California Code, Government Code - GOV § 66499.8

In all cases where the performance of the obligation for which the security is required is subject to the approval of another agency, the local agency shall not release the security until the obligation is performed to the satisfaction of such other agency. Such agency shall have two months after completion of the performance of the obligation to register its satisfaction or dissatisfaction. If at the end of that period it has not registered its satisfaction or dissatisfaction, it shall be conclusively deemed that the performance of the obligation was done to its satisfaction.
