Hinds County, MS Environmental Rules: Flood Zones (2026)

Article XIX, Section 1900 creates the FP District to cover land FEMA has mapped as subject to periodic flooding under the National Flood Insurance Program. ) already applies to the parcel, and its floodplain rules supplement rather than replace that district's regulations. The ordinance is blunt about the floodway itself: no structures of any kind are permitted within an area designated as floodway. Outside the floodway but still within the mapped special flood hazard area, Section 1901 permits only a short list of non-intensive uses, each carrying its own condition: farms and farming (but no permanent dwelling, and no commercial livestock feeding or fattening operations), temporary buildings incidental to farming, seasonal (not permanent) cabins or camps sited more than 100 feet from any street or road and more than 200 feet from any dwelling district, public parks and recreational facilities, temporary accessory buildings, and signs and roadside stands where the underlying district already allows them.

Section 1902 flatly prohibits any use designed for permanent residential habitation in the district, subject only to the Section 1901 exceptions. Public and quasi-public facilities and utilities can be added only as a Section 2406 conditional use, approved by the Board of Supervisors. Anyone developing in the FP District must also separately satisfy the Hinds County Amended Flood Damage Prevention Ordinance, adopted March 9, 1987 and amended since. Dimensional limits for permitted cabins and camps are set in Section 1904: cabins need at least a 1-acre lot, camps at least 5 acres, and buildings top out at 35 feet or two stories unless the Board approves greater height through Site Plan Review under Section 2408.
