1. All curbs and/or curb ramps shall be constructed, reconstructed or designed in accordance with PennDOT Publication 72M and PennDOT Publication 408, as each may be amended from time to time; and shall also comply with current ADA standards in place at the time of construction or reconstruction.
2. The physical geometry of the ramps shall comply with PennDOT Publication 72M and PennDOT Publication 408, as each may be amended from time to time. The design of the ramps shall also comply with PennDOT Design Manual Part 2, Highway Design Publication 13M as may be amended from time to time.
3. In built up areas, the proposed curb reveal shall match the reveal of the existing adjacent curb if the adjacent curb is four (4) inches or more in height. If the existing curb has a reveal less than four (4) inches, the replacement curb shall have the minimum reveal of four (4) inches. The required curb reveal will be determined by the Borough Engineer in accordance with PennDOT Publication 72M and PennDOT Publication 408, as each may be amended from time to time. The contractor shall prepare for this meeting by surveying the 50 feet of existing curbing immediately adjacent on each side of the proposed run of curbing. The contractor shall prepare a scale drawing (scale: 1 inch = 25 feet horizontal; 1 inch = 5 feet vertical) showing the existing gutter line and top of curb profile on each side of the proposed run of curbing. The Borough Engineer may require a site meeting to review the proposed curb reveal.
4. When a curb joins with a tangent curb, at curb returns, on sharp curves where a curb is jointed to an inlet and elsewhere as directed by the Borough, there shall be embedded in the concrete two (2) No. 4 reinforcing bars 24 inches in length. These bars shall extend 12 inches into the curb on each side of the joint. The portion of the bar extending into the tangent curb shall be rendered bondless by a coating of approved material and enclosed in tubes or caps which will provide a minimum 1/2 inch positive clearance pocket. The top surface of the curb shall be finished true to line and grade in a smooth, neat and even manner. The edge of the faces and back shall be rounded to a radius of 1 inch.
5. The depressed curb at driveways shall be no higher than 1 and 1/2 inches and no lower than 1/2 inch above the street surface. The length of this depressed curb shall not exceed 35 feet without a safety island that shall not be less than 15 feet in length. Pipes or grates or other construction shall not be placed in the gutter to form a driveway ramp.
6. Where it is necessary to replace existing vertical curbs with depressed curbing, at least two (2) sections of 10 feet in length of existing curb shall be removed down to subgrade without disturbing the adjacent cartway paving. Any portions of the cartway disturbed during curbing removal or installation shall be repaired to new condition.
7. Curb cut ramps shall be provided at all street intersections as directed by the Borough Engineer and in accordance with PennDOT Publication 72M and PennDOT Publication 408, as each may be amended from time to time.
8. All joints between curbs and pavement shall be sealed with material conforming to PennDOT Bulletin 25 or the approved equal.
