If such a private road connection is required, the applicant shall construct the private road to the adjacent property line at the time the remainder of the private road within the PUD is built; provided, however, that the PUD ordinance may provide that, as a condition of deferring the construction of the private road connection, the applicant shall prepare and record a restrictive covenant whereby the applicant shall be required to construct the private road connection at such time as the Township requires the same, on the basis of pending or potential development of the adjacent property. The restrictive covenant shall be subject to the approval of the Township Attorney prior to recording and it shall run with the land so as to obligate all subsequent property owners, including a condominium association, if any.
