Harrison County/Cities of Cynthiana and Berry Natural Hazard Mitigation Plan Identifying Hazards The Harrison County area is vulnerable to a wide variety of natural hazards that threaten life and property. These natural hazards include: Earthquakes Flooding / Flash Flooding Karst/Sinkholes Severe Thunderstorms/Lightning/Wind/Hail Tornados Drought Landslides Dam Failure Severe Winter Storms Wildfires The Harrison County Hazard Mitigation Plan Development Team identified these Hazards based on the historical evidence gathered from the Kentucky State Climatology Center, the National Climatic Data Center, FEMA s Hazard Mapping website, and the Kentucky Geological Survey. The appendices contain maps utilized by the county/city HMPDT in identifying and profiling potential hazards for the planning area. Mitigation Strategy The Clark County Hazard Mitigation Plan Development Team was formed to develop a hazard mitigation plan for the county and its jurisdictions. Committee members included elected officials of the county government and each city government (or their designee), disaster and emergency service managers, floodplain managers, disaster relief coordinator city and county fire and police chiefs, health department officials, city engineers, building inspectors, public schools superintendents, community action organizations, senior citizens, non-profit organizations, local business, and others. The committee looked at data regarding each individual hazard gathered and provided by staff of the Bluegrass Area Development District (BGADD). BGADD staff also developed a risk assessment for each individual hazard. Utilizing background hazard information and best available hazard historical data, the committee responded with overall goals and objectives that are needed to reduce or eliminate the potential loss of life and/or property caused by each hazard. Once these goals/objectives are identified, the committee looked at specific measures aimed at fulfilling the goals and objectives. Various methods may be used to identify desirable
hazard mitigation projects such as success stories, consultation with mitigation experts, and suggestions from ADD staff. Ultimately, objectives put into the plan will reflect the needs of each jurisdiction. After inclusion of projects in the plan, review and approval of the overall plan will be required at the local, regional, and state levels in addition to review and acceptance by FEMA. Implementation of any mitigation projects will be dealt with when the necessity arises.
Floods
Flooding/Flash Flooding Mitigation Goals & Objectives The Harrison County Hazard Mitigation Development Team identifies the following goals and objectives for Harrison County as a whole and the Cities of Cynthiana and Berry based upon the risk assessment for the flooding hazard. Goal 1: To alleviate the amount of flooding throughout Harrison County in order to reduce the overall amount of property damage. Objective A: Ensure that vital infrastructure, such as water and wastewater treatment plants are protected. Goal 2: To alleviate the amount of flooding throughout Harrison County in order to reduce the amount of flood related deaths and other types of injuries. Objective A: Encourage Harrison County residents not to construct their homes and businesses in the designated floodplains throughout the county. Objective B: Continue striving to make sure that transportation routes are passable in the event of high water or at a minimum make sure that low lying roadways are clearly marked. Identification and Analysis of Mitigation Measures The Harrison County Hazard Mitigation Plan Development Team, based on the risk assessment for the following hazards and in line with the stated goals and objectives for each hazard, proposes the following projects for said hazard to eliminate loss of life and property: Flood Hazard Proposed/Possible Mitigation Measures, Actions, and/or Projects Actively continue U.S. Corps of Engineer s Flood Study project relating to flooding in Harrison County, related cities as well as Nicholas and Bourbon Counties, which are contiguous with Harrison County. Promote the comprehensive updating of Flood Insurance Rate Maps (FIRM) floodplain maps throughout Harrison County. Continue floodplain buy-out efforts such as those in the Claysville community where warranted and in areas susceptible to flooding in Harrison County.
Continue looking at the possibility of a flood control project in the City of Berry to ensure that city residents will be able to enter and leave the city when flooding of Route 1032 going through the city.

Identification and Analysis of Mitigation Measures The Harrison County Hazard Mitigation Plan Development Team, based on the risk assessment for the following hazards and in line with the stated goals and objectives for each hazard, proposes the following projects for said hazard to eliminate loss of life and property: Tornado Hazard Proposed/Possible Mitigation Measures, Actions, and/or Projects Develop an information campaign to inform the public about what to do in the event of a tornado (e.g. go to the lowest level or center room in your home, leave all mobile homes, etc.) Publish brochures and/or pamphlets about what to do in the event of a tornado or other storm event in order to further educate the public. (Note: this could be an aspect of the information campaign). Ensure that the Emergency Operations Center is adequately staffed and that personnel can respond after a tornado or other severe storm in Harrison County in order to carry out proper response actions as outlined in the Harrison County Emergency Operations Plan. Encourage county residents to purchase weather radios. Evaluate the number of designated recovery shelters throughout the county in order to serve the public in the aftermath of a tornado or severe storm. Evaluate the comprehensive storm siren plan for Harrison County and ensure all are in proper working order. Seek funds for the installation of new storm sirens in the City of Cynthiana, the City of Berry and other needed areas throughout Harrison County. Continue the progress of the early warning notification system such as SkyWarn, City Watch, Reverse 911, or other telecommunications system, in order to give residents an even earlier warning of approaching dangerous storms. Look at other technology for the purposes of early warning notification as well. Encourage builders to utilize truss straps and other construction techniques that would presumably lessen the amount of destruction and flying debris in the event of a tornado or high winds.
Continue to work with FEMA officials and establish prompt, effective lines of communication in the event of a significant storm in the county. Continue educational programs/training seminars (for example the storm storm spotter classes) currently in place designed to educate the residents of Harrison County and the general public about dangerous storms.

Identification and Analysis of Mitigation Measures
The Harrison County and the Cities of Cynthiana and Berry Hazard Mitigation Plan Development Team, based on the risk assessment for the following hazards and in line with the stated goals and objectives for each hazard, proposes the following projects for said hazard to eliminate loss of life and property: Winter Storm Hazard Proposed/Possible Mitigation Measures, Actions, and/or Projects Develop a public information campaign (through the printing of brochures, pamphlets, or booklets) to educate the public about earthquakes in Harrison County, informing them of the dangers and risks associated with severe winter storms. Begin an information campaign in the schools to educate students about the risks and dangers of winter storms. Amend the Comprehensive Plan to encourage the practice of burying residential utility service(s).
Landslides
Landslides Landslides Hazard Proposed/Possible Mitigation Measures, Actions, and/or Projects Ensure that county roadwork crews have the necessary personnel and equipment to respond to county landslides on roadways. Educate the public through an information campaign about the dangers of unstable land and constructing homes and businesses on landslide-prone areas.
Sinkholes/ Karst Geology
Sinkholes/Karst Sinkhole/Karst Hazard Proposed/Possible Mitigation Measures, Actions, and/or Projects Educate the public about the dangers of sinkholes and the problems associated with constructing homes and businesses on unstable land and sinkhole-prone areas, such as those in the western areas of the county. Continue the cooperative effort between the Bluegrass ADD GIS Department and the Kentucky Geological Society in order to adequately map all the sinkholeprone areas in the county, such as those in the western areas of the county. Establish a sinkhole ordinance in the County to restrict construction in sinkholeprone areas. Continue to Educate public of the dangers of Karst and the problems associated with construction on Karst-laden areas.
Dam & Levee Failure
Dam Failure Dam Failure Hazard Proposed/Possible Mitigation Measures, Actions, and/or Projects Establish the progress of dam inspection of the City of Cynthiana and continue to seek funds for the Terry Dam project. Ensure there is proper signage near and on dams to inform residents about the dam. Encourage the proper maintenance of older dams in order to ensure their safety and help prevent their failure.
Severe Drought
Drought Drought Hazard Proposed/Possible Mitigation Measures, Actions, and/or Projects Ensure the county and its municipalities have in place, a necessary backup water supply in the event of a moderate to severe drought. Ensure water pumps stations are in place and are in proper working order at the county s and city s water supply points. Also encourage the installation of backup pump stations in the jurisdiction and ensure compliance with all of KY Division of Water Regulations.
Wildfires
Wildfires Wildfires Hazard Proposed/Possible Mitigation Measures, Actions, and/or Projects Encourage that city and county fire departments have the necessary personnel and resources available to them in order to respond to grass and other wildfires throughout the county. Make an effort to ensure that more rural parts of the county have adequate water supplies in order to fight grass and other wildfires. Continue the education about controlled burnings and encourage county residents to notify officials in the event of controlled burnings. Ensure the identification of county and city locations through the Geographic Information System (GIS). Establish better lines of communication between and among state officials with respect to wildfires. Encourage more cooperation from the state as well as a quicker and a more adequate response in the event of a wildfire in the county. Also, encourage more funding from the state for the purposes of fighting grass and other wildfires. (for example, a per/acre funding mechanism would be a suggestion). Continue to encourage local government officials to establish a No Burn ordinance. Continue to educate the public about ordinances currently in place about burning after hours in the county and its incorporated municipalities. Continue to educate the public about the dangers of forest fires and the proper maintenance of forested lands where residential structures are constructed. Encourage applying for the Kentucky Firewise Mitigation Grant, which enables local units of government and their agencies to obtain funds to study the problem of wildfires and carry out projects that mitigate against wildfires. The Harrison County Hazard Mitigation Planning Committee believes these projects to be in line with our stated goals and objectives with consideration given to feasibility, acceptability, cost effectiveness, and environmental soundness.
Implementation of Mitigation Measures Prioritization will be based on the following: 1.) Critical need, 2.) Availability of funds, and/or 3.) Schedule of project (e.g. 0-2 years, 3-10 years, or 11-20 years). Projects should be, but are not limited to being prioritized based on a cost benefit review, environmental soundness, and/or technical feasibility. Implementation will be done through the cooperation of agencies both within the Cities of Cynthiana and Berry and those that represent Harrison County at large. Funds should be continuously sought out from various sources and resources (human, technical, and logistical) will be used for implementation of these projects, given the decision is made to follow through with construction or implementation. With respect to implementation, projects should be administered by the agency that has applied for the funds needed to complete the desired mitigation task or project. However, Harrison County officials have the authority to establish administration guidelines, timetables, and funding allocations with respect to mitigation project implementation. Implementation efforts are based on project/action plans drafted by the Bluegrass ADD derived from the input of subcommittees and the Harrison County Regional Hazard Mitigation Planning Committee. Multi-Jurisdictional Mitigation Strategy Currently there is no delineation of hazard mitigation projects between Harrison County and its incorporated municipalities of Cynthiana and Berry. All bodies believe in a cooperative effort in setting attainable goals, objectives, and mitigation actions that would lessen the future cost(s) to property and human life in the event of a natural disaster. Every effort will be made to ensure that end. Please refer to the Identification and Analysis of Mitigation Measures section (above) for some proposed projects the county and cities, or their respective agencies could develop and implement if the decision is made to do so. Plan Maintenance Procedures The hazard mitigation plan requires a plan maintenance process. The following sections address how the Harrison County Mitigation Plan will be updated and maintained when necessary. Monitoring, Evaluating, and Updating the Plan In order to provide monitoring, evaluation, and updates to the mitigation plan every five years, it has been decided by the Harrison County Hazard Mitigation Development Team that Harrison County Emergency Management Agency will administer these task(s). Implementation Through Existing Programs Harrison County and its respective municipalities should incorporate mitigation plan goals and objectives, as well as mitigation actions/projects into program currently used programs (e.g. comprehensive plans, transportation plans, emergency response/operations
plans, etc.). This ensures a cooperative venture, with respect to planning, when and if the decision is made to construct or implement a particular mitigation project at a later date. Continued Public Involvement The Harrison County and Bluegrass Regional Hazard Mitigation Planning Committee have set out the following procedures for inclusion of public participation in the mitigation plan maintenance process. When updates are required, whether by five-year cycle or extenuating circumstances, public input will be solicited primarily via a public notice. A committee (to be chosen at a later date) will review public input once it is received by a set deadline. Upon review by the committee, which will include a vote to determine relevance of public comments, public input will be considered on a case-bycase basis.
