Yosemite Slough Wetland Restoration

Restoration of a Contaminated Site at Candlestick Point in San Francisco to Create a Functioning Tidal Wetland and Opportunities for Public Access.


  • Develop a master plan for the park, including restoration and landscape design
  • Remediate contaminated soils and restore vital habitat along San Francisco Bay
  • Provide opportunities for public education and recreation


 Project Description

In 2011, the California State Parks Foundation completed the first phase of the Yosemite Slough restoration, one of the largest tidal wetland restorations in San Francisco Bay.  WRA is currently working on Phase 2 which focuses on implementing capital improvements on the north shoreline.

Eventually the project (with additional construction funding) will restore 34 acres of natural habitat, including 12 acres of tidal wetlands, foraging habitat for shorebirds, and nesting islands for special-status birds while remediating contaminated Bay mud and soil.  The project will also create opportunities for public recreation, including wildlife observation, picnicking, walking, and bicycling.

WRA is the lead design and permitting consultant for the project, working with a dedicated team of planners, environmental scientists, engineers, and contamination specialists on all aspects of the project including initial biological studies environmental impacts analysis, restoration design, development of a master plan for the park, final design and engineering drawings.

The project has involved the full range of services offered by WRA, including ecological surveys conducted by WRA’s biologists, environmental permitting and California Environmental Quality Act (CEQA) analysis prepared by WRA’s environmental planners. Restoration, park design, Bay Trail design, native plantings within the wetland, and upland landscaping were developed by WRA’s landscape architects.  WRA also worked with Noble Consultants to conduct an analysis of the potential effects of future sea level rise. WRA’s oversight of the consultant team and coordination with regulatory agencies including the U.S. Army Corps of Engineers, the Regional Water Quality Control Board, and the Bay Conservation and Development Commission has resulted in successful implementation of the first phase of the project and has laid a strong foundation for the future of this long-term restoration effort.
