Converse, TX Environmental Rules: Flood Zones (2026)

Converse participates in the National Flood Insurance Program (NFIP) and enforces floodplain management through its Flood Damage Prevention Ordinance, consistent with 44 CFR Part 60. FEMA Flood Insurance Rate Maps (FIRMs) show Special Flood Hazard Areas (SFHA) including Zone AE and Zone A, primarily along Salatrillo Creek, Cibolo Creek tributaries, and drainage channels. Within SFHAs, any new construction, substantial improvement (over 50 percent of market value), or fill activity requires a floodplain development permit. New residential structures must have the lowest floor elevated at least one foot above the Base Flood Elevation (BFE), commonly known as freeboard. Nonresidential structures may be dry-floodproofed. An Elevation Certificate prepared by a Texas-licensed surveyor is required at completion. Federally-backed mortgages on properties in SFHAs require flood insurance. Verify your property's flood zone using the FEMA Map Service Center and contact Converse Public Works at (210) 658-5356 before buying or building.
