California Code, Government Code - GOV § 14556.18

(a) Commission approval of a project application establishes the time schedule, by fiscal year, for implementation of the phases of a project. Project approval shall be deemed rescinded if the lead applicant agency or the agency responsible for carrying out the project does not seek an allocation from the commission and start the first phase of work during the fiscal year scheduled.

(b) If the first phase is not completed as scheduled, so that work on subsequent phases is delayed, the agency responsible for carrying out the project shall report the reasons for failure to complete the project to the commission. The commission may then reconsider the project application, ask for modification of the schedule and any other requirements of the application, and may, at its discretion, extend the time of reconsideration until environmental studies, review, and approval of final environmental documents has been completed.
