Where the developer fails to substantially complete improvements
shown on an approved final plan within five years of final plan approval,
and where no extension to such five-year period has been granted,
the Borough may require that construction of any improvements not
substantially completed meet such design standards as may have been
adopted by the Borough since the date of final plan approval. Such
revisions shall affect, but shall not necessarily be limited to, street
construction standards, curb and sidewalk requirements and construction
standards, stormwater management facilities, sanitary sewerage provisions,
water supply provisions, and any other element of the design deemed
by the Borough to be related to the health, safety, and welfare of
the future residents of the development or of the general public.
