Project Description

The Houma Navigation Canal ("HNC") Lock Complex ("Project"), is contained in the Louisiana Coastal Master Plan and 2021 Annual Plan (Project TE-113) as a hydrologic restoration project and is needed to reduce saltwater intrusion and distribute freshwater within the Terrebonne Basin, an area which is experiencing one of the highest rates of land loss in coastal Louisiana. Accordingly, this project will help limit the intrusion of salt water into freshwater marsh systems allowing for the maintenance of thousands of acres of wetlands which serve as critical wildlife habitat and nurseries for fisheries. The Project will also provide crucial flood protection by blocking storm surge as a key component of the Morganza to the Gulf Hurricane Protection Project. Implementation of the Project consists of three construction phases. This grant is requesting funding for Phase 1 which consists of Civil site work. During this phase, approximately 95% of the dredging for the Project will be completed. This amounts to approximately 1.2M CY of earthen materials that will be hydraulically excavated in order to construct the project which will be used to re-establish approximately 178 acres of brackish marsh habitat. Work will include placement of fill for the East Levee Tie-in (270 linear feet) and the West Levee Tie-in (345 linear feet) as well as placement of fill and wick drains for the Operations Area. The Shoreline Protection and Access Roads will also be completed during this phase.
