1. Concrete or Belgian block curbs shall be installed on all existing and proposed streets and parking areas located within multi-family, apartment building, and nonresidential developments. Curbs shall also be required on new residential streets in subdivisions or land developments in which the minimum lot size is less than 2 acres, and all new nonresidential streets. Curbs may also be required on all streets in any subdivision in which the lot areas exceed the above minimum, when the center line street grade of any street exceeds 6 percent; and along all existing streets where deemed necessary by the Township. In such cases curbs or other drainage controls shall be installed to properly control surface drainage and protect the streets from erosion. The requirement of the curbs may be waived at the discretion of the Board of Supervisors.
2. All curbs shall be depressed at intersections to sufficient width to accommodate wheelchairs and shall be in accordance with the latest PennDOT and Americans with Disabilities Act standards.

Material shall consist of cement concrete Class “AA” with a minimum 7-day design compressive strength of 3,000 psi and a minimum 28-day design compressive strength of 3,750 psi. After completion of the bituminous paving, Class BM-1 asphalt shall be applied to the joint between the curb and bituminous paving for a distance of 1 foot from the curb toward the center of the road to seal the joint between the curb and bituminous paving.
4. Belgian block curb/paving shall be sealed in a similar manner as concrete curb except that the joint sealing material shall be placed after the bituminous concrete base course and before the final wearing course is placed. Belgian block curb shall be constructed pursuant to detail contained in Appendix “A.”
5. Curb cuts (driveway depression) shall be a maximum of 1½ inches above roadway surface, a minimum of 1 inch above the roadway surface, and a minimum of 14 feet in width. Concrete curb cuts shall have two #5 reinforcing rods placed for the full length of the depression plus 18 inches on both sides.
6. Profile of curb design along existing streets shall be shown on the plan. Profiles shall be smooth and designed with vertical curves where there is a change in grade. Breaks in grade shall not be permitted. Existing edge of road and bottom of curb elevations shall be identified every 50 feet and at locations specified by the Township Engineer.
