All off-street parking and loading facilities required by this zoning ordinance shall have an impervious pavement, shall be drained, lighted and maintained by the owner, shall include adequate means of ingress and egress and shall be arranged for convenient access and safety of pedestrians and vehicles. Where parking or loading areas abut a city street, there shall be a protecting curb or barrier at least three feet from the street line and parallel thereto and at least five inches high, securely anchored to the ground and extending continuously across the lot except for the necessary openings for drainage and opposite authorized driveways. The number of parking spaces in a parking area shall not be reduced except upon approval by the Board of Zoning Appeals and then only after proof that, by reason of diminution of floor area, seating, number of employees or change in other factors controlling the requirement of a certain number of parking spaces, the proposed reduction is reasonable and consistent with the intent of this zoning ordinance.
