Cal. Health and Safety Code § 33492.72

(a) Prior to incurring any loans, or other indebtedness, except loans or advances from the local agency or the authority, the agency which established the redevelopment project area, or the board, may subordinate to the loans or other indebtedness the amounts required to be paid to all other local agencies pursuant to this section, provided that the agency or the board has approved these subordinations pursuant to this subdivision. (b) At the time the agency or the board requests any other entity receiving tax-increment revenues pursuant to this section to subordinate the amount to be paid to it, the agency or the board seeking permission for subordination, shall provide the affected taxing entity with substantial evidence that sufficient funds will be available to pay both the debt service and the payments required by this section, when due. (c) Within 45 days after receipt of the agency’s or the board’s request, the entities receiving tax-increment revenues pursuant to this section shall approve or disapprove the request for subordination. An entity other than the redevelopment agency or the board may disapprove a request for subordination only if it finds, based upon substantial evidence, that after the agency or the board pays the debt payments, the agency will not have sufficient funds to pay the amounts required to be paid to other entities pursuant to this section. The agency or the board may also disapprove a request for subordination if it finds that subordination would interfere with its ability to issue debt as needed to carry out its responsibilities. If an entity, the agency, or the board does not act within 45 days after receipt of the agency’s request, the request to subordinate shall be deemed approved and shall be final and conclusive.
