Pre Disaster Mitigation Plan RecommendationMEMORANDUM TO: FROM: SUBJECT: December 26, 2003 The Honorable Mayor and City Council Members Michael C. Van Miliigen, City Manager City of Dubuque Pre Disaster Mitigation Plan Emergency Management Coordinator Tom Berger is recommending approval of an updated Pre Disaster Mitigation Plan. The plan has been prepared by the East Central Intergovernmental Association and a local committee consisting of Council Member Dan Nicholson, Council Member Ann Michalski, Assistance City Manager Cindy Steinhauser, Fire Chief Dan Brown, Assistant Fire Chief Rick Steines, Operations and Maintenance Manager Don Vogt, Police Chief Klm Wadding, Police Lieutenant Dan Avenarius, Public Information Officer Susan Gwiasda, Associate Planner Kyle Kdtz, Assistant City Engineer Gus Psihoyos, Airport Manager Andy Perry and Emergency Management Coordinator Tom Berger. The new Pre Disaster Mitigation Plan is an update of the original Hazard Mitigation Plan that was approved by the City of Dubuque on February 4, 2002. The changes to the plan were mandated by the Pre Disaster Mitigation Act of 2000 that was implemented by the Federal Emergency Management Agency after the original plan was submitted to the Iowa Emergency Management Division. This plan was submitted in draft form in July and then revised by ECIA after a few changes were suggested by FEMA. This plan is considered Part B of our Comprehensive Emergency Management Plan and qualifies the City of Dubuque for Federal and State Assistance in a disaster. After the public hearing the approved plan will be submitted to the Iowa Homeland Security and Emergency Management Division for their approval and then forwarded on to FEMA I concur with the recommendation and respectfully request Mayor and City Council approval.

A planning team consisting of members of the City Council, representatives from City Engineering, City Planning, Police Department, Fire Department, Public Works, Ambulance, Emergency Manag~raent S~wices, Public Relations, and the regional Council of Governments. (See Appendix A for a list of team 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 finther refine the document and provide greater detail 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 future meetings to be held) for public input and comment during the drafting stages of the plan and a public heating was held on January 5, 2004 for public input prior to approval and adoption of the plan. 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 aker 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 hms 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 hi 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 any time of the year. Dubuque Pre-Disaster Mitigation Plan The Planning team identified several hazards that are addressed in this PDM Plan. The hazards were identified through the review of the previous Hazard Mitigation Plan, research of historic data from area newspapers, FIRM maps and additional GIS maps developed through the regional council of governments and valuation information from 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.

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 no~h 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 from an early thaw of snow and an accompanying heavy rain that result in quick runoffs over the still frozen ground. They commonly result in flash floods with advance warning of less than 24 hours. The floods are often exacerbated by ice jams resulting from 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 from late winter floods are almost always limited to property located near rivers. Spring floods typically result from 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 from every flood of significance and delay the planting of crops or damage early crops. Summer floods result from well above normal precipitation over an extended period of time and/or extremely heavy rainfall. Those occunfng over the extended wet weather may allow for several days to possibly two weeks notice of floods. Those occurring after extremely heavy rainfalls typically result in advance warning of less than 24 hours. Damages from summer floods may include any property as heavy rains of th/s 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 irrffastructure damage as a result of floods. Listed below are the damage costs that the City of Dubuque incurred for infras~c~e 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 $ 200,139 Sewers $111,719 WPC Plant $ 39,891 Parks $ 21,696 April 2001 Flood Floodwall/Shoreline Repairs $ 202,000 Repetitive Loss Information The National Flood Insurance Program maintains records of all payments made as a result of flood damage. The NFIP records show that one property sustained repetitive loss damages and received payments resulting from 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 from 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, NFIP Commuulty 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 (IEMD) in Des Moines, IA in 1999 and 2002. The initial 1999 application consisted of the acquisition and demolition of one flood damaged residential structure from property located in the NFIP 100-year Floodplain. The City's second application was submitted for acquisition and demolition of 6 properties as a result of the June 2002 flooding, designated as disaster declaration #1420. Due to fimding limitations, the 4 Dubuque Pre-Disaster Mitigation Plan application was approved to provide fimding 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 from 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 "tomadic 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 from bodies of water. People living in manufactured or mobile homes are most exposed to damage from 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 Tomado Scale measures tomado severity. The Fujita Scale assigns a numerical value based on wind speeds and categorizes tornadoes fi:om 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-1 for the Fujita Scale and the wind speeds associated with tornadoes using the Fujita Scale. Newspaper records indicate that the September 10, 1970 tomado 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 from the U.S. Department of Commerce/NOAA was discussed with the PDM Planning Team and is considered to be conclusive information. PreventafiveActions 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 Enforc~-nent Center notify all Fire Departments, Law Enforce~nent and Emergency Operations Center Staff (EOC). The dispatchers receive backup of teletype information from 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 Systmn. 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 signals on their television screens for weather warnings. High Winds The city has experienced property damage in the last 30 years fi.om winds blowing trees down on houses. These winds are currently referred to as straight line winds. The National Weather Service (NWS) defines them as winds in excess of 58 miles per hour and not associated with a tomado or tornadic action. The NWS refers to them in the definition of severe thunderstorm, although they are not necessarily part ofathunderstorm. TheNWS issues atfighwind 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 from high winds. No known loss of life or injuries resulted fi.om 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. PreventafiveAcfions 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 waming 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 from the National Weather Service. The EOC has access to National Weather Service radar, local media radar and DTN Storm Sentry. 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 signals on their television screens. The NWS issues a w/nd advisory when snstained winds are forecast to be over 30 miles per hour and/or gusts of over 45 m/les per hour for 3 hours or more. The NWS states that winds o£ 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 d/miulsh. 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 scnMce outage is often received by Alliant's Call Center in Centerville, Iowa from a citizen or police department dispatcher. (Alliant provides electric scnMce 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 assign remedial tasks. Notice to the media and public regarding power outages are handled solely by Alliant's corporate communications center in Cedar Rapids. 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. T~ae 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 Fails 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 fi:om the Nationai Weather Service. The EOC has access to Nationai Weather Service radar and locai 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 interruption 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 signals 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 fi:om the clouds during some thunderstorms. Hailstones range from size of peas up to the size of baseballs and larger. Large hailstones are dangerous to humans and animals. Severe hailstorms cause heavy damage to buildings, particularly windows, and crops. The August 1994 hailstorm with 4½-inch hail was the most severe hailstorm recorded in the City of Dubuque with totai 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 ?DM Planning Team confirmed the inaccuracy of that report. PreventafiveAcfions Taken Individuals are alerted hailstorms by the National Weather Service through locai 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 from the Dubuque County dispatch center and local dispatch. Dubuque Pre-Disaster Mitigation Plan 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 fi.om 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 hnes 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, ¼-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-amergency travel is carded 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 Human-Made Hazards In a three and one-half year period fi.om 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 fi.om automobiles. However, several major natural gas leaks occurred involving large gas mains as well. The Dubuque Fire Department responded to a 1000-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 methamphetamines (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 of meth 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. PreventafiveAcfions 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 of9/11. In addition, the City and county are working jointly to search out meth labs as noted above. Earthquakes Earthquakes are a potential disastcr faced by the City of Dubuque. Although this is a remote possibility, it does exist. According to the Iowa Geological Survey. 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 Oelwein, IA in Fayette County nmnlng at a diagonal from the southwest to the northeast. The Plum River Fault Zone is south of Cedar Rapids, IA nmnlng east towards Rockford, IL. 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 1811-1812, centered ovcr the New Madrid Fault zone that runs through southern Missouri and Illinois, were the first reported felt in Iowa. However, the absence of historical records prevents an accurate assessment of the actual effects in Iowa from these earthquakes. Earthquakes were felt through most of Iowa, particularly the western portions of the state on July 3, 1857, October 9, 1872 and November 15, 1877. An earthquake recorded on March i, 1935, centered in southeastern Nebraska was felt in westin Iowa. Dubuque County, along with the eastern 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 occundng in the City o£Dubuque Wild Fires Including Prairie and Grass Fires The Dubuque Fire Depamnent 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 burns 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 risk to extreme heat. Conversely, winter can bring extremely cold tempemtttres and w/nd 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. PreventativeActi~ns 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 from 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 Structures 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 conslructed in the 1990s representing 8.5% of the City's housing stock. Conslxuction 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 100-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 Avenue/White 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 The table below lists the numbers and percentages of structures located 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 from 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 recove~ functions. These facilities included such things as hospitals and clinics, 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 sm-vices, such as electric power. Damage to these facilities can impact the delivca-y 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 evants are handled quickly and efficiantly. The task force determined the following facilities in Dubuque are critical facilities. See Appandix L and M for maps of locations 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 hi 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 designations 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 commemial corridor is along Dodge Street (US Highway 20) fi:om 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 from University Avenue to Kaufmann Avenue. The businesses located in tkis area are primarily stand-alone commercial franchises 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 pr/mary commercial corridor is located along the Central Avenue/White Street (US Highway 52) corridor fi:om 4th Street to 24t~ 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 comer of Asbury Road and Northwest Arterial and the Old Ma/xffCable 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, fi:om 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 Turnberry were approved. In 2001, Jaeger Heights, Arbor Estates and Harvest Vie~v 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 Annexa~ons The city of Dubuque has seen a significant mount 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 comer 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 fringe 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 furore development of public policies and decision malting. 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 heatings. 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 commtmity 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 Design, Transportation, Infrastructure, 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 alt identified hazards and assigned values to each hazard utilizing the following rating system.

In addition to the raw scores assigned 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 "1" was added in the cascading value space, following horizontally from 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 tornado colunm in the flood category. The numbers were then totaled in each direction and the grand total of the coltmm and row was entered in the Cascading Value column for each hazard at the right side of the Table. Table 3 - Hazard Matrix with Cascading Values High Thunder- Winter Human- Wild Earth- Ext.

The next hazards in order are high winds, thunderstorms and human-made. The values associated with floods, wild fires, 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 from 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 armual 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 ra'nffalls, development and fann practices. The developments result in a faster runoff from roofs and paved areas than is experienced from many open fields and other uses. The installation of field drain tiles also result in a faster runoff of water titan previously experienced. The City cont'mues to address the development issues and comment on fringe 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 ehminated 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 from the 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 fi:om 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 future damage resulting from floods.
