Full Breakdown

Under the 2026 Franklin Zoning Ordinance, no development or redevelopment activity may begin in a mapped special flood hazard area without a floodplain development permit from the floodplain administrator. New buildings must be elevated or floodproofed above the base flood elevation, and areas within the Floodway Overlay (FWO) must be kept as non-buildable open space. The city adopts FEMA's current Flood Insurance Rate Maps by reference to stay eligible for the National Flood Insurance Program.

Violations & Fines

Building without a floodplain permit or below required elevation is a misdemeanor; each day of violation is a separate offense, plus city costs and expenses.
