Health & Saf. Code, § 34178

(a) Commencing on the operative date of this part, agreements, contracts, or arrangements between the city or county, or city and county that created the redevelopment agency and the redevelopment agency are invalid and shall not be binding on the successor agency; provided, however, that a successor entity wishing to enter or reenter into agreements with the city, county, or city and county that formed the redevelopment agency that it is succeeding may do so subject to the restrictions identified in subdivision (c), and upon obtaining the approval of its oversight board.

(b) Notwithstanding subdivision (a), any of the following agreements are not invalid and may bind the successor agency:

(1) A duly authorized written agreement entered into at the time of issuance, but in no event later than December 31, 2010, of indebtedness obligations, and solely for the purpose of securing or repaying those indebtedness obligations.

(2) A written agreement between a redevelopment agency and the city, county, or city and county that created it that provided loans or other startup funds for the redevelopment agency that were entered into within two years of the formation of the redevelopment agency.

(3) A joint exercise of powers agreement in which the redevelopment agency is a member of the joint powers authority. However, upon assignment to the successor agency by operation of the act adding this part, the successor agency’s rights, duties, and performance obligations under that joint exercise of powers agreement shall be limited by the constraints imposed on successor agencies by the act adding this part.

(4) A duly authorized written agreement entered into at the time of issuance, but in no event later than June 27, 2011, of indebtedness obligations solely for the refunding or refinancing of other indebtedness obligations that existed prior to January 1, 2011, and solely for the purpose of securing or repaying the refunded and refinanced indebtedness obligations.

(c) An oversight board shall not approve any agreements between the successor agency and the city, county, or city and county that formed the redevelopment agency that it is succeeding, except for agreements for the limited purposes set forth in subdivision (b) of Section 34177.3. A successor agency shall not enter or reenter into any agreements with the city, county, or city and county that formed the redevelopment agency that it is succeeding, except for agreements for the limited purposes set forth in subdivision (b) of Section 34177.3. A successor agency or an oversight board shall not exercise the powers granted by subdivision (a) to restore funding for any item that was denied or reduced by the department. This subdivision shall apply retroactively to all agreements entered or reentered pursuant to this section on and after June 27, 2012. Any agreement entered or reentered pursuant to this section on and after June 27, 2012, that does not comply with this subdivision is ultra vires and void, and does not create an enforceable obligation. The Legislature finds and declares that this subdivision is necessary to promote the expeditious wind down of redevelopment agency affairs.
