Every developer, as a condition for approval of a subdivision or site plan, whether from the Planning Board or Board of Adjustment, shall be required to pay the developer's 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 or development but necessitated or required by construction or improvements within such subdivision or development. The off-tract improvements for which the developer must contribute shall be based on the circulation plan and the utility service plan elements of the Master Plan. If no other property would obtain a significant benefit from such improvements, the developer shall pay the entire cost thereof. If other property within a related and common area would obtain a benefit from such improvements, then the approving authority shall determine the proportionate share of each element of the improvements, which shall be borne by each developer within such area. Where a developer pays the amount determined as the developer's pro rata share under protest, the developer shall institute legal action within one year of such payment in order to preserve the right to a judicial determination as to the fairness and reasonableness of such amount.
