Terrebonne Parish, LA Environmental Rules: Boat Dock Permits (2026)

There's no ordinance in the Terrebonne Parish Code that names 'boat docks' specifically. Waterfront construction, including bulkheads and any structure requiring a state or federal wetlands permit, is captured instead by Chapter 12's Coastal Impact Certificate, adopted under Ordinance No. 9663 in October 2024. Section 12-6(a) requires the certificate before performing soil regrading, seismographic survey work, construction of wells or pipelines, dredging of canals or wetlands, and the construction of bulkheads, drainage control structures, flood control structures, landfills, spoil areas, platforms, board roads, levees and battures.

It goes further with catch-all clauses covering construction of single-family residential structures requiring a coastal zone permit from the Louisiana Department of Energy and Natural Resources or a Section 10/404 permit from the Army Corps of Engineers, and, separately, any other structure or facility in the parish requiring one of those same two permits. Because a private dock, pier, or boathouse built over water or wetlands in coastal Terrebonne Parish typically needs a Section 10/404 permit from the Corps, or a state coastal use permit, that construction falls inside this catch-all and triggers the parish certificate requirement.

Section 12-2 makes the chapter apply parish-wide, and section 12-4 directs that its provisions be liberally construed in the parish's favor and read as not limiting any other state-granted powers. 00 for larger commercial or high-acreage work.
