Bellaire, TX Environmental Rules: Flood Zones (2026)

Bellaire's flood risk is among the highest in the Houston metropolitan area due to its location along Brays Bayou, which bisects the city. Substantial portions of Bellaire fall within FEMA-designated Special Flood Hazard Areas (100-year floodplain, Zone AE). Chapter 50 of the Code of Ordinances implements the National Flood Insurance Program and establishes development standards that exceed FEMA minimums. New residential construction must have the lowest floor elevated to or above the base flood elevation (BFE) plus any freeboard required by the city. Substantial improvements (exceeding 50% of the structure's pre-improvement market value) must be brought into compliance with current flood elevation standards. No development, fill, or obstruction is permitted within the regulatory floodway without an engineering analysis demonstrating no rise in flood levels. The city administers floodplain development permits through the building department. Flood insurance is mandatory for properties with federally backed mortgages in Special Flood Hazard Areas. Bellaire participates in the NFIP Community Rating System (CRS), which provides flood insurance premium discounts for residents. Real estate sellers must disclose flood zone status under Texas Property Code. The Harris County Flood Control District manages Brays Bayou channel improvements that affect Bellaire's flood risk.
