Floodplain Development Permits & Regulations

Before beginning any type of construction, you must obtain a building permit from the Permitting Office.

Elevation Requirements

All structures within the Parish must be built to at least 1 foot above the base flood elevation (BFE) or +6.0 MSL, whichever is greater. All machinery and equipment which services a building, i.e. air conditioners, heat pumps, home generators, water heaters and electrical boxes must also be elevated and will require an elevation certificate for the permit. Residents building in flood zone areas also need an elevation certificate before beginning any construction.

State Building Code Requirements

All new construction or substantial improvements must be built to the State Uniform Building Code requirements. All buildings must be inspected for compliance with the State Building Codes prior to issuance of a certificate of occupancy. 

Damaged Structures

If a structure is damaged so that the cost of restoration and repairs would equal to or exceed 50% of the market value, the structure is consider substantially damaged and must comply with the Parish floodplain regulations.
