The Planning Commission may, in specific cases involving a subdivision,
land development or mobile home park plan, recommend modifications
from the provisions of these regulations, subject to approval by the
Board of Supervisors that will not be contrary to the public interest
or the spirit and intent of this chapter. Modifications shall only
be granted where, owing to special conditions in a specific subdivision
or plan, the literal interpretation and strict application of the
provisions of these regulations would cause unfair and unnecessary
hardship.
