An applicant shall provide sidewalks where their production
is in accord with proper design of his project, consistent with prevailing
community standards in the area in which the applicant's project is
located and consistent with aesthetic principles.
Sidewalks shall be required at the reviewing board's discretion
depending on the probable value of pedestrian traffic, the street
classification in instances where streets are involved, school bus
stops, the development's location in relation to other populated areas,
and the general type of improvement intended. Where required, sidewalks
shall be at least four feet wide and located as approved by the approving
authority. Sidewalks shall be at least four inches thick, except at
points of vehicular crossing where they shall be at least six inches
thick, having a twenty-eight-day compressive strength of 4,500 psi,
and shall be air-entrained.
