Full Breakdown
Title 22 of the county code, re-enacted by Ordinance No. 2015-11, governs flood damage prevention. Section 22-3-1 applies the title to all areas of special flood hazard identified by FEMA or by best-available data documenting flood risk within county jurisdiction. Section 22-3-2 adopts FEMA's November 30, 2023 Flood Insurance Rate Maps, Flood Boundary-Floodway Maps, and Digital Flood Insurance Rate Maps by reference, along with any future revisions. Section 22-3-3 then requires a Floodplain Development Permit to ensure conformance with the title before land in a mapped hazard area is developed.
Section 22-3-8 backs this up by barring any structure, recreational vehicle, manufactured home, or land-use change without full compliance, and Section 22-3-9 lets the floodplain administrator issue a written stop-work order any time regulated work proceeds contrary to the title, requiring cited work to cease immediately. A. 5, which let counties regulate flood channels and floodplains within their borders. Where Title 22 conflicts with another ordinance, easement, covenant, or deed restriction, Section 22-3-4 applies whichever standard is more restrictive.

Each day a violation occurs is a separate offense, and the floodplain administrator may also pursue a stop-work order under Section 22-3-9 or any other lawful remedy.
