The General Plan is a comprehensive plan for growth and development in the City of Grass Valley and the surrounding unincorporated area. Together, the City and surrounding unincorporated area are termed the Planning Area. Every county and city in California is required by State law to adopt a general plan (Article 5, Section 65300 et seq. of the Government Code).
A General Plan is often compared to a "constitution" for local development, and serves as the policy basis for all land use decisions.
