Levee breach transforms Sears Point farmland back into wetlands
Cooled by a stiff breeze off San Pablo Bay, about 300 supporters and partners of the Sonoma Land Trust cheered on Sunday as an excavator’s crane broke through a 140-year-old Sears Point levee, allowing saltwater to flood back over 1,000 acres of reclaimed oat hay fields at the southern tip of Sonoma County.
As the water rushed in, the crowd of government officials and others involved in the decade-old Sears Point Restoration Project threw balls of pickleweed seeds into the mud to aid the wetland’s rebirth.
It is expected to take another 25 to 30 years before the marshland’s vegetation and wildlife comes back completely, but a flock of sandpipers swept in Sunday to investigate the small levee breach, which will be widened to 285 feet.
“Historically, over a quarter of the bay’s estuarine habitat was up here at the north end of the bay,” said Don Brubaker, the National Wildlife Refuge manager for the U.S. Fish and Wildlife Service, one of about two dozen partners in the project. “We’re going to see ducks coming in, and wading birds like herons and egrets ... eventually, salmon could move in here.”
About 1,000 members of the public were expected at a tour of the levee site later Sunday. The morning breach was just the start of the work planned this week by the Sonoma County Land Trust, which plans to lower about a mile of the old levee and cut another 285-foot breach along Tolay Creek.
During the past three years, the Sonoma County Land Trust has excavated a channel for the tidal water to enter the field and used the soil to build a new levee protecting the railroad tracks about a mile to the north, which will become the new northern edge of San Pablo Bay.
Public access to the site is expected in early 2016, once safety measures at a railroad crossing are added.
Sunday’s celebration started at 10:30 a.m. with a festive brunch and a string of speakers from various organizations and government, including Congressman Mike Thompson, D-St. Helena; state Sen. Lois Wolk, D-Solano; Assemblyman Bill Dodd, D-Napa; and Sonoma County Supervisor David Rabbitt.
Officials praised the restoration project’s many benefits, saying it will lessen the impact of rising sea levels, protect against floods, filter runoff pollution and attract wildlife.
“We are putting a big down payment toward our sea-level-rise insurance policy,” said Jared Blumenfeld, the southwest regional administrator for the Environmental Protection Agency.
“I have spent a lot of time trying to make levees bigger and stronger, so this is ironic,” Wolk said. “But what we learned with (Hurricane) Katrina is that when the Mississippi Delta was eliminated, that created more of a problem when the sea rose.”
Sears Point was long coveted by developers as the potential site for a number of projects, including an airport, race track and a 6,000-resident Mediterranean-style village.
In 2003, the Federated Indians of Graton Rancheria announced the purchase of 2,000 acres off Highway 37 for $24 million with the financial backing of Station Casinos, with plans to develop a 1,900-slot casino and 200-room hotel at the site. The tribe promised to keep 1,700 acres in open space and to be good stewards of the land.
But those plans garnered loud protest from government entities, including supervisors in every surrounding county, as well as from a coalition of environmental groups. The Sonoma Land Trust co-authored a white paper outlining environmental issues surrounding the proposed casino site.
