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.
