California Code, Health and Safety Code - HSC § 33200

(a) As an alternative to the appointment of five members of the agency, the legislative body may, at the time of the adoption of an ordinance pursuant to Section 33101 or 33140 of this part, or at any time thereafter by adoption of an ordinance, declare itself to be the agency; in which case, all the rights, powers, duties, privileges and immunities, vested by this part in an agency, except as otherwise provided in this article, shall be vested in the legislative body of the community. If a member of the legislative body of a city or county does not wish to serve on the agency, the members may so notify the legislative body of the city or county, and the legislative body of the city or county shall appoint a replacement who is an elector of the city or county to serve out the term of the replaced member.

However, in any community in San Bernardino County which is a charter city, the adoption of any order or resolution by the legislative body acting as the agency shall be governed by the same procedures as are set forth in the provisions of the charter, and the mayor shall be the chairperson of the agency, having the same power and authority in the conduct of the agency and the meetings of the legislative body acting as the agency, that the mayor has in the conduct of the affairs of the city.

As part of the legislative body's ordinance declaring itself to be the redevelopment agency pursuant to this subdivision, the legislative body shall make findings that the action shall serve the public interest and promote the public safety and welfare in an effective manner.

(b) In the event an appointive agency has been designated and has been in existence for at least three years, the legislative body shall not adopt an ordinance declaring itself to be the agency without first conducting a public hearing on the proposed ordinance.

Notice of the public hearing required by this subdivision shall be published not less than once during the 10 calendar days immediately prior to the hearing in a newspaper of general circulation, printed and published in the community, or if there is none, in a newspaper selected by the legislative body. The notice of hearing shall include a general statement of the procedure and effect of the legislative body's declaring itself to be the agency. Copies of the notice shall be posted throughout the affected project area or areas at least 10 calendar days prior to the hearing. The legislative body shall also mail by first-class mail copies of the notice at least 10 calendar days prior to the hearing, to all persons who have expressed to the agency or the legislative body an interest in receiving information on redevelopment activities.

The legislative body shall cause the preparation of any report or reports or proposals, as are necessary to substantiate and explain the determination that the legislative body shall declare itself the redevelopment agency, to be presented at the public hearing.

As part of the legislative body's ordinance declaring itself to be the redevelopment agency pursuant to this subdivision, the legislative body shall make findings that (1) the action will serve the public interest and promote the public safety and welfare in a more effective manner than the current organization, and (2) there has been full public disclosure of all reports and proposals relating to the legislative body's intent to declare itself the redevelopment agency.
