A transportation permit may be designated by the Director of Public Works as either a single-move transportation permit, for the movement of a vehicle or load over a designated route and for a move on a specified date or dates, or a multiple-load transportation permit, issued for the period specified on the permit but not to exceed six months. Multiple-load transportation permits may be issued on the type of vehicle carrying the load in the case of non-self-propelled vehicles and on the specific vehicle in the case of the self-propelled vehicles. Multiple-load permits shall authorize the movement of the vehicles or loads specified on the permit; provided, however, that the vehicle or load shall not exceed a width of 13 feet, a height of 16 feet, or a length of 100 feet. If the load proposed under the multiple-load transportation permit exceeds the weight limits as prescribed in Division 15 of the Vehicle Code of the state of California by more than 25 percent, said move shall be subject to such route restrictions as designated by the Director of Public Works. (Ord. 1205 § 2, 1969; prior code § 27.213(2)).
