What is Floodplain Management? 

Forty years ago, the Parish adopted floodplain management regulations to reduce future flood damages. Since the Parish became a participant in the National Flood Insurance Program, citizens have the availability to purchase flood insurance and receive federal funds when a disaster strikes (hurricane, flooding, tornado). In return, the Parish must regulate development within the Parish when property is located in a high risk zone. Forty-six percent (46%) of Calcasieu Parish is located in a high risk flood hazard area. 

Calcasieu Parish took one step further and became a participant in the Community Rating System (equivalent to fire rating) which gives the citizens a discount on their flood insurance premium. We save citizens approximately $350,000 each year due to our participation in the Community Rating System.

Calcasieu Parish has a Class 8 rating which saves its citizens 10% on flood insurance policies.

All properties are located in a flood zone.  The difference is, "Are you in a low risk zone or a high risk zone?"

The 1978 Louisiana State and Local Coastal Resources Management Act authorized the development of our local Coastal Management Program. As Calcasieu Parish receives federal and state approval the Parish becomes the permitting authority for coastal uses of local concern. These are defined as “those uses which directly and significantly affect coastal waters and are in the need of coastal management but are not uses of state concern and which should be regulated primarily at the local level if the local government has an approved program.” (R.S. 49:214.25.A.2).

The main function of Coastal Zone Management is the regulation of uses or developments in the “Coastal Zone.” Calcasieu Parish’s coastal zone is located along the Intracoastal Waterway from the Deatonville area to the Calcasieu Locks down to the Ellender Bridge west to the Parish line.


The purpose of the Coastal Use Permit is to make certain that any proposed activity (eg. dredging, bulkheads, etc…) in the Coastal Zone is performed in accordance with guidelines established in the Louisiana Coastal Resources Program. The guidelines are designed so that development in the zone can be accomplished with the least amount of damage to our coastlines.
