Southwest Coastal Louisiana Project<< Back to Key Initiatives


The Southwest Coastal LA Feasibility Study encompasses Cameron, Calcasieu, and Vermilion Parishes in southwest Louisiana.

Issue Addressed

In 2009, the U.S. Army Corps of Engineers (Corps) and the Louisiana Coastal Protection and Restoration Authority (CPRA) initiated an integrated Feasibility Study and Environmental Impact Statement for Southwest Coastal Louisiana (for Calcasieu, Cameron, and VermilionParishes). The integrated feasibility study developed both a National Economic Development(NED) Plan consisting of risk reduction measures and a National Ecosystem Restoration(NER) Plan consisting of ecosystem restoration measures. This feasibility study was completed in 2016. Congress authorized the Southwest Coastal Louisiana Hurricane and Storm Surge Damage Risk Reduction and Ecosystem Restoration Project in the Water Infrastructure Improvements for the Nation Act of 2016 (WIIN Act of 2016). The estimated total cost to implement the feasibility study was $3,391,116,000 (2016 dollars) and consists of nonstructural measures for 3,961 structures (NED plan: $906,091,000) and 49 coastal habitat restoration features: 9 marsh restoration, 5 shoreline protection/stabilization, 35 chenier reforestation (NER plan: $2,485,025,000).

Project Goals

The project includes structures that have a first floor elevation at or below the 202525-year base flood elevation (BFE). Participation in the project is 100% voluntary. Construction of nonstructural efforts will be cost shared between Corps and CPRA(65% Corps, 35% CPRA). Structure owners will not be responsible for the cost to elevate their structure. The project database contains a total of 3,961 preliminarily eligible structures. A map of these structures can be found below. No additional structures will be eligible for participation without additional Congressional authorization.

Project Status

October 2020
Unfortunately, at this time, Federal Construction funds have not been received from Congress. The Project was not funded in the Federal fiscal year 2020 (October 2019-September 2020) nor was it funded in the 2021(October 2020 – September 2021) President’s Budget. The next opportunity to receive Construction funding will be in the fiscal year 2022 President’s Budget (October 2021 – September 2022) which is currently being developed. We are hopeful that the passage of Hurricanes Laura and Delta will bring renewed attention to the South West region and this project. If you have provided the Project team with an application form, we will continue to keep your structure information on file and contact you and update the website once construction funds have been received. Upon receipt of construction funding, plans and specifications for your home elevation will be performed and the home will be ready for elevation.
