Texas Water Development Board (TWDB) State 2D Base Level Engineering (BLE) 20210930 BLE_092021 FEMA-FRD Austin, TX Federal Emergency Management Agency https://msc.fema.gov Federal Emergency Management Agency 20210930 The Flood Risk Database (FRD) contains risk information and supporting data used to depict risk data on a project level. The primary risk data developed are the Changes Since Last FIRM, Risk Assessment Results, Areas of Mitigation Interest, and Depth and Annual Chance grids. The FRD is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, new mapping data, where available, and Hazus risk analysis. The Flood Risk Database and any accompanying products (e.g., Flood Risk Report, Flood Risk Map, and the average annualized loss) are published by the Federal Emergency Management Agency (FEMA). The Flood Risk Database and any accompanying products (e.g., Flood Risk Map [FRM] and Flood Risk Report [FRR]) provide local communities with a summary of flood risk that can be used to develop mitigation strategies and actions. The information presented herein will assist local elected officials, floodplain managers, planners, emergency managers, and many other stakeholders in understanding local flood risk so that it can be better communicated to the general public. Data are presented at both the watershed and/or community levels, in narrative, spatial, and tabular formats. Providing risk assessment information at the watershed level emphasizes that flood risk extends beyond community corporate limits and flood risk reduction activities impact areas beyond the immediate site. A project-level FRR and FRM may also be included to highlight areas of relative risk within the watershed, community boundaries in relation to the overall watershed, flooding sources and stream reaches that were newly or re-studied, and the contributing factors to flood losses. 20210930 FIRM and FIS Effective Date Complete Unknown -98.56 -97.39 31.61 30.79 ISO 19115 Topic Category hydrology environment inlandWaters structure transportation elevation boundaries FEMA NFIP Topic Category Flood Risk Database (FRD) Hazus Changes Since Last FIRM CSLF Areas of Mitigation Interest AOMI Flood Risk Report FRR Flood Risk Map FRM None REGION 06 STATE TX HUC8 MISSION HYDROLOGIC UNIT 12100406 COUNTY BEE COUNTY GOLIAD COUNTY KARNES COUNTY REFUGIO COUNTY-FIPS 025 COUNTY-FIPS 175 COUNTY-FIPS 255 COUNTY-FIPS 391 COMMUNITY TOWN OF REFUGIO COMMUNITY TOWN OF WOODSBORO FEMA-CID 480540 FEMA-CID 480987 None The Flood Risk Database (FRD) and any accompanying products (e.g., Flood Risk Report [FRR] and Flood Risk Map [FRM]) are not intended to be the final authoritative source of all flood risk data in a watershed.
