St Tammany Parish Government (Neel-Schaffer, Engineering) Slidell Breakwater Restoration Feasibility Study

St. Tammany Parish Government has hired Neel-Schaffer Engineering to conduct a coastal process study for a potentially 6-mile shoreline area of Lake Pontchartrain between the I-10 twin span bridge and Hwy 11. The purpose of this project is to provide future protection from wave energy, wave-induced erosion, and additional habitat for fisheries, as well as coastal resilience for the greater Slidell community.

The area of the study includes:

• Phase 1 – Eden
• Phase 2 – Carr Drive
• Phase 3 – Lakeview Drive

The team is responsible for performing a feasibility study to determine the real and ongoing negative consequences to the immediate shoreline and littoral habitat within the study area, with the goal of developing a set of potential solutions to meet the following objectives:

1. Providing shoreline protection and coastal resilience improvements for the impacted communities.
2. Providing shoreline improvements to combat the erosive effects of storm-enhanced wave action.
3. Protecting existing habitats and providing additional habitats for native flora, fauna, and fishery communities.

Wingate, as a subconsultant to Neel-Schaffer, has been engaged to assist in design efforts by providing three alternative preliminary design recommendations for both Phase 1 – Eden Isles and Phase 2 – Carr Drive. Wingate is responsible for:

• Reviewing and developing figures of known utilities and including relevant information for project plan development.
• Assisting in the development of alternative designs.
• Drafting sections for each of the alternative design plans, with an emphasis on developing access corridors along the breakwater from deeper waterways for barge and marine traffic.
