Access to Other Than Arterial Streets. Based upon any PennDOT review comments, the Williams Township Comprehensive Plan, and any reviews by the Planning Commission, Police, and Township Engineer, the Board of Supervisors may require that a planned unit commercial development not have any direct access that would involve left-hand turns onto and off of an arterial street (except at an intersection planned for or with an existing traffic signal), if reasonable access could be provided off and onto a collector or suitable local street.
