Permits in Norman Flood Zones - Little River, Bishop Creek, Imhoff Creek
Norman has substantial floodplain coverage from the Little River (bisecting central Norman), Bishop Creek (southeast), Brookhaven Creek (north near OU campus), Imhoff Creek (south-central), the Canadian River (western boundary), and Lake Thunderbird outlet flows.
Any development in a FEMA Special Flood Hazard Area requires a Floodplain Development Permit IN ADDITION to the building permit. Norman applies BFE + 1 foot freeboard for habitable space (one foot above the FEMA national minimum) and a strict no-rise standard inside the regulatory floodway.

Area-specific quirks
What makes Norman Flood Zone Areas different
New structures prohibited in regulatory floodway. Substantial Improvement (50% of pre-improvement market value) forces the entire structure to be brought into current floodplain code - typically full elevation. Get written SI determination from Floodplain Administrator BEFORE filing major remodel permits on pre-1981 homes in SFHA.
