All exterior off-street loading areas and services areas (e.g. equipment cleaning areas and delivery truck areas) shall be located, oriented, and designed to reduce the adverse visual and acoustic impacts of their use on adjacent streets, sidewalks, and properties to the maximum extent practicable.
