Sonoma County Community Separator Workshops


Sonoma County Community Separator Workshops

Community Separators are lands that function to separate cities and other communities, to contain urban development, and to provide city and community identity by providing visual relief from continuous urbanization. Community Separators were originally designated in the 1989 Sonoma County General Plan with a Scenic Resource designation in the Open Space and Resource Conservation Element. Community Separators are currently designated on the General Plan Open Space maps and do not affect the underlying land use designations or the allowable land uses, which generally have an agricultural or rural land use designation.

Agriculture separator in Santa RosaThe current project consists of the following two concurrent actions. While both actions are starting simultaneously, they may or may not be finalized at the same time.

- Prepare a ballot measure for the November 2016 general election to extend the current requirement for voter-approval of any amendments that increase development intensity or reduce the boundaries of Community Separators designated in the General Plan and apply protections to Community Separators between unincorporated communities; and

- Initiate a general plan amendment process to consider additional areas for Community Separator designation and update the related General Plan policies.  

The Sonoma County Permit and Resource Management Department (PRMD) will hold three informal public workshops to discuss possible changes to the community separator policy.

After the public workshops staff will consider additional input received through our website and other stakeholder outreach and will prepare a draft ballot measure.  The Sonoma County Board of Supervisors will hold a public hearing to place the measure on the November 2016 ballot. Staff will also draft General Plan policies, maps, and overlay zone changes to expand community separators. The Sonoma County Planning Commission will hold at least one public hearing to consider the expanded community separators. After the Planning Commission makes its recommendations, the Sonoma County Board of Supervisors will hold at least one public hearing to consider possible changes to the community separator areas.
