I I I 2. Assess the Hazard (Risk Assessment -CRS Activity 511.4.) 2.1 Map of Known Hazard Areas. The Hays County Map of Known Hazard Areas is a GIS mapping document included in Attachment "B". Mr. Steve Floyd, Hays County Environmental Health Department, prepared a GIS Base Map for Hays County identifying each community with overlays showing critical facilities cross-referenced with flood hazard mapping and other hazards. The GIS Base Map was utilized by the Hays County Mitigation Planning Committee and the Consultant to analyze hazard impacts on Hays County unincorporated areas and each community within the county. The Hays County Flood Hazard is visually displayed in the series of figures include in Section 2.3, Flood Hazard: Figure 2.1 - Flood Hazard Sector 1 - Dripping Springs Figure 2.1 - Flood Hazard Sector 2 - Ky1e/Buda Figure 2.1 - Flood Hazard Sector 3 - San Marcos Figure 2.1 - Flood Hazard Sector 4 - Wimberley Also, Table 4, "Hays County Existing NFlP Mapping" lists the flood insurance program mapping published by FEMA. Table 4 identifies each map panel, publication date and map scale and lists streams studies, floodway information and remarks. Table 4 also includes a summary of map panels published, panel age, and technical data age and lists the NFIP status of each community in Hays County. 2.2 Known Hazards. Hays County is exposed to many hazards, all of which have the potential to disrupt communities, cause casualties, and damage or destroy property. The Hays County Mitigation Planning Committee conducted a Multi-Hazard Inventory and Risk Assessment for twenty- four (24) Natural Hazards and thirteen (13) Technological Hazards that may impact Hays County. During the May 2003 and June 2003 Hays County Mitigation Planning Committee meetings, Table 2, "Multi-Hazard Inventory and Risk Assessment, Hays County", was prepared listing each hazard and showing the priority level, severity, frequency and Committee Comments. [TxDEM P-34] This information is summarized in Table 3, "Hazard Rating Summary", which identifies the major hazards that Hays County is most likely to face. Additionally, the impacts on public health and safety and the impacts on property are illustrated. The process of identifying hazards is two-fold. First, a hazards analysis is developed. It is a stand-alone product consisting of maps, databases, charts, atlases, and other supporting documentation. The analysis provides a risk-based, quantitative method, to prioritize mitigation and preparedness needs for the jurisdiction as a whole. This analysis will be reviewed and updated annually. The Hays County Multi-Hazard Inventory and Risk Assessment was completed by Halff Associates, Inc. in December 2003 [P-34]. Individual Hazard Worksheets is included in Attachment "D" of this Plan.
