Sonoma Valley Trail (Proposed)
The first phase is to study the feasibility of developing a 13-mile paved trail that generally follows the Highway 12 corridor from the Springs area northwest of Sonoma to the Santa Rosa city limits. The project is an extension of the Central Sonoma Valley Trail and is in the unincorporated area of Sonoma County’s Supervisorial District 1. The trail would provide recreation and commuting opportunities for residents and visitors in Sonoma, the Springs area, Glen Ellen, Kenwood, and Santa Rosa. It would also provide a link to Sonoma Valley businesses, wineries, schools, and parks and to other existing and proposed trails such as the Central Sonoma Valley Trail, Sonoma Schellville Trail, Bay, San Francisco Bay Area Ridge Trail, and Sonoma City trails.
The study area includes the greater Highway 12 corridor from Melita Road at the Santa Rosa city limits to Agua Caliente Road in the Springs area. With community input, the study will identify feasible trail alignments. The proposed paved trail will be 8 feet wide.
Project Cost & Funding Sources
The California Department of Transportation (Caltrans) in September, 2013 awarded a $190,575 Community-Based Transportation Planning grant to launch the feasibility study. The County will contribute a local match of $21,175 for a total of $211,750.
The Sonoma Valley Trail is identified as a project in the adopted 2010 County Bicycle and Pedestrian Plan. Highway 12 is the only transportation arterial connecting Sonoma to Santa Rosa, the largest city in the county. The corridor is a tourism destination, with wineries, regional and state parks, and historical places of interest. The corridor connects commercial areas to urban and rural residential areas with expanses of open space and agricultural land between communities. However, the corridor lacks a separated pathway for pedestrians and bicyclists traveling north and south. This trail project would develop a separated pathway connecting Sonoma with Santa Rosa.
The initial step is to complete a feasibility study. The exact location of the proposed trail is unknown at this time. The study is needed to determine the most feasible route and identify alternatives. The study will include community outreach, evaluation of existing site conditions and roads, mapping, and a preliminary title search. Public workshops will be conducted to solicit input. Furthermore, the feasibility study will help the county develop a project budget that includes estimated costs for design and engineering, construction, environmental mitigation, and property acquisition.
