In addition to the limitations set forth in Section 607, franchises, permits, licenses or leases shall be subject to the following:
(a) Maximum Use of Water Frontage.
(1) Board Approval Required. Unless approved by a four-fifths vote of the board and approved by a two-thirds vote of Council, no franchise, permit, license or lease shall be made to any one person, firm or corporation to use in excess of 3,000 feet of the water frontage, linear measurement, measured along United States harbor lines of the Harbor District.
(2) Automatic Termination for Violation. No assignment, transfer, gift, hypothecation, or grant of control of a franchise, permit, license, or lease shall be valid for any purpose unless first approved by the board. Any franchise, permit, license or lease shall be terminated by operation of law if the holder of it attempts to assign, transfer, sublease, give, hypothecate or grant it and the result would be any usage by another person, firm or corporation of more than the 3,000 foot limitation described in subsection (a)(1).
(b) Prohibition on Leasing Harbor Property as Excess. No wharf, dock, pier, mole or transit shed owned or controlled by the City shall ever be leased for non-departmental purposes under Section 605(b).
(c) Revocation Upon Notice. Every assignment of a berth or landing, or of space in any warehouse, elevator or like facility operated by the City, or grant of a revocable permit shall be revocable by the general manager, without compensation to the grantee or lessee, upon notice.
