FieldOpValueNote
review_typerequirefloodplain_development_permit_requiredCities and counties with mapped SFHA must adopt and administer a floodplain-management ordinance meeting NFIP minimums; development in the regulatory floodplain requires a local floodplain-development permit reviewed against the ordinance and FEMA 44 CFR Part 60.3 criteria.
base_districts[*].lowest_floor_elevation_ftfloor_atBFE_plus_freeboardLocal ordinance (per state model) requires lowest floor of new/substantially improved residential structures at or above Base Flood Elevation; many Kansas cities adopt 1-foot freeboard or higher. Floodway development may not increase BFE per 44 CFR 60.3(d).

Research notes

State enabling statute paired with federal NFIP framework (44 CFR Parts 59-60). Most Kansas cities participate in NFIP; non-participation cuts off federal flood insurance and disaster assistance for property owners. KDAW-DWR is the state coordinating agency; FEMA is the federal regulator. Key Kansas floodplain risks: Kansas River corridor (Topeka, Lawrence, Manhattan); Arkansas River corridor (Wichita); Missouri River (Kansas City KS, Atchison, Leavenworth). Federal conflict check enabled because federal NFIP minimums set the floor on local ordinance content.
