Modification of subdivision and land development standards. The uniqueness of each proposal for a planned residential development may require that the specifications for the width and surfacing of streets and highways, alleys and ways for public utilities and for curbs, gutters, sidewalks, streetlights, public parks and playgrounds, school grounds, stormwater drainage, water supply and distribution, sanitary sewers and sewage collection and treatment shall be subject to modification from the specifications established in the Subdivision and Land Development Ordinance or in certain other Township ordinances. The Board of Commissioners may, therefore, waive or modify the specifications otherwise applicable for a particular public facility where the Board of Commissioners finds that such specifications are not required in the interest of the residents of the planned residential development and that the modifications of such specifications are consistent with the interests of the entire Township. Proposed specifications and standards that are inconsistent with those required under the prevailing Township ordinances shall be termed acceptable upon approval by the Board of Commissioners.
