Research notes

Critical Dune Areas (CDAs) mapped along eastern Lake Michigan shoreline (Berrien, Van Buren, Allegan, Muskegon, Oceana, Mason, Manistee, Benzie, Leelanau, Charlevoix, Emmet counties) and selected Lake Superior / Lake Huron locations. Local jurisdictions may seek EGLE delegation to administer permits. Per-parcel geographic predicate keyed to EGLE Critical Dune Atlas. Federal conflict check enabled due to NOAA CZMA overlap.
