This week, Measure AA goes to work accelerating Bay marsh restoration – realizing a vision Save The Bay first had more than a decade ago. On April 11, the San Francisco Bay Restoration Authority will vote on how to spend the first tax receipts from the nine-county ballot measure Bay Area voters overwhelmingly approved in June 2016. The first nine recommended project grants would invest $23.5 million to restore tidal marsh habitat for wildlife around the Bay. Many of these projects also will provide trails and other public recreation, and help protect shoreline communities against flooding. Scientists have told us for decades that the Bay needs at least 100,000 acres of restored tidal marsh to be healthy, after development reduced tidal marsh to only 40,000 acres. Many diked salt ponds and hay fields were acquired and protected for restoration over the last 20 years, bringing that goal within reach, and we identified the missing ingredient is sufficient public funding.Recognizing how much local residents love the Bay, Save The Bay and other key stakeholders worked for years to create a way all of us who live here can help invest in a healthier Bay. We convinced the state legislature to create the Restoration Authority, a regional special district that could propose new funding mechanisms for the Bay. Eight years later, the Restoration Authority finally put Measure AA on the ballot, and voters agreed to pay a modest $12 annually for 20 years. To maximize the impact of these funds, this first round of AA grants supports large and smaller restoration projects all around the Bay, including several in economically disadvantaged communities. (see the full list at www.SFBayRestore.org ) One of the most visible recommended projects is Phase 2 of the Ravenswood Pond restoration from East Palo Alto to Menlo Park. Part of the huge South Bay Salt Ponds complex, this project will convert more of the former commercial salt production ponds back into tidal wetlands. Drivers on the Dumbarton Bridge and California highway 84 have seen these huge brown areas for years, and soon that brown will begin turning green. Save The Bay worked to restore other Ravenswood sites in the past, and we will be creating transition zone habitat there with volunteers at the edge of Bedwell Bayfront Park. These grants are a major milestone in the effort to accelerate Bay restoration, but it is only the beginning. The Bay needs more funding to address the serious strain that growth and climate change are having on the Bay and Bay Area communities. There was more demand for the first AA funds than supply; matching funds will be needed from the state and federal governments to create all the wetlands needed. Proposition 68 on the June statewide ballot is the next opportunity to boost resources for the Bay, as it includes another $20 million in matching Measure AA funds. Through Measure AA, Bay Area residents are funding the largest urban climate adaptation effort in the country, using green infrastructure to make our region more sustainable and resilient to the expected impacts from more extreme storms and rising seas. We look forward to watching the progress of this important work in the coming years.
