Sonoma Valley Regional Park Expansion Master Plan

Visit Sonoma Valley Regional Park

Regional Parks is master planning two properties that have been recently added to Sonoma Valley Regional Park. The master planning process is studying the potential outdoor recreation and education opportunities and the restoration and preservation of the sites’ sensitive habitats. Resource studies are being conducted and completed now to inform the Final Draft Master Plan. Two community workshops are being held to gather public input on possible trail alignments and other park amenities. The first workshop took place on October 28, 2015. The second and final meeting is on April 27, 2016. The ‘Become Involved’ tab includes all the details for Community Workshop #2.

The park expansion area includes a 29-acre parcel, known as the Curreri Addition, on its northern boundary and a 41-acre parcel, known as the Sonoma Developmental Center Addition, along Highway 12 and adjacent to the park’s southeast boundary.

The Sonoma Land Trust led the Curreri acquisition with funding from partners, transferring title to Regional Parks in late 2014. The Curreri parcel protects crucial wildlife habitat within the Sonoma Valley Wildlife Corridor and features sweeping views of Sonoma Valley, Sonoma Mountain, and the Mayacamas Mountains.

The Sonoma County Agricultural Preservation and Open Space District purchased the Developmental Center parcel for Regional Parks after the State declared it surplus property. Title was transferred to Regional Parks in 2007. This parcel includes scenic Highway 12 views and also is part of the habitat corridor connecting Sonoma Mountain with the southern Mayacamas Mountains. It offers an opportunity to expand the park’s trail system through iconic oak woodlands.

Become Involved

Sonoma County Regional Parks is seeking community participation for planning of the Expansion Properties at Sonoma Valley Regional Park. Come and learn about the park expansion properties and participate and contribute to the planning process.

Community Workshop #1

The October 28th workshop encouraged public participation by presenting an overview of the expansion properties and the master plan process. Participants were encouraged to participate by working together in small groups and sharing their interests and concerns. Comments and concerns are being compiled by the master plan team to help develop the plans for the park that will be presented to the public in early spring of 2016. Meeting materials for the first Community Master Plan meeting can be accessed below.

Community Workshop #2

At the April 27 workshop participants received a presentation on the preferred plan. Information was presented to the public that addressed Sonoma Valley Regional Park resources and limitations, specifically with sensitivity to biological resources. The Project Manager discussed the outcome of design requests received at the first public meeting and how those were incorporated into the final trail design. Multiple attendees expressed their appreciation for having their ideas represented in the design. Meeting materials for the second Community Master Plan meeting can be accessed below.
