The applicant's proportionate share of street improvements, alignment, channelization, barriers, new or improved traffic signalization, signs, curbs, sidewalks, trees, utility improvements covered elsewhere, the construction or reconstruction of new or existing streets, other associated street or traffic improvements, any land acquisition, and other related costs shall be as follows:
[1] The Municipal Engineer shall provide the applicant with the existing and reasonably anticipated future 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 and the proportion thereof which is to be accommodated by the proposed off-tract improvement. The ratio of the peak hour traffic generated by the proposed development which is to be accommodated by the off-tract improvement shall form the basis of the proportionate share. The proportionate share shall be computed as follows:
[3] Existing roads contiguous to the property are the sole responsibility of the developer which shall reconstruct such roadway to the center line and extend all related utilities through the improved section.
[4] Reconstruction of existing Township roads on the opposite side of the center line deemed necessary by the Township Engineer to assure roadway safety shall be the responsibility of the developer along undeveloped frontage.
