All curbs for the support of sidewalks hereafter to be laid shall be of the material or materials, dimensions and construction required in department specifications for such work, which shall be prescribed by the commissioner and kept on file in his or her office.
Editor's note: For related unconsolidated provisions, see Appendix A at L.L. 1993/104.
In the construction and installation of all new and reconstructed curbs at corner located street intersections and pedestrian crosswalks not located at street intersections, provision shall be made for the installation of the following: two ramps at corners located at street intersections and one ramp at pedestrian crosswalks not located at street intersections. Such ramps shall be no less than four feet wide and shall blend to a common level with the roadway. If a common level is unobtainable, then the lip of such ramps shall not exceed a maximum of five-eights of an inch and shall have a rounded edge. The slope of such ramp shall not exceed eight per cent. This section shall apply to all construction of new curbs and to all replacement of existing curbs. The commissioner shall have discretion to waive one of the two mandatory ramps at corners located at street intersections where any of the following obstacles exists preventing construction of such ramp within an intersection: fire hydrants, light poles, traffic signals, fire alarms, or free-standing police alarms, underground vaults, tunnels, utility maintenance holes (manholes), chambers or where the gradient of the street on which the ramp is to be located or an intersecting street exceeds a gradient of 1:8. The commissioner may waive the construction of both such ramps where the existence of underground vaults, tunnels, utility maintenance holes (manholes) and chambers would either prevent the safe construction of such ramps or render impossible the construction of such ramps to proper specifications without removal of said underground installations. A certification to such effect shall be made part of the engineering design documents for such construction, and a copy thereof shall be filed with the city clerk. Curbs for non-pedestrian routes, such as, but not limited to, service paths for highways and pedestrian restricted traffic islands shall not be subject to the provisions of this section.

a. Streets of twenty-two feet in width and upward shall have sidewalks on each side thereof.
b. The materials and construction of streets, including the width of the sidewalks thereon, shall fully conform to department specifications for such work, all of which shall be prescribed by the commissioner and kept on file in his or her office.
c. Department specifications for streets shall include a requirement that asphaltic concrete, other than I-4 mix or other heavy duty asphaltic concrete mix approved by the commissioner, shall contain not less than thirty percent reclaimed asphalt pavement, as measured by weight, and I-4 mix or other approved heavy duty asphaltic concrete mix shall contain not less than ten percent reclaimed asphalt pavement, as measured by weight. In setting forth such specifications, the department shall make best efforts to encourage the greatest use of reclaimed asphalt pavement possible. This subdivision shall not apply to asphaltic concrete used in a project where the content of asphaltic concrete is governed by a federal or state law, rule, regulation, guideline or specification that requires a different composition. The commissioner may waive compliance with this subdivision if the commissioner, after consulting with the commissioner of buildings and the owners or persons in charge of all asphalt plants located within the city, finds that a sufficient supply of reclaimed asphalt pavement is not available.

The commissioner shall cause a covenant to be incorporated in all contracts hereafter made by him or her for constructing, regulating or repairing any street, requiring the contractor to obtain the permit required pursuant to section 3-508 of the code and to take such other precautions for the care and preservation of monuments, bolts and other landmarks as the commissioner may direct.

The commissioner may issue a permit to allow any person or persons to pave the street opposite to his, her or their property, where the same shall extend from the intersection of one cross street to the intersection of another. Such work shall be done in conformity with the rules and specifications of the commissioner and subject to such conditions as he or she may impose.
