Cal. Gov. Code § 51256.1

No agreement entered into pursuant to Section 51256 shall take effect until it is approved by the Secretary of Resources. The secretary may approve the agreement if he or she finds that the findings of the board or council, as required by Sections 51256 and 51282, are supported by substantial evidence, and that the proposed agricultural conservation easement is consistent with the eligibility criteria set forth in Section 10251 of the Public Resources Code and will make a beneficial contribution to the conservation of agricultural land in its area. The secretary shall not approve the agreement if an agricultural conservation easement has been purchased with funds from the Agricultural Land Stewardship Program Fund, established pursuant to Section 10230 of the Public Resources Code, on the same land proposed to be placed under an agricultural conservation easement pursuant to this section.
