If no development has occurred to effectuate the plan within five years after approval is granted, the approval shall be voided and the land shall revert to the district regulations in which it is located.
   (B)   An extension of the time limit or modification of the approved development plan may be approved if the Planning Commission and the Board of Zoning Appeals find that such extension or modification is not in conflict with the public interest.
