Union Township City Zoning Code
§ 30-23.3
Other Improvements.
[Ord. No. 85-9, § 2302]
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 developers 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 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 Union Township sewer design standards, including infiltration standards, and all other Township storm water drain standards.
2.
Developer's Pro Rata Share.
(a)
The capacity of the existing system to serve 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 cost or improvement cost Developer's cost | = | Total tributary gpd Developer's 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 Developer's cost | = | Total tributary gpd to new system Development tributary gpd |
(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 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 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 Developer's cost | = | Future peak hour traffic 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 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, January 1975, as amended, 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 Developer's cost | = | Total tributary cfs Development cfs |
