Part of the General Plan 2045 update that is currently taking place in the City of Sonoma includes consideration of changing land uses. The city’s General Plan dictates what type of land uses are allowed on every parcel of land within the city’s limits. Changes in land use carry with them the potential for big change. The Sebastiani Winery property on 4th Street East, comprising over twenty acres, may be modified, for example, for a mix of housing and commercial uses.
