In the event the City of Scranton accepts dedication of the
facilities constructed in accordance with this Part 3, as a condition
of City of Scranton acceptance of said facilities, the applicant shall
provide 15% of the cost of improvements, in the form of a maintenance
bond, as estimated by the applicant's qualified professional, and
approved by the City of Scranton, to cover contingency maintenance
costs for 18 months from the date of stormwater management facilities
acceptance of dedication. The 15% bond shall be based on the construction
costs of the detention basin and outlet structure within the area
dedicated to the City of Scranton. Also, the City of Scranton may
require the developer to make a lump-sum payment to defer future maintenance
costs. Said payment amount shall be negotiated and deposited in a
special City account for maintenance costs of the dedicated facility
only.
