Measure AA (San Francisco Bay restoration) was a regional parcel tax approved by voters in November 2016 to finance restoration of tidal wetlands, shoreline resilience, and habitat improvement around the San Francisco Bay. The measure established a funding stream administered by a regional body to support projects across multiple counties, linking land use, conservation, and infrastructure priorities. Measure AA emerged from decades of policy development involving federal, state, and local agencies, nonprofit conservation groups, and tribal organizations.
Measure AA built on prior initiatives including the San Francisco Bay Restoration Authority, the San Francisco Bay Conservation and Development Commission, and the San Francisco Bay National Estuarine Research Reserve planning processes. The proposal followed scientific assessments from the San Francisco Estuary Institute, policy recommendations in the San Francisco Bay Subtidal Habitat Goals Report, and restoration strategies promoted by the Golden Gate National Parks Conservancy. Regional adaptation concerns referenced analyses by the United States Geological Survey, the California Natural Resources Agency, and the California State Coastal Conservancy. Legislative and ballot precedents included measures such as the San Francisco Bay Restoration Authority Formation Measure and funding programs like the Proposition 1 (2014) water bond and the State Coastal Conservancy grants program.
The ballot language for Measure AA described a parcel tax to be collected for 20 years, placed on ballots for voters in cities and counties bordering the San Francisco Bay and administered by the San Francisco Bay Restoration Authority Board. Campaign organizations in favor included the Bay Area Council, the Audubon Society of California, the Sierra Club California, and the Save the Bay coalition; opposition and scrutiny came from taxpayer advocacy groups and certain local governments. The measure was aligned with federal priorities such as the National Fish and Wildlife Foundation programs and invoked partnerships with agencies like the United States Environmental Protection Agency and the National Oceanic and Atmospheric Administration.
Measure AA authorized a flat parcel tax—$12 per parcel annually—collected over 20 years to create a predictable revenue stream for tidal wetland restoration, public access projects, and flood risk reduction. Funds were earmarked through allocation formulas adopted by the San Francisco Bay Restoration Authority Board to support competitive grants, capital projects, and regional planning. The mechanism was coordinated with financing tools including grants from the California Department of Fish and Wildlife, bonding authority exercised by regional agencies, and matching funds from philanthropic institutions such as the Richard and Rhoda Goldman Fund and the Wilburforce Foundation.
Primary goals targeted restoration of tidal marsh, enhancement of habitat for species such as the California Ridgway's rail, the Salt Marsh Harvest Mouse, and the Pacific Herring, and increased resilience to sea level rise for communities along the San Pablo Bay, Suisun Bay, San Francisco Bay National Wildlife Refuge Complex, and adjacent shorelines. Projects funded under Measure AA included levee setbacks, sediment augmentation informed by the Bayland Ecosystem Habitat Goals Project, creation of transitional wetlands, and public access trails connected to the San Francisco Bay Trail. Work interfaced with restoration projects at sites managed by the East Bay Regional Park District, the City and County of San Francisco, the Santa Clara Valley Water District, and the Alameda County Flood Control and Water Conservation District.
Supporters encompassed municipal entities such as the City of Oakland, the City of Berkeley, the City of San Jose, environmental nonprofits including The Nature Conservancy, and labor organizations endorsing green jobs. Tribal governments and organizations, including representatives from the Federated Indians of Graton Rancheria and other Bay Area tribal groups, engaged in consultation on cultural resources. Opponents raised concerns about parcel tax regressivity, the effects on small property holders, and governance transparency; critics included fiscally conservative groups and some property rights advocates. Legal and policy stakeholders referenced precedents in California Proposition 218 litigation and county tax administration practices.
Implementation responsibilities were vested in the San Francisco Bay Restoration Authority Board, which included appointed representatives from each participating county and local jurisdictions, along with technical advisory panels of scientists from institutions such as University of California, Berkeley, San Jose State University, and the Point Blue Conservation Science. The board developed grant criteria, environmental review processes under the California Environmental Quality Act, and monitoring requirements coordinated with the San Francisco Estuary Partnership and the San Francisco Bay Joint Venture. Interagency memoranda of understanding guided collaboration with the United States Army Corps of Engineers and state agencies for permitting and engineering assessments.
Since passage, Measure AA revenues have funded priority projects emphasizing tidal marsh restoration, shoreline protection, and public access; outcomes are tracked through adaptive management frameworks and monitoring programs run by the San Francisco Estuary Institute, academic partners, and local restoration practitioners. Success metrics include acres of restored wetland, increased populations of target species monitored by the California Department of Fish and Wildlife, reduced flood exposure in modeled scenarios by the United States Geological Survey, and public access improvements linked to the San Francisco Bay Trail Project. Ongoing evaluation includes coordination with regional climate resilience planning efforts by the Association of Bay Area Governments and funding leverage reports to state and federal partners.
