Notwithstanding the area and other requirements specified for the zones in the area fronting on State Highway Route 206, no development on new lots created after the adoption of this Part 5 with driveway access to or from Route 206 is permitted on such highway frontage without specific Planning Board approval based on considerations of traffic safety and lack of alternate access. The provision of access from interior streets instead of from the highway and the provision of buffer areas under cluster development to reduce exposure to noise shall be emphasized.
