I. Maintenance of improvements. After construction and
approval of improvements, the developer may be responsible for maintenance
of improvements for a period of time that is specified in the developer's
agreement(s). After the expiration of the developer's responsibilities
for installation and maintenance responsibilities, the maintenance
responsibilities for improvements shall be as follows:
(1) For any public utility such as water service, sanitary

development plans. The applicable utility owner and/or Township shall,
however, have the right to maintain, alter or improve these easements
or rights-of-way or amend the approved development plans for these
areas for the limited purposes of the easement.
