Coastal Zone Boundary

Louisiana's Coastal Zone Inland boundary was modified in the 2012 Regular Session of the Louisiana Legislature with the passage of House Bill 656 (Act 588); those changes become effective on June 7, 2012 upon signature by the Governor. The boundary changes are based on the recommendations of a science-based study conducted for and approved by the Coastal Protection and Restoration Authority, in response to Senate Concurrent Resolution 60 of the 2009 Legislative Session that was submitted to the Legislature for consideration.

The boundary changes affect 10 of the 20 existing coastal parishes. No new parishes were added and no parishes previously in the coastal zone were removed as part of this legislative change. The Louisiana Coastal Zone now includes additional area in eight parishes (Calcasieu, Cameron, Iberia, St. Mary, St. Martin, Assumption, Terrebonne and Lafourche); the Coastal Zone area was reduced in 2 parishes (Livingston and Tangipahoa); and no changes were made in the Coastal Zone boundaries of the remaining 10 parishes.
