Habitat restoration is not only integral to recovery of endangered wildlife—it can also effectively address flood management, water quality, and erosion concerns.
It brings multi-benefit and cost-effective solutions that offset pressure from increased development and associated water resource depletion, habitat degradation, and declining biodiversity.
For more than 40 years, ESA has been collaborating with clients to protect, enhance, and restore natural ecosystems. We have remained at the forefront of the ecosystem restoration practice by providing an integrated, multi-discipline approach that is grounded in a deep understanding of ecology and geomorphology.
Our restoration team offers diverse services, from advancing restoration science to overseeing in-the-ground restoration, and everything in between. Our expertise extends from initial feasibility, planning, and conceptual design, through environmental compliance documentation, permitting, preparation of design drawings and specifications, construction observation, and post-project monitoring.
We view restoration from a “watershed” perspective that accounts for the connectivity and interdependence of hydrology, geomorphology, habitats, and living resources. We recognize the concerns of local communities, and we strive to develop design solutions that incorporate natural and human benefits, including sustainable water supply, flood and erosion protection, water quality improvement, habitat restoration, and recreation.
Using this approach, we have successfully planned, permitted, designed, constructed, and monitored numerous projects throughout the West Coast and Gulf Coast. We bring specialized expertise in a full range of native habitats from headwaters to coast.

Located on the Delta’s western edge in Contra Costa County, just east of Oakley, the Dutch Slough Marsh Restoration is more than a typical wetlands restoration project—it’s a first-of-its-kind experiment that is on track to shape and inform the future of estuarine restoration projects throughout the Delta.
Each month, fluvial geomorphologist Jason White will check in on one of the many restoration projects that ESA has designed and delivered. We are kicking this series off with a visit to a successful project in Trinity County, California: West Weaver Creek. See how this restoration is performing four years after construction.
This restoration project seemed fairly straightforward at first blush: grade the pits, plant native species, and restore the freshwater wetland and upland communities back to the way they were before the area was mined. Then Tom reviewed a historic aerial of the site. “There was a creek there that was breached by the mining activities, which resulted in the creek being cut off from the natural flow patterns in the region,” Tom Ries explains. “As soon as I saw that, I thought, ‘well, we have to restore that creek.’”

According to the U.S. Fish and Wildlife Service, more than half of America’s historic wetlands have been lost or disturbed as a result of human intervention. In San Francisco Bay, this number is even higher, at more than 90 percent.
