If it is determined that further site review is necessary, the Board of Supervisors shall decide whether to approve or deny the proposed amendment on the basis of such site review. The zoning fees established under Articles XXX and XXII shall apply in such cases.
B. 
If it is determined that the proposed amendment is not of sufficient scope to warrant further site review, the Board of Supervisors shall decide on the basis of the application and supporting documents whether to approve or deny the proposed amendment.

A building may be erected on any lot in the SU-1 Special Use District held in single and separate ownership on the effective date of the ordinance establishing this SU-1 Special Use District where such lot is not of the required minimum area or frontage or is of such unusual dimensions that the owner cannot reasonably provide the open spaces required by the provisions of this article, provided that such erection is approved by the Board of Supervisors after consideration of the factors set forth in § 172-89.
