In cases where the reasonable and necessary
need for an off-tract improvement or improvements is necessitated
or required by the proposed development application and where no other
property owners receive a special benefit thereby, the applicant may
be required, as a condition of approval, at the applicant's sole expense,
to provide for and construct such improvements as if such were an
on-tract improvement in the manner provided hereafter and otherwise
by law.
In cases where the need for any off-tract improvements
is necessitated by the proposed development application and where
it is determined that properties outside the development will also
be benefited by the improvements, the following criteria shall be
utilized in determining the developer's proportionate share of such
improvements:
A. Water system. An applicant's proportionate share of
water distribution facilities, including the installation, relocation
or replacement of water mains, hydrants, valves and appurtenances
associated therewith, shall be computed as follows:
(1)
The capacity and the design of the water supply
system shall be based upon standards for potable water supply systems
as determined by the State of New Jersey and regulated through the
Department of Environmental Protection. If the system is able to serve
the entire service area, including the proposed development, no improvement
or enlargement cost will be assigned to the developer.
(2)
If the existing system does not have adequate
capacity to accommodate an applicant's needs, the pro rata share shall
be determined as follows:
|
Total cost of enlargement or improvement
|
|
Capacity of enlargement or improvement
|
---|
|
|
=
|
|
---|
|
Developer's cost
|
|
Development- generated gpd accommodated by enlargement
or improvement
|
B. Roadways. For street widening, alignment, channelization
of intersections, construction of barriers, new or improved traffic
signalization, signs, curbs, sidewalks, trees, utility improvements
uncovered elsewhere, the construction or reconstruction of new or
existing streets and other associated streets or traffic improvements,
the applicant's proportionate cost shall be determined as follows:
(1)
The applicant's engineer shall provide the Borough
Engineer with the existing road anticipated peak-hour flows for the
off-tract improvements.
(2)
The applicant shall furnish a plan for the proposed
off-tract improvements, which shall include the estimated peak-hour
traffic generated by the proposed development. The ratio of the peak-hour
traffic generated by the proposed development to the future peak-hour
traffic shall form the basis of the proportionate share. The prorated
share shall be computed as follows:
|
Total cost of the roadway improvement and/or
extension
|
|
Future peak-hour traffic
|
---|
|
|
=
|
|
---|
|
Developer's cost
|
|
Future peak-hour traffic generated by the development
|
(3)
The ratio thus calculated shall be increased
by 10% for contingencies.
C. Drainage improvements. For stormwater and drainage
improvements, including the installation, relocation or replacement
of storm drains, culverts, catch basins, manholes, riprap, improved
drainage ditches, stormwater detention basin facilities and appurtenances
thereto and the relocation or replacement of other storm drainage
facilities or appurtenances associated therewith, the applicant's
proportionate share shall be determined as follows:
(1)
The capacity and design of the drainage system
to accommodate stormwater runoff shall be based on methods described
in Urban Hydrology for Small Watersheds, Technical Release No. 55,
Soil Conservation Service, USDA, June 1986, and shall be computed
by the developer's engineer and approved by the Borough Engineer.
(2)
The capacity of the enlarged, extended or improved
system required for the development and areas outside the developer's
tributary to the drainage system shall be determined by the developer's
engineer, subject to approval by the Borough Engineer. The plans for
the improved system shall be prepared by the developer' engineer and
the estimated cost of the enlarged system calculated by the Borough
Engineer. The prorated share for the proposed improvement shall be
computed as follows:
|
Total enlargement or improvement cost of drainage
facilities
|
|
Total tributary cfs
|
---|
|
|
=
|
|
---|
|
Developer's cost
|
|
Developer's cfs
|
D. Sanitary sewers. In the event that sanitary sewers
are constructed within the Borough, the following guidelines shall
be followed. For collection facilities, including the installation,
relocation or replacement of collector, trunk and inceptor sewers
and the installation, relocation or replacement of other appurtenances
associated therewith, the applicant's proportionate share shall be
computed as follows:
(1)
The capacity and design of the sanitary sewer
system shall be based on Rules and Regulations for the Preparation
and Submission for Sewerage Systems, New Jersey Department of Environmental
Protection.
(2)
Developer's pro rata share.
(a)
The capacity of an existing system to serve
the entire improved sewage area shall be computed. If the system is
able to carry the total developed sewerage area, no improvement or
enlargement cost will be assigned to the developer. If an existing
system does not have adequate capacity for the total developed sewerage
area, the prorated enlargement or improvement share shall be computed
as follows:
|
Total enlargement or improvement cost
|
|
Total tributary gpd
|
---|
|
|
=
|
|
---|
|
Developer's cost
|
|
Developer's gpd
|
(b)
If it is necessary to construct a system in
order to develop a property, the prorated enlargement share to the
developer shall be computed as follows:
|
Total project cost
|
|
Total tributary gpd to new system
|
---|
|
|
=
|
|
---|
|
Developer's cost
|
|
Development tributary gpd
|
(c)
Plans for an improved system or extended system
shall be prepared by the developer's engineer. All work shall be calculated
by the developer and approved by the Borough Engineer.
