Developers shall be required, as a condition
for approval of a subdivision or site plan, to pay their pro rata
share of the cost of providing reasonable and necessary street improvements
and water, sewerage and drainage facilities and easements therefor
located outside the property limits of the subdivision but necessitated
or required by construction or improvements within said subdivision.
The following criteria shall be utilized in determining a developer's
proportionate or pro rata share of necessary off-tract improvements.
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
provided by law.
In cases where the need for any off-tract improvement
is necessitated by the proposed development application and where
it is determined that properties outside the development will also
be benefited by the improvement, the following criteria shall be utilized
in determining the developer's proportionate share of such improvements:
A. Sanitary sewers. For distribution facilities, including
the installation, relocation or replacement of collector, trunk and
interceptor 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 the design of the sanitary sewer
system shall be based on Rules and Regulations for the Preparation
and Submission of Plans for Sewerage Systems, NJDEP, and all Bridgewater
Township sewer design standards, including infiltration standards,
and all other Bridgewater Township stormwater drain standards.
(2) Developer's pro rata share.
(a)
The capacity of the existing system to service
the entire improved drainage area shall be computed. If the system
is able to carry the total developed drainage basin, no improvement
or enlargement cost will be assigned to the developer. If the existing
system does not have adequate capacity for the total developed drainage
basin, the prorated enlargement or improvement share shall be computed
as follows:
|
Total enlargement or improvement cost
|
|
Total tributary gpd
|
|
|
=
|
|
|
Developer's cost
|
|
Development gpd
|
(b)
If it is necessary to construct a new system
in order to develop the subdivision, 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)
The plans for the improved system or extended
system shall be prepared by developer's engineer. All work shall be
calculated by the developer and approved by the Township Engineer.
B. Roadways. For street widening, alignment, channelization
of intersections, construction of barriers, new or improved traffic
signalization, signs, curbs, sidewalks, trees, utility improvement
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 Township Engineer shall provide the applicant's
engineer with the existing and anticipated peak-hour flows for the
off-tract improvement.
(2) The applicant shall furnish a plan for the proposed
off-tract improvement, 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
|
C. Drainage improvements. For stormwater and drainage
improvements, including the installation, relocation or replacement
of storm drains, culverts, catch basins, manholes, riprap or improved
drainage ditches 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 the design of the drainage system
to accommodate stormwater runoff shall be based on a method described
in Urban Hydrology for Small Watershed Technical Release 55, Soil
Conservation Service USDA, January 1975, as amended, and shall he
computed by the developer's engineer and approved by the Township
Engineer.
(2) The capacity of the enlarged, extended or improved
system required for the subdivision and areas outside of the developer's
tributary to the drainage system shall be determined by the developer's
engineer, subject to approval of the Township Engineer. The plans
for the improved system shall be prepared by the developer's engineer
and the estimated cost of the enlarged system calculated by the Township
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
|
|
Development cfs
|
D. Detention/retention stormwater control improvements.
For stormwater control, detention and/or retention basins designed
for a regional or district system shall be provided. The plans for
the system shall be prepared by the Township and other concerned agencies.
The method of computing the developers pro rata share shall be determined
by the Township on a region by region or district by district basis.
The method shall be designed to take into account the nature of the
drainage areas and proposed developments and to proportion the cost
of the improvements according to the impact of each development. Methods
may include, but not be limited to, per lot; per square foot of impervious
coverage increased; the amount of storage required for on-site control;
or the amount of increased runoff compared to total increase.
[Added 11-18-1991 by Ord. No. 91-33]
Where the proposed off-tract improvement is
to be undertaken at some future date, the moneys required for the
improvement shall be deposited to the credit of the Township in a
separate account until such time as the improvement is constructed.
If the off-tract improvement is not begun within 10 years of deposit,
all moneys and interest shall be returned to the applicant.
In any case in which an applicant shall not
provide the approving authority with the estimates of a traffic consultant
and/or consulting engineer with regard to estimated improvement costs
and all other information necessary to proportion costs, the approving
authority may rely on the estimates of the Township Engineer and/or
the Director of Planning in order to prorate costs.
