Flood Insurance & FEMA Maps
FEMA Flood Maps and Travis County Properties
FEMA flood maps show whether your property is in a high-risk flood zone, which affects your mortgage and insurance requirements.
If you are buying or building in Travis County, check FEMA's flood maps. Properties in a Special Flood Hazard Area (100-year floodplain) may require flood insurance if you have a federally backed mortgage. Lenders check this during the loan process.
FEMA flood maps are public and searchable at msc.fema.gov. Note that local flood risk — especially from creeks and streams — can exist even outside mapped flood zones. LCRA's flood storage on Lake Travis helps reduce downstream risk but does not eliminate creek or storm drain flooding in Austin.
