Any expansion of a nonconforming building or nonconforming use, if permitted by variance, and any expansion of any conditional use shall require, in each case, compliance with this Chapter, including, for example, and not by way of limitation, required open spaces, required planted areas, required buffer areas and required parking spaces.

No permit for the erection of any building or structure shall be issued unless the lot abuts a street giving access to such proposed building or structure. Such street shall be an existing State, County or municipal street or highway; a street shown upon a plat approved by the Land Use Board; or a street on a plat duly filed in the office of the County Recording Officer prior to the passage of this Chapter or any prior ordinance which required prior approval of plats by the governing body or other authorized body. Before any such permit shall be issued, such street shall have been certified to be suitably improved to the satisfaction of the governing body or such suitable improvement shall have been assured by means of a performance guaranty in accordance with standards and specifications for road improvements approved by the governing body, as adequate in respect to the public health, safety and general welfare of the special circumstances of the particular street.
