Research notes
Kentucky regulates stream construction at the state level under KRS 151.250 — independent of and additive to federal CWA §404 USACE permitting and FEMA NFIP. Ohio River floodplain communities (Louisville, Newport, Covington, Paducah, Owensboro, Henderson, Ashland) are the dominant exposure. Locally adopted floodplain ordinances must meet or exceed state and federal floors. KDOW review window typically 60–90 days.
