Disaster Mitigation Plan change D~ ~~~ MEMOR.ANDUM February 25, 2004 TO: The Honorable Mayor and City Council Members FROM: Michael C. Van Milligen, City Manager SUBJECT: City of Dubuque Pre Disaster Mitigation Plan On January 5, 2004 the City Council approved the revised Pre Disaster Mitigation Plan (POMP) prepared by East Central Intergovernmental Agency (ECIA) for the City of Dubuque. This plan was reviewed by the State of Iowa Homeland Security and Emergency Management Division and was returned to ECIA with recommended changes. A review of these changes by ECIA and City staff indicates that they are minor and do not change the intent or purpose of any sections of our plan. Emergency Management CoordinatotTom Berger recommends approval of the amended City of Dubuque Pre Disaster Mitigation Plan. I concur with the recommendation and respectfully request Mayor and City Council approval. (liJj ~ AiL Michael C. Van Milligen -- MCVM/jh Attachment cc: Barry Lindahl, Corporation Counsel Cindy Steinhauser, Assistant City Manager Thomas I. Berger, Emergency Management Coordinator Date: February 24th, 2004 To: Michael C. Van Milligen , City Manager From: Thomas 1. Berger, EMA Coordinator Subject: City of Dubuque Pre Disaster Mitigation Plan On January 5, 2004 the City Council approved the revised Pre Disaster Mitigation Plan (pDMP) prepared by East Central Intergovernmental Agency (ECIA) for the City of Dubuque. This is an expansion of an existing plan that was previously prepared by ECIA and the City of Dubuque in 2001. The PDMP is a requirement for local governments to have in place prior to request federal funds (such as FEMA) for local disasters. As part of this process, ECIA has submitted our plan to the State of Iowa Homeland Security and Emergency Management Division and/or the Federal Emergency Management Agency for review and comment. This plan was reviewed by the State of Iowa Homeland Security and Emergency Management Division and was returned to ECIA with recommended changes. A review of these changes by ECIA and city staff indicates that they are minor and do not change the intent or purpose of any sections of our plan. The changes are mainly justification of the information we already provided to ECIA and they present the information in a different manner than we originally submitted. ECIA has amended our plan to include the new language and information to have our plan adhere to the federal requirements. After reviewing the proposed amendments to the plan, I feel that we should allow the minor changes presented in the document as the changes do not change the intent or purpose of any sections of our plan. Thank you for your consideration on this plan. Pre-Disaster Mitigation Plán Planning Process The City of Dubuque has developed a local hazard mitigation plan in compliance with the Pre- Disaster Mitigation (pDM) planning requirements of the Disaster Mitigation Act of 2000 (DMA2000). A planning team consisting of members of the City Council, representatives fTom City Engineering, City Planning, Police Department, Fire Department, Public Works, Ambulance, Emergency Management Services, Public Relations, and the regional Council of Governments. (See Appendix A for a list ofteam members.) The planning process began with a review of the existing City of Dubuque Hazard Mitigation Plan of 2002. (In order to avoid confusion of these two documents, this document will be referred to as the PDM Plan.) The team met bi-weekly to further refine the document and provide greater detaii in terms of historic data, vulnerability, risks and goals. Meeting notices and agendas were posted in advance of the meetings at City Hall. The public was encouraged to attend the meetings and/or offer input via City Hall. Planning meetings and workshops were held on June 11, 2003, June 20, 2003 and December 23, 2003 for public input and comment during the drafting stages of the plan and a public hearing was held on January 5, 2004 for public input prior to approval and adoption of the plan. All meetings of the PDM Committee are subject to and abide by the requirements of the Iowa Open Meetings laws. (See Appendix R for Iowa Open Meetings law.) The City of Dubuque will place on their local cable access channel and post at City Hall notices that copies of the City's Pre-Disaster Mitigation Plan are available to the general public. The City will review the PDM Plan after its formal adoption and post all non-classified portions of the Plan on the City Website. IdentifYing Hazards The City of Dubuque is located on the Mississippi River, where the eastern border of Iowa meets with Wisconsin and illinois. It has a population of 57,538 and serves a region of 250,000 people. The City is the hub of several highways; four-lane US Highway 20 runs east- west, four-lane US Highway 61 runs northeast and south, US Highway 52 runs north-south generally following the Mississippi River and US Highway 151 exits Dubuque to southwest and northeast. The Midwestem part of the United States routinely experiences many snowfalls every winter along with spring flooding in the many rivers in this region as a result of spring snowmelt and occasional flash floods due to a combination of the somewhat regular thunderstorms and heavy rainfalls and the impervious clay soil found in this area. In addition tornadoes occur commonly throughout the Midwest in spring and early summer, although they have been known to occur at anytime of the year. Dubuque Pre-Disaster Mitigation Plan The Planning team identified several hazards that are addressed iIrthis PDM Plan. The hazards were identified through the review of the previous Hazard Mitigation Plan, research of historic data fTom area newspapers, FIRM maps and additional GIS maps developed through the regional council of governments and valuation information fTom the County Assessor's office. This information was again used along with a vulnerability assessment was used to determine those hazards that present the greatest risk to the City. The following Table identifies the hazards that were identified as having a potential risk to the City. TABLE 1 - Identified Hazards Hazard How Identified Why Identified Floods .

Profiling of Identified Hazards Floods The City of Dubuque borders the Mississippi River on its east City limits. The Catfish Creek; South, Middle and North Forks flow through the City and join at various locations emptying into the Mississippi River. The Little Maquoketa River drains easterly across Dubuque County north of the City limits; however has resulted in flooding within the City in past years. The National Oceanic and Atmospheric Administration (NOAA) increased its recordation of flood information in 1993. The recorded information now includes more specific weather data and reported flood damages. Recorded flood events in Dubuque County and across the state indicate several patterns of behavior. (See Appendix B for NOAA recorded data. Note: The NOAA data is reported on a countywide basis with cities referenced on some narratives.) The February floods result fTom an early thaw of snow and an accompanying heavy rain that result in quick runoffs over the still fTozen ground. They commonly result in flash floods with advance warning of less than 24 hours. The floods are often exacerbated by ice jams resulting fTom the thawing and breaking up of ice in the rivers and streams. If there has been significant melting, it may only take small rainfalls to produce February and early March floods. Damages fTom late winter floods are almost always limited to property located near rivers. Spring floods typically result fTom the melting of snow and typically are forecast well in advance. The National Weather Service provides advance flood estimates as much as a month in advance. However, these forecasts are revised with unanticipated temperatures and/or rainfall. Spring floods typically result in "repeat" property damages that are properties that receive similar damage fTom every flood of significance and delay the planting of crops or damage early crops. Summer floods result fTom well above normal precipitation over an extended period of time and/or extremely heavy rainfall. Those occurring over the extended wet weather may allow for several days to possibly two weeks notice of floods. Those occurring after extremely heavy rainfalls typièally result in advance warning of less than 24 hours. Damages fTom summer floods may include any property as heavy rains of this magnitude create heavy ground saturation and commonly flood basements. They may cause significant crop damages as well depending on the maturity of crops, The City of Dubuque paid out no citizen claims due to flooding between January 2000 and May 30, 2003. However, the City has incurred infTastructure damage as a result of floods. Listed below are the damage costs that the City of Dubuque incurred for infTastructure repairs as a result of the storms and floods since 1993. 3 Dubuque Pre-Disaster Mitigation Plan July 1993 and June 2002 Floods combined Streets $ 73,454 Streets $ 200,139 Storm Sewers $ 36,331 Sanitary Sewers $ 248,567 May 1999 Flood Streets Sewers WPC Plant Párks $ 200,139 $111,719 $ 39,891 $ 21,696 April 2001 Flood FloodwalIlShoreline Repairs $ 202,000 Repetitive Loss Information The National Flood Insurance Program maintains records of all payments made as a result of flood damage. The NFlP records show that one property sustained repetitive loss damages and received payments resulting fTom floods in May 1999 and June 2002. The total building payments were $2,543. The building value is listed at $86,176, thus it was not substantially damaged as a result of floods. Payments totaling $8,581 were made for contents damage resulting from these floods. FEMA National Flood Insurance- Insurance Claims and Policy Statistics As of September 30, 2002, the City of Dubuque had filed 13 flood insurance claims and received total insurance claim payments of$37,746.95 resulting fTom the June 2002 floods. Flood Insurance Information The most recent Flood Insurance Study was revised by the Federal Emergency Management Agency on September 6, 1989. See Appendix C for a copy of the study. The current Dubuque, NFlP Community Number 195180 (index plus six panels) map was revised September 6, 1989. See Appendix D for a copy of the FIRM map. Preventative Actions Taken The City of Dubuque submitted 404 Hazard Mitigation Grant Program applications to the Iowa Emergency Management Division (IEMO) in Des Moines, IA in 1999 and 2002. The.initial 1999 application consisted of the acquisition and demolition of one flood damaged residential structure fTom property located in the NFlP 1O0-year Floodplain. The City's second application was submitted for acquisition and demolition of 6 properties as a result of the June 2002 flooding, desiguated as disaster declaration #1420. Due to funding limitations, the 4 Dubuque Pre-Disaster Mitigation Plan .~.- ,. " ,..., application was approved to provide funding at this time for acquisition and demolition of 3 flood-damaged properties. This project is ongoing at the time of this document. The City of Dubuque is protected fTom Mississippi River flooding by a floodwall constructed in the late 1960s. The City routinely monitors and maintains the flood wall system. Tornadoes Tornadoes are relatively common in Iowa, including Dubuque County, particularly in spring and summer. The conditions that produce a "tornadic thunderstorm" (a storm that produces a tornado) exist when warm, moist air gets trapped beneath a stable layer of cold, dry air by an intervening layer of warm, dry air. This stratified sandwich of air is called an inversion. Tornadoes have been known to lift and move huge objects, destroy or move whole buildings long distances, and siphon large volumes fTom bodies of water. People living in manufactured or mobile homes are most exposed to damage fTom tornadoes because they typically do not have basements to where they may seek shelter. Even if anchored, mobile homes do not withstand high wind speeds as well as permanent, site built structures. Most new home parks provide storm shelters for their residents. However, many older parks do not have shelters available. The Fujita Tornado Scale measures tornado severity. The Fujita Scale assigns a numerical value based on wind speeds and categorizes tornadoes fTom 0 to 5. The letter "F" often precedes the numerical value. Scale values above F5 are not used because wind speeds above 318 MPH are unlikely. See Appendix E, Table E-I for the Fujita Scale and the wind speeds associated with tornadoes using the Fujita Scale. Newspaper records indicate that the September 10, 1970 tornado resulted in millions of dollars in property damage throughout its path. The June 1993 tornado caused property damage and injuries in Dubuque. The July 8, 1993 tornado caused over 2 million dollars in damage to Dubuque County. In addition, the July 4, 1994 tornado caused extensive property damage to Dubuque County. The National Oceanic and Atmospheric Administration (NOAA) also records tornadoes and associated damages. See Appendix E, Table E-2 for NOAA recorded tornadoes in Dubuque County. The data provides a countywide listing of tornadoes. Note that the data in the table was gathered fTom the u.S. Department of CommercelNOAA was discussed with the PDM Planning Team and is considered to be conclusive information. Preventative Actions Taken Most tornadoes touch down in Iowa during the months of March, April, May and June. The most important way individuals can prevent being injured is to be alert to the onset of severe weather. 5 Dubuque Pre-Disaster Mitigation Plan In the event of a tornado, the National Weather Service issues a watch or warning. This information is disseminated through State Radio warning points. The warning point for the City of Dubuque is Cedar Falls, IA. Cedar Falls staff contacts the Dubuque City/County Law Enforcement Center regarding warnings. The dispatchers at the Dubuque City/County Law Enforcement Center notifY all Fire Departments, Law Enforcement and Emergency Operations Center Staff (EOG). The dispatchers receive backup of teletype information fTom the National Weather Service. The EOC has access to National Weather Service radar and local media radar. Information is disseminated to all agencies through their local 800 Megahertz Radio System. KDTH (1370 AM) is the local radio station for the emergency alert system and notifies listeners of storm information. The City of Dubuque has several warning devices including outdoor warning sirens, NOAA (National Oceanic and Atmospheric Administration) weather radios, cable TV interruption through the EAS (Emergency Activation System) and has a severe weather plan and a winter weather plan. The National Weather Service also has the capability to provide cable interruption service to all cable subscribers through the EOC system providing alert siguals on their television screens for weather warnings. High Winds The city has experienced property damage in the last 30 years fTom winds blowing trees down on houses. These winds are currently referred to as straight line winds. The National Weather Service (NWS) defmes them as winds in excess of 58 miles per hour and not associated with a tornado or tornadic action. The NWS refers to them in the definition of severe thunderstorm, although they are not necessarily part of a thunderstorm. The NWS issues a high wind warning when sustained winds in excess of 40 miles per hour for more than one hour or 58+ miles per hour winds are anticipated to be present for any duration. A wind advisory is issued when sustained winds of 30 miles per hour for at least one hour or more or gusts of 45 miles per hour or greater are anticipated. The city has lost trees fTom high winds. No known loss of life or injuries resulted fTom these winds. See Appendix F for the NOAA listing of recorded high wind events between 1957 and February 2003. While hurricanes are not experienced in the Midwest, wind gusts of 100 miles per hour or greater are the equivalent of a Category 2 hurricane. Preventative Actions Taken Individuals are alerted to the onset of high winds through the National Weather Service. The National Weather Service receives this information as it is disseminated through State Radio warning points. The State Radio warning point for the City of Dubuque is Cedar Falls, IA. Dispatchers at the Dubuque City/County Law Enforcement Center notifY all Fire Departments, Law Enforcement, and Emergency Operations Center Staff (EOC). The dispatchers receive backup of teletype information fTom the National Weather Service. The EOC has access to National Weather Service radar, local media radar and DTN Storm Sentry. 6 Dubuque Pre-Disaster Mitigation Plan In addition, the Dubuque County Emergency Management Services provides weather related information to the community. Dubuque County activates the cable interruption network to all cable subscribers and provides alert siguals on their television screens. The NWS issues a wind advisory when sustained winds are forecast to be over 30 miles per hour and/or gusts of over 45 miles per hour for 3 hours or more. The NWS states that winds of these magnitudes may cause minor property damage without extra precautions. They recommend securing lawn furniture, garbage cans or other objects which could be blown about by the wind. Further they warn motorists against driving high profile vehicles until the high winds diminish. In addition, the City of Dubuque requires that power lines in new subdivisions be buried. Thunderstorms The National Weather Service (NWS) states that a "severe" thunderstorm is any storm that produces one or more of the following elements: . A tornado . Damaging winds, or winds measured 58 miles per hour or more . Hail three quarters (3/4) of an inch in diameter or larger. Most thunderstorms do not result in a tornado, damaging winds or hail. However, the City has had numerous thunderstorms in the past 30 years with minimal damage to the city. The extent of damage was a loss of trees or trees blown over on some of the residential structures. See Appendix G, Table G-1 for NOAA recorded thunderstorms in Dubuque County. Note: Hailstorms are reported independent of thunderstorms of the hailstorms by NOAA. See page 8 and Appendix H, Table H for NOAA recorded hailstorms. There has been no major (1/4 of city or more) power outages in the last 50 years in the City of Dubuque. The likelihood of this is quite small as no more than 1,800 buildings are on any single breaker or switch. It would require a catastrophic failure, such as a breech of the floodwall during a major flood to knock out the main plant and switches all at the same time. Alliant's first notice of an electrical service outage is often received by Alliant's Call Center in Centerville, Iowa fTom a citizen or police department dispatcher. (Alliant provides electric service to the City of Dubuque.) As soon as the problem has been identified as an outage, Centerville contacts Alliant's Service Distribution Center in Cedar Rapids. If the outage has occurred after normal working hours, the Cedar Rapids staff will contact Dubuque's Alliant workers at home and assign work tasks over the phone. If the outage occurs during regular work hours, Cedar Rapids notifies the Dubuque service department and empowers them to assigu remedial tasks. Notice to the media and public regarding power outages are handled solely by Alliant's corporate communications center in Cedar Rapids. 7 Dubuque Pre-Disaster Mitigation Plan Preventative Actions Taken Individuals are alerted to the onset of severe rain and thunderstorms by the National Weather Service through local news media. The alerts include wind advisories and warnings as noted above. The National Weather Service receives this information as it is disseminated through State Radio warning points. The State Radio warning point for the City of Dubuque is in Cedar Falls, IA. Cedar Falls contacts the Dubuque City/County Law Enforcement Center regarding warnings. The dispatchers at the Dubuque City/County Law Enforcement Center notifY all county Fire Departments, Law Enforcement and Emergency Operations Center Staff (EOC). The dispatchers receive backup of teletype information fTom the National Weather Service. The EOC has access to National Weather Service radar and local media radar. All information is disseminated to all agencies through their local 800 Megahertz Radio System. KDTH is the local AM radio station for the emergency alert system and notifies listeners of storm information. The City of Dubuque has several means available to advise residents of severe weather. These include warning devices including outdoor warning sirens, NOAA (National Oceanic and Atmospheric Administration) weather radios, cable TV mterruption through the EAS (Emergency Activation System), and has a severe weather plan and a winter weather plan. The National Weather Service has the capability to provide cable interruption service to all cable subscribers through the EOC system providing alert siguals on their television screens for weather warnings. Hailstorms Hailstorms are closely connected with thunderstorms. Hailstorms are most likely to occur in spring while thunderstorms occur in summer. Hail consists of round balls of ice that fall fTom the clouds during some thunderstorms. Hailstones range fTom size of peas up to the size of baseballs and larger. Large hailstones are dangerous to humans ánd animals. Severe hailstorms cause heavy damage to buildings, particularly windows, and crops. The August 1994 hailstorm with 4Y2-inch hail was the most severe hailstorm recorded in the City of Dubuque with total damages estimated at $100 million. See Appendix H, Table H for NOAA recorded hailstorms in Dubuque County. Note: the Table in Appendix H lists the August 19, 1994 storm with $5 million dollars in damage. The PDM Planning Team confirmed the inaccuracy of that report. Preventative Actions Taken Individuals are alerted hailstorms by the National Weather Service through local media, including radio and the cable interruption network. Typically hail storms occur with minimal or no warning. Whenever possible, significant weather related information is relayed to public safety agencies fTom the Dubuque County dispatch center and local dispatch. 8 Dubuque Pre-Disaster Mitigation Plan -~ ~M -~ -'"- ----,~----- Severe Winter Storms Dubuque has numerous snowfalls every winter. However, it is rare that snowstorms result in damages beyond those occurring in traffic accidents. Heavy snows limit travel and require plowing and/or snow removal fTom city streets. Commonly these storms include strong winds resulting in the blowing and drifting of snow and dangerous wind chills. Ice storms cause greater damages as the weight of ice breaks power lines and trees. Power outages are common following heavy ice storms. Either type of winter storm may result in injuries and/or deaths, some of which are unreported or have no estimates available or do not list the storm as the direct cause of it. See Appendix I, Table I for NOAA recorded winter storms in Dubuque County. Preventative Actions Taken Individuals are alerted of severe winter storms by the National Weather Service through local media, including radio and the cable interruption network. The NWS issues a variety of winter storm alerts that include advisories and warnings dependent on amounts of snowfall, wind, ice and other conditions. Typically alerts are given for storms predicting at least a four-inch snowfall, 'l'.-inch of ice or winds of at least 35 miles per hour. The City of Dubuque's Street/Sewer Maintenance Supervisor assessed weather reports and if it is determined that storms are likely, the use of anti-icing technology, corrosion inhibited deicer or salt brine will be used on major arterials and bridges in Dubuque. The City of Dubuque will declare a winter storm emergency in the event of heavy snow and recommends that no non-emergency travel is carried out. In addition, the City may implement a snow emergency ordinance that requires alternate side parking to aid in the removal of the snow. Hazardous Materials and Hnman-Made Hazards In a three and one-half year period fTom January 1, 2000 to May 30, 2003 the Dubuque Fire Department responded to a total of 466 hazardous material incidents. The vast majority of these were minor fluid spills fTom automobiles. However, several major natural gas leaks occurred involving large gas mains as welL The Dubuque Fire Department responded to a lOOO-gallon spill of fertilizer on January 7, 2003, and a hydrogen chloride leak at a local manufacturing facility on August 14, 2000. In addition, there have been many responses following the discoveries of methamphetarnines (meth) labs. The City of Dubuque and Dubuque County work jointly in locating meth labs in the City of Dubuque and Dubuque County. The number ofmeth labs that have been located in the City of Dubuque since 2000 appears to be decreasing slightly as a result of these efforts. 9 Dubuque Pre-Disaster Mitigation Plan 2000:29 2001: 19 2002: 16 2003 to May 31: 8 Due to the presence of U.S. Highways 20,52,61 and 151 and railroad lines running through Dubuque, there is the potential for accidents producing fire, flying debris and/or chemical spills. The Dubuque Hazardous Materials Team has responded to major hazardous materials spills created as a result of vehicular accidents in the areas bordering the city. Preventative Actions Taken The City of Dubuque Fire Department has a Hazardous Materials Team. The Hazardous Materials Team provides Hazardous Materials Response to all of Dubuque County through a 28E Agreement. The team responds to all hazardous materials calls as a result of9/l1. In addition, the City and county are working jointly to search out meth labs as noted above. Earthquakes Earthquakes are a potential disaster faced by the City of Dubuque. Although this is a remote possibility, it does exist. According to the Iowa Geological Survev, Plum Creek River Fault Zone and Structural and Stratigraphic Framework of Eastern Iowa study volume number 13, printed in 1985, there are several areas with faults in Iowa. The two faults that could affect Dubuque are the Plum River Fault Zone and the Fayette Structural Zone. The Fayette structural Zone runs through Blackhawk County, starting north of the city of Evansdale, IA toward the city of Oe1wein, IA in Fayette County running at a diagonal fTom the southwest to the northeast. The Plum River Fault Zone is south of Cedar Rapids, IA running east towards Rockford, II.. Loras College in Dubuque has a functioning seismograph and records all seismic activity in the area. Iowa has experienced only minor earthquake activity in its recorded history. The great New Madrid, MO earthquakes of 181l-1812, centered over the New Madrid Fault zone that runs through southern Missouri and lllinois, were the first reported felt in Iowa. However, the absence of historical records prevents an accurate assessment of the actual effects in Iowa fTom these earthquakes. Earthquakes were felt through most of Iowa, particularly the westem portions of the state on July 3, 1857, October 9, 1872 and November 15, 1877. An earthquake recorded on March 1, 1935, centered in southeastern Nebraska was felt in western Iowa. Dubuque County, along with the eastem portion of Iowa felt ground movement in an 1895 earthquake centered near Charleston, MO and again on April 13, 1905. Since 1800, only one registered seismic event has occurred in Iowa. This event took place near the City of Dubuque on November 8, 1938 and registered a three (3) on the Richter scale. However none of these caused serious damage. Dubuque also felt earthquake movement on October 20, 1965 with an eastern Missouri earthquake and again on November 9, 1968. 10 Dubuque Pre-Disaster Mitigation Plan --,-~- - Preventative Actions Taken The City of Dubuque has building codes in place governing construction practices. There is a less than 1 % chance of an earthquake occurring in the City of Dubuque Wild Fires Inclnding Prairie and Grass Fires The Dubuque Fire Department responded to ninety-two wild land fire incidents between January 1, 2000 and May 30,2003. Most of these required only a small response in apparatus and personnel. The total loss of these incidents is estimated at $1,000. Preventative Actions Taken The City of Dubuque has permanent burning bans. The Dubuque Fire Department may do control bums to lessen the potential for grass fires. Extreme Temperatures Summer weather is a potential hazard to the City's residents. Temperature extremes and humidity faced by Iowans in July and August result in dangerous conditions to humans and animals. Extreme heat can kill those that are not prepared. The very young, very old, sick, or infirm residents have the greatest riskto extreme heat. Conversely, winter can bring extremely cold temperatures and wind chills. Of particular concern are homeless persons and others required to be outdoors for extended period of time along with animals that must remain outdoors. Since 1995, NOAA recorded 3 extreme high and 7 extreme wind chill/cold data. Table J in Appendix J details the recorded extreme temperature events. Preventative Actions Taken The Finley Hospital and Mercy Medical Center will offer hospital rooms to persons without air conditioning during times of extreme heat. In addition, Operation: New View Community Action Agency makes fans to lower income households in the City of Dubuque during periods of extreme heat. The Rescue Mission and other shelters are available to homeless persons throughout the year and generally see an increase in residents during the cold winter months. 11 Dubuque Pre-Disaster Mitigation Plan Community Profile (Community Assets) Community Population The City of DUbuque experienced significant population growth in the 1950s and 60s with 14% and 10% respectively, considerably higher than the state's growth rate. The 1970s saw virtually no change while the state grew by 3.1%. The decade of the 80s saw decreases statewide with the Farm Crisis. The City lost 7.7% of its population and the state lost 4.7%. The 2000 census shows the City had a minimal increase of 0.3% (148 persons) and the state grew by 5.4%. Table K-1 in Appendix K shows that the City has been very slowly decreasing in its percent of the total state population since 1970. The 2005 and 2010 projections for the City of Dubuque are based on population estimates for Dubuque County. There are no population estimates available for individual cities. The Table does not show that the City has decreased in its percent of the total Dubuque County population fTom 66.5% in 1980 and 66.6% in 1990 to 64.7% in 2000. The PDM Planning Team noted that the City has a significant Hispanic population who speak Spanish as their primary language or may not speak English at all. The 2000 census lists shows that in the population of persons age 5 years and over there are 2,480 who speak a language other than English. Of this number, the largest single language is Spanish consisting of 1,172 persons who speak Spanish at home. Of these person, 494 said the speak English less than "very well." Community Structnres Table K-2 in Appendix K below discusses the age of the housing stock of Dubuque. The city has 37.3% of its housing units built in 1939 or before, 34.9% built between 1940 and 1969, and 19.26% built between 1970 and 1989. The census shows that 2,031 housing units were constructed in the 1990s representing 8.5% of the City's housing stock. Construction methods, safety requirements, along with engineering and design of homes have improved over the past decades. The City of Dubuque currently utilizes the 2000 International Residential Code as the minimum construction standards for all residential construction. The City utilizes the Uniform Building Code for the construction standards for non-residential buildings. The City does have a number of structures located in the lOa-year floodplain. The majority of these are residential units constructed prior to the adoption of the City's floodplain ordinance. The majority are located along the floodplain branches of the Catfish Creek scattered throughout the City. The City acquired one of these properties in 1999 and three additional properties in 2003. In addition, there are some 540 homes in the north end area of the City in the Central AvenuelWhite and Jackson St. corridor roughly north of 22nd St. and south of 32nd St. that has experienced flooding as a result of overcharged storm sewers following extremely heavy rains. The City is currently (June 2003) working with an engineering consultant to design an open drainage ditch storm water system. The City hopes the project will eliminate the flooding that has been experienced in this area. The project will require the purchase of approximately 70 homes and relocation of the owners and tenants. 12 Dubuque Pre-Disaster Mitigation Plan C~._---.- ~ _._~-- The table below lists the numbers and percentages of structures lotated in the City of Dubuque. The exact numbers and values of structures located in floodplains are not available at the time of this document. As noted above, the City has acquired four residential properties fTom the floodplain and is working to address the properties in the north end that experience flooding and are not located in a floodplain. The non-floodplain properties are not listed with those in a hazard area.

A critical facility is defined by FEMA as a facility in either the public or private sector that provides essential products and services to the general public, is otherwise necessary to preserve the welfare and quality of life in the City (and surrounding area), and fulfills important public safety, emergency response, and/or disaster recovery functions. These facilities included such things as hospitals and cliuics, transportation systems, lifeline utility systems, high potential loss areas and hazardous material facilities. Other vital facilities include transportation routes, especially bridges over rivers and utility services, such as electric power. Damage to these facilities can impact the delivery of vital services, cause' greater damages to other sections of the community, and/or put special, vulnerable populations at risk in the case of a major hazard event. FEMA defines a vulnerable population as elderly, especially those who require special response assistance, areas of high density population, including such facilities as childcare centers, non-English speaking residents, and others. These facilities must be closely monitored throughout and following storm events to assure the greatest safety precautions are being maintained and responses to events are handled quickly and efficiently. The task force determined the following facilities in Dubuque are critical facilities. See Appendix L and M for maps oflocations of Critical Facilities and Vulnerable Populations. Public facilities appear in bold type.

Thirty eight of the shelters are located in the City of Dubuque. See Appendix N for a list of those facilities. In addition, persons residing in properties located in the floodplain are especially susceptible to injury and damage. There is no warning system in place to provide advance notification of flooding to those persons. 17 Dubuque Pre-Disaster Mitigation Plan Description of Land Uses The City of Dubuque's land uses are residential, office, commercial, industrial, institutional, agricultural and open space. Residential The City's primary land use is residential and is found throughout the community. A large percentage of Dubuque's older residential properties are located in the Central Ave./Jackson Street corridors. Many of these developed as exclusively residential neighborhoods; however, many are currently interspersed with commercial and industrial development. There is no designated floodplain in this area; however this area has experienced flooding as a result of overcharges of the storm sewer system. Other older residential development is also located in the hill area directly west of the city's bluff line. This area is primarily residential; however, again there are commercial nodes interspersed. The City continues to grow to the west and south with newer residential development primarily located in these areas. Within these new neighborhoods, there are floodplains areas at the rear of lots; however there are no residential structures located in the floodplain. There are instances of individual residential properties and structures constructed prior to the floodplain desiguations and/or annexed into the City that are located within a floodplain. Commercial Commercial properties are primarily located along three corridors and at multiple nodes throughout the community. The first primary commercial corridor is along Dodge Street (US Highway 20) fTom Devon Drive to Seippel Road. There are a number of big-box commercial developments and strip commercial centers along this corridor. None of the commercial structures along this corridor are located in a floodplain. However, some of the lots extend into the Catfish Creek drainage and are technically located in the floodway. Because of the extreme topography change between the level commercial pads with buildings and associated parking lots and the floodplain below, it is not likely that additional commercial development will occur on the slopes or be proposed for development in the floodplain. There are several businesses located along the Dodge Street corridor just off of Cedar Cross Road that are located in a floodplain and are allowed to remain under a grandfather clause. The second primary commercial corridor is John F. Kennedy Road fTom University Avenue to Kaufinann Avenue. The businesses located in this area are primarily stand-alone commercial fTanchises and small strip mall centers. There are no structures located in the floodplain; however, some of the rear lots may again extend into a floodplain but are not likely to be developed. 18 Dubuque Pre-Disaster Mitigation Plan, ~"'----, The third primary commercial corridor is located along the Central AvenuelWhite Street (US Highway 52) corridor fTom 4th Street to 24th Street. This corridor consists of multi-story commercial buildings, many with residential use above, located in an older historic part of the city. None of these businesses are located in a floodplain. Two other large pockets of commercial development include the new commercial stand-alone and strip development located at the northwest corner of Asbury Road and Northwest Arterial and the Old Main/Cable Car Square districts. None of the structures in these areas are located in a floodplain. There are several other commercial nodes throughout the community, including a small commercial node at the intersection of Asbury Road and University Avenue, 32nd Street and Central Avenue, University Avenue and the hill area, and at the intersection of Asbury Road and Carter Road. None of these commercial properties are within a floodplain. Industrial Industrial properties are located in the older downtown area, fTom 4th Street to 20th Street. This is mixed use area with some large industrial users interspersed with small commercial and residential uses. None of these properties are located in the flood plain. Included in this area is the Kerper Boulevard industrial park with mostly newer, large industrial buildings. These businesses are protected by the floodwall and therefore not in a designated floodplain. There is another downtown industrial area located south of the Julien Dubuque Bridge (US Highway 20 over the Mississippi River) along South Main Street. This area is not located in a floodplain. The City has several new industrial parks. The Dubuque Data Technology Park is located at Dubuque's southern entrance at the intersection of Highway 61/151 and Lake Eleanor Road. A small portion of this park is located in a floodplain; however there are no structures in the floodplain area. The Dubuque Industrial Center is located along Chavenelle Road at its intersection with the Northwest Arterial. There is a portion of the south part of this industrial park that is located in a floodplain; however there are no structures in the floodplain area. The Dubuque Industrial Center West is located on the Chavenelle Road Extension at its intersection with Seippel Road. This area has several new industries and a small portion of this property is located in the floodplain but has no structures and is not likely to be developed. Development Trends The last three years of development in Dubuque can be characterized as a balance between commercial, industrial and residential. In addition, the local colleges have also made significant on-campus additions. The community has seen a significant level of new development that has provided new housing options, commercial opportunities and industrial expansions that have allowed the Dubuque area to grow despite national economic trends. 19 Dubuque Pre-Disaster Mitigation Plan Recent Developments - Subdivisions Since January 2000, eight new residential developments have been proposed and/or are being built in the city of Dubuque. In 2000, Crescent Heights, Oak Meadow II, Pine Knolls, and Tumberry were approved. In 2001, Jaeger Heights, Arbor Estates and Harvest View Estates were approved. In 2003, Eagle Valley and Wynstone have been proposed and are currently preparing improvement plans and final plats. Together, these developments create approximately 370 building lots and 165 condominium units. Recent Annexations The city of Dubuque has seen a significant amount of annexations in recent years. However, since January 1, 2000, there have been only three annexations of significant size; two are located near the intersections of the comer of Seippel Rd and Old Highway Road at. the west edge of the City and one located on the west side of John F. Kennedy Road at the northwest City limits. These annexations totaled approximately 70 acres. Commercial Developments Since January 1, 2000, the city has seen a number of major commercial developments. These include the developments at the Port of Dubuque, the first phase of Asbury Plaza Shopping Center, the Super Menard's on US Highway 20, Best Buy Superstore located at the northwest comer of Wacker Drive and US Highway 20 and the Walgreen's Store at the southeast corner of Asbury and Kennedy Roads. Industrial Developments The City has seen industrial development over the past several years. This includes the construction of the McGraw Hill distribution center, Kirchoff Distributing facility, Riverside Tractor-Trailer facility in the downtown area and the Giese Mfg. Co. and Adams Co. relocating to the Dubuque Industrial Center West. Other Development Trends The local colleges have seen significant on-campus additions, including Loras College and the University of Dubuque, both adding new libraries and student apartments. The University of Dubuque has also added seminary housing along Collins Street. Other Development All commercial, industrial and multi-family development requires multi-department site plan review coordinated by the City's Planning Services Department. Site plan requirements mandate that storm water calculations and mitigation measures be provided by the applicant. The City is also working on a joint City/County review for site plans, which will enable the City to review funge area development for storm water detention. 20 Dubuque Pre-Disaster Mitigation Plan "-.-- Comprehensive Land Use Plan The City of Dubuque's comprehensive land use plan is the community's guide to future development of public policies and decision making. The Comprehensive Plan is not an ordinance. . It reflects the long-range goals and objectives developed over several years through input at public workshops and hearings. The Comprehensive Plan was adopted in two phases in 1994 and 1995 and was updated in 2000-2002. As a guide for the community's future, the City of Dubuque will use the plan to shape its policies and decisions in areas where City government has authority and influence. Implementation of many elements of this plan involves other community players such as health care providers, educational institutions, human services agencies, private businesses and nonprofit organizations. The elements of the Comprehensive Plan include: . Physical Environment- Land Use and Urban Desigu, Transportation, InfTastructure, and Environmental Quality. . Economic Environment- City Fiscal and Economic Development. . Social Environment- Health, Housing, Human Services, Education, Cultural Arts, Recreation, Public Safety, and Diversity. 21 Dubuque Pre-Disaster Mitigation Plan Hazard Analysis and Ratings of Hazards The PDM Planning Team reviewed all identified hazards and assigued values to each hazard utilizing the following rating system.

In addition to the raw scores assigued to each of the hazards by the planning team, an additional cascading factor value was applied. The cascading value was based on the potential for a given hazard to result in another hazard. For example, a thunderstorm has a low probability that it would result in a flood. Thus a score of "I" was added in the cascading value space, following horizontally fTom the hazard to the (vertical) column of the resulting hazard. Another example is a tornado hazard that always results in high winds, thus a score of "4" in the high wind column. However, a flood will not result in a tornado, resulting in a "0" in the tomado column in the flood category. The numbers were then totaled in each direction and the grand total of the column and row was entered in the Cascading Value column for each hazard at the right side of the Table. Table 3 - Hazard Matrix with Cascadin2 Values High Thunder- Winter Human- Wild Earth- Ex!.

The next hazards in order are high winds, thunderstorms and human-made. The values associated with floods, wild fifes, extreme temperatures, tornados and earthquake are decreasingly lower. Based on the City's history of hazards over the past 25 years, the matrix appears to be very reasonable. The greatest damage fTom a single event was the result of a 1994 hailstorm that resulted in an estimated $100,000,000 in total damage including structures and personal property including automobiles. However, on an annual basis the greatest expenditure of funds is the result of snow removaL The snow removal costs vary widely on an annual basis due to the fluctuations in the numbers of snow storms. The greatest costs associated with the winter storms are those involving ice storms. In general the area is not in the "ice belt"; however the City commonly experiences an average of one ice storm per winter. The next major threat is that of thunderstorms. The greatest threat of these storms is closely tied to the flood hazard. Storms that result in flash floods have become an increasing concern in the City over the past ten to fifteen years. The City has seen an increase of flash floods as a combined result of unusually heavy and brief rainfalls, development and fann practices. The developments result in a faster runoff fTom roofs and paved areas than is experienced fTom many open fields and other uses. The installation of field drain tiles also result in a faster runoff of water than previously experienced. The City continues to address the development issues and comment on fTinge area developments. The human-made disasters are generally the result of vehicular and construction accidents and the discovery of meth labs. The City continues to work at improving the safety of its transportation systems. The potential hazards as a result of construction accidents will need to be further addressed. The City continues to work with Dubuque County in a joint effort to uncover and eliminate meth labs. The construction of a flood wall in the late 1960s eliminated the flooding previously experienced as a result of Mississippi River flooding. However, as noted above, the flash floods are becoming an increasingly greater threat to the City. The potential threats that result fTom thè remainder of the hazards are lower than the first grouping. The City has mitigation equipment and procedures in place to address much of the threat fTom these hazards and continues to work with outside agencies and organizations to provide appropriate responses. The planning team reviewed the results of the Hazard Analysis and Ratings along with the Matrix of Cascading Values. Based on this information, the planning team established the following overall goals with objectives to be accomplished in each of the identified hazard categories. The team focused more attention to the higher rated hazards that appear to pose the greatest threats to the community. 41 Dubuque Pre-Disaster Mitigation Plan Pre-Disaster Mitigation Goals Floods: Minimize potential for loss of life, injury and fnture damage resulting from floods.

Analysis: Educational opportunities and orientation programs for City Council members who would act in the absence of the mayor would provide necessary back-up personnel to provide overall direction if required to do so in the absence of the mayor. Priority: Estimated Costs: Timeline: Responsible Party: Activity #3: Medium Open FY04 City Manager's Office Provide ongoing community awareness and education programs. Analysis: There may be a need to make the public better aware of community preparedness and appropriate actions to take to maintain public safety in the event of any potential threat or hazard in the community. This could include the development of a public awareness campaigu, including educational programming, marketing, public service announcements and advertising to inform the public regarding community preparedness. This includes actions to take, appropriate precautions, and other preparedness options for 54 Dubuque Pre-Disaster Mitigation Plan hazards of any variety. The campaign would include printirig and distributing pamphlets and brochures, using newspaper, television, and radio to disseminate information, City Channel 8, and City Focus through the Public Information Office. Additional information may be placed on the City of Dubuque website and linking to Dubuque365.com and/or other appropriate websites. Other dissemination vehicles include involving the Neighborhood Development Specialist, neighborhood newsletters and public service announcements. Priority: Medium Estimated Costs: $1,500 (staff time and materials per campaigu) Timeline: FY04 Responsible Party: Public Information Office Funding of Mitigation Activities The following table depicts the proposed mitigation activities in an easily read format. The table includes the proposed activities in prioritized order within the identified hazards. In addition, the estimated cost and proposed sources of funds, if available, are listed. The City is actively working on each of the High rated activities. The estimated costs are based on previous planning documents or plans currently on file with the City.

The PDM Planning Team will recommend the following strategies be utilized to evaluate and maintain the PDM planning process. Involvement of the Pnblic: 1. Continue to utilize the local access cable channel and City website to post and provide information to residents. 2. Maintain open-door policies at City Hall to continue open lines of communication between City staff and the public including, but not limited to utilizing tools such as surveys and City Expo. 3. Discuss PDM Plan at regular City Council meetings, including solicitation of public input through a public hearing at time ofPDM Plan adoption and other regular informal time set aside in all council meetings for public input. 4. In the event of an identified or previously unidentified hazard the City will request public comments and input into the identification of the hazard and goals and objectives necessary to address the hazard. Consistent with Community Goals: 1. Maintain public safety as the primary goal of the City in regard and response to all hazards including the ongoing incorporation of security procedures into the operating protocol and equipment upgrades in the City's CIP. 2. Continue to maintain and update the Multi-Hazard Plan to assure planned responses are in place and new developments are addressed. 3. Continue to comply with the requirements of the Dubuque floodplain ordinance and National Flood Insurance Program. 4. Continue to address flooding issues in non-floodplain areas to reduce or eliminate flooding. Cost Effectiveness: 1. Consult with IEMD staff on the costlbenefit ratio of potential flood buyout projects to assure that projects have positive projections. 2. Continue to work with engineering consultants to determine costlbenefit ratios of proposed flooding mitigation projects in the non-floodplain areas in the City. Technical Feasibility: 1. Continue to work with engineering consultants to determine technical feasibility of proposed mitigation projects in the City. 59 Dubuque Pre-Disaster Mitigation Plan Consistent with Community Profile, Hazard Analysis and Risk Assessment: 1. City staff will annually review the PDM Plan to validate prior profiles, evaluation and analysis of hazards and risks and report any necessary revisions to the City Council for approval. Identify Funding Sources: 1. Work with appropriate agencies to identify potential sources of funding for mitigation projects. The sources include, but are not limited to FEMA, Iowa Emergency Management Division, Anny Corp of Engineers, Community Development Block Grant (CDBG) program, Iowa Department of Natural Resources and others. 2. Continue to include mitigation projects in the Dubuque Capital Improvements Plan. Select and Prioritize Mitigation Measures: 1. Select and recommend to City Council all "High" rated goals and objectives for implementation and/or continuation within the next fiscal year. 2. Refer "Medium" and "Low" priority goals and objectives to City staff and public utilities (e.g.: Alliant Electric Co.) for ongoing activities and maintenance. Monitoring, Evaluating and Updating of the PDM Plan The City Manager's office will review the PDM Plan focusing on the goals, objectives and timelines of the Plan and a summary report of any recommended revisions will be provided to the City Manager who will forward recommendations to the City Council in November of each year. The goals, objectives and timelines will be discussed with directions given by the City Council to the City Manager for the inclusion of projects into the following fiscal year budget and/or revisions of the PDM Plan. In addition, in the event of any identified or previously unidentified hazard in the City, the department directors will review the PDM Plan and make any recommendations to the City Manager for revisions or updates to the PDM Plan. The City Manager wiIl review recommendations and forward appropriate changes to the City Council for consideration. Implementation Through Existing Programs The City Council will continue to work with the City Manager to include mitigation projects in the Capital Improvements Plan for implementation on a planned basis whenever feasible. The goals and objectives will be assessed on an annual basis in March in conjunction with the Capital Improvement Budget. The goals, objectives and time1ines will be communicated to City staff with directions given by the City Manager for the inclusion of projects into the Capital Improvements Plan for implementation. 60 Dubuque Pre-Disaster Mitigation Plan .-=---~-- Responsible Parties The Dubuque City Council is ultimately responsible for decisions related to all mitigation projects and their implementation through City funding and staff. The City Council will continue to work with the City Manager and with all other appropriate departments, the Emergency Management Coordinator and area law enforcement agencies to assure mitigation strategies and rapid and planned responses are in place in the event of a hazard in the community. Continuing Public Involvement The City Council routinely invites and involves Dubuque citizens in the planning and budgetary processes of the City of Dubuque.
