Ecosystem Restoration and Mitigation

Numerous regulations including the Clean Water Act and Endangered Species Act drive ecosystem restoration. In recent years, restoration has become integral to addressing flood management, water quality, and erosion concerns.

ESA’s approach to restoration starts with determining the root causes of observed problems, followed by developing solutions that work with natural systems and processes. We blend rigorous scientific analysis with practical engineering solutions. Our proven success is based on knowledge gained from more than four decades of on-the-ground restoration experience. In our experience, the most successful ecosystem-based restoration designs are developed through the collaboration of multidisciplinary teams of ecologists, hydrologists, biologists, geomorphologists, engineers, water quality specialists, landscape architects, and other specialists.

Today, ESA is involved in restoring sites as far north as Alaska and as far south as San Diego, and from the Pacific Coast throughout the Gulf Coast. Our experts pioneered some of the earliest wetland restoration planning efforts and published design guidelines for restoration of tidal wetlands that are now widely used by restoration practitioners throughout the United States. We have led the planning and design of the two largest tidal wetland restoration projects on the Pacific Coast, the former salt ponds located in the tidal floodplain along the Napa River (10,000 acres) and the South San Francisco Bay (15,000 acres). We are developing innovative shoreline adaptation strategies for sea-level rise, mitigating the vulnerability of our beaches, infrastructure, and communities.

ESA completed award-winning estuarine restoration projects in Oregon near Tillamook and Astoria, and we are currently completing enhancement of 1.5 miles of shoreline in Birch Bay in northern Washington. Farther inland, we are designing the restoration of 13 miles of the Napa River and developing plans to restore native salmon to the Columbia and San Joaquin Rivers. Along the Gulf of Mexico, we are working with the Gulf States, counties, parishes, and federal agencies to plan and prioritize coastal restoration projects funded by the RESTORE Act.
