Hd\:; ,..1 l; 1; r, I F -7. Develop DFIRM's and HAZUS Mapping in Hays County The City of San Marcos would be an ideal candidate to join other communities and agencies such as the Lower Colorado River Authority (LCRA), the Harris County Flood Control District and the Cities of Grand Prairie, Corsican a, and Austin to become a Cooperative Technical Partner (CTP) with FEMA. The primary goal of the CTP program is to develop digital flood insurance rate maps (DFIRM's) to comply with FEMA's Map Modernization Initiative. Federal funding for a five-year effort beginning in FY 2003, has been designated for FEMA's DFIRM and CTP efforts. As documented by the Hays County Map Needs Assessment submitted to FEMA, the current FIRM's within Hays County are out of date, do not meet FEMA's digital mapping criteria, and lack technical data such as base flood elevations and floodway delineations needed to regulate floodplain development. An updated countywide flood insurance study is badly needed to provide current floodplain management information for Hays County and each incorporated community within the county. As a CTP, the City of San Marcos could establish study priorities and assist FEMA with program management for the countywide flood insurance study effort and assist with future maintenance of DFIRM (mapping) and hydrologic and hydraulic computer models. I The new DFIRMs developed as part of the flood insurance study effort will also produce the flood element for HAZUS (Hazards United States - FEMA's National Standard Hazard Methodology and Software) mapping for the Mitigation Action Plans for each community in Hays County. Since the City of San Marcos already has GIS capabilities, they would be the ideal HAZUS technical resource for Hays County and the individual communities to use to conduct annual reviews and update of hazard mitigation plans. The HAZUS products maintained by the City of San Marcos can be updated periodically and be made available to Hays County and each community for annual HAZMAP Plan reviews and for the required five year HAZMAP update. Hays County can capitalize on the ongoing FEMA Travis County and Comal County Flood Insurance Studies and the U.S. Army Corps of Engineers Onion Creek Federal Flood Protection Project and assist FEMA in developing DFIRM's (Digital Flood Insurance Rate Maps) in the Onion Creek and other watershed in Hays County.
