Upon filing of any appeal proceeding before the applicable Zoning
Hearing Board and during its pendency before the applicable Board,
all land development pursuant to any challenged ordinance, order or
approval of the applicable Zoning Officer or of any agency or body,
and all official action thereunder, shall be stayed unless the applicable
Zoning Officer or any other appropriate agency or body certifies to
the applicable Board facts indicating that such stay would cause imminent
peril to life or lot, in which case the development or official action
shall not be stayed otherwise than by a restraining order, which may
be granted by the applicable Board or by the court having jurisdiction
of zoning appeals, on petition, after notice to the applicable Zoning
Officer or other appropriate agency or body. When an application for
development, preliminary or final, has been duly approved and proceedings
designed to reverse or limit the approval are filed with the applicable
Board by persons other than the applicant, the applicant may petition
the court having jurisdiction of zoning appeals to order such persons
to post bond as a condition to continuing the proceedings before the
applicable Board.
