Research notes

Post-2016 Greenbrier flood disaster, WV strengthened floodplain coordination via DHSEM. Federal NFIP mandates minimum standards (44 CFR 60.3) that communities must meet to retain federal flood insurance availability. State model ordinance recommends 2 ft freeboard. This is a federal-state floor, not a state preemption of local zoning per se, but it conditions floodplain district content.
