Special exception uses. Applications for special exceptions,
when listed as authorized uses by the district regulations, shall
be approved or denied by the Zoning Hearing Board in accordance with
the standards and criteria of this article, and the zoning district
regulations, and other applicable provisions of this chapter.
The approval of a special exception application shall be valid
for a period of 12 months from the date of approval. If within this
period the building permit has not been applied for and construction/development
begun, then the special exception approval shall be revoked and the
applicant must reapply for approval. One extension of up to six months
may be granted by the approving body where the applicant can show
good cause for the delay.
