FEMA flood zone rules in Broken Arrow, OK — also called floodplain regulations or special flood hazard area (SFHA) rules — determine flood insurance requirements and elevation standards for new construction.
Broken Arrow's floodplain ordinance, administered by the city manager, limits development within the 100-year flood plain by requiring a building permit. Floodplains with drainage areas over one square mile are reserved for flood-tolerant uses: parks, playgrounds, golf courses, nature areas, backyards, parking lots, and agriculture. FEMA digital Flood Insurance Rate Maps are maintained by the Public Works Department. New FEMA maps for Tulsa County become effective June 10, 2026.
Broken Arrow participates in the National Flood Insurance Program and enforces floodplain management regulations. Properties in FEMA-designated Special Flood Hazard Areas (100-year floodplain) must meet minimum construction standards. New buildings must be elevated above base flood elevation. Substantial improvements to existing structures trigger elevation requirements. Flood insurance required for federally-backed mortgages in SFHA zones. Fill and grading in floodways prohibited. Broken Arrow may maintain higher standards than FEMA minimums. Flood zone maps available through FEMA Map Service Center and local planning department.
Construction below flood elevation: retroactive compliance required, fines $500 to $5,000. Floodway encroachment: removal order. Failure to maintain flood insurance: lender force-placement at higher cost.
