Research notes
Concurrent regime — local zoning still applies, but a state CUP is an additional required gate. Coastal Zone covers all/part of 20+ parishes (Cameron, Vermilion, Iberia, St. Mary, Terrebonne, Lafourche, Jefferson, Orleans, St. Bernard, Plaquemines, Calcasieu, St. Charles, St. John the Baptist, St. Tammany, Tangipahoa, Livingston, Ascension, Assumption, Iberville, St. James, East/West Baton Rouge, Pointe Coupee). Federal conflict check enabled — paired with the federal Coastal Zone Management Act (CZMA) consistency review and §404 Clean Water Act wetlands permitting. Administered by LDENR Office of Coastal Management (formerly DNR/OCM; reorganized 2023–2024).
