Ridge trail project to begin on Sonoma Mountain

On Feb. 23, the Sonoma County Board of Supervisors, acting as the Board of Directors of the Sonoma County Agricultural Preservation and Open Space District, approved five contracts totaling $391,360 to prepare for the construction of the North Slope Ridge trail on Sonoma Mountain, and to assist the District with other trail development projects.

“Sonoma Mountain now joins the ring of Bay Area summits that provide public access,” said Valerie Brown, First District Supervisor. “State, County and District-protected properties will be linked together by a multi-use trail that allows the community to enjoy 5,500 acres of contiguous open space.”

The agreements include services from Sonoma County Regional Parks Department for construction management of park improvements, the Bay Area Ridge Trail Council (BARTC) for trail planning and construction oversight, and the Conservation Corps North Bay for trail construction and stewardship tasks such as invasive plant control and fire abatement. Additional contracted services include engineering, surveying, and permitting work that must occur prior to construction. Construction is expected to begin early this summer and be substantially completed by late fall.

The proposed multi-use trail will traverse four District-protected properties, totaling approximately 454 acres and a public investment of more than $12 million, the 84-acre Sonoma Mountain Woodlands parcel owned by Regional Parks, and the approximately 1,400-acre Jack London State Historic Park.

The $1.4 million construction project encompasses access road improvements, a parking area, and a 4.25-mile trail that will total approximately nine miles of trail from the proposed trailhead at Jacobs Ranch on Sonoma Mountain to the Hayfields trailhead at Jack London State Historic Park and add to the larger Bay Area Ridge Trail.

“The North Slope Sonoma Mountain Ridge Trail will be a treasured link in the visionary 550-mile Bay Area Ridge Trail,” said Janet McBride, BARTC Executive Director. “We are thrilled that trail construction is poised to begin – this is the happy result of many years of passionate, persistent efforts among many partners.”

The California Coastal Conservancy has supported the preservation of, and access to, Sonoma Mountain by providing a total of $2,385,000 in grant funding for planning, land acquisition, and public access improvements. The Coastal Conservancy was able to release $341,666 of a $575,000 grant frozen by the State to begin the construction.
