An extension of the time limit or modification of the approved final development plan may be approved if the Planning Commission finds that such extension or modification is not in conflict with the public interest.
   No zoning amendment passed during the time period granted for the approved final development plan shall in any way affect the terms under which approval of the planned unit development was granted.
