Jefferson County is inland but Ohio River floodplain, Beargrass Creek, Floyds Fork, and Mill Creek trigger MSD floodplain permits under LMCO Chapter 158, with 25-foot stream buffers and FEMA NFIP requirements applying to riparian development.
Though Kentucky has no ocean coast, Louisville sits on the Ohio River with extensive floodplain and riparian regulation. LMCO Chapter 158 (Floodplain Management) implements Jefferson County's FEMA NFIP participation. MSD administers floodplain permits for any development within the regulatory 100-year floodplain of the Ohio River, Beargrass Creek (Middle, Muddy, and South Forks), Floyds Fork, Mill Creek, Pond Creek, and Harrods Creek. MSD Design Manual Chapter 9 requires 25-foot minimum stream protection buffers (wider for higher-order streams and Floyds Fork watershed per the Floyds Fork Special District). Wetland fill requires a Section 404 permit from the US Army Corps of Engineers Louisville District plus Kentucky 401 water quality certification from the Energy and Environment Cabinet per KRS 224.70-110. Streambank alteration requires a Kentucky Stream Construction Permit. FEMA-mapped floodway development is effectively prohibited; lowest floor must be 1 foot above base flood elevation in Louisville Metro.
Floodplain construction without MSD permit: stop-work order and fines $250–$2,500 per day under LMCO 158.99. Unpermitted wetland fill: federal civil penalties up to $64,618 per day under Clean Water Act. Stream buffer encroachment: MSD restoration order and removal at owner expense. NFIP noncompliance risks county flood insurance eligibility.
