The commission at any time may amend, or repeal and adopt a new form of, all or any part of the San Francisco Bay Plan but such changes shall be consistent with the findings and declarations of policy contained in this title.
Such changes shall be made by resolution of the commission adopted after public hearing on the proposed change, of which adequate descriptive notice shall be given. If the proposed change pertains to a policy or standard contained in the San Francisco Bay Plan, or defines a water-oriented use referred to in Section 66602 or 66605, the resolution adopting the change shall not be voted upon less than 90 days following notice of hearing on the proposed change and shall require the affirmative vote of two-thirds of the commission members. If the proposed change pertains only to a map or diagram contained in the San Francisco Bay Plan, the resolution adopting the change shall not be voted on less than 30 days following notice of hearing on the proposed change, except that changes proposed under Section 66611 shall not be voted on less than 90 days following such notice, and shall, except as provided by Section 66611, require the affirmative vote of the majority of the commission members.
