More than a dozen Marin bayside sites from Sausalito to Novato could get funding to gird against sea-level rise in the coming years due to Bay Area voters’ recent approval of a $12 annual parcel tax.

But word won’t come until January 2018 as officials with the state-created San Francisco Bay Restoration Authority work for the rest of 2016 and 2017 to set up the system to deliver projects in Marin and other counties.

Among the Marin areas that could receive restoration money: Bahia wetlands in Novato, Simmons Slough seasonal wetlands in Novato, Novato Creek Baylands, Bel Marin Keys, Lower Gallinas Creek, Lower Miller Creek/McInnis marsh, Tiscornia marsh in San Rafael, Lower Corte Madera Creek, Madera Bay Park, Aramburu Island in Strawberry, Bothin Marsh in Mill Valley, Richardson Bay, Sausalito Eelgrass Preserve, as well as creek-to-bay trash reduction projects.

“The projects will likely be updated,” said Caitlin Sweeney, director of San Francisco Estuary Partnership and staff member at the new restoration authority. “The measure does specify a certain amount of projects for each county over time.”

Nona Dennis, an official with the Marin Conservation League, said she was excited about the prospects in Marin and throughout the Bay Area.

“We want our share of the funds, of course, but it’s good to see the entire region involved,” she said.

The tax measure approved by voters June 7 will raise $500 million over 20 years to finance work to reduce the impact of sea-level rise, with a goal of 100,000 acres of wetlands restoration. While the actual need is close to $2 billion, restoration backers believe they can use the local tax dollars to leverage additional state and federal grants.

The restoration authority will appoint a financial oversight committee, as the measure requires, and review plans in the coming months and in early 2017. The tax will show up on property tax bills next July, the same month the agency will request proposals for the environmental work. Then in January 2018, projects will start to be funded.

Marin voters gave 73.5 percent approval, outpacing the 70.32 percent Bay Area-wide vote. The measure needed a combined 66.67 percent in all nine Bay Area counties.

A precinct-by-precinct analysis by the California Coastal Conservancy found that, in most cases, the closer a voter lived to the bay’s shoreline the more likely he or she was to vote for Measure AA, and the farther away he or she lived the less likely.

The analysis showed that Marin, San Francisco, Oakland, Peninsula shoreline communities, San Jose and large parts of the Contra Costa shoreline population all supported Measure AA by more than two-thirds.

In inland areas such as northern Napa and Sonoma counties, eastern Contra Costa and most of southern Santa Clara County, a majority voted no.

The highest support came in San Francisco County, with 77.6 percent, followed by Alameda, 75.2 percent; then Marin; San Mateo, 72 percent; and Santa Clara, 70.1 percent. Surprising many political experts, Contra Costa County voters approved of the measure by 65.7 percent. Less support came from Sonoma County, 64.3 percent; Napa County, 59.1 percent; and Solano County, 54.3 percent.

The analysis showed Democrats cast 61 percent of the ballots, and Republicans 18 percent, with decline-to-state voters at 18 percent. “The fact that the entire Bay Area passed it is remarkable,” Dennis said. “It shows a region-wide understanding of the importance of the issue.”
