San Francisco Bay Clean Water, Pollution Prevention and Habitat Restoration Measure

The San Francisco Bay Clean Water, Pollution Prevention and Habitat Restoration Measure (Measure AA) is a $12-per-year parcel tax for the San Francisco Bay area of California  which passed with over 70% support in all nine Bay Area counties on June 7, 2016.  The measure is anticipated to generate $500 million over 20 years  approximately $25 million annually for critical tidal marsh restoration projects around San Francisco Bay. Measure AA was the first parcel tax in the history of the state to be levied throughout an entire region encompassing multiple counties. The counties involved include: San Francisco, San Mateo, Santa Clara, Contra Costa, Alameda, Napa, Solano, Sonoma, and Marin County, California.

Projects funded by the tax will be focused on coastal tidal marsh and wetland restoration - in order to provide habitat for fish and wildlife; filter out pollutants and toxins from water and the ecosystem; provide urban recreational open space; and act as a natural barrier against flooding and sea level rise. The revenue will be dispensed by the San Francisco Bay Restoration Authority across the region on an annual basis.

The projects supported by Measure AA are to advance the following programs:

1. Safe, Clean Water and Pollution Prevention Program: The purpose of this program to be funded under the Measure is to remove pollution, trash and harmful toxins from the Bay in order to provide clean water for fish, birds, wildlife, and people.

2. Vital Fish, Bird and Wildlife Habitat Program: to significantly improve wildlife habitat that will support and increase vital populations of fish, birds, and other wildlife in and around the Bay.

3. Integrated Flood Protection Program: to use natural habitats to protect communities along the Bay’s shoreline from the risks of severe coastal flooding caused by storms and high water levels.

4. Shoreline Public Access Program: to enhance the quality of life of Bay Area residents, including those with disabilities, through safer and improved public access, as part of and compatible with wildlife habitat restoration projects in and around the Bay.


Additional funding allocation criteria includes giving priority to economically disadvantaged communities. 

Priority will also be given to projects that meet the selection criteria of the Coastal Conservancy’s San Francisco Bay Area Conservancy Program and are consistent with the San Francisco Bay Conservation and Development Commission’s coastal management program and with the San Francisco Bay Joint Venture’s implementation strategy.


The San Francisco Bay Restoration Authority is a separate government entity established by the California State Legislature through Assembly Bill 2954 in 2008, and formed in 2009. The restoration authority's website describes itself as "a regional government agency charged with raising and allocating resources for the restoration, enhancement, protection, and enjoyment of wetlands and wildlife habitat in the San Francisco Bay and along its shoreline.”
