the approval for any specific SWM site plan. Terms of validity shall
commence on the date the Borough signs the approval for a SWM site
plan. If stormwater management facilities included in the approved
SWM site plan have not been constructed, or if a record drawing of
these facilities has not been approved within this time, then the
Borough may consider the SWM site plan disapproved and may revoke
any and all permits or approvals.
