(A) The Commission, in granting the conditional use permit, may establish such conditions as it deems necessary and reasonable to protect the best interests of the surrounding property or neighborhood, and the general plan or intent thereof.
(B) Failure on the part of the applicant to complete the required improvements within six months of the granting of the conditional use permit shall render the approval null and void and of no effect; provided, however, that the Commission may with due cause extend such time for an additional period of six months upon written request of the applicant.
