The two preceding maps depict known landslide events and soil types in the Buffalo Trace region using data obtained from the KGS. The only historical damage that could be found in the Buffalo Trace Region as a result of landsliding occurred in Lewis County in May, 2003. A Presidential Disaster Declaration was declared for Lewis County as a result of Tornado, Flooding, and Landslide damage. During this disaster, Lewis County lost 5 homes valued at nearly $180,000 as a result of Landslides.

Landslides can happen at any time. Chances of occurrence increase after a heavy rainfall, snow melt, or construction and mining activities. Data is currently unavailable related to a physical standard by which to compare landslide hazard events. The above maps describe the location and extent of occurrences and problem areas based on public input through the mitigation committees. Lewis and Mason Counties have the highest probability while Robertson and Bracken have the least. However, Bracken County has the most trouble areas and Robertson has the least. With the evidence provided above.In future updates of this plan, data needs to be collected and maintained when feasible to identify the locations of events, as well as the dollar losses associated with these events.Plan Update SummaryDue to the uncommon nature of this type of hazard, the committee felt that the existing information provided in the original plan was sufficient at this time. The National Climatic Data Center, at this point, does not have a database on landslides that can be queried. When a database becomes available from this data source, the mitigation committees would like to see this content added to the mitigation plan. The Kentucky Geological Survey was referenced in updating the plan as well as input from committee meetings. Maps have been updated.7.6 Assessing Vulnerability: Identifying AssetsOverall SummaryThe Buffalo Trace Region is mostly susceptible to the flood hazard. Based on hazard profile data, taken from the grid level risk assessment in the Kentucky Hazard Mitigation Plan, the structures at are located in all counties and within the cities of Augusta, Dover, Maysville, Vanceburg, and Flemingsburg. It is estimated that a total of 10,343 homes are at risk in the region. Structures susceptible to damage from flooding include 17 fire stations, 146 major roads and bridges, 5 wastewater treatment plant, and 19 schools. These structures are considered critical facilities for the region, and structural flood damages for these sites could cost millions of dollars to replace. The Buffalo Trace Region is also susceptible to landslides, tornadoes, severe thunderstorms, and severe winter storms. The Kentucky Geological Survey risk maps for landslides as illustrated in Sections 7.5 of this plan show the vulnerable assets of structures and critical facilities in the landslide risk areas is approximately 1.9 billion dollars. These risk areas are general areas that are identified by the Kentucky Geological survey and are described in the Landslide Hazard profile of this plan. Committee members determined from the landslide profile that the greatest potential for damages is to transportation facilities such as roads and bridges that suffer damages from landslides as a result of heavy rains and flooding. The total transportation risk for the landslide total for the Buffalo Trace Region is 1.2 billion dollars. Throughout the profile and identification assets, committee members determined that everything in each jurisdiction is vulnerable to tornadoes, severe thunderstorms, and severe winter storms. These events cannot be pinpointed a particular area and affect each jurisdiction at any given time. The total potential losses of assets to these events is 4.2 billion dollars total. Though these storms will not damage everything at one time, the potential for great losses exists.As committee members reviewed potential dollar losses, they also reviewed past disaster damage totals as provided by FEMA. At the end of section 7.7, a table is presented on past disaster damages based on Public Assistance categories. Overall, the Buffalo Trace Region in past disasters has had an average of $1,626,020 of damage per county, per disaster. (All disaster types combined.) Committee members also reviewed data and information for determining future vulnerable structure and critical facilities in hazard areas. Committee members determined that the goals, objectives, and actions are geared to reduce the development of future buildings out of hazard areas. Committee members have provided tables throughout the identification section that illustrates the potential growth based on the 2010 Census data. In review of this information, committee members emphasized during the Regional Mitigation Public meeting for plan draft review that the purpose of this plan is to reduce the number of structures and critical facilities built in Hazard areas.The impact of each hazard is identified in each hazard profile in the previous section. The greatest impact on the region is flooding, followed by landslides, followed by tornadoes, severe thunderstorms, and severe winter storms. Impacts on each jurisdiction may be found throughout the hazard profile section of this plan.Identification of AssetsIn addition to the identifying and profiling where hazard events may occur, this section of the plan identifies what can be affected by the different hazard events. Building upon the hazard area maps found in the profile in the previous section, we now map and describe the vulnerability to these hazards in terms, types and numbers of existing and future buildings, infrastructure and critical facilities located in each identified hazard area. The information was collected from a variety of resources including the Kentucky Data CD, the National Climatic Data Center, and the Kentucky Revenue Cabinet (PVA structure information). The information was collected, mapped and summarized by the Buffalo Trace GIS staff and reviewed and analyzed by the county sub-committees for ultimate inclusion in the plan. This section was prepared using the best data available for identifying types and numbers of existing buildings, infrastructure and critical facilities. Buffalo Trace ADD GIS staff used local Property Valuation Administrator (PVA) structure and parcel information that was available as GIS spatial data to identify the types and numbers of structures in each hazard area. This data was provided as a result of data provided from the County PVA offices as a result of the cooperation of the Kentucky Revenue Cabinet and their input in the planning process. This data allowed Buffalo Trace ADD staff to map each residential and commercial structure in relation to the hazard area. The following chart describes the local PVA spatial data that was utilized by the Buffalo Trace staff.LOCAL PVA AVAILABLE GIS DATA FOR JURISDICTIONSStructures in Flood Hazard Area MapsMap Inventory for each JurisdictionJurisdictionPVA Structure PVA Parcel?PointsBoundariesBRACKEN COUNTYYESNO MAPS*City of BrooksvilleYESAvailableCity of AugustaYESfrom PVACity of Germantown?YES?FLEMING COUNTYYES?City of FlemingsburgYES?City of EwingYES?LEWIS COUNTYYES?City of VanceburgYES?City of ConcordYES?MASON COUNTYYES?City of DoverYES?City of MaysvilleYES?City of SardisYES?ROBERTSON COUNTYYES?YESCity of Mt.

The Bracken County PVA office is currently developing this information and will be included in future updates of this plan as it becomes available. However, the Bracken County PVA office queried their local databases to provide information on the type and number of structures in each hazard area. Committee members for each jurisdiction reviewed the following maps to determine the vulnerability in each community. Maps have been created by the Buffalo Trace GIS staff to illustrate the types and numbers of existing buildings in the identified flood and landslide hazard areas. For the other identified hazards, which are found in section throughout this section, committee members were not able to identify specific hazard areas for those hazards. These hazards were tornadoes, severe thunderstorms, severe winter storms, and have been determined by the committees to potentially affect anything within each jurisdiction. These hazards and their occurrence is not limited to any particular area based on past historical events and documentation as provided in the hazard profiles for these hazards. These particular hazards can affect any jurisdiction at any time making every asset of each jurisdiction vulnerable; therefore, the only maps specific to hazard areas created were for the flood and landslide hazard areas.The following table is a map inventory showing the maps that were available to the committees to review regarding the types and numbers of existing buildings in the Hazard area.

The committee utilized these maps to help determine risk and hazard vulnerability to help define where risk is located and what areas need mitigation measures. These maps were derived utilizing the Commonwealth of Kentucky Enhanced Hazard Mitigation Plan’s Vulnerability Assessment Model which utilized the following sources: NCDC, Sheldus, FEMA, Kentucky Geological Survey, NOAA. The first four maps address Hazard Identification, Exposure and Vulnerability. Hazard Identification: Anything which either threatens the residents of a community or the things that they valueExposure: A community’s assets: people, property, essential facilities, and infrastructure potentially exposed to a hazardVulnerability: What part of an “exposure” is at “risk” to each ................
