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 hereinafter 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 collection facilities, including
the installation, relocation or replacement of collector, trunk and
interceptor sewers and the installation, relocation or replacement
of other appurtenances associated herewith, 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,
and all Alexandria Township sewer design standards, including infiltration
standards.
(2) Developer's pro rata share.
(a)
The capacity of the existing system to serve
the entire sewerage 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 the 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 cost
|
|
|
|
or improvement cost
|
=
|
Total tributary gallons per day
|
|
Developer's cost
|
|
Developer's gallons per day
|
(b)
If it is necessary to construct a new system
in order to developer the subdivision, the prorated enlargement share
to the developer shall be computed as follows:
|
|
|
Total tributary gallons per day
|
|
Total project cost
|
=
|
to new system
|
|
Developer's cost
|
|
Development tributary gallons per day
|
(c)
The plans for the 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 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 applicant's engineer shall provide Township'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 improvements, which shall include the estimated peak-hour
traffic generated by the generated by the proposed development. The
ratio of the peak-hour 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 or improved
drainage ditches, or 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 a method described
in Urban Hydrology for Small Watersheds Technical Release 55, Soil
Conservation Service, USDA, June, 1986, and shall be 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 by 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
|
Where the proposed off-tract improvement is
to be undertaken at some future date, the moneys required for the
improvements 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 calculation
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 in order
to prorate costs.
