before the enactment of this chapter but is in violation of this chapter,
provided that construction based on such building permit shall have
been started within the effective period of the permit, but not to
exceed one year from the effective date of this chapter, and, in the
case of a site plan or variance, a building permit shall have been
issued within 90 days following the effective date of this chapter.
In all instances, the project shall be continuously pursued to completion;
otherwise said approvals and permits shall be void.
