Major waterways in the area include the North Racoon River, which runs along the north and east sides of the city, and Hickory Creek. Demographics Adel’s population in 2020 was 6,153. The following figure displays the historical population trend from 1860 to 2020. This figure indicates that the population of Adel increased gradually from 1860 to 2010 and saw a dramatic increase from 2010 to 2020. Increasing populations are associated with increased hazard mitigation and emergency planning requirements for development. Increasing populations can also contribute to increasing tax revenues, allowing communities to pursue additional mitigation projects. Adel’s population accounted for 6.2% of Dallas County’s population in 2020.1 Figure ADL.1: Population 1860 - 2020 Source: U.S. Census Bureau 1 United States Census Bureau. “2020 Census Redistricting Data (Public Law 94-171): P1: Race.” 466 711 989 995 1,213 1,289 1,455 1,669 1,740 1,799 2,060 2,419 2,846 3,304 3,435 3,682 6,153 0 1,000 2,000 3,000 4,000 5,000 6,000 7,000 Population Year ---PAGE BREAK--- Section Seven: City of Adel Community Profile Dallas County Hazard Mitigation Plan I 2023 5 Figure ADL.2: City of Adel ---PAGE BREAK--- Section Seven: City of Adel Community Profile 6 Dallas County Hazard Mitigation Plan I 2023 The young, elderly, and minority populations may be more vulnerable to certain hazards than other groups. Looking at Adel’s population: • 6.6% is non-white. Since 2010, Adel became more racially diverse. In 2010, 2.4% of the Adel’s population was non-white. By 2020, 6.6% was non-white.2 3 • 36.9 median age. The median age of Adel was 36.9 years old in 2020. The population grew older since 2010, when the median age was 36.4 5 Figure ADL.3: Population by Age Cohort and Sex (2020) Source: U.S. Census Bureau4 The figure above shows Adel’s population percentage broken down by sex and five-year age groups. Adel’s population is younger with a higher percentage of the population below 40 years of age. This likely indicates a growing population in the years to come. 2 United States Census Bureau. “2020 Census Redistricting Data (Public Law 94-171): P1: Race.” 3 United States Census Bureau. “2010 Census Redistricting Data (Public Law 94-171): P1: Race.” 4 United States Census Bureau. “2020 Census Bureau American Community Survey: S0101: Age and Sex.” 5 United States Census Bureau. “2010 Census Bureau American Community Survey: S0101: Age and Sex.” 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Under 5 5 to 9 10 to 14 15 to 19 20 to 24 25 to 29 30 to 34 35 to 39 40 to 44 45 to 49 50 to 54 55 to 59 60 to 64 65 to 69 70 to 74 75 to 79 80 to 84 85 & Over Percentage of the Population Years Female % Male % ---PAGE BREAK--- Section Seven: City of Adel Community Profile Dallas County Hazard Mitigation Plan I 2023 7 Employment and Economics Low-income populations, long distance commuters, and the unemployed may be more vulnerable to certain hazards than other groups. Adel’s population has: • 8.5% of people living below the poverty line. The poverty rate in Adel was lower than the state’s poverty rate (11.1%) in 2020. 6 • $66,005 median household income. Adel’s median household income in 2020 ($66,005) was about $4,200 higher than the state ($61,836). 7 • 5.3% unemployment rate. In 2020 Adel had a higher unemployment rate compared to the state • 35.7% of workers commuted 30 minutes or more to work. More workers in Adel commuted 30 minutes or more to work than workers commuting less than 15 minutes (35.7% compared to 20.5%).9 Major Employers Major employers for the city include Dallas County and Adel-DeSoto-Minburn Schools. According to the local planning team, approximately 66% of residents commute to other communities for work, including Des Moines, West Des Moines, and Urbandale. Housing The age of housing may indicate which housing units were built prior to the development of state building codes. Vacant housing stock may also be more vulnerable to hazard events if it is poorly maintained. Unoccupied housing may also suggest that future development may be less likely to occur. Communities with a substantial number of mobile homes may be more vulnerable to the impacts of high winds, tornadoes, and severe thunderstorms if those homes are not anchored correctly. Renter-occupied housing depends on the initiative of landlords for proper maintenance and retrofitting to be resilient to disasters. They are less likely than homeowners to have flood insurance, or to know their risks to flooding and other hazards. • 42% of housing built prior to 1970. Adel has a smaller share of housing built prior to 1970 than the state (42% compared to 50.4%).10 • 4.4% of housing units vacant. Since 2010, Adel’s vacancy rate decreased. In 2010 the vacancy rate was 4.7%. By 2020, 4.4% of housing units were vacant. 11 12 6 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 7 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 8 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 9 United States Census Bureau. “2020 Census Bureau American Community Survey: S0802: Means of Transportation to Work by Selected Characteristics.” 10 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 11 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 12 United States Census Bureau. “2010 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” ---PAGE BREAK--- Section Seven: City of Adel Community Profile 8 Dallas County Hazard Mitigation Plan I 2023 • 1.9% mobile and manufactured housing. The City of Adel had a smaller share of mobile and manufactured housing compared to the state (3.6%).13 • 28.5% renter-occupied. The rental rate of Adel was 28.5% in 2020. The percentage decreased since 2010, when renter occupied housing was at 42.6%.14 15 The city does host two locations with a large number of mobile homes. These sites are River Vista where there are 60 mobile homes and S. 11th St where there are 20 mobile homes. Governance A community’s governance indicates the number of boards or offices that may be available to help implement hazard mitigation actions. Adel has a mayor, a five-member city council, and the following offices. • City Manager • Clerk/Treasurer • Attorney • Chief of Police • Fire Chief • Wastewater Plant Superintendent • Water/Sewer Superintendent • Solid Waste Superintendent • Street Superintendent • City Inspector • Library Board Chairperson • Parks Superintendent • GIS/Zoning Administrator • Public Works Director Capability Assessment The capability assessment consisted of a Capability Assessment Survey completed by the jurisdiction and a review of local existing policies, regulations, plans, and the programs. The survey is used to gather information regarding the jurisdiction’s planning and regulatory capability; administrative and technical capability; fiscal capability; and educational and outreach capability. 13 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 14 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 15 United States Census Bureau. “2010 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” ---PAGE BREAK--- Section Seven: City of Adel Community Profile Dallas County Hazard Mitigation Plan I 2023 9 Table ADL.2: Capability Assessment Survey Components/Subcomponents Yes/No Planning & Regulatory Capability Comprehensive Plan Yes Capital Improvements Plan Yes Economic Development Plan Yes Emergency Operations Plan Yes Floodplain Management Plan No Storm Water Management Plan No Zoning Ordinance Yes Subdivision Regulation/Ordinance Yes Floodplain Ordinance Yes Building Codes Yes National Flood Insurance Program Yes Community Rating System No Other (if any) Administrative & Technical Capability Planning Commission Yes Floodplain Administration No GIS Capabilities Yes Chief Building Official Yes Civil Engineering Yes Local Staff Who Can Assess Community’s Vulnerability to Hazards No Grant Manager No Mutual Aid Agreement Yes Other (if any) Fiscal Capability Capital Improvement Plan/ 1 & 6 Year Plan Yes Applied for grants in the past Yes Awarded a grant in the past Yes Authority to Levy Taxes for Specific Purposes such as Mitigation Projects Yes Gas/Electric Service Fees Yes Storm Water Service Fees Yes Water/Sewer Service Fees Yes Development Impact Fees Yes General Obligation Revenue or Special Tax Bonds Yes Other (if any) Education & Outreach Capability Local citizen groups or non-profit organizations focused on environmental protection, emergency preparedness, access and functional needs populations, etc. Ex.

Each plan is listed below along with a short description of how it is integrated with the hazard mitigation plan. The city will seek out and evaluate any opportunities to integrate the results of the current hazard mitigation plan into other planning mechanisms and updates. Grants and Funding The City of Adel’s funds are sufficient to pursue new capital projects. A large portion of municipal funds have been dedicated to two new projects, a well-water treatment plant and a wastewater treatment plant. The amount of municipal funds has increased in recent years due to population and commercial growth in the city. The municipal budget currently includes several hazard mitigation planning projects. These projects are alter/warning sirens, backup generators, and an updated stormwater system. The city applied for and was awarded the USDA/RD, WTFAP, and DOT Bridge Funding grants in the last five years. Building Code (2006) The building code sets standards for constructed buildings and structures. The city has adopted the 2006 International Building Codes with multiple amendments made. These codes regulate and govern the conditions and maintenance of all property, buildings, and structures by providing the standards for supplied utilities, facilities, and other physical things and conditions essential to ensure that structures are safe, sanitary, and fit for occupation and use. Comprehensive Plan (2020) The comprehensive plan is designed to guide the future actions and growth of the city. It incorporates some of the goals and objectives included in the HMP. The Comprehensive Plan discusses flood hazards and limits density in areas adjacent to known hazardous areas. It contains goals and objectives aimed at Safe Growth, encourages infill development, “clustering of development” in sensitive areas, and the preservation of open space in hazard prone areas. Currently there is no plan or timeline for the next update of the city’s Comprehensive Plan, but the next update will further incorporate the HMP by identifying areas in need of emergency shelters. ---PAGE BREAK--- Section Seven: City of Adel Community Profile Dallas County Hazard Mitigation Plan I 2023 11 Floodplain Regulations (2018), Floodplain Ordinance (2022), Zoning Ordinance (2013), and Subdivision Regulations (2015) The Zoning Ordinances are continually updated as needed and the corresponding Floodplain Ordinances is currently being updated. The Ordinances prohibit development within the floodplain and identify floodplain areas as parks of open space. They also limit population density in the floodplain and prohibit filling of wetlands. Furthermore, they limit development in the extraterritorial jurisdiction, include well setback requirements, and the ability to implement water restrictions. The ordinances do not require more than one foot of elevation above base flood elevation in the floodplain, discourage development along major transportation route, or consider wildfire and the wildland urban interface. The future ordinance updates will discourage development near chemical storage sites and future subdivision regulations will allow density transfers in hazard areas. Water System Emergency Response Plan (2021) Water system emergency response plans ensure the drinking water systems that serve the City of Adel are prepared to supply customers with drinking water in the event of an emergency. It includes identifying potential emergencies and how the utility will ensure water delivery in specific scenarios. Wellhead Protection Plan (2021) The purpose of wellhead protection plans is to protect the public drinking water supply wells from contamination. It includes identifying potential sources of groundwater contamination in the area. Future Development Trends In the last five years, many new developments have taken place in Adel. New buildings such as houses, businesses, a new Water Treatment Plant and a new Wastewater Treatment Plan have been built. Two new wells and a transmission main have been installed. The city has also built a new park and developed new streets. A new storage facility was also built, which is located within an inundation area near the North Raccoon River. In the next five years, the southern, eastern, and western portions of Adel are scheduled for new housing developments or new business or industry areas. Community Lifelines Transportation Adel’s major transportation corridors include U.S. Highway 169 and U.S. Highway 6, which meet on the east side of the city. The most traveled route is Highway 6 with an average of 8,400 vehicles daily, 564 of which are trucks.16 The Des Moines International Airport is located about 19 miles southeast of Adel. Local N. 15th Street is also a route of concern for the local planning team. Transportation information is important to hazard mitigation plans because it suggests possible evacuation corridors in the community, as well as areas more at risk of transportation incidents. The local planning team has indicated that it is unknown if there are any chemicals regularly transported along local routes and that the city has never experienced a chemical spill or other 16 Iowa Department of Transportation. 2020.

There are also no critical facilities located along the main transportation routes. Hazardous Materials There are gas transmission pipelines that travel near the city and can be seen as blue lines in the figure below. Figure ADL.4: Pipelines Source: National Pipeline Mapping System17 According to the Tier II System reports submitted to the Iowa Department of Natural Resources, there are 12 chemical storage sites in Adel that contain hazardous chemicals. In the event of a chemical spill, the local fire department and emergency response may be the first to respond to the incident.

The selected hazards were prioritized by the local planning team based on historical hazard occurrences, potential impacts, and the community’s capabilities. For additional discussion regarding area-wide hazards, please see Section Four: Risk Assessment. Flooding According to the NCEI, there were 20 flood events in Adel from 1996 to 2021. These events resulted in $9,923,070 in property damage, but no injuries or fatalities. The local planning team indicated that in July 1993, the Raccoon River flooded at 1.3 times the 100-year flood discharge level and damaged all of the land adjacent to the river. Other floods that occurred in 2008, 2010, and 2020 destroyed the road at Island Park, the ball fields at FK Park, and resulted in other property damage. Since then, the city has erected a berm system with HESCO Barriers for flood control. The planning team indicated that they plan to raise the bridge on Highway 169 to avoid future floods closing the road. 20 Federal Emergency Management Agency. 2022. “FEMA Flood Map Service Center.” Accessed December 2022. ---PAGE BREAK--- Section Seven: City of Adel Community Profile Dallas County Hazard Mitigation Plan I 2023 17 Residents from Adel responded to the public survey and reported that past impacts from this hazard include flooding at Kinnick Feller Park and Island Park, closing Highway 169, and damaging housing and roads, especially in the northern area of the city. Adel has six NFIP policies in-force for $857,800 as of June 2022. A FEMA Flood Insurance Study for Dallas County, including Adel, was revised in December 2018, and can be viewed on FEMA’s Flood Map Service Center: According to the IDNR, there are zero repetitive flood loss properties in Adel. Infrastructure Failure – Storm Sewer The local planning team identified this as a top hazard due to past occurrences of storm and sanitary sewers being inundated during any major rainstorm. The inundation of these sewers then leads to the flooding of local basements. The NCEI database records 14 instances of heavy rainfall having occurred in Adel, with 2015 and 2019 having experienced three and six heavy rainfall events respectively. The city has completed action to reduce their risk to the inundation of these sewers including upsizing and extending storm sewers with the 2017 street project and 2018 storm sewer project. Future planned actions such as new storm sewers and detention basins being installed in all new subdivisions will help increase the city’s resilience against this hazard. Severe Thunderstorms (Includes Hail and Lightning) Severe thunderstorms are a regular part of the climate and weather for Adel. These storms can cause damage through heavy rain, lightning strikes, hail, and high winds. The NCEI reports 49 instances of severe thunderstorms occurring in Adel from 1998 to 2019. The typical damage seen caused by these severe thunderstorms was toppled trees and power poles or wires due to high winds. These storms caused a total of $9,687,000 worth of damage across the impacted zones. Additionally, the local planning team reported that the 2020 derecho and 2022 spring storms resulted in power outages, downed trees, and road closures. The most significant concern identified by the local planning team was the loss of life due to severe thunderstorms. This could occur through fires started via lightning strikes, someone being caught by a falling tree, or electric shocks caused by downed power lines or poles. Backup power generators have been installed everywhere but City Hall and the city offers text alerts via phones for severe weather. To reduce the risk from this hazard, the city has installed outdoor warning sins, added generators at the wells of the water treatment plant and all sewage pumping streets of the sewage treatment plant, and strives to keep trees trimmed. Additionally, the local planning team has trimmed trees and added storm sirens to reduce the city’s risk to severe thunderstorms. Severe Winter Storms Severe winter storms are a regular part of the climate and weather for Adel. Severe winter storms include blizzards, ice accumulation, heavy snow, and winter storms. These storms can cause power outages during bitterly cold temperatures, road closures, and economic impacts. In March 1990 an ice storm hit Adel and resulted in downed power lines and tree branches and power outages across the city. According to the NCEI, there were 79 winter storm events in Dallas County from 1996 to 2021. One of these storm events in 2012 resulted in 7.8 inches of snowfall in Adel. These 79 events resulted in $6,613,680 in property damages, with no injuries or deaths reported. Additionally, the USDA Risk Management Agency reported almost $375,000 in crop damages from severe winter storm events from 2000 to 2021. ---PAGE BREAK--- Section Seven: City of Adel Community Profile 18 Dallas County Hazard Mitigation Plan I 2023 The most significant concern identified by the local planning team was the loss of life due to severe thunderstorms. This could occur through individuals being caught out in the storms or power outages resulting in the loss of heating in homes. Currently, no loss of life or injury has occurred in Adel due to a severe winter storm. To reduce the risk from this hazard, the city keeps trees trimmed, has installed outdoor warning sirens, and has added snow removal equipment to the city’s inventory. Roughly 25% of power lines within the city are buried, reducing the risk of power outage due to heavy snow and ice accumulation or downed trees. According to the local planning team, snow removal resources are sufficient to handle snow accumulation after a winter storm. Tornado and Windstorms The local planning team identified tornado and windstorm as a top hazard due to their prevalence in the area and potential for damage and loss of life. Windstorms are common across the county and can cause property and tree damage and brief power outages. Tornadoes are much less common, but the impacts can be far greater. Between 1996 and 2021, the NCEI recorded 31 high wind events in Dallas County and two tornadoes in Adel. The first tornado event occurred in May 2004 with an F1 tornado that tracked through open fields for the most part. This tornado resulted in $2,000 in property damage and $5,000 in crop damage. No deaths or injuries were reported. The second tornado event occurred in May 2013 with an EF0 tornado. No injuries or other damages were reported. The most significant concern identified by the local planning team was the loss of life. This could occur if someone is caught out in the storm and is hit by debris or if the building they are in sustained disastrous damage. To reduce the risk from this hazard, the city has installed outdoor warning sirens and added generators at the wells of the water treatment plant and all sewage pumping streets of the sewage treatment plant. In the future, to reduce risk to the community, the local planning team plans on installing storm sirens and ensure trees are kept trimmed and healthy. ---PAGE BREAK--- Section Seven: City of Adel Community Profile Dallas County Hazard Mitigation Plan I 2023 19 Mitigation Strategy Completed Mitigation and Strategic Actions Mitigation Action Alert/Warning Sirens Description Install additional outdoor warning siren locations within the annexation area.

Major waterways in the area include Beaver Creek and Little Beaver Creek. Demographics Bouton’s population in 2020 was 127. The following figure displays the historical population trend from 1920 to 2020. This figure indicates that the population of Bouton fluctuated from 1920 to 1990 but has since gradually decreased. A declining population can lead to more unoccupied housing that is not being maintained and is then at risk to high winds and other hazards. Furthermore, with fewer residents, there is decreasing tax revenue for the community, which can make implementation of mitigation projects fiscally challenging. Bouton’s population accounted for 0.1% of Dallas County’s population in 2020.21 Figure BOU.1: Population 1920 - 2020 Source: U.S. Census Bureau 21 United States Census Bureau. “2020 Census Redistricting Data (Public Law 94-171): P1: Race.” 187 141 162 159 145 160 139 149 136 129 127 0 20 40 60 80 100 120 140 160 180 200 Population Year ---PAGE BREAK--- Section Seven: City of Bouton Community Profile Dallas County Hazard Mitigation Plan I 2023 25 Figure BOU.2: City of Bouton ---PAGE BREAK--- Section Seven: City of Bouton Community Profile 26 Dallas County Hazard Mitigation Plan I 2023 The young, elderly, and minority populations may be more vulnerable to certain hazards than other groups. Looking at Bouton population: • 12.6% is non-white. Since 2010, Bouton became more ethnically diverse. In 2010, 1.6% of the Bouton population was non-white. By 2020, 12.6% was non-white.22 23 • 29.5 median age. The median age of Bouton was 29.5 years old in 2020.

Bouton’s population is younger with a higher percentage of the population below 40 years of age. This likely indicates a growing population in the years to come. 22 United States Census Bureau. “2020 Census Redistricting Data (Public Law 94-171): P1: Race.” 23 United States Census Bureau. “2010 Census Redistricting Data (Public Law 94-171): P1: Race.” 24 United States Census Bureau. “2020 Census Bureau American Community Survey: S0101: Age and Sex.” 25 United States Census Bureau. “2010 Census Bureau American Community Survey: S0101: Age and Sex.” 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Under 5 5 to 9 10 to 14 15 to 19 20 to 24 25 to 29 30 to 34 35 to 39 40 to 44 45 to 49 50 to 54 55 to 59 60 to 64 65 to 69 70 to 74 75 to 79 80 to 84 85 & Over Percentage of the Population Years Female % Male % ---PAGE BREAK--- Section Seven: City of Bouton Community Profile Dallas County Hazard Mitigation Plan I 2023 27 Employment and Economics Low-income populations, long distance commuters, and the unemployed may be more vulnerable to certain hazards than other groups. Bouton’s population has: • 17.6% of people living below the poverty line. The poverty rate (17.6%) in Bouton was greater than the state’s poverty rate (11.1%) in 2020. 26 • $48,750 median household income. Bouton’s median household income in 2020 ($48,750) was about $13,000 lower than the state ($61,836). 27 • 0% unemployment rate. In 2020 Bouton had a lower unemployment rate compared to the state (3.9%).28 • 57.6% of workers commuted 30 minutes or more to work. More workers in Bouton commuted 30 minutes or more to work than workers commuting less than 15 minutes (57.6% compared to 11.9%).29 According to the planning team, there are no major employers in the city. Most residents commute to other communities such as Perry and Des Moines for work. Housing The age of housing may indicate which housing units were built prior to the development of state building codes. Vacant housing stock may also be more vulnerable to hazard events if it is poorly maintained. Unoccupied housing may also suggest that future development may be less likely to occur. Communities with a substantial number of mobile homes may be more vulnerable to the impacts of high winds, tornadoes, and severe thunderstorms if those homes are not anchored correctly. Renter-occupied housing depends on the initiative of landlords for proper maintenance and retrofitting to be resilient to disasters. They are less likely than homeowners to have flood insurance, or to know their risks to flooding and other hazards. • 72.3% of housing built prior to 1970. Bouton has a greater share of housing built prior to 1970 than the state (72.3% compared to 50.4%).30 • 10.6% of housing units vacant. Since 2010, Bouton’s vacancy rate decreased. In 2010 the vacancy rate was 35.4%. By 2020, 10.6% of housing units were vacant. 31 32 • 12.8% mobile and manufactured housing. The City of Bouton had a larger share of mobile and manufactured housing (12.8%) compared to the state (3.6%).33 26 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 27 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 28 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 29 United States Census Bureau. “2020 Census Bureau American Community Survey: S0802: Means of Transportation to Work by Selected Characteristics.” 30 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 31 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 32 United States Census Bureau. “2010 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 33 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” ---PAGE BREAK--- Section Seven: City of Bouton Community Profile 28 Dallas County Hazard Mitigation Plan I 2023 • 14.3% renter-occupied.

Should any planning documents be prepared, hazard mitigation will be considered in their development, where applicable. City funds are limited to maintaining current facilities and municipal systems. The amount of municipal funds has increased in recent years. The city was awarded the Bock Family Grant and an I-CAP grant in the last five years. Future Development Trends In the last five years, there has been some new housing, a new street, and a new parking lot built. No new housing or business developments are currently planned for the next five years. Community Lifelines Transportation Bouton’s major transportation corridors include State Highway 141 and U.S. Highway 169. The most traveled route is Highway 141 with an average of 8,500 vehicles daily, 608 of which are trucks.36 Particular areas of concern include the school bus stop, the box culvert on the west side of town (128th Place), and the bridge on 130th Street, between Bouton and Woodward. According to the planning team, farming chemicals are regularly transported along the city’s two main roads. The nearest airport, Perry Municipal Airport, is located about eight miles southwest of Bouton. Transportation information is important to hazard mitigation plans because it suggests possible evacuation corridors in the community, as well as areas more at risk of transportation incidents.

The selected hazards were prioritized by the local planning team based on historical hazard occurrences, potential impacts, and the community’s capabilities. For additional discussion regarding area-wide hazards, please see Section Four: Risk Assessment. Flooding The local planning team identified flooding as a top hazard of concern for Bouton. According to the NCEI, there were four flood events in Bouton from 1996 to 2021. These events resulted in $150,000 in property damage, but no injuries or fatalities. The planning team indicated that flooding in 2019 was particularly impactful. Top concerns for this hazard include flooded roads and culvert/drainage systems. The city repaired the culvert on 4th Street to help with stormwater drainage. No projects are currently planned to reduce risk for flooding. As of June 2022, Bouton did not have NFIP policies in-force. A FEMA Flood Insurance Study for Dallas County, including Bouton, was revised in December 2018, and can be viewed on FEMA’s Flood Map Service Center: According to the IDNR, there are zero repetitive flood loss properties in Bouton. 40 Federal Emergency Management Agency. 2022. “FEMA Flood Map Service Center.” Accessed December 2022. ---PAGE BREAK--- Section Seven: City of Bouton Community Profile Dallas County Hazard Mitigation Plan I 2023 35 Severe Thunderstorms (Includes Hail and Lightning) Severe thunderstorms are common occurrences in Bouton. As such, the planning team identified it as a top concern. The NCEI recorded 11 severe thunderstorm events from 1996 to 2021, resulting in $94,000 in property damages. No injuries or fatalities were reported. The top concerns for this hazard include power outages, communication/alerts, and damage to trees and structures. According to the local planning team, multiple critical facilities have been damaged in the past from hail or severe thunderstorms including the Community Hall, Maintenance Building, Shelter House, and Park Restrooms. To reduce the impact of severe thunderstorms the Fire Department performs storm spotting and critical facilities are equipped with weather radios to provide advance warning of incoming storms. No projects are currently planned to reduce risk for flooding. Severe Winter Storms Severe winter storms are a regular part of the climate and weather for Bouton. Severe winter storms include blizzards, ice accumulation, heavy snow, and winter storms. These storms can cause power outages during bitterly cold temperatures, road closures, and economic impacts. According to the NCEI, there were 79 winter storm events in Dallas County from 1996 to 2021. These events resulted in $6,613,680 in property damages, with no injuries or deaths reported. Additionally, the USDA Risk Management Agency reported almost $375,000 in crop damages from severe winter storm events from 2000 to 2021. Top concerns identified by the local planning team include the efficiency of equipment and power outages. According to the local planning team, the city has not sustained damage to critical facilities due to severe winter storms in the past. To reduce the risk from this hazard, the city does use snow fences located at the empty lots west of 1st Street and the snow removal resources are sufficient to deal with snow accumulation after a storm. No projects are currently planned to reduce risk for severe winter storms. Tornado and Windstorm The local planning team identified tornado and windstorm as a top hazard due to their prevalence in the area and potential for damage and loss of life. Windstorms are common across the county and can cause property and tree damage and brief power outages. Tornadoes are much less common, but the impacts can be far greater. Between 1996 and 2021, the NCEI recorded 31 high wind events in Dallas County and one tornado in Bouton. The tornado event occurred in August 2014 with an EF0 tornado only damaging crops in its path. No injuries or other damages were reported. A derecho in August 2020 impacted the community and caused extensive damage Top concerns for this hazard include power outages, alerts/communication during an event, and damage to trees and structures. To minimize the effects of tornadoes and windstorms, the planning team indicated that the tornado siren needs to be updated, along with other city equipment. Backup generators are also needed. ---PAGE BREAK--- Section Seven: City of Bouton Community Profile 36 Dallas County Hazard Mitigation Plan I 2023 Mitigation Strategy New Mitigation and Strategic Actions Mitigation Action Storm Shelter/Restrooms Description Construct a community storm shelter/restroom on the new trail expansion Hazard(s) Tornado and Windstorms Estimated Cost $250,000 Funding City General Fund, HMA Timeline 2-5 years Priority Medium Lead Agency City Council Status Not started.

The city will seek out and evaluate any opportunities to integrate the results of the current hazard mitigation plan into other planning mechanisms and updates. Grants and Funding The City of Dallas Center’s funds are sufficient to pursue major projects and maintain facilities. For projects beyond those already planned, the city would acquire bonds to help pay for them. A large portion of municipal funds have been dedicated to the water system upgrades and sanitary sewer upgrade projects. The amount of municipal funds has increased in recent years. The city has funded a hazard mitigation plan to replace all three of our storm sirens, which is currently in progress. Over the last five years, the city has applied for several grants, receiving the FEMA storm siren grant, Trees Forever grant, Trees Please grant, Wellmark BCBS small matching grant, and the Dallas County Foundation Grant. Building Codes (2012) The building code sets standards for constructed buildings and structures. The city has adopted the 2012 International Building Codes with multiple amendments made. These codes regulate and govern the conditions and maintenance of all property, buildings, and structures by providing the standards for supplied utilities, facilities, and other physical things and conditions essential to ensure that structures are safe, sanitary, and fit for occupation and use. Capital Improvements Plan (2022) The capital improvement plan outlines large purchases and projects that the city would like to pursue. Projects identifies in the plan include stormwater projects, improving transportation routes for drainage, installing new municipal wells, and installing emergency generators in critical facilities. Additionally, the plan includes projects such as street improvement, sewer pipe lining, water distribution improvements, well field exploration, a new sanitary sewer lift station, and a swimming pool. The city plans to construct a new fire hall, a new public works/public safety facility, and improve the existing water treatment facility. Comprehensive Plan (2022) The comprehensive plan is designed to guide the future actions and growth of the city. The city’s plan contains growls aimed at Safe Growth. The plan does not encourage infill development or identifies areas that need emergency shelters. The plan was recently updated, and the city will not be updating it again for several years. ---PAGE BREAK--- Section Seven: City of Dallas Center Community Profile Dallas County Hazard Mitigation Plan I 2023 47 Floodplain Regulations (2022), Zoning Ordinance (2022), and Subdivision Regulations (2022) The city’s Zoning Ordinances are continually updates as needed. The city’s Floodplain Regulations contain floodplain maps but do not prohibit or discourage development within the floodplain. The city’s Zoning Ordinance does not regulate many aspects of development but does include a well setback requirement. Water System Emergency Response Plan (2008) Water system emergency response plans ensure the drinking water systems that serve the City of Dallas Center are prepared to supply customers with drinking water in the event of an emergency. It includes identifying potential emergencies and how the utility will ensure water delivery in specific scenarios. Future Development Trends In the past five years, the city has begun building four new housing developments – Lynn Crest Plats 2-5, Cross Country Estates Plat 6, The Neighborhood, and Skye View Estates. Major business changes include the expansion of Elite Electric, the addition of Dollar General, the removal of buildings and addition of a large new building by Hy-Line International, and the expansion of Midwest Oilseed’s employee base. In the next five years, the city plans for new housing developments to be built north, west, and east of town and a new business east of town. A future land use map for the city can be seen in the following figure. ---PAGE BREAK--- Section Seven: City of Dallas Center Community Profile Dallas County Hazard Mitigation Plan I 2023 48 Figure DCR.4: Future Land Use Map ---PAGE BREAK--- Section Seven: City of Dallas Center Community Profile Dallas County Hazard Mitigation Plan I 2023 49 Community Lifelines Transportation Dallas Center’s major transportation corridors include State Highway 44 and U.S. Highway 169, which intersect on the western edge of the city. The most traveled route is Highway 44 with an average of 5,700 vehicles daily, 568 of which are trucks.56 The city’s major water lines run along Highway 44 west of town and telecommunication lines are buried along most local routes. Heartland Cooperative transports ammonia from the center of town along these local routes. There have been no recent chemical spills or other significant transportation events locally. The nearest airport, Husband Field Airport, is located on the southwest edge of the city. Transportation information is important to hazard mitigation plans because it suggests possible evacuation corridors in the community, as well as areas more at risk of transportation incidents. Hazardous Materials A gas transmission pipeline travels near the city and can be seen as a blue line in the figure below.

The selected hazards were prioritized by the local planning team based on historical hazard occurrences, potential impacts, and the community’s capabilities. For additional discussion regarding area-wide hazards, please see Section Four: Risk Assessment. Animal and Plant Disease In 2014, 2015, and 2022, one of the city’s major employers, Hy-Line International, was threatened by the avian flu. Keeping the flocks free of avian flu incurred significant costs. Hy-Line’s valuable laying flocks provide the genetic basis for over 40% of the laying flocks throughout the world. If the avian flu had impacted their flock, the loss of birds could have had disastrous effects on Hy- Line and commercial egg production throughout the world. The local planning team identified their top concerns for this hazard as helping Hy-Line in keeping wild flocks of birds away from the Hy- Line layers and staff working with the chickens and providing the best bio-security measures possible to avoid spreading the avian flu. To help reduce the community’s risk to animal and plant disease, the city maintains and enforces a strict no backyard bird policy. According to the local planning team, it would help reduce risk to the community if the county passed a similar policy against small backyard flocks within a specific mileage of Hy-Line facilities to protect their critical infrastructure. 60 Federal Emergency Management Agency. 2022. “FEMA Flood Map Service Center.” Accessed December 2022. ---PAGE BREAK--- Section Seven: City of Dallas Center Community Profile 54 Dallas County Hazard Mitigation Plan I 2023 Residents from Dallas Center responded to the public survey and reported that past disease events also include trees being destroyed from the Emerald Ash Borer and Dutch Elm Disease. Hazardous Materials Release The city of Dallas Center has not experienced a known hazardous materials release within the past decade. However, a large distribution system for ammonia and other farm chemicals is maintained in the center of the city by Heartland Cooperative. Portable tanks move through the city on a regular basis and the large grain storage facilities are a known risk for explosions and fires. The local planning team has identified their top concerns for this hazard as a lack of knowledge regarding Heartland Cooperatives safety procedures and emergency response plans in the event a hazardous material is released through an accident or natural disaster. The city believes a future joint meeting with Dallas County and the Heartland Cooperative staff to discuss prevention and mitigation plans will reduce risk to the community. Infrastructure Failure The local planning team has identified infrastructure failure as a hazard of concern due to a history of inadequate storm water drainage within the city. During the major rainfall event of April 2018, when 5” or more of rain fell within a 24-hour period, the city experienced major basement flooding. The city’s water system was damaged in 2021 due to capacity reduction to handle dissolved minerals and particulates. The city’s top concern for infrastructure failure is the collection and removal of storm water. The soil beneath Dallas Center is made up of imperious clay that does not allow the water to seep into the earth. As the city grows, water system demands will rise and cause stress on the community water treatment system. To help reduce the risk of infrastructure failure, the city has completed Phase 1 of a major storm water system. The city believes flooding in the west portion of town will be greatly reduced during the next major rainfall. Additionally, the city had implemented significant upgrades to the city’s water treatment system and has reduced the water hardness and particulate load. In the future the city plans on completing Phase 2 of the storm water system when funding becomes available. Tornado and Windstorm The local planning team identified tornado and windstorm as a top hazard due to their prevalence in the area and potential for damage and loss of life. Windstorms are common across the county and can cause property and tree damage and brief power outages. Tornadoes are much less common, but the impacts can be far greater. Between 1996 and 2021, the NCEI recorded 31 high wind events in Dallas County and two tornadoes in Dallas Center. The two brief tornado events occurred in April 2004 and September 2019 with an F0 and EFU ratings respectively. No injuries or other damages were reported. Derechos in August 2020 and July 2022 impacted the community and caused significant tree damage and disrupted electrical services for several days. To minimize the effects of tornadoes and windstorms, the city has begun removing large trees that have been weakened by disease or age and removing tree limbs deemed a threat to overhead power lines. The city is looking at continuing with tree removal and trimmings, installing severe weather sirens, and performing a study to identify tornado shelter facilities within town. ---PAGE BREAK--- Section Seven: City of Dallas Center Community Profile Dallas County Hazard Mitigation Plan I 2023 55 Mitigation Strategy Completed Mitigation and Strategic Actions Mitigation Action Alert/Warning Sirens Description Purchase additional outdoor warning sirens Hazard(s) Tornado and Windstorms Estimated Cost $50,000 to $100,000 Funding City General Fund, HMA Timeline 2-3 years Priority High Lead Agency Fire Department Status Warning sirens have been purchased Mitigation Action Backup Generators Description Purchase three generators and the electric transfer gear for our water treatment plant.

The local planning team is responsible for reviewing and updating this profile as changes occur or after a major event. The planning team will include the City Administrator, the Public Works Director, and the City Clerk. The plan will be reviewed and updated bi-annually. The public will be involved in the review and revision process through the city website and other social media updates as well as reports to the City Council and all City Boards. ---PAGE BREAK--- Section Seven: City of Dallas Center Community Profile 58 Dallas County Hazard Mitigation Plan I 2023 This Page is Intentionally Blank ---PAGE BREAK--- Section Seven: City of Dawson Community Profile Dallas County Hazard Mitigation Plan I 2023 59 Community Profile City of Dawson Dallas County Hazard Mitigation Plan 2023 ---PAGE BREAK--- Section Seven: City of Dawson Community Profile 60 Dallas County Hazard Mitigation Plan I 2023 Local Planning Team Table DSN.1: Dawson Local Planning Team Name Title Jurisdiction Robin Wolfe City Clerk City of Dawson Clarence Morman Councilman City of Dawson Colton Morman Citizen/former Mayor City of Dawson Location and Geography The City of Dawson is located in northwest Dallas County and covers an area of 0.49 square miles. Major waterways in the area include the North Racoon River, which runs along the north side of the city. Demographics Dawson’s population in 2020 was 116. The following figure displays the historical population trend from 1910 to 2020. This figure indicates that the population of Dawson fluctuated from 1910 to 1940. Since then, the population has gradually decreased. A declining population can lead to more unoccupied housing that is not being maintained and is then at risk to high winds and other hazards. Furthermore, with fewer residents, there is decreasing tax revenue for the community, which can make implementation of mitigation projects fiscally challenging. Dawson’s population accounted for 0.1% of Dallas County’s population in 2020.61 Figure DSN.1: Population 1910 - 2020 Source: U.S. Census Bureau 61 United States Census Bureau. “2020 Census Redistricting Data (Public Law 94-171): P1: Race.” 275 300 262 289 286 257 232 229 174 155 131 116 0 50 100 150 200 250 300 350 Population Year ---PAGE BREAK--- Section Seven: City of Dawson Community Profile Dallas County Hazard Mitigation Plan I 2023 61 Figure DSN.2: City of Dawson ---PAGE BREAK--- Section Seven: City of Dawson Community Profile Dallas County Hazard Mitigation Plan I 2023 62 The young, elderly, and minority populations may be more vulnerable to certain hazards than other groups. Looking at Dawson’s population: • 11.2% is non-white. Since 2010, Dawson became more racially diverse. In 2010, 6.9% of the Dawson’s population was non-white. By 2020, 11.2% was non-white.62 63 • 30.4 median age. The median age of Dawson was 30.4 years old in 2020. The population became younger since 2010, when the median age was 37.7.64 65 Figure DSN.3: Population by Age Cohort and Sex (2020) Source: U.S. Census Bureau4 The figure above shows Dawson’s population percentage broken down by sex and five-year age groups. Dawson’s population is younger with a higher percentage of the population below 40 years of age. This likely indicates a growing population in the years to come. 62 United States Census Bureau. “2020 Census Redistricting Data (Public Law 94-171): P1: Race.” 63 United States Census Bureau. “2010 Census Redistricting Data (Public Law 94-171): P1: Race.” 64 United States Census Bureau. “2020 Census Bureau American Community Survey: S0101: Age and Sex.” 65 United States Census Bureau. “2010 Census Bureau American Community Survey: S0101: Age and Sex.” 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Under 5 5 to 9 10 to 14 15 to 19 20 to 24 25 to 29 30 to 34 35 to 39 40 to 44 45 to 49 50 to 54 55 to 59 60 to 64 65 to 69 70 to 74 75 to 79 80 to 84 85 & Over Percentage of the Population Years Female % Male % ---PAGE BREAK--- Section Seven: City of Dawson Community Profile Dallas County Hazard Mitigation Plan I 2023 63 Employment and Economics Low-income populations, long distance commuters, and the unemployed may be more vulnerable to certain hazards than other groups. Dawson’s population has: • 1.4% of people living below the poverty line. The poverty rate in Dawson was lower than the state’s poverty rate (11.1%) in 2020. 66 • $55,662 median household income. Dawson’s median household income in 2020 ($55,662) was about $6,200 lower than the state ($61,836). 67 • 0% unemployment rate. In 2020 Dawson had a lower unemployment rate compared to the state (3.9%).68 • 25.1% of workers commuted 30 minutes or more to work. Fewer workers in Dawson commuted 30 minutes or more to work than workers commuting less than 15 minutes (25.1% compared to 40.2%).69 Major Employers The city’s major employer is the Landus Cooperation. According to the local planning team, approximately 100% of residents commute to other communities for work, including Perry, Des Moines Metro, and Boone. Housing The age of housing may indicate which housing units were built prior to the development of state building codes. Vacant housing stock may also be more vulnerable to hazard events if it is poorly maintained. Unoccupied housing may also suggest that future development may be less likely to occur. Communities with a substantial number of mobile homes may be more vulnerable to the impacts of high winds, tornadoes, and severe thunderstorms if those homes are not anchored correctly. Renter-occupied housing depends on the initiative of landlords for proper maintenance and retrofitting to be resilient to disasters. They are less likely than homeowners to have flood insurance, or to know their risks to flooding and other hazards. • 94.8% of housing built prior to 1970. Dawson has a greater share of housing built prior to 1970 than the state (94.8% compared to 50.4%).70 • 30.2% of housing units vacant. Since 2010, Dawson’s vacancy rate decreased. In 2010 the vacancy rate was 10.7%. By 2020, 30.2% of housing units were vacant. 71 72 66 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 67 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 68 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 69 United States Census Bureau. “2020 Census Bureau American Community Survey: S0802: Means of Transportation to Work by Selected Characteristics.” 70 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 71 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 72 United States Census Bureau. “2010 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” ---PAGE BREAK--- Section Seven: City of Dawson Community Profile 64 Dallas County Hazard Mitigation Plan I 2023 • 3.1% mobile and manufactured housing. The City of Dawson had a smaller share of mobile and manufactured housing compared to the state (3.6%).73 • 14.9% renter-occupied. The rental rate of Dawson was 14.9% in 2020. The percentage increased since 2010, when renter occupied housing was at 10%.74 75 The city has four mobile homes located in different locations, but does not have a large mobile home park. Governance A community’s governance indicates the number of boards or offices that may be available to help implement hazard mitigation actions. Dawson has a mayor, a five-member city council, and the following offices. • Clerk/Treasurer • Water/Sewer Superintendent Capability Assessment The capability assessment consisted of a Capability Assessment Survey completed by the jurisdiction and a review of local existing policies, regulations, plans, and the programs.

Each plan is listed below along with a short description of how it is integrated with the hazard mitigation plan. The city will seek out and evaluate any opportunities to integrate the results of the current hazard mitigation plan into other planning mechanisms and updates. Funding and Grants The City of Dawson’s funds are sufficient to pursue new capital projects. The city has a large portion of municipal funds dedicated to improving transportation routes that run through town. The city’s municipal funds have increased over recent years. All projects identified in the hazard mitigation plan are included in the municipal budget. The county roads department applied for a grant to pay for the new roads being brought through town and was awarded it. Comprehensive Plan (2019) The comprehensive plan is designed to guide the future actions and growth of the city. The city recently updated their plan in 2019. Future Development Trends Over the past five years, the city has not performed many development projects. Four houses have been demolished and the city has allowed the lots to be transformed into green space. There are currently no housing, business, or industry plans in place for the next five years. Community Lifelines Transportation Dawson’s major transportation corridors include State Highway 141 and County Highway P46. The most traveled route is Highway 141 with an average of 3,220 vehicles daily, 443 of which are trucks.76 According to the local planning team, chemicals are regularly transported along local routes such as P46 traveling north and south and Railroad Ave. traveling east and west. These are typically farm chemicals being transported such as The Perry/Dawson fire station, an identified critical facility, is located along a main transportation route of on P46 and 1st Street. The P46 Dawson Water pump house is also located along a main transportation route north out of town. The nearest airport, Perry Municipal Airport, is located about 3 miles east of Dawson. Transportation information is important to hazard mitigation plans because it suggests possible evacuation corridors in the community, as well as areas more at risk of transportation incidents. 76 Iowa Department of Transportation. 2020.

The selected hazards were prioritized by the local planning team based on historical hazard occurrences, potential impacts, and the community’s capabilities. For additional discussion regarding area-wide hazards, please see Section Four: Risk Assessment. Severe Thunderstorms (includes Hail and Lightning) Severe thunderstorms are a regular part of the climate and weather for Dawson. These storms can cause damage through lightning strikes, hail, and high winds. The NCEI reports 22 instances of severe thunderstorms occurring in Dawson from 1998 to 2019. The typical damage seen caused by these severe thunderstorms was toppled trees and power poles due to high winds. These storms caused a total of $382,000 worth of structural damage. The most damaging storm occurred in 2008 and resulted in numerous trees uprooted and closing all but one road. Three house sustained tree damage, a few LP tanks leaked due to tree damage, and a grain elevator sustained damage in town. The top concern identified by the local planning team was the loss of power. To reduce risk and impacts to this hazard, the city has placed their powerlines underground. Severe Winter Storms Severe winter storms are a regular part of the climate and weather for Van Meter. Severe winter storms include blizzards, ice accumulation, heavy snow, and winter storms. These storms can cause power outages during bitterly cold temperatures, road closures, and economic impacts. According to the NCEI, there were 79 winter storm events in Dallas County from 1996 to 2021. These events resulted in $6,613,680 in property damages, with no injuries or deaths reported. Additionally, the USDA Risk Management Agency reported almost $375,000 in crop damages from severe winter storm events from 2000 to 2021. According to the local planning team a snowstorm in 2008 closed the town for multiple day. Downed trees covered roads and snow made road impassable. Significant concerns identified by the local planning team are the loss of power and water plants shutting down. The city has not experienced any structural damage to critical facilities from severe winter storms. To reduce risk and impacts to this hazard, the city has placed 99% of the powerlines underground of them having been buried and arranged for an emergency use generator. According to the local planning team, the city’s snow removal resources are sufficient. Tornado and Windstorm The local planning team identified tornado and windstorm as a top hazard due to their prevalence in the area and potential for damage and loss of life. Windstorms are common across the county and can cause property and tree damage and brief power outages. Tornadoes are much less common, but the impacts can be far greater. Between 1996 and 2021, the NCEI recorded 31 high wind events in Dallas County. No tornadoes have been reported in Dawson. According to the local planning team, derecho winds have impacted the city and resulted in damage to cars and buildings from downed trees. The top concern of the planning team is the loss of power and damage to the water tower or pumphouse. To minimize the effects of tornadoes and windstorms, the city has placed their powerlines underground. ---PAGE BREAK--- Section Seven: City of Dawson Community Profile 72 Dallas County Hazard Mitigation Plan I 2023 Mitigation Strategy New Mitigation and Strategic Actions Mitigation Action Backup Generator Description Provide a portable or stationary source of backup power to redundant power supplies, municipal wells, lift stations and other critical facilities and shelters.

Major waterways in the area include South Racoon River and Bulger Creek. Demographics De Soto’s population in 2020 was 915. The following figure displays the historical population trend from 1880 to 2020. This figure indicates that the population of De Soto remained relatively stable from 1880 to 1970, saw a dramatic increase from 1970-1980, and leveled off again from 1980 to 2010. Over the past decade, however, the number has decreased. A declining population can lead to more unoccupied housing that is not being maintained and is then at risk to high winds and other hazards. Furthermore, with fewer residents, there is decreasing tax revenue for the community, which can make implementation of mitigation projects fiscally challenging. De Soto’s population accounted for 0.9% of Dallas County’s population in 2020.80 Figure DSO.1: Population 1880 - 2020 Source: U.S. Census Bureau 80 United States Census Bureau. “2020 Census Redistricting Data (Public Law 94-171): P1: Race.” 347 328 345 356 261 319 274 280 273 369 1,035 1,033 1,009 1,050 915 0 200 400 600 800 1,000 1,200 Population Year ---PAGE BREAK--- Section Seven: City of De Soto Community Profile Dallas County Hazard Mitigation Plan I 2023 75 Figure DSO.2: City of De Soto ---PAGE BREAK--- Section Seven: City of De Soto Community Profile Dallas County Hazard Mitigation Plan I 2023 76 The young, elderly, and minority populations may be more vulnerable to certain hazards than other groups. Looking at De Soto’s population: • 8.6% is non-white. Since 2010, De Soto became more racially diverse. In 2010, 3.4% of the De Soto’s population was non-white. By 2020, 8.6% was non-white.81 82 • 35.1 median age. The median age of De Soto was 35.1 years old in 2020. The population became younger since 2010, when the median age was 35.8.83 84 Figure DSO.3: Population by Age Cohort and Sex (2020) Source: U.S. Census Bureau4 The figure above shows De Soto’s population percentage broken down by sex and five-year age groups. De Soto’s population is relatively stable with most of the population spread out between different age groups. This indicates that the population is likely to remain stable in the future. 81 United States Census Bureau. “2020 Census Redistricting Data (Public Law 94-171): P1: Race.” 82 United States Census Bureau. “2010 Census Redistricting Data (Public Law 94-171): P1: Race.” 83 United States Census Bureau. “2020 Census Bureau American Community Survey: S0101: Age and Sex.” 84 United States Census Bureau. “2010 Census Bureau American Community Survey: S0101: Age and Sex.” 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Under 5 5 to 9 10 to 14 15 to 19 20 to 24 25 to 29 30 to 34 35 to 39 40 to 44 45 to 49 50 to 54 55 to 59 60 to 64 65 to 69 70 to 74 75 to 79 80 to 84 85 & Over Percentage of the Population Years Female % Male % ---PAGE BREAK--- Section Seven: City of De Soto Community Profile Dallas County Hazard Mitigation Plan I 2023 77 Employment and Economics Low-income populations, long distance commuters, and the unemployed may be more vulnerable to certain hazards than other groups. De Soto’s population has: • 3.6% of people living below the poverty line. The poverty rate in De Soto was lower than the state’s poverty rate (11.1%) in 2020. 85 • $73,021 median household income. De Soto’s median household income in 2020 ($73,021) was about $11,200 higher than the state ($61,836). 86 • 3.7% unemployment rate. In 2020 De Soto had a lower unemployment rate compared to the state (3.9%).87 • 24.8% of workers commuted 30 minutes or more to work. Fewer workers in De Soto commuted 30 minutes or more to work than workers commuting less than 15 minutes (24.8% compared to 26.5%).88 Major Employers Major employers for the city include Dollar General, Casey’s, Kum and Go, Kwik Star, and All States Ag. According to the local planning team, a large percentage of residents commute to other communities for work such as West Des Moines and Des Moines. Housing The age of housing may indicate which housing units were built prior to the development of state building codes. Vacant housing stock may also be more vulnerable to hazard events if it is poorly maintained. Unoccupied housing may also suggest that future development may be less likely to occur. Communities with a substantial number of mobile homes may be more vulnerable to the impacts of high winds, tornadoes, and severe thunderstorms if those homes are not anchored correctly. Renter-occupied housing depends on the initiative of landlords for proper maintenance and retrofitting to be resilient to disasters. They are less likely than homeowners to have flood insurance, or to know their risks to flooding and other hazards. • 19.5% of housing built prior to 1970. De Soto has a smaller share of housing built prior to 1970 than the state (19.5% compared to 50.4%).89 • 9.6% of housing units vacant. Since 2010, De Soto’s vacancy rate increased. In 2010 the vacancy rate was 5.2%. By 2020, 9.6% of housing units were vacant. 90 91 85 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 86 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 87 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 88 United States Census Bureau. “2020 Census Bureau American Community Survey: S0802: Means of Transportation to Work by Selected Characteristics.” 89 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 90 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 91 United States Census Bureau. “2010 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” ---PAGE BREAK--- Section Seven: City of De Soto Community Profile 78 Dallas County Hazard Mitigation Plan I 2023 • 20.4% mobile and manufactured housing. The City of De Soto had a greater share of mobile and manufactured housing (20.4%) compared to the state (3.6%).92 • 16.7% renter-occupied. The rental rate of De Soto was 16.7% in 2020. The percentage increased since 2010, when renter occupied housing was at 14.5%.93 94 The city has approximately 60 trailer homes at the Holiday Terrace Mobile Home Park with the potential for up to 99 mobile homes to be located here. Governance A community’s governance indicates the number of boards or offices that may be available to help implement hazard mitigation actions. De Soto has a mayor, a five-member city council, and the following offices. • Clerk/Treasurer • Attorney • Chief of Police • Fire Chief • Wastewater Plant Superintendent • Water/Sewer Superintendent • Street Superintendent • City Inspector • Library Board Chairperson • GIS/Zoning Administrator • Public Transportation Director Capability Assessment The capability assessment consisted of a Capability Assessment Survey completed by the jurisdiction and a review of local existing policies, regulations, plans, and the programs. The survey is used to gather information regarding the jurisdiction’s planning and regulatory capability; administrative and technical capability; fiscal capability; and educational and outreach capability.

Each plan is listed below along with a short description of how it is integrated with the hazard mitigation plan. The city will seek out and evaluate any opportunities to integrate the results of the current hazard mitigation plan into other planning mechanisms and updates. Grants and Funding The City of De Soto’s funds are limited to covering maintenance of current facilities and municipal systems only. A large portion of funds had been allocated to the recently completed new water treatment facility and no new projects are on the horizon for the city. Municipal funds have increased with the passing of the Local Option Sale Tax as well as new commercial and residential development. In recent years, the city has applied for CDBG grants and was awarded two $500,000 CDBG grants. Comprehensive Plan The comprehensive plan is designed to guide the future actions and growth of the city. The city’s plan contains goals aimed at Safe Growth. The city updates the plan per City Council discussion when needed. Zoning Ordinance (2020), Floodplain Ordinance, Subdivision Regulation The Zoning Ordinances and Floodplain Ordinances are updated any time the State of Iowa makes legal changes or when the City Attorney recommends updates. The Floodplain Ordinances contains floodplain maps, prohibits development within the floodplain, and limits population density in the floodplain. They also identify floodplain areas as parks of open space. The Zoning Ordinances include well setback requirements and will include the ability to implement water restrictions in future updates. The Subdivision Regulations do not allow density transfers in hazard areas or restrict subdivision of land within or adjacent to the floodplain. Building Codes (2015) The building code sets standards for constructed buildings and structures. The city has adopted the 2015 International Building Codes and the current Iowa Statewide Urban Design and Specifications (SUDAS). These codes regulate and govern the conditions and maintenance of all property, buildings, and structures by providing the standards for supplied utilities, facilities, and other physical things and conditions essential to ensure that structures are safe, sanitary, and fit for occupation and use. Water System Emergency Response Plan (2021) Water system emergency response plans ensure the drinking water systems that serve the City of De Soto are prepared to supply customers with drinking water in the event of an emergency. It ---PAGE BREAK--- Section Seven: City of De Soto Community Profile Dallas County Hazard Mitigation Plan I 2023 81 includes identifying potential emergencies and how the utility will ensure water delivery in specific scenarios. Wellhead Protection Plan (2012) The purpose of wellhead protection plans is to protect the public drinking water supply wells from contamination. It includes identifying potential sources of groundwater contamination in the area. Future Development Trends Over the past five years, the city has had new residential housing built and a new Kwik Star business come to town. In the next five years, a new housing development is planned east of De Soto School, a new business is planned to be built either behind the Kum & Go or north of the interstate within the Industrial area. A future land use map for the city can be seen in the following figure. Community Lifelines Transportation De Soto’s major transportation corridors include U.S. Highway 169 and Interstate 80. Highway 169 has an average of 5,700 vehicles daily, 308 of which are trucks. Interstate 80 has an average of 23,800 vehicles daily, with 7,680 of those being trucks.95 As a rural area, farming chemicals are frequently transported through town, however a dairy tanker truck spilling into a water way by the Kum & Go has been the only recorded chemical spill to occur locally according to the local planning team. Other significant transportation incidents in town include tall loads having struck the I-80 bridge and impacting traffic flow on Highway 169. De Soto has one rail line, the Iowa Interstate Railroad, which travels along the southern edge of the community. The Des Moines International Airport is located about 18 miles east of De Soto. Transportation information is important to hazard mitigation plans because it suggests possible evacuation corridors in the community, as well as areas more at risk of transportation incidents. 95 Iowa Department of Transportation. 2020.

The selected hazards were prioritized by the local planning team based on historical hazard occurrences, potential impacts, and the community’s capabilities. For additional discussion regarding area-wide hazards, please see Section Four: Risk Assessment. Severe Thunderstorms (Includes Hail and Lightning) Severe thunderstorms are a regular part of the climate and weather for De Soto. These storms can cause damage through lightning strikes, hail, and high winds. The NCEI reports 11 instances of severe thunderstorms occurring in De Soto from 1998 to 2019. The typical damage seen caused by these severe thunderstorms was toppled trees and power poles or wires due to high winds. These storms caused a total of $192,000 worth of damage across Dallas County. Additionally, the local planning team reported on one event that were not included in the NCEI database. In 2008, a lightning strike hit the city’s water well pumps and the water treatment plant. The city was under a boil water order for three days while repairs were made. The local planning team’s main concern for this hazard was the damage sustained to infrastructure during storms. To reduce risk and impacts to this hazard, the city has equipped the new water treatment plant with a generator. Severe Winter Storms Severe winter storms are a regular part of the climate and weather for De Soto. Severe winter storms include blizzards, ice accumulation, heavy snow, and winter storms. These storms can cause power outages during bitterly cold temperatures, road closures, and economic impacts. According to the NCEI, there were 79 winter storm events in Dallas County from 1996 to 2021. These events resulted in $6,613,680 in property damages, with no injuries or deaths reported. Additionally, the USDA Risk Management Agency reported almost $375,000 in crop damages from severe winter storm events in the county from 2000 to 2021. The local planning team reports that there have been various past occurrences of major snowfall. The top concern identified by the local planning team was traffic control during a storm. The planning team indicated that a storm shelter/community building was needed in the future to reduce risk to the community. Snow removal resources were reported to be sufficient. Tornado and Windstorm The local planning team identified tornado and windstorm as a top hazard due to their prevalence in the area and potential for damage and loss of life. Windstorms are common across the county and can cause property and tree damage and brief power outages. Tornadoes are much less common, but the impacts can be far greater. Between 1996 and 2021, the NCEI recorded 31 high wind events in Dallas County and three tornados in De Soto. The first tornado event occurred in June 1998 with an F1 tornado with winds in excess of 100 MPH that did not cause excessive damage in De Soto. The second reported tornado was in April 1999 and was an F3 tornado with no injuries or deaths reported. The third tornado occurred March 2003 and was an F0 level tornado that briefly touched down in an open field with no damages. The local planning team’s top concern with windstorm and tornado events is potential powerline damage. To minimize the effects of these events, the city has removed several dead trees in powerline right of ways. ---PAGE BREAK--- Section Seven: City of De Soto Community Profile Dallas County Hazard Mitigation Plan I 2023 87 Mitigation Strategy Completed Mitigation and Strategic Actions Mitigation Action Backup Generator Description Purchase and install new standby generator for the water treatment plant.

Waterways in the area include Jim Creek and Long Branch. Demographics Dexter’s population in 2020 was 640. The following figure displays the historical population trend from 1880 to 2020. This figure indicates that the population of Dexter has generally fluctuated from 1880 to 2020. However, the city saw an increase in population over the past decade. Increasing populations are associated with increased hazard mitigation and emergency planning requirements for development. Increasing populations can also contribute to increasing tax revenues, allowing communities to pursue additional mitigation projects. Dexter population accounted for 0.6% of Dallas County’s population in 2020.99 Figure DEX.1: Population 1880 - 2020 Source: U.S. Census Bureau 99 United States Census Bureau. “2020 Census Redistricting Data (Public Law 94-171): P1: Race.” 704 607 795 767 790 748 760 643 670 652 678 628 689 611 640 0 100 200 300 400 500 600 700 800 900 Population Year ---PAGE BREAK--- Section Seven: City of Dexter Community Profile Dallas County Hazard Mitigation Plan I 2023 91 Figure DEX.2: City of Dexter ---PAGE BREAK--- Section Seven: City of Dexter Community Profile Dallas County Hazard Mitigation Plan I 2023 92 The young, elderly, and minority populations may be more vulnerable to certain hazards than other groups.

According to the local planning team, a large percentage of residents commute to other communities for work, such as Des Moines and West Des Moines. Housing The age of housing may indicate which housing units were built prior to the development of state building codes. Vacant housing stock may also be more vulnerable to hazard events if it is poorly maintained. Unoccupied housing may also suggest that future development may be less likely to occur. Communities with a substantial number of mobile homes may be more vulnerable to the impacts of high winds, tornadoes, and severe thunderstorms if those homes are not anchored correctly. Renter-occupied housing depends on the initiative of landlords for proper maintenance and retrofitting to be resilient to disasters. They are less likely than homeowners to have flood insurance, or to know their risks to flooding and other hazards. • 69.7% of housing built prior to 1970.

Each plan is listed below along with a short description of hot it is integrated with the hazard mitigation plan. The city will seek out and evaluate any opportunities to integrate the results of the current hazard mitigation plan into other planning mechanisms and updates. Funding and Grants The City of Dexter’s municipal funds are limited to maintaining current facilities and municipal systems. There are currently no large projects planned for within the city’s funds. Municipal funds have increased over recent years. In the last five years the city has applied for several grants, including ones for safety signs, weather sirens, and the DMACC Water Environmental Technology (WET) program. The city was awarded a DMACC WET grant. Building Codes The building code sets standards for constructed buildings and structures. These codes regulate and govern the conditions and maintenance of all property, buildings, and structures by providing the standards for supplied utilities, facilities, and other physical things and conditions essential to ensure that structures are safe, sanitary, and fit for occupation and use. Capital Improvement Plan The capital improvement plan outlines large purchases and projects that the city would like to pursue. Projects identified in the plan include improving transportation routes for drainage, installing water meters for residential structures, constructing a new fire hall, improving the existing water treatment facility, and improving other existing community owned structures. The city plans to update the plan in the coming years and hopes to include upsizing water distribution pipes, installing emergency generators in critical facilities, and constructing a new police headquarters in the future update. Zoning Ordinance and Subdivision Regulations The city currently has a Zoning Ordinance in place that includes well setback requirements and allows the city the ability to implement water restrictions. The ordinances do not discourage development along major transportation routes. The city’s subdivision regulations do not allow density transfers in hazard areas not do they restrict subdivision of land within or adjacent to the floodplain. Water System Emergency Response Plan Water system emergency response plans ensure the drinking water systems that serve the City of Dexter are prepared to supply customers with drinking water in the event of an emergency. It includes identifying potential emergencies and how the utility will ensure water delivery in specific scenarios. ---PAGE BREAK--- Section Seven: City of Dexter Community Profile Dallas County Hazard Mitigation Plan I 2023 97 Wellhead Protection Plan The purpose of wellhead protection plans is to protect the public drinking water supply wells from contamination. It includes identifying potential sources of groundwater contamination in the area. Future Development Trends In the last five years, there have been three houses demolished and two new houses built in the city. The city has resurfaced various roads as well. Currently there are no new housing developments or new businesses planned for the next five years. A future land use map for the city can be seen in the following figure Figure DEX.4: Future Land Use Map ---PAGE BREAK--- Section Seven: City of Dexter Community Profile 98 Dallas County Hazard Mitigation Plan I 2023 Community Lifelines Transportation Dexter’s major transportation corridors include County Highway P48 and County Highway F65. Interstate 80 also runs near the city. Highway P48 has an average of 320 vehicles. Highway F65 has a daily average of 2,580 vehicles.114 Dexter has one rail line, the Iowa Interstate Railroad, which travels through the community. Transportation information is important to hazard mitigation plans because it suggests possible evacuation corridors in the community, as well as areas more at risk of transportation incidents. This fire station is the only critical facility located along the city’s main transportation routes. Dexter has agricultural chemicals regularly transported along local routes with none of the chemicals spilling locally to date. If a multi-vehicle pileup occurs on the interstate, the detour route brings a high flow of vehicles through Dexter. Hazardous Materials There are gas transmission pipelines that travel near the city and can be seen as blue lines in the figure below.

The selected hazards were prioritized by the local planning team based on historical hazard occurrences, potential impacts, and the community’s capabilities. For additional discussion regarding area-wide hazards, please see Section Four: Risk Assessment. Animal and Plant Disease The destruction of the Emerald Ash Borer has heavily impacted the City of Dexter’s ash tree populations. The dead ash trees become hazardous as they weaken and fall. In 2021, the city had an ash tree fall over the highway. Before it could be removed, a car crashed into it at highway speeds. The local planning team’s top concern is more dead trees falling and causing injuries and fatalities, power outages, and more traffic incidents. To reduce the risk of these concern, the city has started removing infected Ash trees throughout the city. Infrastructure Failure The local planning team is concerned about infrastructure failure impacting the city water system, resulting in the loss of adequate water supply. The city has experienced past events of well or water plant failures that have caused the city to activate the emergency water supply. The emergency water supply is not intended for long term activation, which raises concerns of the local planning team. The city is currently updating the water system and water alarm system to reduce the risk of infrastructure failure. Severe Winter Storms Severe winter storms are a regular part of the climate and weather for Dexter. Severe winter storms include blizzards, ice accumulation, heavy snow, and winter storms. These storms can cause power outages during bitterly cold temperatures, road closures, and economic impacts. According to the NCEI, there were 79 winter storm events in Dallas County from 1996 to 2021. These events resulted in $6,613,680 in property damages, with no injuries or deaths reported. Additionally, the USDA Risk Management Agency reported almost $375,000 in crop damages from severe winter storm events from 2000 to 2021. The local planning team reports past occurrences of excess snowfall blocking emergency routes and ice storms causing power failure in the city. The top concern identified by the local planning team was the safety of residents’ lives during a storm. To reduce risk and impacts to this hazard, the city has hired additional part time public works employees for snow removal and uses snow fences on the east side of town along the northern sides of State Street and Davis Street and in the western portion of town along the west side of Marshall Street. The city has entered into mutual aid agreements for interstate incidents and approximately 40-50% of powerlines within the city are buried. For future reduction of risk, the local planning team would like to install backup generators, improve tree removal, and increase Fire and EMS staffing and training for traffic incidents. The city’s snow removal resources are reported as being sufficient. ---PAGE BREAK--- Section Seven: City of Dexter Community Profile Dallas County Hazard Mitigation Plan I 2023 103 Tornado and Windstorm The local planning team identified tornado and windstorm as a top hazard due to their prevalence in the area and potential for damage and loss of life. Windstorms are common across the county and can cause property and tree damage and brief power outages. Tornadoes are much less common, but the impacts can be far greater. Between 1996 and 2021, the NCEI recorded 31 high wind events in Dallas County and one tornado in Dexter. The brief tornado event occurred in May 2004 with an EF0 tornado only briefly touching down in open fields. No injuries or other damages were reported. Derechos in 2020 impacted the community and caused power outages, uprooted trees, and damaged structures. The local planning team’s top concerns for this hazard included infrastructure failure, power outages, mass destruction, and even the potential for fatalities. To minimize the effects of tornadoes and windstorms, the city has had members of the fire department attend storm spotter trainings for early alert activations. The city is looking to continuing the training and implement a strong back up power supply. Transportation Incident This hazard was identified as a top hazard due to the city’s proximity to Interstate 80 that partially runs along the southern border of the city. The city has experienced multiple past motor vehicle collisions resulting in injuries and fatalities. The top concerns noted by the local planning team are those of fatalities, injuries, hazardous material spills resulting in environmental impacts, and secondary incidents. In a major incident, loss of life, environmental damage, hazardous releases, or economic disruption could impact the city. To help reduce the risk of transportation incidents, the city is working to implement a four way stop at a main intersection to help reduce collisions. Speed limits in town are being reduced and the fire department has attended extraction trainings. In the future, the city plans to increase local EMS staffing as well. ---PAGE BREAK--- Section Seven: City of Dexter Community Profile 104 Dallas County Hazard Mitigation Plan I 2023 Mitigation Strategy Completed Mitigation and Strategic Actions Mitigation Action Safe Rooms/Storm Shelters Description Designate emergency safe buildings for residents in the event of a tornado, windstorm, or other hazard event.

Each plan is listed below along with a short description of how it is integrated with the hazard mitigation plan. The city will seek out and evaluate any opportunities to integrate the results of the current hazard mitigation plan into other planning mechanisms and updates. Grants and Funding The City of Granger’s funds are limited to maintaining current facilities and municipal systems. A large portion of municipal funds have been dedicated to three projects, Highway 17’s sewer and water extension, improvements to State Street, and Highway 17 turn lanes with Iowa DOT. The amount of municipal funds is increasing due to an increase in development within the city. The municipal budget does not currently include any hazard mitigation projects identified in the HMP. Over the last five years, the city has applied for and been awarded multiple grants. Some of the grants the city has been awarded include Wellmark Foundation Grant, Dallas County Foundation Grant, grants from the State of Iowa, and many others. Building Codes (2015) The building code sets standards for constructed buildings and structures. The city has adopted the 2015 International Building Codes with multiple amendments made. These codes regulate and govern the conditions and maintenance of all property, buildings, and structures by providing the standards for supplied utilities, facilities, and other physical things and conditions essential to ensure that structures are safe, sanitary, and fit for occupation and use. The city will be updating building codes in the end of 2022 and early 2023. Capital Improvement Plans (2019) The capital improvement plan outlines large purchases and projects that the city would like to pursue. Projects identified in the plan include regular maintenance for drainage structures, regular maintenance for the storm sewer system, and widening roadways that would improve evacuations if they were required. The city plans to upsize water distribution pipes, install water meters for residential structures, and install emergency generators in critical facilities. Construction of a new fire hall, new police headquarter, and other community owned structures are planned. The ---PAGE BREAK--- Section Seven: City of Granger Community Profile Dallas County Hazard Mitigation Plan I 2023 115 existing community center has planned improvements. The capital improvement plan also includes projects revolving around vehicles, personnel, sidewalks, trails, a new city hall, sanitary sewer linings, street repair and equipment repair, park renovations, and the addition of an aquatic center. This plan is updated every 5 years and the city will be updating it in late 2022/early 2023. The future update of the plan will include installing new municipal wells, constructing a new public works facility, a new community storm shelter, and improvements to the existing water treatment facility. Comprehensive Plan (2013) The comprehensive plan is designed to guide the future actions and growth of the city. It incorporates some of the goals and objectives included in the HMP and discusses the natural hazards of flooding, severe winter storms, and tornadoes. The comprehensive plan contains goals and objectives aimed at Safe Growth, limits density in areas adjacent to known hazardous areas, identifies areas that need emergency shelters, and encourages preservation of open space in hazard-prone areas. Zoning Ordinance (2017), Floodplain Ordinance (2009), and Subdivision Regulations (2013) The city’s Floodplain Ordinance prohibits development within the floodplain and requires more than one foot of elevation above Base Flood Elevation in the floodplain. The ordinance also prohibits filling of wetlands. The Zoning Ordinances and Subdivision Regulations do not discourage or limit development in areas near potentially hazardous locations. The Subdivision Regulations do not allow density transfers in hazard areas. Community Wildfire Protection Plan (2014) The City of Granger participated in the Saylorville Flood Plain Community Wildfire Protection Plan (CWPP), which was developed in 2014. The Saylorville floodplain is located along the Des Moines River. The purpose of the CWPP is to help effectively manage wildfires and increase collaboration and communication among organizations who manage fire. The CWPP discusses area-specific historical wildfire occurrences and impacts, identifies areas most at risk from wildfires, discusses protection capabilities, and identifies wildfire mitigation strategies. Future Development Trends In the last five years, there have been 198 new housing permits awarded, a new business called Absolute Group has been established in the city and Grandwood Schools opened their doors. The city began their Sidewalk Improvement Program while also improving the Trail Bub Plaza. A few new plats were added to the city as well, including Ironwood Estates Plat 3 and 4, and the Landing at Oxley Creek Plat 1, 2, and 3. Three new developments are planned to occur in the next five years including a Fairway Stores within the Oak Creek PUD, and a Flex Space and Perficut within Oak Creek Plat 4. A future land use map for the city can be seen in the following figure. ---PAGE BREAK--- Section Seven: City of Granger Community Profile 116 Dallas County Hazard Mitigation Plan I 2023 Community Lifelines Transportation Granger’s major transportation corridors include State Highway 141 and State Highway 17. The most traveled route is Highway 141 with an average of 9,900 vehicles daily, 656 of which are trucks.133 According to the planning team, no chemicals are regularly transported along the local routes and no chemical spills or other significant transportation events have occurred locally. The nearest airport, Ankeny Regional Airport, is located about 14 miles southeast of Granger. Transportation information is important to hazard mitigation plans because it suggests possible evacuation corridors in the community, as well as areas more at risk of transportation incidents.

The selected hazards were prioritized by the local planning team based on historical hazard occurrences, potential impacts, and the community’s capabilities. For additional discussion regarding area-wide hazards, please see Section Four: Risk Assessment. Infrastructure Failure The local planning team is concerned about infrastructure failure as it could result in the disruption to households and businesses and may result in events such as business closures, utility disruptions in water, gas, and electric, or in the most extreme cases, calls for evacuation of the city. While there have not been any past occurrences of infrastructure failure, the consequences could include economic losses, high clean-up costs, a reduction of communication, or even potentially hazardous impacts to the health of the city’s citizens and the environment. No actions or projects have been completed to reduce the city’s risk of infrastructure failure. The local planning team has identified future actions or projects that are needed to help reduce the risk of infrastructure failure to the community. These actions or projects start with documenting each risk in detail, including potential impacts to the community, and assessing the risk associated with 137 Federal Emergency Management Agency. 2022. “FEMA Flood Map Service Center.” Accessed December 2022. ---PAGE BREAK--- Section Seven: City of Granger Community Profile Dallas County Hazard Mitigation Plan I 2023 121 each hazard. These hazards must then be prioritized and mitigated against. An increase in the community’s awareness and education regarding these hazards is also desired. Severe Thunderstorms (Includes Hail and Lightning) Severe thunderstorms are a regular part of the climate and weather for Granger. These storms can cause damage through lightning strikes, hail, and high winds. The NCEI reports 10 instances of severe thunderstorms occurring in Granger from 1998 to 2019. The typical damage seen caused by these severe thunderstorms was toppled trees and power poles or wires due to high winds. These storms caused a total of $5,060,000 worth of damage across Dallas County. Additionally, the local planning team reported on two events that were not included in the NCEI database. In October 2018, two lightning strikes as the wastewater plan which led to needing replacing a new ethernet switch, an analog input module, a plc processor, a transducer, a new T2400 Wireless AC, an alarm dialer, a DO probe, and a sampler. The sonic wall also had to be troubleshot to ensure it suffered no damage. Secondly, a storm in August 2020 brought Derecho Hail to the city and caused roof damage. Significant concerns identified by the local planning team included the damage to homes, vehicles, and/or businesses by downed trees on roads, loss or interruption of utilities, power outages, fires due to lightning strikes, flash flooding, disrupted cellphone service and other communication methods, economic loss, and even death. To reduce risk and impacts to this hazard, the city has installed outdoor warning sirens and has implemented an emergency plan and purchased insurance for the city. In the future, to reduce risk to the community, the local planning team hopes to educate citizens in how to listen for sires, develop their own emergency plan, report any downed trees or power lines, and keep personal insurance for homes and vehicles. Purchasing backup power systems for the outdoor warning sirens and backup generators for the city are also actions identified as future projects to reduce risk to the community. Tornado and Windstorm The local planning team identified tornado and windstorm as a top hazard due to their prevalence in the area and potential for damage and loss of life. Windstorms are common across the county and can cause property and tree damage and brief power outages. Tornadoes are much less common, but the impacts can be far greater. Between 1996 and 2021, the NCEI recorded 31 high wind events in Dallas County and two tornados in Granger. The first tornado event occurred in June 1998 with an F2 tornado with winds in excess of 100 MPH. The track was intermittent, indicating either one tornado touching down occasionally, or one or more weak tornadoes rotating around the meso circulation. A duplex was flattened by the winds. Two injuries were reported. The second reported tornado was on May 30, 2000. This quick touchdown did not result in any damage, injuries, or deaths and was ranked as an F0. To minimize the effects of tornadoes and windstorms, the city has installed outdoor warning sirens and an emergency plan in place. The city also has insurance. The city is looking to install a second outdoor warning siren and installing a backup power system for the sirens. the local planning team hopes to educate citizens in how to listen for sires, develop their own emergency plan, report any downed trees or power lines, and keep personal insurance for homes and vehicles. The city also plans to incorporate a storm shelter with a new public safety building and increase the backup generators owned by the city. Transportation Incident This hazard was identified as a top hazard due to the city’s proximity to Highway 141 on the southern border of the city as well as Highway 17 bordering the eastern side. The city has ---PAGE BREAK--- Section Seven: City of Granger Community Profile 122 Dallas County Hazard Mitigation Plan I 2023 performed traffic studies to assess speeds on Highway 17. The main concerns noted by the local planning team is that any major transportation incident can shut down the main roadways in the community. In a major incident, loss of life, environmental damage, hazardous releases, or economic disruption could impact the city. The city is working with the Department of Transportation as they plan to put in turning lanes at the intersection of Highway 17 and State Street to help with congestion on the highway. Future traffic studies will be conducted to assess speed with future growth. Emphasis on an increase in traffic safety communication and education will also be focused on by the city.

These updates are encouraged to occur after every major disaster event, alongside community planning documents annual budgets and Capital Improvement Plans), during the fall before the HMA grant cycle begins, and/or prior to other funding opportunity cycles begin, including CDBG, Water Sustainability Fund, Revolving State Fund, or other identified funding mechanisms. The local planning team is responsible for reviewing and updating this community profile as changes occur or after a major event. The local planning team will include the City Administrator, the Police Chief/Director of Public Safety, the Fire Chief, and the Public Works Director. The plan was last updated on July 5, 2022, and will be reviewed annually. The public will be included in the review and revision process via city council meetings, public forums, city website updates, city newsletters, and social media. ---PAGE BREAK--- Section Seven: City of Linden Community Profile Dallas County Hazard Mitigation Plan I 2023 125 Community Profile City of Linden Dallas County Hazard Mitigation Plan 2023 ---PAGE BREAK--- Section Seven: City of Linden Community Profile 126 Dallas County Hazard Mitigation Plan I 2023 Local Planning Team Table LIN.1: Linden Local Planning Team Name Title Jurisdiction City Council N/A City of Linden Location and Geography The City of Linden is located in west central Dallas County and covers an area of 0.78 square miles. Major waterways in the area include Middle Racoon River and Mosquito Creek. Demographics Linden’s population in 2020 was 200. The following figure displays the historical population trend from 1900 to 2020. This figure indicates that the population of Linden has fluctuated since 1900 but has trended downward in population size. The population remained stable over the past decade. Communities with a growing population may be more prone to developing additional land and building new structures, while communities with declining populations may lack adequate funds to pursue mitigation projects. Net population growth may increase the number of people and properties vulnerable to hazards. Linden’s population accounted for 0.2% of Dallas County’s population in 2020.138 Figure LIN.1: Population 1900 - 2020 Source: U.S. Census Bureau 138 United States Census Bureau. “2020 Census Redistricting Data (Public Law 94-171): P1: Race.” 314 315 267 314 298 290 258 278 264 201 226 199 200 0 50 100 150 200 250 300 350 Population Year ---PAGE BREAK--- Section Seven: City of Linden Community Profile Dallas County Hazard Mitigation Plan I 2023 127 Figure LIN.2: City of Linden ---PAGE BREAK--- Section Seven: City of Linden Community Profile Dallas County Hazard Mitigation Plan I 2023 128 The young, elderly, and minority populations may be more vulnerable to certain hazards than other groups. Looking at Linden’s population: • 6.5% is non-white. Since 2010, Linden became more racially diverse. In 2010, 1% of the Linden’s population was non-white. By 2020, 6.5% was non-white.139 140 • 39 median age. The median age of Linden was 39 years old in 2020. The population became younger since 2010, when the median age was 44.3.141 142 Figure LIN.3: Population by Age Cohort and Sex (2020) Source: U.S. Census Bureau4 The figure above shows Linden’s population percentage broken down by sex and five-year age groups. Linden’s population is relatively stable with most of the population spread out between different age groups. This indicates that the population is likely to remain stable in the future. Employment and Economics Low-income populations, long distance commuters, and the unemployed may be more vulnerable to certain hazards than other groups. Linden’s population has: 139 United States Census Bureau. “2020 Census Redistricting Data (Public Law 94-171): P1: Race.” 140 United States Census Bureau. “2010 Census Redistricting Data (Public Law 94-171): P1: Race.” 141 United States Census Bureau. “2020 Census Bureau American Community Survey: S0101: Age and Sex.” 142 United States Census Bureau. “2010 Census Bureau American Community Survey: S0101: Age and Sex.” 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Under 5 5 to 9 10 to 14 15 to 19 20 to 24 25 to 29 30 to 34 35 to 39 40 to 44 45 to 49 50 to 54 55 to 59 60 to 64 65 to 69 70 to 74 75 to 79 80 to 84 85 & Over Percentage of the Population Years Female % Male % ---PAGE BREAK--- Section Seven: City of Linden Community Profile Dallas County Hazard Mitigation Plan I 2023 129 • 7.7% of people living below the poverty line. The poverty rate in Linden was lower than the state’s poverty rate (11.1%) in 2020. 143 • $76,667 median household income. Linden’s median household income in 2020 ($76,667) was about $14,800 higher than the state ($61,836). 144 • 9% unemployment rate. In 2020 Linden had a higher unemployment rate compared to the state (3.9%).145 • 62.7% of workers commuted 30 minutes or more to work. More workers in Linden commuted 30 minutes or more to work than workers commuting less than 15 minutes (62.7% compared to 2%).146 Major Employers Major employers for the city include the city Library, Maintenance Shop, and the City Clerk’s Office. A large percentage of residents commute to other communities for work. Housing The age of housing may indicate which housing units were built prior to the development of state building codes. Vacant housing stock may also be more vulnerable to hazard events if it is poorly maintained. Unoccupied housing may also suggest that future development may be less likely to occur. Communities with a substantial number of mobile homes may be more vulnerable to the impacts of high winds, tornadoes, and severe thunderstorms if those homes are not anchored correctly. Renter-occupied housing depends on the initiative of landlords for proper maintenance and retrofitting to be resilient to disasters. They are less likely than homeowners to have flood insurance, or to know their risks to flooding and other hazards. • 78.6% of housing built prior to 1970. Linden has a greater share of housing built prior to 1970 than the state (78.6% compared to 50.4%).147 • 5.4% of housing units vacant. Since 2010, Linden’s vacancy rate decreased.

Future Development Trends In the last five years, limited development has occurred within the city with the only new development being a new bar established in town. No new housing developments or businesses are planned for the next five years. Community Lifelines Transportation Linden’s major transportation corridors include County Highway F51 and County Highway P30. The most traveled route is Highway P30, with an average of 350 vehicles daily.153 An additional route of concern is 270th Street that is easily damaged. According to the planning team, no chemicals are regularly transported along the local routes and no chemical spills or other significant transportation events have occurred locally. The nearest airport, Guthrie Center Municipal Airport, is located about nine miles northwest of Linden. Transportation information is important to hazard mitigation plans because it suggests possible evacuation corridors in the community, as well as areas more at risk of transportation incidents.

Critical Facilities The local planning team identified critical facilities that are vital for disaster response, public shelter, and essential for returning the jurisdiction’s functions to normal during and after a disaster per the FEMA Community Lifelines guidance. Critical facilities were identified during the original planning process and updated by the local planning team as a part of this plan update. The following table and figure provide a summary of the critical facilities for the jurisdiction.

The selected hazards were prioritized by the local planning team based on historical hazard occurrences, potential impacts, and the community’s capabilities. For additional discussion regarding area-wide hazards, please see Section Four: Risk Assessment. Animal and Plant Disease The local planning team has identified plants and animal disease as a top concern due to an excessive number of cats and racoons located at a property recently acquired by the city. To reduce the number of these animals, traps were set in June 2022. According to the local planning team the top concerns is that other animals such as domestic pets could get bitten and hurt or catch a sickness and that mice and rates will tear into buildings and destroy wires or other important components. To reduce the risk of animal diseases the city has sold two city properties with expectations of the new owners cleaning them up. Future actions the city would like to take to reduce risk includes a Trap, Neuter, Release program for the feral cat population within the town. Severe Thunderstorms (Includes Hail and Lightning) Severe thunderstorms are a regular part of the climate and weather for Linden. These storms can cause damage through lightning strikes, hail, and high winds. The NCEI reports 4 instances of severe thunderstorms occurring in Linden from 1998 to 2021. The damages seen caused by these severe thunderstorms included fallen tree limbs and a semi-truck blown over into a ditch. These storms caused a total of $60,000 worth of damage across Dallas County. Significant concerns identified by the local planning team is the lack of funds within the community to completely repair damages. To reduce risk and impacts to this hazard, the city has removed four damaged trees within the city park. In the future, to reduce risk to the community, the local planning team hopes to continue with tree removal and promote the repair of structures instead of abandoning them. Severe Winter Storms Severe winter storms are a regular part of the climate and weather for Linden. Severe winter storms include blizzards, ice accumulation, heavy snow, and winter storms. These storms can cause power outages during bitterly cold temperatures, road closures, and economic impacts. According to the NCEI, there were 79 winter storm events in Dallas County from 1996 to 2021. These events resulted in $6,613,680 in property damages, with no injuries or deaths reported. Additionally, the USDA Risk Management Agency reported almost $375,000 in crop damages from severe winter storm events from 2000 to 2021. The local planning team reports past occurrences of excess snowfall resulted in downed tree limbs and power lines due to excessive weight of the snow. The top concern identified by the local planning team was the possibility of falling branches, impassible roads, and ice falls. To reduce risk and impacts to this hazard, the city has spoken to the maintenance department regarding areas of concern along road where ice is frequently found. The city plans to continue with tree removal to reduce falling branches and ensure roads are salted or sanded. ---PAGE BREAK--- Section Seven: City of Linden Community Profile Dallas County Hazard Mitigation Plan I 2023 137 Tornado and Windstorm The local planning team identified tornado and windstorm as a top hazard due to their prevalence in the area and potential for damage and loss of life. Windstorms are common across the county and can cause property and tree damage and brief power outages. Tornadoes are much less common, but the impacts can be far greater. Between 1996 and 2021, the NCEI recorded 31 high wind events in Dallas County and no tornadoes in Linden. Additionally, the local planning team reported the August 2020 and December 2021 derechos damaged trees, houses, and fences within the community. Shingles were blown off houses and trees fell in yards and roads. Significant concerns identified by the local planning team is the lack of funds within the community to completely repair damages. To reduce risk and impacts to this hazard, the city has removed four damaged trees within the city park. In the future, to reduce risk to the community, the local planning team hopes to continue with tree removal. Mitigation Strategy Continued Mitigation and Strategic Actions Mitigation Action Construct New City Hall/Fire Station/Library as a Community Saferoom Description Construct a facility to provide shelter to citizens and city/fire department and library staff in the event of a tornado.

Plan Maintenance Hazard Mitigation Plans should be living documents and updated regularly to reflect changes in hazard events, priorities, and mitigation actions. These updates are encouraged to occur after every major disaster event, alongside community planning documents annual budgets and Capital Improvement Plans), during the fall before the HMA grant cycle begins, and/or prior to other funding opportunity cycles begin, including CDBG, Water Sustainability Fund, Revolving State Fund, or other identified funding mechanisms. The local planning team is responsible for reviewing and updating this profile as changes occur or after a major event. The planning team will include the City Council, Mayor, and Maintenance. The plan will be reviewed and updated annually. The public will be involved in the review and revision process through the City Council meetings. ---PAGE BREAK--- Section Seven: City of Linden Community Profile 138 Dallas County Hazard Mitigation Plan I 2023 This Page is Intentionally Blank ---PAGE BREAK--- Section Seven: City of Minburn Community Profile Dallas County Hazard Mitigation Plan I 2023 139 Community Profile City of Minburn Dallas County Hazard Mitigation Plan 2023 ---PAGE BREAK--- Section Seven: City of Minburn Community Profile 140 Dallas County Hazard Mitigation Plan I 2023 Local Planning Team Table MIN.1: Minburn Local Planning Team Name Title Jurisdiction Joe Stuetelberg Mayor City of Minburn Dan Case Fire Chief City of Minburn Megan Cline City Council City of Minburn Location and Geography The City of Minburn is located in north central Dallas County and covers an area of 0.26 square miles. Waterways in the area include Racoon River and Slough Creek. Demographics Minburn’s population in 2020 was 325. The following figure displays the historical population trend from 1900 to 2020. This figure indicates that the population of Minburn fluctuated from 1900 to 1930, gradually increased from 1930 to 1980, fluctuated again from 1980 to 2000, and has since seen a decline. A declining population can lead to more unoccupied housing that is not being maintained and is then at risk to high winds and other hazards. Furthermore, with fewer residents, there is decreasing tax revenue for the community, which can make implementation of mitigation projects fiscally challenging. Minburn’s population accounted for 0.3% of Dallas County’s population in 2020.156 Figure MIN.1: Population 1900 - 2020 Source: U.S. Census Bureau 156 United States Census Bureau. “2020 Census Redistricting Data (Public Law 94-171): P1: Race.” 317 388 418 328 335 353 357 378 390 346 391 365 325 0 50 100 150 200 250 300 350 400 450 Population Year ---PAGE BREAK--- Section Seven: City of Minburn Community Profile Dallas County Hazard Mitigation Plan I 2023 141 Figure MIN.2: City of Minburn ---PAGE BREAK--- Section Seven: City of Minburn Community Profile Dallas County Hazard Mitigation Plan I 2023 142 The young, elderly, and minority populations may be more vulnerable to certain hazards than other groups. Looking at Minburn’s population: • 3.1% is non-white. Since 2010, Minburn became more racially diverse. In 2010, 1.9% of the Minburn’s population was non-white. By 2020, 3.1% was non-white.157 158 • 33 median age. The median age of Minburn was 33 years old in 2020.

This likely indicates a growing population in the years to come. 157 United States Census Bureau. “2020 Census Redistricting Data (Public Law 94-171): P1: Race.” 158 United States Census Bureau. “2010 Census Redistricting Data (Public Law 94-171): P1: Race.” 159 United States Census Bureau. “2020 Census Bureau American Community Survey: S0101: Age and Sex.” 160 United States Census Bureau. “2010 Census Bureau American Community Survey: S0101: Age and Sex.” 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Under 5 5 to 9 10 to 14 15 to 19 20 to 24 25 to 29 30 to 34 35 to 39 40 to 44 45 to 49 50 to 54 55 to 59 60 to 64 65 to 69 70 to 74 75 to 79 80 to 84 85 & Over Percentage of the Population Years Female % Male % ---PAGE BREAK--- Section Seven: City of Minburn Community Profile Dallas County Hazard Mitigation Plan I 2023 143 Employment and Economics Low-income populations, long distance commuters, and the unemployed may be more vulnerable to certain hazards than other groups. Minburn’s population has: • 8 % of people living below the poverty line. The poverty rate in Minburn was lower than the state’s poverty rate (11.1%) in 2020. 161 • $59,000 median household income. Minburn’s median household income in 2020 ($59,000) was about $2,800 lower than the state ($61,836). 162 • 1% unemployment rate. In 2020 Minburn had a lower unemployment rate compared to the state (3.9%).163 • 52.8% of workers commuted 30 minutes or more to work. More workers in Minburn commuted 30 minutes or more to work than workers commuting less than 15 minutes (52.8% compared to 27.3%).164 Major Employers Major employers for the city include Heartland Cooperative, Minburn Communications, Ron Allen Trucking, Veterinary Medical Associates, Minburn Veterinary Clinic, Michelson Trucking, Casa Oaxaca, Hy-Line International, Stine Seed Company, and the City of Minburn. According to the local planning team, a large percentage of the residents commute to other communities for work, such as Des Moines Metro Area, Perry, Dallas Center, and Adel. Housing The age of housing may indicate which housing units were built prior to the development of state building codes. Vacant housing stock may also be more vulnerable to hazard events if it is poorly maintained. Unoccupied housing may also suggest that future development may be less likely to occur. Communities with a substantial number of mobile homes may be more vulnerable to the impacts of high winds, tornadoes, and severe thunderstorms if those homes are not anchored correctly. Renter-occupied housing depends on the initiative of landlords for proper maintenance and retrofitting to be resilient to disasters. They are less likely than homeowners to have flood insurance, or to know their risks to flooding and other hazards. • 75.7% of housing built prior to 1970. Minburn has a greater share of housing built prior to 1970 than the state (75.7% compared to 50.4%).165 • 16.5% of housing units vacant. Since 2010, Minburn’s vacancy rate increased. In 2010 the vacancy rate was By 2020, 16.5% of housing units were vacant. 166 167 161 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 162 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 163 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 164 United States Census Bureau. “2020 Census Bureau American Community Survey: S0802: Means of Transportation to Work by Selected Characteristics.” 165 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 166 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 167 United States Census Bureau. “2010 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” ---PAGE BREAK--- Section Seven: City of Minburn Community Profile 144 Dallas County Hazard Mitigation Plan I 2023 • 4.1% mobile and manufactured housing. The City of Minburn had a greater share of mobile and manufactured housing compared to the state (3.6%).168 • 23.5% renter-occupied. The rental rate of Minburn was 23.5% in 2020. The percentage increased since 2010, when renter occupied housing was at 18.6%.169 170 The city has between two and three mobile homes spread throughout the community, however there are no mobile home parks. Governance A community’s governance indicates the number of boards or offices that may be available to help implement hazard mitigation actions. Minburn has a mayor, a five-member city council, and the following offices. • Clerk/Treasurer • Attorney • Fire Chief • Library Board Chairperson • Public Works Director (water/sewer/streets) • Betterment Committee Capability Assessment The capability assessment consisted of a Capability Assessment Survey completed by the jurisdiction and a review of local existing policies, regulations, plans, and the programs. The survey is used to gather information regarding the jurisdiction’s planning and regulatory capability; administrative and technical capability; fiscal capability; and educational and outreach capability. 168 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 169 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 170 United States Census Bureau. “2010 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” ---PAGE BREAK--- Section Seven: City of Minburn Community Profile Dallas County Hazard Mitigation Plan I 2023 145 Table MIN.2: Capability Assessment Survey Components/Subcomponents Yes/No Planning & Regulatory Capability Comprehensive Plan No Capital Improvements Plan No Economic Development Plan No Emergency Operations Plan Yes Floodplain Management Plan No Storm Water Management Plan No Zoning Ordinance No Subdivision Regulation/Ordinance Yes Floodplain Ordinance No Building Codes No National Flood Insurance Program No Community Rating System No Other (if any) Administrative & Technical Capability Planning Commission No Floodplain Administration No GIS Capabilities No Chief Building Official No Civil Engineering No Local Staff Who Can Assess Community’s Vulnerability to Hazards Yes Grant Manager No Mutual Aid Agreement Yes Other (if any) Fiscal Capability Capital Improvement Plan/ 1 & 6 Year Plan No Applied for grants in the past Yes Awarded a grant in the past Yes Authority to Levy Taxes for Specific Purposes such as Mitigation Projects Yes Gas/Electric Service Fees Yes Storm Water Service Fees Yes Water/Sewer Service Fees Yes Development Impact Fees No General Obligation Revenue or Special Tax Bonds Yes Other (if any) Education & Outreach Capability Local citizen groups or non-profit organizations focused on environmental protection, emergency preparedness, access and functional needs populations, etc. Ex.

Each applicable planning mechanism is listed below along with a short description of how it is integrated with the hazard mitigation plan. The city will seek out and evaluate any opportunities to integrate the results of the current hazard mitigation plan into other planning mechanisms and updates. Funding and Grants The municipal funds for the City of Minburn are limited to maintaining existing facilities and systems. A large portion of the city’s municipal funds are dedicated to servicing debt on depot relocation and renovation. Funds are also dedicated to sanitary sewer system construction. Municipal funds have decreased in recent years. The city has applied for multiple grants including the Dallas County Foundation, Bock Foundation, and FEMA Assistance to Firefighters Grant. Of these grants, the city was awarded the Dallas County Foundation and the Bock Foundation Grants which funded improvement projects involving the Fire Department, City Hall, Betterment Club, and Library. Emergency Operations Plan (2022) Emergency Operations Plans are designed to provide procedures for the city to ensure residents and workers are safe during an emergency event. The plan details who the city will do during a disaster including incident command implementation, command center location and activities, and any specific actions city departments need to take to ensure safety of employees and city residents. ---PAGE BREAK--- Section Seven: City of Minburn Community Profile Dallas County Hazard Mitigation Plan I 2023 147 Future Development Trends In the last five years, there have been many new developments in the city. As a result of the Raccoon Valley Trail, new businesses including restaurants and an Airbnb have moved to town. The largest apartment complex in town underwent significant interior/exterior renovations and will be reopened to renters. The Dallas County Freedom Rock was constructed south of the depot and the land in the area has been improved for visitors. The Adel-DeSoto-Minburn school district leased a portion of the former elementary school building to the City of Minburn and the public library relocated to the school complex, allowing for an increase in their collection and programming. Housing turnover resulted in rehabilitation and improvements to the current housing stock throughout the community and new housing construction in the rural areas of the city. City parks have undergone improvements and upgrades. As of 2022, the café south of the downtown business district is being renovated and a new three- plex business incubator complex is under construction on Highway 169 immediately north of the Heartland Cooperative fuel station. These business locations will be available for leasing. Community Lifelines Transportation Minburn’s major transportation corridors include U.S. Highway 169 and County Highway F31. The most traveled route is Highway 169 with an average of 2,290 vehicles daily, 304 of which are trucks.171 The city Public Works shop, an identified critical facility, is located along Highway F-31 west of town. According to the local planning team, agricultural chemicals such as fertilizers, pesticides, and fuels are regularly transported along local routes. Minor fuel spills have occurred at the Heartland Cooperative and the Fire Department has responded to chemical spills outside of city limits. The 2020 derecho winds cause Highway 169 to be blocked by power lines and trees, causing the highway to be shut down and detours run through town. Minor flooding is a concern of the local planning team but has historically occurred outside city limits. The nearest airport, Perry Municipal Airport, is located about eight miles northwest of Minburn. The Racoon River Valley Trail intersects the town from Southeast to Northwest. The trail brings thousands of cyclists and other users such as snowmobilers and pedestrians through the community each year. The Fire Department’s Rescue unit has responded to several emergency incidents along the trail. Transportation information is important to hazard mitigation plans because it suggests possible evacuation corridors in the community, as well as areas more at risk of transportation incidents. 171 Iowa Department of Transportation. 2020.

The selected hazards were prioritized by the local planning team based on historical hazard occurrences, potential impacts, and the community’s capabilities. For additional discussion regarding area-wide hazards, please see Section Four: Risk Assessment. Hazardous Materials Release The city has experienced minor releases of ammonia at the Heartland Cooperative’s facility north of town. These occur when nurse tanks are not properly shut off or vented when threshold temperatures are reached. The top concern of the local planning team is the storage of significant volumes of chemicals and fuels within their facilities both in town and at Minburn Acres. Concerns are associated with the impact of any potential release or a fire at the facility. To help reduce these risks, the Minburn Fire Department conducts walk throughs of the facility every other year and discusses emergency planning with the cooperative. Additional pre-planning for incident management and running mock drills or exercises with the fire department and other responding agencies are future actions the city can take to reduce risk to the community. 174 Federal Emergency Management Agency. 2022. “FEMA Flood Map Service Center.” Accessed December 2022. ---PAGE BREAK--- Section Seven: City of Minburn Community Profile 152 Dallas County Hazard Mitigation Plan I 2023 Infrastructure Failure The city’s water distribution system has suffered several broken mains requiring repairs throughout the past five years. The city has issued boil water orders that resulted in the local population having difficulty procuring safe drinking water without boiling water or purchasing bottled water. Due to the fragility of the infrastructure and low flow rates, the fire department is unable to use the water distribution system for fire protection services. In the event of a structure fire within the community, water must be trucked into town via tankers. The lack of fire protection and potential health hazards resulting from a lack of clean, safe drinking water during system breakages is a top concern of the local planning team. In 2021 the water tower standpipe required significant repairs and was fully renovated in 2022. The city has met with an engineering firm to develop a long-range plan for upgrades to the water distribution system. In the future, the city hopes to upgrade or replace the entire water system with projects such as increasing the main connecting the community to the Xenia network, increasing the water main capacity and upgrading hydrants, adding loops to improve flow and mitigate leaks, and possibly replacing the city water tower. Severe Winter Storms Severe winter storms are a regular part of the climate and weather for Minburn. Severe winter storms include blizzards, ice accumulation, heavy snow, and winter storms. These storms can cause power outages during bitterly cold temperatures, road closures, and economic impacts. According to the NCEI, there were 79 winter storm events in Dallas County from 1996 to 2021. These events resulted in $6,613,680 in property damages, with no injuries or deaths reported. Additionally, the USDA Risk Management Agency reported almost $375,000 in crop damages from severe winter storm events from 2000 to 2021. Significant concerns identified by the local planning team are pro-longed power outages that impact residents through loss of heat, food, or other needs. Another concern is that some smaller facilities in town have generators for power, but locations that are designated as potential mass- care shelters do not have generators. To reduce risk to the community, the city has identified potential shelter locations. Securing a location with a permanent generator or a portable generator that can heat a warming center is a potential project for the future to reduce risk. Tornado and Windstorm The local planning team identified tornado and windstorm as a top hazard due to their prevalence in the area and potential for damage and loss of life. Windstorms are common across the county and can cause property and tree damage and brief power outages. Tornadoes are much less common, but the impacts can be far greater. Between 1996 and 2021, the NCEI recorded 31 high wind events in Dallas County and four tornados in Minburn. The first occurred in 2000 with a brief F0 tornado touching down in open country, resulting in no reported damage. In 2005, a tornado event with a total of eleven tornado resulted in a total of $2,500,000 of damage, one tornado touched down one mile west of Minburn and produced F0-F1 damage. In 2014 an EF0 tornado touched down in rural area and resulted in minimal damage. The final tornado occurred in 2019 and was rated an EFU. This tornado did not produce any damage and remained in open cropland east and northeast of Minburn. The planning team’s top concerns include sufficient warning and notification and the potential impacts to homes and business owners and infrastructure. According to the local planning team, the community has felt notable impact from the 2020 derecho which resulted in significant damage to structures, trees, and electrical infrastructure. The Heartland Cooperative complex north of town required the reconstruction of several grain bins that were destroyed by the derecho. Several homes required repair and tree debris removal was required. ---PAGE BREAK--- Section Seven: City of Minburn Community Profile Dallas County Hazard Mitigation Plan I 2023 153 To minimize the effects of tornadoes and windstorms, the city’s emergency operations plan was updated to improve the city’s response to this hazard. The city has promoted Dallas County’s RAVE alerting system to residents to ensure adequate warning times are received. Two storm sirens have been installed in the city, with one still functioning. Upgrading the city’s outdoor warning sirens will help reduce risk to the community.

Plan Maintenance Hazard Mitigation Plans should be living documents and updated regularly to reflect changes in hazard events, priorities, and mitigation actions. These updates are encouraged to occur after every major disaster event, alongside community planning documents annual budgets and Capital Improvement Plans), during the fall before the HMA grant cycle begins, and/or prior to other funding opportunity cycles begin, including CDBG, Water Sustainability Fund, Revolving State Fund, or other identified funding mechanisms. The local planning team is responsible for reviewing and updating this community profile as changes occur or after a major event. The local planning team will include the Mayor, the City Clerk, and the Fire Chief. The plan will be reviewed annually. The public will be included in the review and revision process via city newsletters, social media, and city council meetings. ---PAGE BREAK--- Section Seven: City of Minburn Community Profile 156 Dallas County Hazard Mitigation Plan I 2023 This Page is Intentionally Blank ---PAGE BREAK--- Section Seven: City of Perry Community Profile Dallas County Hazard Mitigation Plan I 2023 157 Community Profile City of Perry Dallas County Hazard Mitigation Plan 2023 ---PAGE BREAK--- Section Seven: City of Perry Community Profile 158 Dallas County Hazard Mitigation Plan I 2023 Local Planning Team Table PER.1: Perry Local Planning Team Name Title Jurisdiction Eric Vaughn Police Chief Perry Police Department Josh Wuebker Public Works Director City of Perry Sven Peterson City Administrator City of Perry John Andorf Mayor City of Perry Jack Butler Public Works Director (previous) City of Perry Location and Geography The City of Perry is located in north central Dallas County and covers an area of 5.49 square miles. Major waterways in the area include North Racoon River and Beaver Creek.. Demographics Perry’s population in 2020 was 7,836. The following figure displays the historical population trend from 1880 to 2020. This figure indicates that the population of Perry has generally increased from since 1880. Increasing populations are associated with increased hazard mitigation and emergency planning requirements for development. Increasing populations can also contribute to increasing tax revenues, allowing communities to pursue additional mitigation projects. Perry’s population accounted for 7.9% of Dallas County’s population in 2020.175 Figure PER.1: Population 1880 - 2020 Source: U.S. Census Bureau 175 United States Census Bureau. “2020 Census Redistricting Data (Public Law 94-171): P1: Race.” 952 2,880 3,986 4,630 5,642 5,881 5,977 6,174 6,442 6,906 7,053 6,652 7,633 7,702 7,836 0 1,000 2,000 3,000 4,000 5,000 6,000 7,000 8,000 9,000 Population Year ---PAGE BREAK--- Section Seven: City of Perry Community Profile Dallas County Hazard Mitigation Plan I 2023 159 Figure PER.2: City of Perry ---PAGE BREAK--- Section Seven: City of Perry Community Profile Dallas County Hazard Mitigation Plan I 2023 160 The young, elderly, and minority populations may be more vulnerable to certain hazards than other groups. Looking at Perry’s population: • 36.5% is non-white. Since 2010, Perry became more racially diverse. In 2010, 20.9% of the Perry’s population was non-white. By 2020, 36.5% was non-white.176 177 • 38.9 median age. The median age of Perry was 38.9 years old in 2020. The population grew older since 2010, when the median age was 33.8.178 179 Figure PER.3: Population by Age Cohort and Sex (2020) Source: U.S. Census Bureau4 The figure above shows Perry’s population percentage broken down by sex and five-year age groups. Perry’s population is relatively stable with most of the population spread out between different age groups. This indicates that the population is likely to remain stable in the future. 176 United States Census Bureau. “2020 Census Redistricting Data (Public Law 94-171): P1: Race.” 177 United States Census Bureau. “2010 Census Redistricting Data (Public Law 94-171): P1: Race.” 178 United States Census Bureau. “2020 Census Bureau American Community Survey: S0101: Age and Sex.” 179 United States Census Bureau. “2010 Census Bureau American Community Survey: S0101: Age and Sex.” 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Under 5 5 to 9 10 to 14 15 to 19 20 to 24 25 to 29 30 to 34 35 to 39 40 to 44 45 to 49 50 to 54 55 to 59 60 to 64 65 to 69 70 to 74 75 to 79 80 to 84 85 & Over Percentage of the Population Years Female % Male % ---PAGE BREAK--- Section Seven: City of Perry Community Profile Dallas County Hazard Mitigation Plan I 2023 161 Employment and Economics Low-income populations, long distance commuters, and the unemployed may be more vulnerable to certain hazards than other groups. Perry’s population has: • 14% of people living below the poverty line. The poverty rate (14%) in Perry was higher than the state’s poverty rate (11.1%) in 2020. 180 • $47,802 median household income. Perry’s median household income in 2020 ($47,802) was about $14,000 lower than the state ($61,836). 181 • 9.2% unemployment rate. In 2020 Perry had a higher unemployment rate compared to the state (3.9%).182 • 31% of workers commuted 30 minutes or more to work. Fewer workers in Perry commuted 30 minutes or more to work than workers commuting less than 15 minutes (31% compared to 47.3%).183 Major Employers Major employers for the city include Hy-Vee, Perry Community Schools, Dallas County Hospital, Percival Scientific, Weise Corporation, Progressive Foundry, and the City of Perry. According to the local planning team, approximately 1,900 residents commute to other communities for work. Housing The age of housing may indicate which housing units were built prior to the development of state building codes. Vacant housing stock may also be more vulnerable to hazard events if it is poorly maintained. Unoccupied housing may also suggest that future development may be less likely to occur. Communities with a substantial number of mobile homes may be more vulnerable to the impacts of high winds, tornadoes, and severe thunderstorms if those homes are not anchored correctly. Renter-occupied housing depends on the initiative of landlords for proper maintenance and retrofitting to be resilient to disasters. They are less likely than homeowners to have flood insurance, or to know their risks to flooding and other hazards. • 67.6% of housing built prior to 1970. Perry has a greater share of housing built prior to 1970 than the state (67.6% compared to 50.4%).184 • 9.1% of housing units vacant. Since 2010, Perry’s vacancy rate decreased. In 2010 the vacancy rate was 12.2%. By 2020, 9.1% of housing units were vacant. 185 186 180 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 181 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 182 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 183 United States Census Bureau. “2020 Census Bureau American Community Survey: S0802: Means of Transportation to Work by Selected Characteristics.” 184 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 185 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 186 United States Census Bureau. “2010 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” ---PAGE BREAK--- Section Seven: City of Perry Community Profile 162 Dallas County Hazard Mitigation Plan I 2023 • 4.6% mobile and manufactured housing. The City of Perry had a greater share of mobile and manufactured housing compared to the state (3.6%).187 • 41.9% renter-occupied. The rental rate of Perry was 41.9% in 2020. The percentage increased since 2010, when renter occupied housing was at 39.7%.188 189 The city hosts approximately 80 mobile home units located in the Northgate Estates at 2801 1st Avenue in the northwest corner of the city. Governance A community’s governance indicates the number of boards or offices that may be available to help implement hazard mitigation actions. Perry has a mayor, a five-member city council, and the following offices. • City Administrator • Clerk/Treasurer • Attorney • Chief of Police • Fire Chief • Wastewater Plant Superintendent • Water Superintendent • Public Works Director • Airport Manager • City Building Inspector • Economic Development Director • Library Director • Parks and Recreation Director • GIS/Zoning Administrator • City Finance Officer Capability Assessment The capability assessment consisted of a Capability Assessment Survey completed by the jurisdiction and a review of local existing policies, regulations, plans, and the programs. The survey is used to gather information regarding the jurisdiction’s planning and regulatory capability; administrative and technical capability; fiscal capability; and educational and outreach capability. 187 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 188 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 189 United States Census Bureau. “2010 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” ---PAGE BREAK--- Section Seven: City of Perry Community Profile Dallas County Hazard Mitigation Plan I 2023 163 Table PER.2: Capability Assessment Survey Components/Subcomponents Yes/No Planning & Regulatory Capability Comprehensive Plan Yes Capital Improvements Plan Yes Economic Development Plan Yes Emergency Operations Plan Yes Floodplain Management Plan Yes Storm Water Management Plan No Zoning Ordinance Yes Subdivision Regulation/Ordinance Yes Floodplain Ordinance Yes Building Codes Yes National Flood Insurance Program Yes Community Rating System No Other (if any) Administrative & Technical Capability Planning Commission Yes Floodplain Administration Yes GIS Capabilities No Chief Building Official Yes Civil Engineering Yes Local Staff Who Can Assess Community’s Vulnerability to Hazards Yes Grant Manager Yes Mutual Aid Agreement Yes Other (if any) Fiscal Capability Capital Improvement Plan/ 1 & 6 Year Plan Yes Applied for grants in the past Yes Awarded a grant in the past Yes Authority to Levy Taxes for Specific Purposes such as Mitigation Projects Yes Gas/Electric Service Fees N/A Storm Water Service Fees Yes Water/Sewer Service Fees Yes Development Impact Fees Yes General Obligation Revenue or Special Tax Bonds Yes Other (if any) Education & Outreach Capability Local citizen groups or non-profit organizations focused on environmental protection, emergency preparedness, access and functional needs populations, etc. Ex.

Each plan is listed below along with a short description of how it is integrated with the hazard mitigation plan. The city will seek out and evaluate any opportunities to integrate the results of the current hazard mitigation plan into other planning mechanisms and updates. Grants and Funding The City of Perry’s funds are sufficient to budget for small capitol projects or equipment expenditures. However, the city funds are not sufficient to pursue major capitol projects without requiring additional debts. The city has been bookmarked a large portion of funds to the current renovations of the Wastewater Treatment Plant. The city’s tax base has not grown like other cities in the Des Moines metro area with the older homes and reduced taxable valuations of commercial properties in the State of Iowa. Certain hazard mitigation plans are included in the municipal budget including the Iowa Street Wetland project to assist in controlling storm water run off on the east side of Perry and the Frog Creek Stabilization Project including tree clearing and bank reconstruction. Over the last five years, the city has applied for various grants and has been awarded the IDOT General Aviation Vertical Infrastructure Grant, RISE Grant Downtown Street Project, 2020 Housing Sustainability Grant-Owner Occupied Housing Renovation, Iowa Finance Authority-Wastewater and Drinking Water Treatment Financial Assistance Program, and the FEMA Assistance to Firefighters Grant. Building Codes (2021) The building code sets standards for constructed buildings and structures. The city has adopted the 2018 International Building Codes with multiple amendments made. These codes regulate and govern the conditions and maintenance of all property, buildings, and structures by providing the standards for supplied utilities, facilities, and other physical things and conditions essential to ensure that structures are safe, sanitary, and fit for occupation and use. ---PAGE BREAK--- Section Seven: City of Perry Community Profile Dallas County Hazard Mitigation Plan I 2023 165 Capital Improvements Plan (2021) The capital improvement plan outlines large purchases and projects that the city would like to pursue. Projects identified in the plan include Storm water projects, upsizing of culverts and drainage structures, regular maintenance for drainage structures, upgrading storm sewer systems, regular maintenance for the storm sewer system, improving transportation routes for drainage, and bridge improvements. The city plans to install new municipal wells, upsize water distribution pipes, install water meters for residential structures, update electrical distribution systems, bury powerlines, and install emergency generators in critical facilities. Improvements are planned for the existing fire hall, public works facility, water treatment facility, and other existing community owned structures. New construction of community owned structures is also planned. The capital improvement plan also includes roadway improvement projects and new housing projects. This plan is updated yearly. Comprehensive Plan (2013) The comprehensive plan is designed to guide the future actions and growth of the city. It incorporates some of the goals and objectives included in the HMP. The Comprehensive Plan encourages infill development, identifies areas that need emergency shelter, and encourages preservation of open space in hazard prone areas. There are plans to include goals and objectives aimed at Safe Growth in future updates of the plan. Zoning Ordinance (2021), Floodplain Ordinance (2003), and Subdivision Regulations The Zoning Ordinances are continually updated as needed and the corresponding Floodplain Ordinance will be updated in the coming years with the Zoning Ordinance scheduled for update in 2023 and the Subdivision Regulations being updated in 2024. The Ordinances contain floodplain maps, discourage development in the floodplain, and require more than one foot of elevation above Base Flood Elevation in the floodplain. Future updates will include an identification of floodplain areas as parks of open space. The Ordinances also discourage development near chemical storage sites and, in future updates, will consider wildfire and the wildland urban interface. Water System Emergency Response Plan (2020) Water system emergency response plans ensure the drinking water systems that serve the City of Perry are prepared to supply customers with drinking water in the event of an emergency. It includes identifying potential emergencies and how the utility will ensure water delivery in specific scenarios. Wellhead Protection Plan (2000) The purpose of wellhead protection plans is to protect the public drinking water supply wells from contamination. It includes identifying potential sources of groundwater contamination in the area. Future Development Trends In the last five years, many new developments have taken place in Perry. A tax abatement program has assisted in the building of 61 new housing units throughout the city with approximately 25 new homes having been built in the Sunflower addition north of the elementary school. Three new apartment buildings have also been built, adding an additional 100 new units to the city’s apartment inventory. None of the new buildings were built in the floodplain or other hazardous area. In the next five years, a certified industrial site is planned to be built on the southeast corner of the city limits. Additional plans show possible development between Park and ---PAGE BREAK--- Section Seven: City of Perry Community Profile 166 Dallas County Hazard Mitigation Plan I 2023 North Street in the northeast corner of city limits. A second apartment building is planned for the 28th Street and McKinley area. Community Lifelines Transportation Perry’s major transportation corridors include State Highway 141 and State Highway 144. The most traveled route is Highway 141 with an average of 7,200 vehicles daily, 640 of which are trucks.190 The nearest airport is Perry Municipal Airport, located just west of the city along a main transportation route. Willis Avenue, 8th Street, and 10th Street are additional routes of concern identified by the local planning team and multiple critical facilities are located along main transportation routes including Perry Wastewater Treatment facility at Highway 141 and Ivy Pace. Transportation information is important to hazard mitigation plans because it suggests possible evacuation corridors in the community, as well as areas more at risk of transportation incidents. The local planning team identifies Highway 141 and 144 as potentially having chemicals regularly transported, but that the exact substances are unknown. No major chemical spills or other significant transportation events have occurred within the city. 190 Iowa Department of Transportation. 2020. "Iowa Traffic Data".

The selected hazards were prioritized by the local planning team based on historical hazard occurrences, potential impacts, and the community’s capabilities. For additional discussion regarding area-wide hazards, please see Section Four: Risk Assessment. Hazardous Materials Release Hazardous materials release has been identified as a top concern by the local planning team due to the potential release of ammonia or chlorine gas from the Perry Water Department and Tyson Foods. Both locations are located on the west side of Perry and prevailing winds may pose a danger to the community it released. The city has not experienced occurrences of hazardous materials release and does not have any actions or projects in place to reduce the risk to this hazard. To reduce future risk of hazardous materials releases, the city plans to ensure the Water Department and Tyson Foods maintain property safety measures. Infrastructure Failure The local planning team identified this as a top hazard due to past occurrences of flooding in 1993 interrupting water production and wastewater management and the 2020 Derechos causing power disruption due to numerous downed power lines. According to the local planning team, the top concern of infrastructure failure is the loss of drinking water and power for heating and cooling. The NCEI database records 13 instances of heavy rainfall having occurred in Perry, with 2014, 2015, and 2016 having experienced three, two, and three heavy rainfall events respectively. The city has completed action to reduce their risk including renovations to the wastewater treatment plant with a projected completion date in 2024, annually updating water lines at the water plant, and a three-year plan by Alliant Energy to replace power poles and bury power lines in the southeast portion of the city. Future planning actions include installing, updating, and replacing generators at the emergency shelters located at Perry McCreary Center, Perry City Hall, the Library, and the Public Safety Building. Severe Thunderstorms (Includes Hail and Lightning) Severe thunderstorms are a regular part of the climate and weather for Perry. These storms can cause damage through heavy rain, lightning strikes, hail, and high winds. The NCEI reports 52 instances of severe thunderstorms occurring in Perry from 1996 to 2021. The typical damage seen caused by these severe thunderstorms was toppled trees and power poles or wires due to high winds. These storms caused a total of $413,000 worth of structural damage across the impacted zones. The most significant concern identified by the local planning team was the flooding of city streets, homes, and businesses. The city has experienced various rain events over three to four inches and storm drain and sanitary sewer lines backing up. To reduce the risk from this hazard, storm sewers have been inspected and are cleaned regularly, repairs to sewer lines, storm lines, and a sump pump made, and a water retention area is being created near Iowa Street and 26th Street to assist in drainage of rainwater. Additionally, the local planning team plans to further their risk reduction by continuing the repair of aging storm water systems and cleanup of the Frog Creek areas to allow for quicker and more efficient drainage. Respondents to the public survey reported that past impacts from this hazard include flooding near the Raccoon River. ---PAGE BREAK--- Section Seven: City of Perry Community Profile Dallas County Hazard Mitigation Plan I 2023 175 Severe Winter Storms Severe winter storms are a regular part of the climate and weather for Perry. Severe winter storms include blizzards, ice accumulation, heavy snow, and winter storms. These storms can cause power outages during bitterly cold temperatures, road closures, and economic impacts. Perry has received multiple heavy snow falls including 14 inches in 1998, 16 inches in 2004, and 3 inches of ice pellets in 2008. According to the NCEI, there were 79 winter storm events in Dallas County from 1996 to 2021. One of these storm events in 2012 resulted in 7.8 inches of snowfall in Adel. These 79 events resulted in $6,613,680 in property damages, with no injuries or deaths reported. Additionally, the USDA Risk Management Agency reported almost $375,000 in crop damages from severe winter storm events from 2000 to 2021. The most significant concern identified by the local planning team is the loss of power for extended periods during extreme cold. To reduce the risk from this hazard, Alliant Energy is working to bury existing power lines. Tornado and Windstorm The local planning team identified tornado and windstorm as a top hazard due to their prevalence in the area and potential for damage and loss of life. Windstorms are common across the county and can cause property and tree damage and brief power outages. Tornadoes are much less common, but the impacts can be far greater. Between 1996 and 2021, the NCEI recorded 31 high wind events in Dallas County and two F0 tornadoes in Perry, one in May 1999 and the second in June 2000. The May 1999 tornado resulted in $2,000 of property damage. No deaths or injuries were reported from either tornado. The local planning team also reported having experienced Derecho storms in 2020 that caused power disruptions. The most significant concern identified by the local planning team due to loss of power and damage to structures. The top concerns included tree canopies taking power lines down, overhead lines being damaged, and damage to aging housing structure. The local planning team is also concerned with the lack of adequate storm shelters. To reduce the risk from this hazard, the city is currently adopting a franchise fee to assist in removing damaged, dying, or dead trees as well as those presenting hazards to travel. The city has implemented a tax abatement program that is helping create new housing and improving existing structures. Building codes have been updated across the city and rental inspections are being made.

Major waterways in the area include Middle Racoon River and Racoon River. Demographics Redfield’s population in 2020 was 731. The following figure displays the historical population trend from 1880 to 2020. This figure indicates that the population of Redfield increased from 1880 to 1940, fluctuated from 1940 to 1980, and has generally declined since. A declining population can lead to more unoccupied housing that is not being maintained and is then at risk to high winds and other hazards. Furthermore, with fewer residents, there is decreasing tax revenue for the community, which can make implementation of mitigation projects fiscally challenging. Redfield’s population accounted for 0.7% of Dallas County’s population in 2020.195 Figure RED.1: Population 1880 - 2020 Source: U.S. Census Bureau 195 United States Census Bureau. “2020 Census Redistricting Data (Public Law 94-171): P1: Race.” 394 397 509 659 770 870 898 892 966 921 959 883 833 835 731 0 200 400 600 800 1,000 1,200 Population Year ---PAGE BREAK--- Section Seven: City of Redfield Community Profile Dallas County Hazard Mitigation Plan I 2023 183 Figure RED.2: City of Redfield ---PAGE BREAK--- Section Seven: City of Redfield Community Profile Dallas County Hazard Mitigation Plan I 2023 184 The young, elderly, and minority populations may be more vulnerable to certain hazards than other groups. Looking at Redfield’s population: • 6.3% is non-white. Since 2010, Redfield became more racially diverse. In 2010, 4.1% of the Redfield’s population was non-white. By 2020, 6.3% was non-white.196 197 • 43 median age. The median age of Redfield was 43 years old in 2020.

Redfield’s population is relatively stable with most of the population spread out between different age groups. This indicates that the population is likely to remain stable in the future. 196 United States Census Bureau. “2020 Census Redistricting Data (Public Law 94-171): P1: Race.” 197 United States Census Bureau. “2010 Census Redistricting Data (Public Law 94-171): P1: Race.” 198 United States Census Bureau. “2020 Census Bureau American Community Survey: S0101: Age and Sex.” 199 United States Census Bureau. “2010 Census Bureau American Community Survey: S0101: Age and Sex.” 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Under 5 5 to 9 10 to 14 15 to 19 20 to 24 25 to 29 30 to 34 35 to 39 40 to 44 45 to 49 50 to 54 55 to 59 60 to 64 65 to 69 70 to 74 75 to 79 80 to 84 85 & Over Percentage of the Population Years Female % Male % ---PAGE BREAK--- Section Seven: City of Redfield Community Profile Dallas County Hazard Mitigation Plan I 2023 185 Employment and Economics Low-income populations, long distance commuters, and the unemployed may be more vulnerable to certain hazards than other groups. Redfield’s population has: • 8.7% of people living below the poverty line. The poverty rate in Redfield was lower than the state’s poverty rate (11.1%) in 2020. 200 • $68,194 median household income. Redfield’s median household income in 2020 ($68,194) was about $6,400 higher than the state ($61,836). 201 • 0.9% unemployment rate. In 2020 Redfield had a lower unemployment rate compared to the state (3.9%).202 • 46.2% of workers commuted 30 minutes or more to work. More workers in Redfield commuted 30 minutes or more to work than workers commuting less than 15 minutes (46.2% compared to 16.8%).203 Major Employers Major employers for the city include SCG Services, Heartland Co-Op, Stine Seed, and West Central Valley Middle School. According to the local planning team, a large percentage of residents commute to other communities for work, such as Adel and West Des Moines. Housing The age of housing may indicate which housing units were built prior to the development of state building codes. Vacant housing stock may also be more vulnerable to hazard events if it is poorly maintained. Unoccupied housing may also suggest that future development may be less likely to occur. Communities with a substantial number of mobile homes may be more vulnerable to the impacts of high winds, tornadoes, and severe thunderstorms if those homes are not anchored correctly. Renter-occupied housing depends on the initiative of landlords for proper maintenance and retrofitting to be resilient to disasters. They are less likely than homeowners to have flood insurance, or to know their risks to flooding and other hazards. • 72.1% of housing built prior to 1970. Redfield has a greater share of housing built prior to 1970 than the state (72.1% compared to 50.4%).204 • 17.4% of housing units vacant. Since 2010, Redfield’s vacancy rate increased. In 2010 the vacancy rate was 16.9%. By 2020, 17.4% of housing units were vacant. 205 206 200 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 201 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 202 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 203 United States Census Bureau. “2020 Census Bureau American Community Survey: S0802: Means of Transportation to Work by Selected Characteristics.” 204 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 205 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 206 United States Census Bureau. “2010 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” ---PAGE BREAK--- Section Seven: City of Redfield Community Profile 186 Dallas County Hazard Mitigation Plan I 2023 • 4.9% mobile and manufactured housing.

Each applicable planning mechanism is listed below along with a short description of how it is integrated with the hazard mitigation plan. The city will seek out and evaluate any opportunities to integrate the results of the current hazard mitigation plan into other planning mechanisms and updates. Funding and Grants The Waukee municipal funds are limited to maintaining current facilities and municipal services. There are currently no large projects lined up that have funds dedicated. Municipal funds have been decreasing in recent years due to rising operational costs. The city has applied for FEMA grants for a new water plant generator in the last five years but have not been awarded any grants since 2010. Capital Improvement Plan The capital improvement plan outlines large purchases and projects that the city would like to pursue. Projects identified in the plan include upsizing of culverts and drainage structures, regular maintenance for drainage structures, regular maintenance for the storm sewer system, improving transportation routes for drainage. The plan also includes installing water meters for residential structures and installing emergency generators in critical facilities as projects the city would like to pursue. ---PAGE BREAK--- Section Seven: City of Redfield Community Profile Dallas County Hazard Mitigation Plan I 2023 189 Comprehensive Plan (1997) The comprehensive plan is designed to guide the future actions and growth of the city. The city’s Comprehensive Plan has not been updated since 1997. There are currently no plans or timeline to update the comprehensive plan. Floodplain Regulations (2019), Zoning Ordinance (2019), and Subdivision Regulations (2001) The city’s Floodplain Regulations contain floodplain maps of the city. The floodplain regulations do not limit development or population density within the floodplain. The Zoning Regulations for Redfield do not discourage development near chemical storage sites or along major transportation routes. There is no current plan or timeline to update the Zoning Ordinance, Floodplain Ordinance, or Subdivision Regulations. Water System Emergency Response Plan (2006) Water system emergency response plans ensure the drinking water systems that serve the City of Redfield are prepared to supply customers with drinking water in the event of an emergency. It includes identifying potential emergencies and how the utility will ensure water delivery in specific scenarios. Wellhead Protection Plan The purpose of wellhead protection plans is to protect the public drinking water supply wells from contamination. It includes identifying potential sources of groundwater contamination in the area. Future Development Trends In the last five years a Dollar General has been established in the city. The structure was not developed in the floodplain or near other hazardous areas. The city does not currently have new housing, business, or industry development planned for the next five years. Community Lifelines Transportation Redfield’s major transportation corridors include County Highways F59, F60, and P46. The most traveled route is Highway F60, with an average of 1,750 vehicles per day.210 The nearest airport, Guthrie Center Municipal Airport, is located about 14 miles northwest of Redfield. Transportation information is important to hazard mitigation plans because it suggests possible evacuation corridors in the community, as well as areas more at risk of transportation incidents. There are no regularly transported chemicals along the local routes and no chemical spills or other significant transportation events have occurred locally 210 Iowa Department of Transportation. 2020.

The selected hazards were prioritized by the local planning team based on historical hazard occurrences, potential impacts, and the community’s capabilities. For additional discussion regarding area-wide hazards, please see Section Four: Risk Assessment. Flooding According to the NCEI, there were four flood events in Redfield from 1996 to 2021. These events resulted in $570,000 in property damage, but no injuries or fatalities. The local planning team indicated that a past flood incident occurred due to an ice jam. The top concerns of the planning team are the potential of power outages and displacement of residents. No projects are currently planned to reduce risk for flooding; however, the planning team indicated that a flood control structure such as a river wall system is needed in the future. Redfield has two NFIP policies in-force for $280,000 as of June 2022. A FEMA Flood Insurance Study for Dallas County, including Redfield, was revised in December 2018, and can be viewed on FEMA’s Flood Map Service Center: According to the IDNR, there are zero repetitive flood loss properties Redfield. 214 Federal Emergency Management Agency. 2022. “FEMA Flood Map Service Center.” Accessed December 2022. ---PAGE BREAK--- Section Seven: City of Redfield Community Profile 194 Dallas County Hazard Mitigation Plan I 2023 Severe Thunderstorms (Includes Hail and Lightning) Severe thunderstorms are a regular part of the climate and weather for Redfield. These storms can cause damage through lightning strikes, hail, and high winds. The NCEI reports 11 instances of severe thunderstorms occurring in Redfield from 1998 to 2019. The typical damage seen caused by these severe thunderstorms was toppled trees and power poles or wires due to high winds. These storms caused a total of $62,000 worth of damage across Dallas County. Additionally, the NCEI reported 10 instances of hail occurring in Redfield. The hail ranged from 0.75 inches to 1.75 inches that resulted in $71,000 of property damage. The local planning team is highly concerned with power outages resulting from this hazard. The planning team did not indicate any specific actions or projects implemented to reduce risk and impacts from this hazard. There are no current actions or projects planned for the city to reduce risk of severe thunderstorms either. Severe Winter Storms Severe winter storms are a regular part of the climate and weather for Redfield. Severe winter storms include blizzards, ice accumulation, heavy snow, and winter storms. These storms can cause power outages during bitterly cold temperatures, road closures, and economic impacts. According to the NCEI, there were 79 winter storm events in Dallas County from 1996 to 2021. These events resulted in $6,613,680 in property damages, with no injuries or deaths reported. Additionally, the USDA Risk Management Agency reported almost $375,000 in crop damages from severe winter storm events from 2000 to 2021. The local planning team is highly concerned with power outages resulting from this hazard. The planning team did not indicate any specific actions or projects implemented to reduce risk and impacts from this hazard. Approximately 25% of the town’s power lines have been buried, making them less susceptible to breaking during severe storms. The towns snow removal resources are sufficient to deal with large snow falls events. There are no current actions or projects planned for the city to reduce risk of severe winter storms. Tornado and Windstorm The local planning team identified tornado and windstorm as a top hazard due to their prevalence in the area and potential for damage and loss of life. Windstorms are common across the county and can cause property and tree damage and brief power outages. Tornadoes are much less common, but the impacts can be far greater. Between 1996 and 2021, the NCEI recorded 31 high wind events in Dallas County. No tornados are recorded as having occurred in Redfield. The city has experienced derecho winds that resulted in downed trees and power lines. Downed tree limbs and power lines can result in power outages across the city, which is the top concern of the local planning team. To minimize the effects of tornadoes and windstorms, the city has removed some dead ash trees to reduce the number of fallen trees during a wind event. There are no additional projects planned for the city to reduce risk of tornado and windstorm. ---PAGE BREAK--- Section Seven: City of Redfield Community Profile Dallas County Hazard Mitigation Plan I 2023 195 Mitigation Strategy Continued Mitigation and Strategic Actions Mitigation Action Safe Room Description Construct a community saferoom in accordance with FEMA standards.

Van Meter’s population has: • 1.5% of people living below the poverty line. The poverty rate in Van Meter was lower than the state’s poverty rate (11.1%) in 2020. 220 • $111,736 median household income. Van Meter’s median household income in 2020 ($111,736) was $49,900 higher than the state ($61,836). 221 • 1.5% unemployment rate. In 2020 Van Meter had a lower unemployment rate compared to the state (3.9%).222 • 22.7% of workers commuted 30 minutes or more to work. More workers in Van Meter commuted 30 minutes or more to work than workers commuting less than 15 minutes (22.7% compared to 16.3%).223 Major Employers Major employers for the city include Van Meter Public Schools, All American Turf, City Hall, The Law Shop, Integrated Sales, EBank, the local post office, Casey’s, and Dahl’s. According to the local planning team, a large percentage of residents commute to other communities for work, such as Waukee, Des Moines, West Des Moines, Ankeny, and Grimes. Housing The age of housing may indicate which housing units were built prior to the development of state building codes. Vacant housing stock may also be more vulnerable to hazard events if it is poorly maintained. Unoccupied housing may also suggest that future development may be less likely to occur. Communities with a substantial number of mobile homes may be more vulnerable to the impacts of high winds, tornadoes, and severe thunderstorms if those homes are not anchored correctly. Renter-occupied housing depends on the initiative of landlords for proper maintenance and retrofitting to be resilient to disasters. They are less likely than homeowners to have flood insurance, or to know their risks to flooding and other hazards. • 39.4% of housing built prior to 1970. Van Meter has a smaller share of housing built prior to 1970 than the state (39.4% compared to 50.4%).224 • 4.6% of housing units vacant. Since 2010, Van Meter’s vacancy rate decreased. In 2010 the vacancy rate was 6.4%. By 2020, 4.6% of housing units were vacant. 225 226 220 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 221 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 222 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 223 United States Census Bureau. “2020 Census Bureau American Community Survey: S0802: Means of Transportation to Work by Selected Characteristics.” 224 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 225 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 226 United States Census Bureau. “2010 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” ---PAGE BREAK--- Section Seven: City of Van Meter Community Profile 202 Dallas County Hazard Mitigation Plan I 2023 • 0% mobile and manufactured housing. The City of Van Meter had a smaller share of mobile and manufactured housing compared to the state (3.6%).227 • 12.6% renter-occupied. The rental rate of Van Meter was 12.6% in 2020. The percentage decreased since 2010, when renter occupied housing was at 14.4%.228 229 Governance A community’s governance indicates the number of boards or offices that may be available to help implement hazard mitigation actions. Van Meter has a mayor, a five-member city council, and the following offices. • City Administrator • Clerk/Treasurer • Deputy Clerk • Police Chief • Fire Chief • Library Director • Library Board • Parks Coordinator • Parks and Recreation Board • Public Works Director • Public Works Operator Capability Assessment The capability assessment consisted of a Capability Assessment Survey completed by the jurisdiction and a review of local existing policies, regulations, plans, and the programs.

Each plan is listed below along with a short description of how it is integrated with the hazard mitigation plan. The city will seek out and evaluate any opportunities to integrate the results of the current hazard mitigation plan into other planning mechanisms and updates. Comprehensive Plan The comprehensive plan is designed to guide the future actions and growth of the city. It incorporates some of the goals and objectives included in the HMP. The Comprehensive Plan discusses floodplain and slope erosion. The plan limits density in areas adjacent to known hazardous areas and encourages preservation of open space in hazard prone areas. Funding and Grants The city’s funds are limited, and any capital projects must be incorporated into the budget several years in advanced. Currently, the city has bookmarked funds to install a new well. Municipal funds have increased over recent years. Over the last five years, the city has not applied for or been awarded any hazard mitigation related grants. Zoning Ordinance, Floodplain Ordinance, and Subdivision Regulations (2022) The city recently updated their Subdivision Regulations but have not updated their Zoning or Floodplain Ordinance in the last few years. The Floodplain Ordinances include floodplain maps and prohibit development and limit population density within the floodplain. The Zoning Ordinances do not discourage or limit development in areas considered hazardous. There are no current timelines for updating any of the ordinances. Future Development Trends In the last five years, there have been three new housing developments in the city. The area south of Highway F90 is designated as an area of improvement. A recreation complex was developed in the floodplain off Highway R16. In the next five years, a daycare center is planned for Grand Ridge Estates. No other housing or business developments are currently planned for the near future. A future land use map for the city can be seen in the following figure. ---PAGE BREAK--- Section Seven: City of Van Meter Community Profile Dallas County Hazard Mitigation Plan I 2023 205 Figure VAN.4: Future Land Use Map ---PAGE BREAK--- Section Seven: City of Van Meter Community Profile Dallas County Hazard Mitigation Plan I 2023 206 Community Lifelines Transportation Van Meter’s major transportation corridors include County Highway R16 and County Highway F90. The most traveled route is Highway R16 with an average of 3,050 vehicles daily.230 According to the planning team, ethanol and other hazardous materials are regularly transported along local routes but no chemical spills have occurred in the area. Van Meter has one rail line, the Iowa Interstate Railroad, which passes through the northern part of the city. The nearest airport, the Des Moines International Airport, is located about 14 miles east of Van Meter. Transportation information is important to hazard mitigation plans because it suggests possible evacuation corridors in the community, as well as areas more at risk of transportation incidents. Hazardous Materials Based on the National Pipeline Mapping System, the nearest gas transmission pipeline to Van Meter is just south of De Soto.

The selected hazards were prioritized by the local planning team based on historical hazard occurrences, potential impacts, and the community’s capabilities. For additional discussion regarding area-wide hazards, please see Section Four: Risk Assessment. Dam and Levee Failure Although not identified as a hazard of top concern by the local planning team, this hazard is being profiled due to the presence of a local levee. The Van Meter Levee spans approximately 1.8 miles in length and protects 124 residents and 49 structures, according to the USACE’s National Levee Database. The levee has not been inspected and thus has no risk rating. The levee is locally constructed, operated, and maintained. There is no recorded instance of levee failure, according to the USACE. An illustration of the levee can be seen in Figure 7.

Please refer to FEMA's Flood Map Service Center for the current FIRM information. ---PAGE BREAK--- Section Seven: City of Van Meter Community Profile 212 Dallas County Hazard Mitigation Plan I 2023 Flooding According to the NCEI, there were 20 flood events in Van Meter from 1996 to 2021. These events resulted in $1,328,000 in property damage, but no injuries or fatalities. The local planning team indicated that in July 1993, the Raccoon River flooded at 1.3 times the 100-year flood discharge level and damaged all of the land adjacent to the river. Another flood destroyed the recreation fields and buildings in the area. Since then, the city has repaired the buildings and recreation fields. The recreation complex remains a concern due to its proximity to the river. No projects are currently planned to reduce risk for flooding; however, the planning team indicated that a flood control structure such as a river wall system is needed in the future. Van Meter has six NFIP policies in-force for $941,000 as of June 2022. A FEMA Flood Insurance Study for Dallas County, including Van Meter, was revised in December 2018, and can be viewed on FEMA’s Flood Map Service Center: According to the IDNR, there are zero repetitive flood loss properties in Van Meter. Hazardous Materials Release The planning team identified this as a top hazard due to its proximity to Interstate 80 and the Iowa Interstate Railroad. The railroad, which tracks directly through the city, regularly transports ethanol and other hazardous materials. The community is situated south of I-80 and is located in a river valley. As such, the planning team is concerned that aerosol hazardous materials could travel south from the interstate, depending on how the wind is blowing. According to the Pipeline and Hazardous Materials Safety Administration, there have been two small transportation-related chemical releases in Van Meter. However, there were no reported damages, injuries, evacuations, or fatalities as a result of these minor spills. To reduce the risk of an event and its impacts, the city has enforced a 25-mph train speed limit though town. The community has also performed tabletop exercises to better prepare for a potential train derailment. To reduce risk in the future, the planning team indicated that continued adherence to safety protocols by the Iowa Interstate Railroad and continued track maintenance are necessary. Infrastructure Failure The city’s infrastructure experiences various problems in each system. The wastewater system has storm water leaching into cracked sewer pipes resulting in high E. coli levels in the lagunes. The city’s water system has had several water pipes burst and need replacement. The water pipes in the community need to be completely renovated and the road conditions in some areas of town are of concern to the local community. Repairs to the broken pipes have included Cure- In-Place-Pipe Lining in June and July 2022 and replacing broken water pipes as they were found. To reduce the risk of infrastructure failure, the city plans to continue with consistent maintenance of roads and other infrastructure. Severe Thunderstorms (Includes Hail and Lightning) Severe thunderstorms are a regular part of the climate and weather in the Midwest. These storms can cause damage through heavy rain, lightning strikes, hail, and high winds. The NCEI reports six instances of severe thunderstorms occurring in Van Meter from 1996 to 2021. The typical damage seen caused by these severe thunderstorms was toppled trees and power poles or wires due to high winds. These storms caused a total of $112,000 worth of structural damage across the impacted zones. ---PAGE BREAK--- Section Seven: City of Van Meter Community Profile Dallas County Hazard Mitigation Plan I 2023 213 The local planning team reports there have not been any major events that have caused damage to city or community facilities and no repairs due to severe thunderstorms have been needed. A future concern for the community includes a severe thunderstorm that results in the electricity going out and damage to city facilities. In the event of a severe thunderstorm resulting in a power outage, several critical facilities in Van Meter do not have generators including City Hall, Methodist Church, University Kids Daycare, and the Van Meter School District buildings. Installing generators at these locations and having insurance on the buildings for any damage a severe storm can reduce the risk to the community when severe thunderstorms occur. Some of the critical facilities have weather radios for storm warnings. The local planning team hopes to sign up for the county’s weather alert system and encourage community members to sign up with signup instructions in the city newsletter or utility bill. Severe Winter Storms Severe winter storms are a regular part of the climate and weather for Van Meter. Severe winter storms include blizzards, ice accumulation, heavy snow, and winter storms. These storms can cause power outages during bitterly cold temperatures, road closures, and economic impacts. According to the NCEI, there were 79 winter storm events in Dallas County from 1996 to 2021. These events resulted in $6,613,680 in property damages, with no injuries or deaths reported. Additionally, the USDA Risk Management Agency reported almost $375,000 in crop damages from severe winter storm events from 2000 to 2021. Significant concerns identified by the local planning team are residents becoming stranded during a storm and being exposed to the cold for too long. The local planning team reports no significant structural damage has occurred in recent years due to severe winter storms. However, the city’s snow removal resources could be improved and the city has discussed purchasing a new snow truck within the next two years. To reduce risk and impacts to this hazard, the city has designated a snow route through the community and the local planning team would like to increase education and outreach to the public regarding severe winter storms. Tornado and Windstorm The local planning team identified tornado and windstorm as a top hazard due to their prevalence in the area and potential for damage and loss of life. Windstorms are common across the county and can cause property and tree damage and brief power outages. Tornadoes are much less common, but the impacts can be far greater. Between 1996 and 2021, the NCEI recorded 31 high wind events in Dallas County and one tornado in Van Meter. The brief tornado event occurred in May 2015 with an EF0 tornado only damaging trees near the North Raccoon River. No injuries or other damages were reported. Derechos in August 2020 and December 2021 impacted the community and caused extensive damage including uprooted trees and damaged roofs. Numerous tornado warnings and watches are also common throughout the spring and summer, as noted by the planning team. To minimize the effects of tornadoes and windstorms, the city has purchased and installed a second outdoor warning siren. The city is also looking at developing an in-ground shelter at the new public safety site, as funding allows. As the community grows, additional outdoor sirens will be needed to reduce impacts of this hazard. ---PAGE BREAK--- Section Seven: City of Van Meter Community Profile 214 Dallas County Hazard Mitigation Plan I 2023 Transportation Incident This hazard was identified as a top hazard due to the city’s proximity to Interstate 80 on the northern border of the city as well as Highway 90, which sits on the southern side. The city regularly works motor vehicle accidents on both major roadways, including multiple vehicle accidents. Additionally, the Iowa Interstate Railroad intersects the middle of the community. According to the Federal Railroad Administration, there were four highway rail accidents in Van Meter from 1975-2021, with the last one occurring in 2012. These accidents resulted in in two injuries and one fatality. One concern that the local planning team noted is that any major transportation incident can shut down the main roadways in the community – including hazardous chemical incidents. A railroad derailment is also a concern as it could damage businesses that sit adjacent to the tracks. The city has worked with the Iowa State Patrol to develop traffic management to reduce the risk of roadways completely shutting down due to an incident. The city has also been trying to obtain permission from the Iowa Interstate Railroad for an emergency crossing at Wilson Street. A fully funded railroad crossing at this location is needed in the future to reduce risk to the community. ---PAGE BREAK--- Section Seven: City of Van Meter Community Profile Dallas County Hazard Mitigation Plan I 2023 215 Mitigation Strategy Continued Mitigation and Strategic Actions Mitigation Action Public Education on Hazards Description Develop and implement educational campaigns such as classes and pamphlets available in the library.

Plan Maintenance Hazard Mitigation Plans should be living documents and updated regularly to reflect changes in hazard events, priorities, and mitigation actions. These updates are encouraged to occur after every major disaster event, alongside community planning documents annual budgets and Capital Improvement Plans), during the fall before the HMA grant cycle begins, and/or prior to other funding opportunity cycles begin, including CDBG, Water Sustainability Fund, Revolving State Fund, or other identified funding mechanisms. The local planning team is responsible for reviewing and updating this community profile as changes occur or after a major event. The local planning team will include the City Administrator, Police Chief, and the Fire Chief. The plan will be reviewed annually. The public will be included in the review and revision process via council meetings, website updates, social media, and letters/doorhangers. ---PAGE BREAK--- Section Seven: City of Van Meter Community Profile 216 Dallas County Hazard Mitigation Plan I 2023 This Page is Intentionally Blank ---PAGE BREAK--- Section Seven: City of Waukee Community Profile Dallas County Hazard Mitigation Plan I 2023 217 Community Profile City of Waukee Dallas County Hazard Mitigation Plan 2023 ---PAGE BREAK--- Section Seven: City of Waukee Community Profile 218 Dallas County Hazard Mitigation Plan I 2023 Local Planning Team Table WAU.1: Waukee Local Planning Team Name Title Jurisdiction Rudy Koester Public Works Director City of Waukee, IA Clint Robinson Fire Chief City of Waukee, IA John Quinn Police Chief City of Waukee, IA Brad Deets City Administrator City of Waukee, IA Location and Geography The City of Waukee is located in southeast Dallas County and covers an area of 21.86 square miles. Major waterways in the area include Sugar Creek, Fox Creek, and Walnut Creek. Demographics Waukee’s population in 2020 was 23,940. The following figure displays the historical population trend from 1880 to 2020. This figure indicates that the population of Waukee remained relatively stable from 1880 to 1960, saw significant growth from 1960 to 2000, then increased dramatically from 2000 to 2020. Increasing populations are associated with increased hazard mitigation and emergency planning requirements for development. Increasing populations can also contribute to increasing tax revenues, allowing communities to pursue additional mitigation projects. Waukee’s population accounted for 24% of Dallas County’s population in 2020.236 Figure WAU.1: Population 1880 - 2020 Source: U.S. Census Bureau 236 United States Census Bureau. “2020 Census Redistricting Data (Public Law 94-171): P1: Race.” 245 240 292 340 375 445 473 501 687 1,577 2,227 2,512 5,126 13,790 23,940 0 5,000 10,000 15,000 20,000 25,000 30,000 Population Year ---PAGE BREAK--- Section Seven: City of Waukee Community Profile Dallas County Hazard Mitigation Plan I 2023 219 Figure WAU.2: City of Waukee ---PAGE BREAK--- Section Seven: City of Waukee Community Profile Dallas County Hazard Mitigation Plan I 2023 220 The young, elderly, and minority populations may be more vulnerable to certain hazards than other groups.

Waukee’s population has: • 3.3% of people living below the poverty line. The poverty rate in Waukee was lower than the state’s poverty rate (11.1%) in 2020. 241 • $94,371 median household income. Waukee’s median household income in 2020 ($94,371) was about $32,500 higher than the state ($61,836). 242 • 3.2% unemployment rate. In 2020 Waukee had a lower unemployment rate compared to the state (3.9%).243 • 21% of workers commuted 30 minutes or more to work. Fewer workers in Waukee commuted 30 minutes or more to work than workers commuting less than 15 minutes (21% compared to 29.2%).244 Major Employers Major employers for the city include Hy-Vee, Waukee Community School District, Holmes Murphy & Associates, Waukee Family YMCA, Access Systems, Gilcrest Jewett Lumber Co., Stivers Ford, Quad Graphics, Fleet Farm, and the City of Waukee. According to the local planning team, a large percentage of residents commute to other communities for work, such as Des Moines, West Des Moines, Clive, and Ankeny. Housing The age of housing may indicate which housing units were built prior to the development of state building codes. Vacant housing stock may also be more vulnerable to hazard events if it is poorly maintained. Unoccupied housing may also suggest that future development may be less likely to occur. Communities with a substantial number of mobile homes may be more vulnerable to the impacts of high winds, tornadoes, and severe thunderstorms if those homes are not anchored correctly. Renter-occupied housing depends on the initiative of landlords for proper maintenance and retrofitting to be resilient to disasters. They are less likely than homeowners to have flood insurance, or to know their risks to flooding and other hazards. • 6.5% of housing built prior to 1970. Waukee has a smaller share of housing built prior to 1970 than the state (6.5% compared to 50.4%).245 • 4.6% of housing units vacant. Since 2010, Waukee’s vacancy rate increased.

Each plan is listed below along with a short description of how it is integrated with the hazard mitigation plan. The city will seek out and evaluate any opportunities to integrate the results of the current hazard mitigation plan into other planning mechanisms and updates. Funding and Grants The City of Waukee’s funds are sufficient to pursue new capital projects. With rapid city growth, the city must prioritize capital projects that increase the city’s capacity. A large portion of city funds are dedicated to capital projects within the Public Works department including the sewer system, water system, streets, and storm water system. Municipal funds have increased with population growth in the city. Drainage improvements to the intersection of LA Grant and Booth Avenue are identified hazard mitigation plans that have already been completed using municipal funds. Waukee has applied for a variety of grants, some of them being the Destination Iowa Grant, Dallas County Foundation Grant, the Governor’s Traffic Safety Bureau Grants, and the State of Iowa Fireworks Safety Grant. The city has been awarded some of these grants including Dallas County Foundation Grant, TSIP, ICAAP, STBG, U-STEP, and STBG-TAP. Building Codes (2018) The building code sets standards for constructed buildings and structures. The city follows the 2018 versions of the International Building Code, International Residential Code, and International Fire Code as adopted by the State of Iowa with some local amendments. The local amendments are targeted to strengthen the structural side of buildings for winds and snow loads. Amendments relative to storm shelters is consistent with geographic regional levels of tornadic activity. Amendments specific to shaft enclosures increase resiliency to stairwell shafts for egress. Other amendments correlate IBC and IFC amendments for alignment. Comprehensive Plan (2018) The comprehensive plan is designed to guide the future actions and growth of the city. The city’s plan contains goals aimed at Safe Growth. Some of the city’s goals outlined in the plan include: limit density in areas adjacent to known hazardous areas, encourage infill development, encourage “clustering of development” in sensitive areas, and encourage preservation of open space in hazard-prone areas. The city updates the plan every 5 to 10 years to ensure previously adopted goals are still in alignment with current community goals. The next comprehensive plan update will include reference to the hazard mitigation plan and consider an analysis for areas without proper storm shelters. ---PAGE BREAK--- Section Seven: City of Waukee Community Profile Dallas County Hazard Mitigation Plan I 2023 225 Capital Improvement Plan (2022) The capital improvement plan outlines large purchases and projects that the city would like to pursue. Projects identified various storm water focused projects including upsizing of culverts and drainage structures, regular maintenance for drainage structures, upgrading storm sewer systems, and improving transportation routes for drainage. The plan also identifies widening roadways that would improve evacuations as a top project. Water distribution focused projects identified in the plan include installing new municipal wells, upsizing water distribution pipes, and installing water meters for residential structures. Construction projects identified in the plan include installing emergency generators in critical facilities, constructing a new fire hall and improving the existing hall, constructing a new police headquarters, improving the existing public works facility, and construction and improving other community owned structures. The City of Waukee’s Capital Improvement Plan is projected out seven fiscal years and is updated annually. Zoning Ordinance (2022), Floodplain Ordinance (2022), Subdivision Regulations (2021) The Floodplain Management Ordinance of the City of Waukee is currently being updated in late 2022 to ensure references to the new floodplain maps that will become effective in late 2022. The update will ensure the code meets minimum state and federal requirements to maintain our eligibility to participate in NFIP. The current Floodplain Ordinance contains floodplain maps and discourages development in the floodplain. They do not limit population density or require more than one foot of elevation above Base Flood Elevation in the floodplain. The Subdivision Regulations of Waukee restrict subdivision of land within or adjacent to the floodplain and do not allow density transfers in hazard areas. Water System Emergency Response Plan (2022) Water system emergency response plans ensure the drinking water systems that serve the City of Waukee are prepared to supply customers with drinking water in the event of an emergency. It includes identifying potential emergencies and how the utility will ensure water delivery in specific scenarios. Wellhead Protection Plan (2021) The purpose of wellhead protection plans is to protect the public drinking water supply wells from contamination. It includes identifying potential sources of groundwater contamination in the area. Future Development Trends In the last five years, there have been significant residential and commercial growth with numerous residential, commercial, and road development projects having been completed. Of the new development, one project was constructed within a floodplain, a roadway embankment constructed for NW Douglas Parkway between NW 10th St. and NW 2nd St. was determined to be classified as a dam by the Iowa DNR due to the amount of water impounded. The city has numerous single and multi-family housing developments in the planning and construction phases. These developments are in several areas of the city but are primarily located in the North, West, and South corporate limits. Several commercial development projects are also planned with most concentrated along the Grand Prairie Parkway and Hickman Road corridors. A future land use map for the city can be seen in the following figure. ---PAGE BREAK--- Section Seven: City of Waukee Community Profile Dallas County Hazard Mitigation Plan I 2023 226 Figure WAU.4: Future Land Use Map ---PAGE BREAK--- Section Seven: City of Waukee Community Profile Dallas County Hazard Mitigation Plan I 2023 227 Community Lifelines Transportation Waukee’s major transportation corridors include Interstate 80, U.S. Highway 6, Alice’s Road, and Grand Prairie Parkway. The most traveled route is Highway 6, with an average of 25,800 vehicles daily, 958 of which are trucks.251 No chemical spills have occurred locally. Infrequent closures of Interstate 80 due to weather or traffic accidents cause significant volumes of traffic detouring through the community. Two critical facilities are located along main transportation routes, including the Town Border Station No. 1 located at the intersection of W Hickman Road and NW 10th Street, and the Alice’s Road Gas Regulator Station located near the intersection of SE Alice’s Road and SE Olson Drive. Waukee has one rail line, the Union Pacific Railroad, located in the southeast portion of the city. The nearest airport, the Des Moines International Airport, is located about 12 miles southeast of Waukee. Transportation information is important to hazard mitigation plans because it suggests possible evacuation corridors in the community, as well as areas more at risk of transportation incidents.

The selected hazards were prioritized by the local planning team based on historical hazard occurrences, potential impacts, and the community’s capabilities. For additional discussion regarding area-wide hazards, please see Section Four: Risk Assessment. Severe Thunderstorms (Includes Hail and Lightning) Severe thunderstorms are a regular part of the climate and weather for Waukee. These storms can cause damage through lightning strikes, hail, and high winds. The NCEI reports 18 instances of severe thunderstorms occurring in Waukee from 1998 to 2019. The typical damage seen caused by these severe thunderstorms was toppled trees and power poles or wires due to high winds. These storms caused a total of $157,000 worth of damage. Significant concerns identified by the local planning team included the reliability of the city electrical grid. To reduce risk and impacts to this hazard, the city has begun collaborations with MidAmerican Energy Co. to convert overhead powerlines to underground powerlines. These powerline burials are combined with major roadway reconstruction along with the upgrading of traffic signal battery backup systems to ensure reliability. In the future, to reduce risk to the community, the local planning team hopes to continue to bury powerlines to reduce power grid failures due to tree debris and wind damage. The goal of the local planning team is to limit the duration of an electrical power loss for residents and to provide backup electrical generation to critical facilities during a severe thunderstorm event. Severe Winter Storms Severe winter storms are a regular part of the climate and weather for Waukee. Severe winter storms include blizzards, ice accumulation, heavy snow, and winter storms. These storms can cause power outages during bitterly cold temperatures, road closures, and economic impacts. According to the NCEI, there were 79 winter storm events in Dallas County from 1996 to 2021. These events resulted in $6,613,680 in property damages, with no injuries or deaths reported. Additionally, the USDA Risk Management Agency reported almost $375,000 in crop damages from severe winter storm events from 2000 to 2021. The local planning team reports past occurrences of multiple day winter storms but no structural damage to critical facilities. The top concern identified by the local planning team was the blockage of roads resulting in a reduced ability for emergency services to respond to emergency calls. In an attempt to reduce the amount of power outages due to winter storms, 70% of power lines have been buried. The city plans to convert to a 24-hour snow plowing schedule to keep roadways clear for emergency services during a severe winter storm. The city uses snow fences to reduce the risks associated with winter storms. These fences are located along arterial and collector street corridors where snow drifting onto the adjacent roadway is a known issue. According to the local planning team the snow removal resources are currently sufficient, however staffing is a weak link in the operation. When the city changes to a 24-hour coverage and staff limitations will degrade the timeliness and frequency when a street is cleared and will ultimately decrease the level of service provided for snow removal on public streets. ---PAGE BREAK--- Section Seven: City of Waukee Community Profile Dallas County Hazard Mitigation Plan I 2023 237 Tornado and Windstorm The local planning team identified tornado and windstorm as a top hazard due to their prevalence in the area and potential for damage and loss of life. Windstorms are common across the county and can cause property and tree damage and brief power outages. Tornadoes are much less common, but the impacts can be far greater. Between 1996 and 2021, the NCEI recorded 31 high wind events in Dallas County and three tornados in Waukee. The first brief tornado event occurred in April 2001 with an F0 tornado briefly touching down with no damages, injuries, or deaths reported. Another F0 tornado touched down in fields west of Waukee in May 2004 and resulted in $5,000 of crop damage and $1,000 of property damage, but no injuries or deaths were reported. Finally, in May 2020 an EF0 tornado briefly touched down causing minor damage at a church, a car dealership, and pulling shingles from a house under construction. Roughly $30,000 in property damages were reported. Derechos impacted the community and caused power to be out for five days in August 2020. The local planning team’s top concerns for this hazard including the reliability of the electrical grid. To minimize the effects of tornadoes and windstorms, the city has begun collaborations with MidAmerican Energy Co. to convert overhead powerlines to underground powerlines. These powerline burials are combined with major roadway reconstruction along with the upgrading of traffic signal battery backup systems to ensure reliability. In the future, to reduce risk to the community, the local planning team hopes to continue to bury powerlines to reduce power grid failures due to tree debris and wind damage. The goal of the local planning team is to limit the duration of an electrical power loss for residents and to provide backup electrical generation to critical facilities during a severe thunderstorm event. Transportation Incidents – I-80 Closure This hazard was identified as a top hazard due to the city’s proximity to Interstate 80 that is just over 3 miles south of the city. The interstate experiences closures due to traffic incidents or planned roadway constructions. During these closures, traffic detours through Waukee, a main concern indicated by the local planning team. To help reduce the risk of transportation incidents, the city is collaborating with IDOT and neighboring communities to establish detour routes, install detour signage, and consider coordination of traffic signal operations and timing plans. In the future, the city plans to deploy permanent and portable messaging boards to communicate traffic data to travelers in real time. The creation of a centralized traffic incident management team or facility would further reduce the risk of this hazard. ---PAGE BREAK--- Section Seven: City of Waukee Community Profile 238 Dallas County Hazard Mitigation Plan I 2023 Mitigation Strategy Completed Mitigation and Strategic Actions Mitigation Action Drainage Improvements to Alleviate Flash Flooding near LA Grant and Booth Drive Description Water runoff from adjacent properties causes this area to repetitively flood during periods of intense rain.

These updates are encouraged to occur after every major disaster event, alongside community planning documents annual budgets and Capital Improvement Plans), during the fall before the HMA grant cycle begins, and/or prior to other funding opportunity cycles begin, including CDBG, Water Sustainability Fund, Revolving State Fund, or other identified funding mechanisms. The local planning team is responsible for reviewing and updating this community profile as changes occur or after a major event. The local planning team will include the Fire Chief, Public Works Director, and Police Chief. The plan was reviewed in 2018 and updated to new staff. The plan will be reviewed annually. The public will be included in the review and revision process via city council meetings and city website updates. ---PAGE BREAK--- Section Seven: City of Waukee Community Profile 240 Dallas County Hazard Mitigation Plan I 2023 This Page is Intentionally Blank ---PAGE BREAK--- Section Seven: City of Woodward Community Profile Dallas County Hazard Mitigation Plan I 2023 241 Community Profile City of Woodward Dallas County Hazard Mitigation Plan 2023 ---PAGE BREAK--- Section Seven: City of Woodward Community Profile 242 Dallas County Hazard Mitigation Plan I 2023 Local Planning Team Table WWD.1: Woodward Local Planning Team Name Title Jurisdiction Steven Godwin Council Member City of Woodward Location and Geography The City of Woodward is located in northeast Dallas County and covers an area of 3.65 square miles. Major waterways in the area include Des Moines River, Beaver Creek, and Preston Creek. Demographics Woodward’s population in 2020 was 1,346. The following figure displays the historical population trend from 1890 to 2020. This figure indicates that the population of Woodward gradually increased from 1890 to 1980, leveled off from 1980 to 2000, then saw a sharp drop followed by a sharp increase from 2000 to 2020. Increasing populations are associated with increased hazard mitigation and emergency planning requirements for development. Increasing populations can also contribute to increasing tax revenues, allowing communities to pursue additional mitigation projects. Woodward’s population accounted for 1.4% of Dallas County’s population in 2020.256 Figure WWD.1: Population 1890 - 2020 Source: U.S. Census Bureau 256 United States Census Bureau. “2020 Census Redistricting Data (Public Law 94-171): P1: Race.” 328 550 712 868 901 895 908 967 1,010 1,212 1,197 1,200 1,024 1,346 0 200 400 600 800 1,000 1,200 1,400 1,600 Population Year ---PAGE BREAK--- Section Seven: City of Woodward Community Profile Dallas County Hazard Mitigation Plan I 2023 243 Figure WWD.2: City of Woodward ---PAGE BREAK--- Section Seven: City of Woodward Community Profile Dallas County Hazard Mitigation Plan I 2023 244 The young, elderly, and minority populations may be more vulnerable to certain hazards than other groups.

Woodward’s population has: • 13.6% of people living below the poverty line. The poverty rate in Woodward was higher than the state’s poverty rate (11.1%) in 2020. 261 • $27,214 median household income. Woodward’s median household income in 2020 ($27,214) was about $34,600 lower than the state ($61,836). 262 • 5.4% unemployment rate. In 2020 Woodward had a higher unemployment rate compared to the state (3.9%).263 • 31.2% of workers commuted 30 minutes or more to work. Fewer workers in Woodward commuted 30 minutes or more to work than workers commuting less than 15 minutes (31.2% compared to 42.3%).264 Major Employers Major employers for the city include Woodward Resource Center and Woodward Academy. According to the local planning team, a large percentage of residents commute to other communities for work, such as Perry, Granger, Des Moines, Minburn, and Dawson. Housing The age of housing may indicate which housing units were built prior to the development of state building codes. Vacant housing stock may also be more vulnerable to hazard events if it is poorly maintained. Unoccupied housing may also suggest that future development may be less likely to occur. Communities with a substantial number of mobile homes may be more vulnerable to the impacts of high winds, tornadoes, and severe thunderstorms if those homes are not anchored correctly. Renter-occupied housing depends on the initiative of landlords for proper maintenance and retrofitting to be resilient to disasters. They are less likely than homeowners to have flood insurance, or to know their risks to flooding and other hazards. • 62.4% of housing built prior to 1970. Woodward has a greater share of housing built prior to 1970 than the state (62.4% compared to 50.4%).265 • 2.6% of housing units vacant. Since 2010, Woodward’s vacancy rate decreased. In 2010 the vacancy rate was 8.6%. By 2020, 2.6% of housing units were vacant. 266 267 261 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 262 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 263 United States Census Bureau. “2020 Census Bureau American Community Survey: DP03: Selected Economic Characteristics.” 264 United States Census Bureau. “2020 Census Bureau American Community Survey: S0802: Means of Transportation to Work by Selected Characteristics.” 265 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 266 United States Census Bureau. “2020 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” 267 United States Census Bureau. “2010 Census Bureau American Community Survey: DP04: Selected Housing Characteristics.” ---PAGE BREAK--- Section Seven: City of Woodward Community Profile 246 Dallas County Hazard Mitigation Plan I 2023 • 1.3% mobile and manufactured housing. The City of Woodward had a smaller share of mobile and manufactured housing compared to the state (3.6%).268 • 18.2% renter-occupied. The rental rate of Woodward was 18.2% in 2020. The percentage decreased since 2010, when renter occupied housing was at 23.2%.269 270 Governance A community’s governance indicates the number of boards or offices that may be available to help implement hazard mitigation actions. Woodward has a mayor, a five-member city council, and the following offices. • Clerk/Treasurer • Attorney • Chief of Police • Fire Chief • Public Works Director • Airport Authority Chairperson • City Inspector • Economic Development Director • Library Board Chairperson • GIS/Zoning Administrator Capability Assessment The capability assessment consisted of a Capability Assessment Survey completed by the jurisdiction and a review of local existing policies, regulations, plans, and the programs.

Each applicable planning mechanism is listed below along with a short description of how it is integrated with the hazard mitigation plan. The city will seek out and evaluate any opportunities to integrate the results of the current hazard mitigation plan into other planning mechanisms and updates. Grants and Funding The City of Woodward’s funds are limited to covering maintenance of current facilities and municipal systems only. A large portion of municipal funds are dedicated to the upgrade of current municipal wells. Municipal funds have stayed the same over recent years. The city has applied for and been awarded multiple grants in the las five years. Capital Improvements Plan (2017) The capital improvement plan outlines large purchases and projects that the city would like to pursue. Projects identified in the plan include: storm water projects; upsizing culverts and drainage structures; regular maintenance for drainage structures; upgrading storm sewer systems; regular maintenance for the storm sewer system; and installing emergency generators in critical facilities. The plan does not have a current timeline to be updated. Comprehensive Plan (2017) The comprehensive plan is designed to guide the future actions and growth of the city. The city’s plan contains goals aimed at Safe Growth and identifies areas that need emergency shelters. The city does not have a current timeline to update the plan, but the local planning team has indicated that the next update will limit density in areas adjacent to known hazardous areas, encourage infill development and clustering of development in sensitive areas, and encourage preservation of open space in hazard-prone areas. Building Code (2021) The building code sets standards for constructed buildings and structures. The city has adopted the 2021 International Building Codes. These Codes require the elevation of structures and mechanical systems in the floodplain as well as the installation sewer backflow valves for structures in the floodplain. They also outline proper sump pump installation and require onsite stormwater detention for commercial structures. They allow for raingardens in residential areas, encourage the use of hail resistant building materials, and require hurricane clips during construction. Lastly, the Codes require the use of fire-resistant building materials and the use of defensible space around structures built in the extraterritorial jurisdiction. Zoning Ordinance (2022), Subdivision Regulation (2021) The Zoning Ordinances are continually updated as needed. They prohibit development within the floodplain and limit population density in the floodplain. Community Wildfire Protection Plan (2014) The City of Woodward participated in the Saylorville Flood Plain Community Wildfire Protection Plan (CWPP), which was developed in 2014. The Saylorville floodplain is located along the Des Moines River. The purpose of the CWPP is to help effectively manage wildfires and increase collaboration and communication among organizations who manage fire. The CWPP discusses area-specific historical wildfire occurrences and impacts, identifies areas most at risk from wildfires, discusses protection capabilities, and identifies wildfire mitigation strategies. ---PAGE BREAK--- Section Seven: City of Woodward Community Profile Dallas County Hazard Mitigation Plan I 2023 249 Future Development Trends In the last five years, the Siglin Estates housing development was built in the city. The structure is not located within a floodplain or other hazardous area. In the next five years, the east portion of Woodward will be developed into the Hawks Landing housing development. Community Lifelines Transportation Woodward’s major transportation corridors include State Highway 210 and 2nd Street. The most traveled route is Highway 210, with an average of 3,400 vehicles daily, 126 of which are trucks.271 One of the city’s critical facilities, the water tower, is located along the main transportation route one block east of highway 210. No chemical spills or other significant transportation events have occurred within the city. The nearest airport, Perry Municipal Airport, is located about 12 miles southwest of Woodward. Transportation information is important to hazard mitigation plans because it suggests possible evacuation corridors in the community, as well as areas more at risk of transportation incidents. Hazardous Materials There are gas transmission pipelines that travel near the city and can be seen as blue lines in the figure below.

(See Figure WWD.5) To date, the community has not been able to garner the support to participate in the NFIP due to minimal development anticipated, particularly near the location of the floodplain. However, the city will reevaluate participation if new information becomes available such as interest in development further south of the community. 274 Federal Emergency Management Agency. 2022. “FEMA Flood Map Service Center.” Accessed December 2022. ---PAGE BREAK--- Section Seven: City of Woodward Community Profile 254 Dallas County Hazard Mitigation Plan I 2023 Hazard Prioritization The hazards discussed in detail below were selected by the local planning team from the county hazard list as the relevant hazards for the jurisdiction. The selected hazards were prioritized by the local planning team based on historical hazard occurrences, potential impacts, and the community’s capabilities. For additional discussion regarding area-wide hazards, please see Section Four: Risk Assessment. Severe Thunderstorms (Includes Hail and Lightning) Severe thunderstorms are a regular part of the climate and weather for Woodward. These storms can cause damage through lightning strikes, hail, and high winds. The NCEI reports 14 instances of severe thunderstorms occurring in Woodward from 1998 to 2021. The typical damage seen caused by these severe thunderstorms was toppled trees and power poles or wires due to high winds. These storms caused a total of $80,000 worth of damage across Dallas County. The local planning team reports experiencing Derecho winds in 2020 that resulted in mass damages to houses and property with downed trees and power loss. Additionally, the NCEI reported 16 instances of hail occurring in Woodward. The hail ranged from 0.88 inches to 3 inches that resulted in $106,000 of property damage. The local planning team is highly concerned with severe thunderstorms is acquiring the equipment and manpower required to clean up storm debris. The planning team did not indicate any specific actions or projects implemented to reduce risk and impacts from this hazard. There are no current projects planned for the city to reduce risk of severe thunderstorms either. Tornado and Windstorm The local planning team identified tornado and windstorm as a top hazard due to their prevalence in the area and potential for damage and loss of life. Windstorms are common across the county and can cause property and tree damage and brief power outages. Tornadoes are much less common, but the impacts can be far greater. Between 1996 and 2021, the NCEI recorded 31 high wind events in Dallas County and two tornadoes in Woodward. The brief tornado event occurred in August 1997 with an F0 tornado that reportedly damaged $1,000 worth of crops. The second tornado occurrence was in May 2000 with an F0 tornado that briefly touched down. There were no injuries or other damages were reported. Derechos in 2020 impacted the community and caused power outages, uprooted trees, and damaged structures. The local planning team’s top concerns for this hazard was resulting mass damage to properties. The planning team did not indicate any specific actions or projects implemented to reduce risk and impacts from this hazard. There are no current actions or projects planned for the city to reduce risk of severe thunderstorms either. A resident from Woodward responded to the public survey and indicated that they would like there to be a central place during a disaster where information on repairs and recovery can be found. ---PAGE BREAK--- Section Seven: City of Woodward Community Profile Dallas County Hazard Mitigation Plan I 2023 255 Mitigation Strategy Continued Mitigation and Strategic Actions Mitigation Action Generator Hookup Description Install a transfer switch to enable a portable generator to be hooked up to 3 buildings (Police Station, Fire Station, and City Hall) and potentially any above ground shelter that is built. This will allow power to be restored to continue vital functions and provides continuity of services.

Hazard(s) Tornado and Windstorms Status Warning apps are available and are more reliable for inside warning. Mitigation Action Safe Room/Storm Shelter Description Construct an above ground storm shelter with 200-person capacity as well as retrofitting another structure as an underground shelter. By building a large capacity shelter, the city can accommodate large numbers of people, reducing the potential for loss of life. By retrofitting an inground cement container as a shelter the city can offer multiple venues for protection. Hazard(s) Tornado and Windstorm Status Leadership decision to remove from plan Plan Maintenance Hazard Mitigation Plans should be living documents and updated regularly to reflect changes in hazard events, priorities, and mitigation actions. These updates are encouraged to occur after every major disaster event, alongside community planning documents annual budgets and Capital Improvement Plans), during the fall before the HMA grant cycle begins, and/or prior to other funding opportunity cycles begin, including CDBG, Water Sustainability Fund, Revolving State Fund, or other identified funding mechanisms. The local planning team is responsible for reviewing and updating this community profile as changes occur or after a major event. The local planning team will include the Mayor, City Council Members, and Community Members. The plan will be reviewed annually. The public will be included in the review and revision process via social media updates and the city websites.
