Research notes

Applies to the three coastal counties: Hancock (FIPS 28045), Harrison (28047), Jackson (28059). Administered by Mississippi Department of Marine Resources (MDMR). Parallel regulatory layer over local §17-1 zoning, not a preemption of zoning density. Federal conflict check: federal CWA §404 USACE permit and NOAA Coastal Zone Management Act consistency review may also apply. Companion to §49-15 (CZM) and the Public Trust Tidelands Act (§29-15).
