Cal. Health & Saf. Code § 33385.5
The agency shall forward copies of the proposed amendment to the redevelopment plan to the project area committee, if one exists, at least 30 days before the hearing of the legislative body, required in Section 33454.
Where the proposed amendment would enlarge the project area, the redevelopment agency shall call upon the project area committee to expand its membership to include additional members on the project area committee in compliance with Section 33385. Such expansion of membership shall be submitted to the legislative body within 30 days for the body's approval within 60 days to assure that the project area committee is representative. The legislative body shall not hold the public hearing, required by Section 33454, until the enlarged project area committee has had at least 30 days to consider the proposed amendment.
The committee, if it chooses, may prepare a report and recommendations for submission to the legislative body. If the project area committee opposes the adoption of the proposed amendment, the legislative body may only adopt the amendment by a two-thirds vote of its entire membership eligible and qualified to vote on such amendments.
