The estuary of Tolay Creek southeast of Petaluma offers refuge to a host of wildlife, including rare shorebirds and waterfowl and a species of endangered mouse that lives only in the salt marshes of San Francisco Bay.
But the tidal waterway, which widens as it drains into San Pablo Bay just south of where it crosses under Highway 37, also sits in the way of a key link in the 500-mile trail envisioned to one day circle San Francisco Bay. About 70 percent of the network is complete.
To span the creek and close the 0.8-mile gap between two existing trails, parks officials are proposing a foot and bike path with a hefty projected price tag: $9 million to $14 million, depending on the design and alignment.
“It’s not a cheap endeavor,” said Ken Tam, planner with Sonoma County Regional Parks. “Where the trail alignment is located is actually in mud flats, and the materials to support a pier structure have to go very, very deep in the bedding to be sound. That increases the overall cost of the construction.”
The money could come from an proposed ballot measure in June that would increase in tolls on state-owned bridges in the Bay Area by $1 to raise an estimated $4.45 billion for transportation upgrades in the region. Up to $100 million could go to a long-delayed overhaul of Highway 37, where rebuilding costs are estimated at $1 billion to $4 billion.
The proposed Sears Point trail connector was endorsed as a parks priority last month by the Sonoma County Board of Supervisors after an initial study highlighting the recreational demand and obstacles associated with the project.
