FEMA Maps Put Brazoria County Flood Risk on an Address

The Brazos and San Bernard rivers, Oyster Creek, Bastrop Bayou, and Chocolate Bayou show why flood maps matter here. County records name inland Zones A, AE, AH, and AO. Coastal maps also use Zones V and VE.

These are Special Flood Hazard Areas. They mark land reached by a flood with a 1% chance in any year. FEMA says that event has about a 26% chance of happening at least once in 30 years. That does not mean each house has a 26% chance of flood damage.

Search the exact address in FEMA's Map Service Center and save the map panel. For land outside a city, the county Floodplain Department handles permit questions. For land inside a city, ask that city's floodplain or building office. City and county rules can differ.

Flood coverage is separate from a basic home policy. A lender under federal rules often must require it when a building in a high-risk zone backs the loan. A lender may require it elsewhere too. Ask about past losses, drainage, height records, and insurance choices.
