Maintenance by Township. The Township is authorized, where it is
deemed necessary for the public welfare, to enter into contracts with
persons, whereby such persons will dedicate stormwater management
facilities to the Township which will thereafter be responsible for
the maintenance of such facilities; however, before any stormwater
management facilities are dedicated to and accepted by the Township,
such person shall deposit a sum of money with the Township sufficient,
in the opinion of the Township, to provide for the future maintenance
and repair of the stormwater management facilities so dedicated and
accepted.
