In all cases, off-street loading spaces shall be provided for a building or a group of buildings so that the length of the required space shall be in accordance with the usual size of truck employed for loading or unloading. Each space shall have a vertical clearance of at least fourteen feet. The required areas shall be exclusive of aisle and maneuvering space. (Initiative Ord. Voted 11-8-60.)
