(A) Off-street loading berths may be open to the sky, covered or enclosed in a building. In any instance where a building is constructed or used for loading, it shall be treated as any other major structure and subject to all requirements thereof.
(B) All open off-street loading areas shall be paved with concrete, or improved with a compacted macadam base, and surfaced with an asphaltic surface to adequately provide a durable and dust-free surface which shall be maintained in good condition and free of weeds, dirt, trash and debris; except that:
(1) A gravel surface may be used for a period not exceeding one year after the loading area is opened for use where ground conditions are not immediately suitable for permanent surfacing as specified above; and
(2) A gravel surface in the area of storage or handling may be used permanently in association with industries that handle liquids or chemicals which create a potential hazard if containment should be lost and where absorption into the ground through a loose surface material would eliminate on or alleviate such hazard.
(C) The surface shall be graded and drained in such a manner that there will be no detrimental flow of water onto adjacent properties or public sidewalks.
(D) When lighting facilities are used to illuminate a loading area, they shall be so located, shielded and directed upon the loading area that they do not create glare or reflect onto adjacent properties or interfere with street traffic.
