Sonoma Developmental Center Specific Plan

Document Description
The purpose of the SDC Specific Plan is to guide development of the SDC core campus and preserve open space and natural resources on the SDC property. The State of California enacted Government Code Section 14670.10.5 that outlines the State’s goals and objectives for the SDC Specific Plan and disposition of the property. In light of the statewide affordable housing crisis, State law stipulates that the SDC Specific Plan prioritize housing, especially affordable housing and housing for individuals with developmental disabilities, and stipulates that the open space surrounding the core campus be preserved as open space. The State legislation and other background documents pertaining to the project are available at the project website: In December 2019, the State and the County of Sonoma entered into an agreement for the County to prepare a Specific Plan and related Environmental Impact Report that furthers the State’s objectives as outlined in State legislation for the site, undertake technical studies, and provide for community engagement in land use planning. The State legislation for the site does not mandate that the State will accept the outcome of the County-driven process, and requires the State Department of General Services to proceed with actions that best represent the interests of the State. However, should the State dispose of the site to private or other non-State entities, the property will be subject to County regulatory control and the policies established in the Specific Plan. Following the agreement with the State, Permit Sonoma (the County’s planning agency) began public outreach in January 2020. Significant community input has been gathered through community meetings, workshops, and online surveys. The majority of the outreach has been conducted virtually to accommodate participation throughout the COVID-19 pandemic. Information on community input gathered and work completed to date are available at the project website: Community members have also been engaged since 2015 on their vision for the SDC site, with numerous community members providing input over a span of years prior to this Specific Plan process. Community outreach will continue as the Specific Plan is developed and finalized.
