The Planning Board may waive, for such period
as it may determine, the provision for any such improvements as, in
its judgment, are not necessary to fulfill the express purposes of
these regulations. In the case of each waiver granted, the Planning
Board shall enter upon its records the reasons why the particular
improvement is not necessary, and it shall attach appropriate conditions
or require such guaranties as may be necessary to protect the public
interest.
Where utilities required by the Planning Board
are to be installed by a public utility company, the Planning Board
may require written assurance addressed to the Board from the public
utility company that such installations will be furnished by the company
within a specified period of time and in accordance with the approved
subdivision plat.
