Research notes
EGLE designates HREAs along Great Lakes shoreline counties (Berrien, Van Buren, Allegan, Ottawa, Muskegon, Oceana, Mason, Manistee, Benzie, Leelanau, Grand Traverse, Antrim, Charlevoix, Emmet, Cheboygan, Presque Isle, Alpena, Alcona, Iosco, Arenac, Bay, Tuscola, Huron, Sanilac, St. Clair, Macomb, Wayne, Monroe, plus UP shoreline counties). Federal conflict check enabled because Great Lakes shoreline jurisdiction intersects the NOAA Coastal Zone Management Act Michigan program.
