FEMA flood zone rules in Milton, WI — also called floodplain regulations or special flood hazard area (SFHA) rules — determine flood insurance requirements and elevation standards for new construction.
Milton (NFIP CID 550026) participates in the National Flood Insurance Program. Floodplain development in Rock County is regulated under Wis. Stat. §87.30 and Wis. Admin. Code NR 116, with the Rock River and tributaries as primary flood sources. Permits required for any development in mapped Special Flood Hazard Areas.
The City of Milton is an NFIP participating community (Community ID 550026, Rock County). Wisconsin Statute §87.30 requires every municipality with mapped floodplain to enact a floodplain zoning ordinance that meets or exceeds the minimum standards of Wis. Admin. Code Ch. NR 116 and 44 CFR 59-72. Development - including grading, filling, structures, culverts, bridges, and roads - within a Special Flood Hazard Area requires a floodplain zoning permit. New residential structures must have the lowest floor elevated at least 2 feet above the regional (100-year) flood elevation per NR 116.13. Substantial improvements (cumulative work ≥ 50% of structure value) trigger full floodplain compliance. The Rock River drainage and Otter Creek are the primary mapped flood sources affecting the Milton area. Flood maps are issued by FEMA; current FIRMs for Rock County communities should be confirmed at the FEMA Map Service Center.
Development without a floodplain permit can trigger stop-work orders, mandatory removal of non-compliant structures, and forfeitures under Wis. Stat. §87.30(2). Non-compliance also jeopardizes the community's NFIP standing and owners' federal flood insurance availability.
