Cal. Health & Safety Code § 33350.5

After publication of notice of agency public hearing and prior to approval of the redevelopment plan by the agency, an agency may exclude land from a project area after receipt of a report and recommendation from the planning commission. Within 30 days after a change is submitted to it for consideration, the planning commission shall submit its report and recommendation to the agency. If the planning commission does not report upon the change within 30 days after its submission by the agency, the planning commission shall be deemed to have waived its report and recommendation concerning the change, and the agency may proceed to exclude the land from the project area without the report and recommendation of the planning commission.
