California Code, Government Code - GOV § 51234

Any proposal to establish an agricultural preserve shall be submitted to the planning department of the county or city having jurisdiction over the land. If the county or city has no planning department, a proposal to establish an agricultural preserve shall be submitted to the planning commission. Within 30 days after receiving such a proposal, the planning department or planning commission shall submit a report thereon to the board or council. However, the board or council may extend the time allowed for an additional period not to exceed 30 days.

The report shall include a statement that the preserve is consistent with the general plan, and the board or council shall make a finding to that effect. Final action upon the establishment of an agricultural preserve may not be taken by the board or council until the report required by this section is received from the planning department or planning commission, or until the required 30 days have elapsed and any extension thereof granted by the board or council has elapsed.
