A. Every developer making application for development which requires or will benefit from the installation of off-tract sanitary sewerage, storm drainage or street improvements shall contribute to a fund hereinafter established for the construction of the off-tract facilities.
B. Contributions shall be made for each improvement. The amount of the contribution shall be determined as follows:
Contribution = Pro Rata Share x Estimated Cost of Facility
(1) A developer's pro rata share and the estimated cost of facility shall be determined as described in this chapter for each required sanitary sewerage, storm drainage and street improvement.
(2) The amount of the contribution shall be determined at the time of preliminary subdivision or preliminary site plan approval.
C. Sanitary sewerage. Contributions for off-tract sanitary sewerage facilities shall be required to fund the construction, reconstruction or replacement of sanitary sewer lines and pumping facilities which are necessitated by development within the township.
(1) As part of the Utilities Element of the Master Plan, the Planning Board shall estimate the total sewerage flow from potential developments within the township's designated sewer service area, distribute the flows to the various required facilities, and then calculate each developer's pro rata share of the required improvement. A developer's pro rata share shall be determined as follows:
Pro Rata Share Development Flow
Total New Flow
(2) The parameters in the above equation are defined as follows:
(a) "Development drainage area" shall be that portion of a development site which drains to the improvement under consideration, in acres.
(b) "Total drainage area" shall be the total area which drains to the improvement under consideration, in acres.
D. Storm drainage. Contributions for off-tract storm drainage improvements shall be required to fund the construction, reconstruction, or replacement of storm water pipes, culverts, channels, and detention basins which are necessitated by runoff from development within the township.
(1) A developer's pro rata share shall be determined as follows:
Pro Rata Share Development Drainage Area
Total Drainage Area
(2) The parameters in the above equation are defined as follows:
(a) "Development drainage area" shall be that portion of a development site which drains to the improvement under consideration, in acres.
(b) "Total drainage area" shall be the total area which drains to the improvement under consideration, in acres.
E. Street improvements. Contributions for off-tract street improvements shall be required to fund intersection and roadway improvements which are necessitated by traffic generated from new development within the township.
(1) Transportation improvement district. A Transportation Improvement District is hereby established in the northern, developing portion of the township. The purpose of the district is to establish a geographic area wherein the township can establish a rational nexus between traffic generated by new development and improvements required to the existing street system as a result of the new traffic. The district boundaries have been established to include all tracts in the northern part of the township which are zoned for major development and also to contain streets and intersections where improvements will be required as a result of development. A plan showing the limits of the Transportation Improvement District shall be included as part of the Circulation Plan Element of the Master Plan.
(2) As part of the Circulation Plan Element of the Master Plan, the Planning Board shall estimate new traffic from all potential developments within the Transportation Improvement District, assign the trips to the various roadways and intersections within the district and calculate each developer's pro rata share of the required improvements. A developer's pro rata share shall be determined as follows:
Pro Rata Share Development Peak Hour Traffic
Total New Peak Hour Traffic
(3) The parameters in the above equation are defined as follows:
(a) "Development peak hour traffic" shall be that portion of the total peak hour traffic generated by a proposed development which impacts the improvement under consideration.
(b) "Total new peak hour traffic" shall be the total traffic generated by all new development within the Transportation Improvement District, including background growth, which will impact the improvement under consideration.
F. Estimated cost of facilities. The estimated cost of off-tract sanitary sewerage, storm drainage and street improvements shall be determined by the Planning Board Engineer at the time of the first contribution for the improvement and shall include all design, right-of-way acquisition, construction, and construction inspection costs necessary for completion of the project. The Planning Board Engineer shall prepare a detailed cost estimate and shall file copies in the Township Clerk's office. The estimate shall include a base cost index which shall be the current value of the Engineering News Record construction cost index. Contributions by other developers at a later date shall be based on the original cost estimate, adjusted by the ratio of the latest cost index to the base cost index.
