Existing law, the Planning and Zoning Law, among other things, requires the legislative body of each county and city to adopt a comprehensive, long-term general plan for the physical development of the county or city and of any land outside its boundaries that relates to its planning, and provides for the adoption and administration of zoning laws, ordinances, rules, and regulations by counties and cities. Existing law, the Subdivision Map Act, within the Planning and Zoning Law, generally requires local agencies to control and regulate the subdivision of parcels of real property.
