The San Antonio River Authority Floodplain Viewer engages users in an interactive floodplain map, displaying the Federal Emergency Management Agency’s (FEMA) National Flood Hazard Layer (NFHL) data. Together with its many Bexar Regional Watershed Management (BRWM) partners, the San Antonio River Authority performs engineering studies to develop the data used in these digital maps, providing basic information about the floodplains in Bexar, Wilson, Karnes and Goliad counties.
