an area of less than 2.5 miles across. They include a strong wind shear (a rapid change in the direction of wind over a short distance) near the surface. Microbursts may or may not include precipitation and can produce winds at speeds of more than 150 miles per hour. Straight-line winds are generally any thunderstorm wind that is not associated with rotation. It is these winds, which can exceed 100 mph, which represent the most common type of severe weather and are responsible for most wind damage related to thunderstorms. Since thunderstorms do not have narrow tracks like tornadoes, the associated wind damage can be extensive and affect entire (and multiple) counties. Objects like trees, barns, outbuildings, high-profile vehicles, and power lines/poles can be toppled or destroyed, and roofs, windows, and homes can be damaged as wind speeds increase. Strong winds can occur year-round in lowa. These winds typically develop with strong pressure gradients and gusty frontal passages. The closer and stronger two systems are, (one high pressure, one low pressure) the stronger the pressure gradient, and therefore, the stronger the winds are. Objects such as trees, barns, outbuildings, high-profile vehicles and power line/poles Dubuque County, lowa 3204 Multi-jurisdictional Hazard Mitigation Plan 2018 can be toppled or destroyed, and roofs, windows and homes can be damaged as wind speeds increase. Downbursts can be particularly dangerous to aviation. The NWS can issue High Wind Watch, High Wind Warning, and Wind Advisory to the public. The following are the definitions of these issuances: • High Wind Watch—This is issued when there is the potential of high wind speeds developing that may pose a hazard or is are life-threatening. • High Wind Warning—The 1-minute surface winds of 35 knots (40 mph) or greater lasting for one hour or longer, or winds gusting to 50 knots (58 mph) or greater, regardless of duration, that are either expected or observed over land. • High Wind Advisory—This is issued when high wind speeds may pose a hazard. Sustained winds 25 to 39 mph and/or gusts to 57 mph.

Only one F5 rated tornado has occurred in lowa during this timeframe (Parkersburg in 2008). Since 1980, there have been on average 47 tornadoes per year in lowa. Most tornadoes occurred in May and June but can occur during any month. Also, mid-afternoon until around sunset is the peak time of day for tornado activity. There have been 763 injuries and 26 deaths attributable to tornadoes (source: National Weather Service, lowa Tornado Climatology Report 1980-2011). Tornadoes can occur in the entire planning area.

Tornado watches can be delivered to those in the path of these storms several hours in advance. Lead time for actual tornado warnings is about 30 minutes. Tornadoes have been known to change paths very rapidly, thus limiting the time in which to take shelter. Tornadoes may not be visible on the ground if they occur after sundown or due to blowing dust or driving rain and hail.

Windstorms Previous Occurrences According to the NCDC database, there were 11 high wind events in Dubuque County from 1993 to 2016. During this time period, there were 1 injury and no deaths. There was an estimated $120,000 in property damages. Recorded wind gusts ranged from a high of 55 knots to a low of 35 knots. Table 3.74 provides a summary of the wind speeds reported for the wind events. Dubuque County, lowa 3210 Multi-jurisdictional Hazard Mitigation Plan 2018 Table 3.74.

Therefore, it is a high probability that some portion of Dubuque County will experience tornado activity in any given year. According to NCDC, there were 11 separate high wind events from 1993 to 2016 (24-year period) in Dubuque County. Based on this data there is a 46 percent annual probability of high wind events in any given year. Therefore, the probability rating is "Highly Likely". Probabilitv Score: 4—Highly Likely Figure 3.66 below shows the probability of a windstorm event (65 knots or greater) in the U.S. The Dubuque County planning area is colored lime and dark green, showing that 65+ knot winds are probable to occur 1.00 to 1.50 times a year.

Those most at risk from tornadoes include people living in mobile homes, campgrounds, and other dwellings without secure foundations or basements. People in automobiles are also very vulnerable to twisters. Table 3.75 provides the number of mobile homes in each jurisdiction in Dubuque County according to the U.S. Census Bureau's 2015 American Community Survey Table 3.75.

People who may not understand watches and warnings due to language barriers are also at risk. According to the 2013 lowa Hazard Mitigation Plan, of the 8 hazards for which data was available to estimate annualized losses, tornadoes ranked 3''with $36 million in annualized losses based on data spanning a 63-year period. Due to the potential for damaging tornadoes in the planning area, the magnitude was determined to be a 4, catastrophic. Maqnitude Score: 4—Catastrophic Potential Losses to E�cisting Development In Dubuque County, the NCDC estimate for past property damages resulting from tornadoes from 1950— 2016 (67 years) was $28,931,200. This translates to an annualized loss of over $431,800. For windstorms, NCDC loss estimates were $120,000 from 1993 to 2016 (24 years). This translates to an annualized loss of nearly $5,000. Loss of Use Overhead power lines and infrastructure are also vulnerable to damages from windstorms. Potential losses would include cost of repair or replacement of damaged facilities, and lost economic opportunities for businesses. Public safety hazards include risk of electrocution from downed power lines. Specific amounts of estimated losses are not available due to the complexity and multiple variables associated with this hazard. Refer to the electric power loss of use estimates provided in 0 in the Winter Storm hazard section. Crop Losses Crop insurance payments for wind damage are discussed in Section 3.5.17, Thunderstorms with Lightning and Hail. Future Development Public buildings such as schools, government offices, as well as other buildings with a high occupancy and mobile home parks should consider inclusion of a tornado saferoom to shelter occupants in the event of a tornado. Windstorm is primarily a public safety and economic concern, and the planning area is located in a region with very high frequency of occurrence. Windstorm can cause damage to structures Dubuque County, lowa 3214 Multi-jurisdictional Hazard Mitigation Plan 2018 and power lines which in turn create hazardous conditions for people. Debris flying from high wind events can shatter windows in structures and vehicles and can harm people that are not adequately sheltered. Although windstorms occur frequently in the planning area and damages to property occur, much of the damage is generally covered by private insurance. This results in less impact to individuals and the community since recovery is facilitated by insurance. Climate Change lmpacts According to the 2010 Climate Change lmpacts on lowa report, growing evidence points to stronger summer storm systems in the Midwest. Studies have not been done to conclusively say that severe storms, including tornadoes, are increasing. However, with summer temperatures becoming warmer and humidity levels increasing, an increase in the likelihood of tornadic activity is plausible. Tornado/Windstorm Hazard Summary by Jurisdiction The magnitude was rated as a level 4 for all the participating jurisdictions, as they are all vulnerable to tornado and windstorm damage. The factors of probability, warning time, and duration are also equal across the planning area. This hazard does not substantially vary by jurisdiction.

There is no rail transportation in Dubuque County. The transportation incidents can involve any mode of transportation that directly threatens life and which results in property damage and/or death(s)/injury(s) and/or adversely impact a community's capabilities to provide emergency services. Incidents involving buses and other high occupancy vehicles could trigger a response that exceeds the normal day-to-day capabilities of response agencies. An air transportation incident may involve a military, commercial or private aircraft. Air transportation is playing a more prominent role in transportation as a whole. Airplanes and helicopters are used to transport passengers for business and recreation as well as thousands of tons of cargo. A variety of circumstances can result in an air transportation incident; mechanical failure, pilot error, enemy attack, terrorism, weather conditions and on-board fire can all lead to an air transportation incident. Highway transportation incidents are very complex. Contributing factors can include a roadway's design and/or pavement conditions (e.g. rain, snow and ice), a vehicle's mechanical condition (e.g. tires, brakes, lights), a driver's behavior (e.g. speeding, inattentiveness and seat belt usage), the driver's condition (e.g. alcohol use, age-related conditions, physical impairment) and driver inattention by using a wireless device. In fact, the driver's behavior and condition factors are the primary cause in an estimated 67 percent of highway crashes and a contributing factor in an estimated 95 percent of all crashes.

Dubuque County, lowa 3218 Multi-jurisdictional Hazard Mitigation Plan 2018 The Dubuque Regional airport, constructed in 1948, is owned by the City of Dubuque and is located six miles south of Dubuque. Regional access to the airport is from U.S. Highway 61. An airport commission was established by the city to manage the airport. The FAA recognizes the airport as playing a role in the national airport system and includes the airport in the National Plan of Integrated Airport Systems (NPIAS) as a non-hub primary commercial service airport. (A non-hub airport is one that enplanes more than 10,000, but less than 0.05 percent of the total U.S. passengers.) The lowa Aviation System Plan identifies the Dubuque Regional Airport as a Commercial Service airport. Commercial Service airports support scheduled airline service and have the infrastructure and services available to support a full range of general aviation activity.

The combination of cars and trucks, farm equipment, wildlife, unpredictable weather conditions, potential mechanical problems and human error always leaves the potential for a transportation accident. Based on the available information, the probability of air transportation or highway incident that directly threatens life and which results in property damage and/or death(s)/injury(s) and/or adversely impact a community's capabilities to provide emergency services is "Highly Likely" with greater than 33 percent likelihood to occur in any given year. Probabilitv Score: 4—Highly Likely Vulnerabilitv Overview Transportation incidents can almost always be expected to occur in specific areas, on or near airports, roadways or other transportation infrastructure. The exception is air transportation incidents, which can occur anywhere. However, it is difficult to predict the magnitude of any specific event because these types of events are accidental and the circumstances surrounding these events will impact the extent of damage or injuries that occur. The number of urban and rural highway/roadway transportation accidents from 2007 to 2016 was a total of 19,313 crashes during this 10-year time period (average nearly 2,000 per year). Fifty-eight (58) fatalities occurred during this time period (averaging nearly six per year). Transportation incident has resulted in the most deaths historically in the county compared to other hazards. Due to the potential for fatalities to occur, this hazard received a magnitude rating of "Catastrophic". Maqnitude Score: 4�atastrophic Dubuque County, lowa 3221 Multi-jurisdictional Hazard Mitigation Plan 2018 Potential Losses to E�cisting Development The U.S. Department of Transportation Federal Highway Administration issued a technical advisory in 1994 providing suggested estimates of the cost of traffic crashes to be used for planning purposes. These figures were converted from 1994 dollars to 2016 dollars using an annual inflation rate of 2.85 percent. The costs are listed below in Table 3.79. Table 3.79.

Adjusted to 2014 dollars and lowa Department of Transportation's Offce of Traffc and Safety,http://www.iowadot.qov/creshanalvsis/index.htm? Based on the 10 years of data, the annual average cost of transportation accidents in Dubuque County is $57,899,949. Estimated losses as a result of rail and air transportation are not available for this analysis. Future Development Current population trends indicate an increase in population in Dubuque County. If the volume of traffic on the county roads, highways and interstates increases with population increase, the number of traffic accidents will likely also increase. Climate Change lmpact If projections regarding milder winters come to fruition, climate change impacts may reduce the number of transportation incidents associated with some severe weather. However, if ice occurs, rather than snow, this could result in higher incidents of weather-related accidents.

This section presents the mitigation strategy updated by the Hazard Mitigation Planning Committee (HMPC) based on the updated risk assessment. The mitigation strategy was developed through a collaborative group process and consists of updated general goal statements to guide the jurisdictions in efforts to lessen disaster impacts as well as specific mitigation actions that can be put in place to directly reduce vulnerability to hazards and losses. The following definitions are based upon those found in the March 2013 Local Mitigation Planning Handbook: • Goals are general guidelines that explain what the community wants to achieve with the plan. They are usually broad policy-type statements that are long-term, and they represent visions for reducing or avoiding losses from the identified hazards. • Mitigation Actions are specific actions that help achieve goals. 4.1 Goals 44 CFR Requirement§201.6(c)(3)(i): [The hazard mitigation strategy shall include a] description of mitigation goals to reduce or avoid long-term vulnerabilities to the identified hazards. This planning effort is an update to an existing hazard mitigation plan. Therefore, the goals from the 2013 Dubuque County Hazard Mitigation Plan were reviewed to determine if they are still valid. The HMPC participated in a facilitated discussion during their second meeting to review and update the plan goals. To ensure that the goals are comprehensive and support State goals, the 2013 State Hazard Mitigation Plan goals were reviewed as well. The HMPC also reviewed common categories of mitigation goals from other plans. The revised goals for this plan update are provided below: • Goal 1: Increase capabilities within Dubuque County entities to mitigate the effects of hazards by enhancing existing or designing and adopting new policies that will reduce damaging effects of hazards. Dubuque County,lowa 4.1 Multi-jurisdictional Hazard Mitigation Plan 2018 • Goal 2: Protect the most vulnerable populations, buildings and critical facilities within Dubuque County through the implementation of cost effective and technically feasible mitigation projects. • Goal 3: Improve the level of responder, government, business and citizen awareness and preparedness for disasters. • Goal 4: Develop programs to assure that response agencies, governments, educational institutions and local businesses are able to operate during times of disaster. 4.2 Identification and Analysis of Mitigation Actions 44 CFR Requirement§201.6(c)(3)(ii): The mitigation strategy shall include a section that identifies and analyzes a comprehensive range of specific mitigation actions and projects being considered to reduce the effects of each hazard, with particular emphasis on new and existing buildings and infrastructure. During the second meeting of the HMPC, sample results of the risk assessment update were provided to the HMPC members. Additionally, the full draft of the Risk Assessment Chapter was provided for review by the HMPC members and to lay the framework for the impacts to be addressed by the updated mitigation strategy. Also at meeting #2, each jurisdiction was provided with a handout listing the actions they included in the previous hazard mitigation plan. The mitigation strategy of the previous plan consisted of 569 individual jurisdictional actions. Jurisdictional representatives were instructed to work with others in their jurisdiction to update the status of each of the previous actions. The status updates were provided between meeting #2 and meeting #3. OF the 569 previous actions, 45 have been completed, 285 are continuing, and 239 were deleted. The list of the completed and deleted actions is provided in Appendix C with comments providing additional details, as available. For a comprehensive range of mitigation actions to consider, the jurisdictions were provided relevant information and sources to be used in development of new mitigation actions including: • Plan Goals • Previous Actions from 2013 Plan • Key Issues from Risk Assessment • FEMA's Mitigation Ideas booklet • State Priorities for Hazard Mitigation Assistance Grants • Public Opinion from Surveys To facilitate discussion and ideas on new actions that jurisdictions may want to submit to the plan update, the planning committee reviewed the plan goals that were updated at meeting #2. Key issues/problem statements for the hazards in the risk assessment were discussed as well as the actions from the 2013 plan that were identified relative to each hazard. The discussion was geared toward identifying any gaps that may exist between the problems identified and actions already developed to address the problems. To provide consideration of a comprehensive range of alternatives, FEMA's Mitigation Ideas Booklet was also reviewed for additional ideas/alternatives for new actions. After the committee meeting, jurisdictions reviewed the materials to determine final mitigation actions to submit to the plan update. Dubuque County,lowa 4.2 Multi-jurisdictional Hazard Mitigation Plan 2018 The jurisdictions were encouraged to be comprehensive and include all appropriate actions to work toward becoming more disaster resistant. They were encouraged to maintain a realistic approach and were reminded that the hazard mitigation plan is a "living documenY'. As capabilities, vulnerabilities, or the nature of hazards that threaten each jurisdiction change, the mitigation actions can and should be updated to reflect those changes, including addition or deletion of actions, as appropriate. As part of the meeting discussion, jurisdictions were instructed to consider the potential cost of each project in relation to the anticipated future cost savings. This type of discussion allowed the committee as a whole to understand the broad priorities and enable discussion of the types of projects most beneficial to all jurisdictions within Dubuque County. 4.3 Implementation of Mitigation Actions 44 CFR Requirement§201.6(c)(3)(ii): The mitigation strategy shall include an action strategy describing how the actions identified in paragraph (c)(2)(ii)will be prioritized, implemented, and administered bythe local jurisdiction. Prioritization shall include a special emphasis on the extent to which benefits are maximized according to a cost benefits review of the proposed projects and their associated costs. Jurisdictional representatives worked with others in their community to finalize the actions to be submitted to the updated mitigation strategy. Throughout the discussion of the types of projects that the committee would include in the mitigation plan, emphasis was placed on the importance of a benefit-cost analysis in determining project priority. The Disaster Mitigation Act regulations state that benefit-cost review is the primary method by which mitigation projects should be prioritized. Recognizing the federal regulatory requirement to prioritize by benefit- cost, and the need for any publicly funded project to be cost-effective, the HMPC decided to pursue implementation according to when and where damage occurs, available funding, political will, jurisdictional priority, and priorities identified in the lowa State Hazard Mitigation Plan. Due to many variables that must be examined during project development, the benefit/cost review at the planning stage, primarily consisted of a qualitative analysis. For each action, the jurisdictions included a narrative describing the types of benefits that could be realized with implementation of the action. Where possible, the cost was estimated as closely as possible with further refinement to occur as project development occurs. Cost-effectiveness will be considered in additional detail if/when seeking FEMA Hazard Mitigation Assistance grant funding or other grant funding for eligible projects identified in this plan. At that time, additional information will be researched to provide for a quantitative benefit-cost analysis. To provide a mechanism for jurisdictions to prioritize actions, a modified STAPLEE worksheet was completed by the jurisdictions for each new and continued action submitted for the updated mitigation strategy. The modified STAPLEE worksheet includes elements to consider protection of life and reduction of damages. Although the STAPLEE method was a component of the prioritization method utilized for the 2013 plan, there were other scoring elements included. For the plan update, the modified STAPLEE worksheet was chosen to re-evaluate all continuing and new actions as this was deemed a more simplified approach and avoided some redundancies and double-counting of benefits that could occur with the previous method. Dubuque County,lowa 4.3 Multi-jurisdictional Hazard Mitigation Plan 2018 The STAPLEE prioritization method in general is a tool used to assess the costs and benefits, and overall feasibility of mitigation actions. STAPLEE stands for the following: • Social: Will the action be acceptable to the community? Could it have an unfair effect on a particular segment of the population? • Technical: Is the action technically feasible?Are there secondary impacts? Does it offer a long-term solution? • Administrative: Are there adequate staffing, funding, and maintenance capabilities to implement the project? • Political: Will there be adequate political and public support for the project? • Legal: Does your jurisdiction have the legal authority to implement the action? • Economic: Is the action cost-beneficial? Is there funding available?Will the action contribute to the local economy? • Environmental: Will there be negative environmental consequences from the action? Does it comply with environmental regulations? Is it consistent with community environmental goals? Additional questions were added to the modified STAPLEE worksheet to include elements to consider protection of historic properties and time to implement as well as elements to consider mitigation effectiveness related to protection of life and reduction of damages. Figure 4.1 is a sample of the the Action Plan worksheet. The Prioritization Sectionis at the bottom of the worksheet. There is a total possible prioritization score of 19. Those actions that scored 13 or Higher were given a priority rating of"High". Those actions that scored 7-12 were given a priority rating of"Medium". And those actions that scored less than 7 were given a rating of"LovJ'. Dubuque County,lowa 4.4 Multi-jurisdictional Hazard Mitigation Plan 2018 Figure0.1.

The Action ID for each action has been carried over from the 2013 plan for continuing actions. As a result of completed and deleted actions, the Action ID does not follow a sequential order. New actions were assigned the next sequential Action ID for each jurisdiction. Following the action summary table, additional details are provided for each continuing and new action in Table 4.2.

The chapter also discusses incorporating the plan into existing planning mechanisms and how to address continued public involvement. 5.1 Monitoring, Evaluating, and Updating the Plan 44 CFR Requirement 201.6(c)(4): The plan maintenance process shall include a section describing the method and schedule of monitoring, evaluating, and updating the mitigation plan within a five-year cycle. 5.1.1 Hazard Mitigation Planning Committee (HMPC) With adoption of this plan, the HMPC will be tasked with plan monitoring, evaluation and maintenance. The participating jurisdictions and agencies, led by the Dubuque County Emergency Management Coordinator, agree to: • Meet annually to review the Hazard Mitigation Plan; • Act as a forum for hazard mitigation issues; • Disseminate hazard mitigation ideas and activities to all participants; • Pursue the implementation of high priority, low- or no-cost recommended actions; • Maintain vigilant monitoring of multi-objective, cost-share, and other funding opportunities to help the community implement the plan's recommended actions for which no current funding exists; • Monitor and assist in implementation and update of this plan; • Keep the concept of mitigation in the forefront of community decision making by identifying plan recommendations when other community goals, plans, and activities overlap, influence, or directly affect increased community vulnerability to disasters; • Report on plan progress and recommended changes to the Dubuque County Board of Supervisors and governing bodies of participating jurisdictions; and • Inform and solicit input from the public. Dubuque County,lowa 5.1 Multi-jurisdictional Hazard Mitigation Plan 2018 The HMPC is an advisory body and can only make recommendations to county, city, town, or district elected officials. Its primary duty is to see the plan successfully carried out and to report to the community governing boards and the public on the status of plan implementation and mitigation opportunities. Other duties include reviewing and promoting mitigation proposals, hearing stakeholder concerns about hazard mitigation, passing concerns on to appropriate entities, and posting relevant information in areas accessible to the public. 5.1.2 Plan Maintenance Schedule The HMPC agrees to meet annually to monitor progress, discuss recent hazard events, changes in development that impact vulnerability, and update the mitigation strategy. The Dubuque County Emergency Management Coordinator will be responsible for initiating the plan reviews which will be integrated into the regularly scheduled Emergency Management Commission meetings. In coordination with the other participating jurisdictions, a five-year written update of the plan will be submitted to the lowa Homeland Security and Emergency Management Department and FEMA Region VII per Requirement §201.6(c)(4)(i) of the Disaster Mitigation Act of 2000, unless disaster or other circumstances (e.g., changing regulations) require a change to this schedule. 5.1 .3 Plan Maintenance Process Evaluation of progress can be achieved by monitoring changes in vulnerabilities identified in the plan. Changes in vulnerability can be identified by noting: • Decreased vulnerability as a result of implementing recommended actions, • Increased vulnerability as a result of failed or ineffective mitigation actions, and/or • Increased vulnerability as a result of new development (and/or annexation). The annual reviews and updates to this plan will: • Consider changes in vulnerability due to action implementation, • Document success stories where mitigation efforts have proven effective, • Document areas where mitigation actions were not effective, • Document any new hazards that may arise or were previously overlooked, • Incorporate new data or studies on hazards and risks, • Incorporate new capabilities or changes in capabilities, • Incorporate growth and development-related changes to inventories, and • Incorporate new action recommendations or changes in action prioritization. In order to best evaluate the mitigation strategy during plan review and update, the participating jurisdictions will follow the following process: • A representative from the responsible office identified in each mitigation action will be responsible for tracking and reporting the action status on an annual basis to the jurisdictional HMPC member and providing input on any completion details or whether the action still meets the defined objectives and is likely to be successful in reducing vulnerabilities. Dubuque County, lowa 52 Multi-jurisdictional Hazard Mitigation Plan 2018 • If the action does not meet identified objectives, the jurisdictional HMPC member will determine what additional measures may be implemented, and an assigned individual will be responsible for defining action scope, implementing the action, monitoring success of the action, and making any required modifications to the plan. • As part of the annual review process, the Dubuque County Emergency Management Coordinator will provide the updated Mitigation Strategy with current status of each mitigation action to the County Board of Supervisors and County Department Heads as well as all Mayors, City Clerks, and School District Superintendents requesting that the mitigation strategy be incorporated, where appropriate in other planning mechanisms. Changes will be made to the plan to accommodate for actions that have failed or are not considered feasible after a review of their consistency with established criteria, time frame, community priorities, and/or funding resources. Actions that were not ranked high but were identified as potential mitigation activities will be reviewed as well during the monitoring and update of this plan to determine feasibility of future implementation. Updating of the plan will be by written changes and submissions, as the Dubuque County HMPC deems appropriate and necessary, and as approved by the Dubuque County Board of Supervisors and the governing boards of the other participating jurisdictions. 5.2 Incorporation into Existing Planning Mechanisms 44 CFR Requirement §201.6(c)(4)(ii): [The plan shall include a] process by which local governments incorporate the requirements of the mitigation plan into other planning mechanisms such as comprehensive or capital improvement plans, when appropriate. Many of the small jurisdictions in Dubuque County do not have standing formal planning mechanisms such as a Comprehensive Plan or Capital Improvements Plan through which formal integration of mitigation actions can be documented. As a result activities that occur in these small communities are developed through, annual budget planning, regular City Council Meetings and other community forums rather than a formal planning process. Planning mechanisms in the participating jurisdictions include: • Comprehensive Plans�ities of Asbury, Bernard, Dyersville, Epworth, Farley, Rickardsville, Zwingle • Various ordinances of participating jurisdictions, including floodplain management ordinances in NFIP-participating communities; • Dubuque County Emergency Operations Plan; • Capital Improvement Plans—Cities of Bernard, Dyersville, Farley, Zwingle, as well as xxx and public school districts For a detailed summary of planning mechanisms and other mitigation-related capabilities, see Table 2.8 in Chapter 2 Dubuque County, lowa 5.3 Multi-jurisdictional Hazard Mitigation Plan 2018 lncorporation of Previous Hazard Mitigation Plan into E�cisting Planning Mechanisms Instances of incorporation of the plan into previous planning mechanisms varied across jurisdictions. A review of the completed actions and other identified and/or completed mitigation initiatives demonstrates that mitigation has been accomplished through existing planning mechanisms. lncorporation of Updated Hazard Mitigation Plan into existing Planning Mechanisms Going Forward Where possible, plan participants will use existing plans and/or programs to implement hazard mitigation actions. After the annual review of the Hazard Mitigation Plan, the Dubuque County Emergency Management Coordinator will provide the updated Mitigation Strategy with current status of each mitigation action to the County Commission and County Department Heads as well as all Mayors, City Clerks, and School District Superintendents requesting that the mitigation strategy be incorporated, where appropriate in other planning mechanisms. Jursidction-specific implementations may include: 1. Incorporation into annual emergency management training, planning, and purchasing plans 2. Coordination of mitigation strategy with County's Emergency Management Grant Fund, as well as seeking additional funding opportunities 3. Integration of risk assessment into future updates of the Comprehensive Emergency Operations Plan 4. Integration of mitigation strategy into county and community comprehensive plans 5. Integration of mitigation strategy into county and community capital improvement plans 6. Integration of mitigation strategy into annual budget planning processes 5.3 Continued Public Involvement 44 CFR Requirement §201.6(c)(4)(iii): [The plan maintenance process shall include a] discussion on how the community will continue public participation in the plan maintenance process. The update process provides an opportunity to publicize success stories from the plan's implementation and seek additional public comment. The public will be involved in the plan maintenance process by publication of a Press Release after each annual review indicating the committee has met with a summary of mitigation action status updates and highlights of specific completed mitigation actions, as applicable. When the HMPC reconvenes for the update, it will coordinate with all stakeholders participating in the planning process, including those who joined the HMPC after the initial effort, to update and revise the plan. Public notice will be posted through available website postings and social media outlets.
