The South Bay Salt Pond Restoration Project was an ambitious undertaking, representing the largest tidal wetland restoration effort on the West Coast. Spanning an impressive 15,100 acres, the project transformed a network of industrial salt ponds into a rich mosaic of tidal wetlands and other vibrant habitats.
To minimize the project’s footprint and impact on the delicate habitat, the team utilized specialized amphibious excavators to access the site via water rather than land. This innovative approach allowed them to carry out the necessary work, which included lowering 1,500 feet of levee tops and creating 3 strategic breaches, all while preserving the integrity of the surrounding ecosystem.
Despite these complexities, the project was completed on time and under budget, showcasing the dedication and expertise of the team. The result is a revitalized and thriving wetland landscape that not only enhances the local environment but also provides valuable recreational and educational opportunities for the community.
Major Challenges
The biggest challenge to this project was working in such a biodiverse area and being aware and respectful of the endangered Salt Marsh Harvest Mouse (SMHM). Dutra deployed a team of biologists and landscaping professionals to hand clear each area thoroughly before mobilizing our equipment onto the levees where the breaches were to occur. After encountering numerous SMHM nests we notified Ducks Unlimited & USFW and together we created a new plan as to how to complete this project while preserving the SMHM habitat by eliminating 75% of the levee lowering in the original plans ensuring that the SMHM has a home after the levee breaching operation is completed.
Project Highlights
This project required a lot of coordination and communication across multiple stakeholders, especially when the endangered Salt Marsh Harvest Mouse was encountered. Requiring us to pivot and change our approach as to how to complete this project responsibly while being good stewards of the land. Utilizing amphibious excavators helped us limit our footprint on this project while traveling via water to minimize our impact to the habitat. Completed the project on time and under budget.
Project Scope
The project scope consisted of the restoration and reclamation of a portion of the old South Bay Salt Ponds by lowering 1,500′ of levee tops; 3 breaches in strategic locations.
