(A) Generally. All streets and alleys shall be improved in accordance with the standards of the Illinois Department of Transportation and the requirements of this section. (See Appendix F, Figure 6.)
(B) Pavement.
(1) All alleys, marginal access streets, and local streets in residential subdivisions shall be paved across the entire width stated in § 156.25(B) (as measured from back-to-back of curbs) with a minimum of:
(a) Portland cement concrete pavement not less than six inches in thickness reinforced with pavement fabric; or
(b) Bituminous aggregate material base course not less than five inches thick with a two-inch bituminous concrete Class I surface; or
(c) Crushed stone aggregate base course not less than seven inches thick with a three inch bituminous concrete Class I surface.
(2) On streets with heavier and/or greater amounts of traffic than local streets (such as collector streets or streets in non-residential developments), or where soil conditions are such that strengthened design is indicated, complete engineering design of the proposed pavement shall be provided by the subdivider’s professional engineer in accordance with the standards of the Illinois Department of Transportation, subject to the review and approval of the City Engineer.
(3) “Oil and chip” surfacing is not acceptable.
(C) Curb and gutter. All streets shall be bounded by integral concrete curb and gutters in conformity with the specifications illustrated in Appendix G, Figure 7; provided that the City Council may vary this requirement in accordance with
§ 156.82 if the subdivider is proposing to build streets with shoulders deemed adequate by the City Engineer:
(D) Responsibility for maintenance. The subdivider shall assume responsibility for maintaining all streets (including the seeding; removal of earth, crushed stone, or other debris from the pavement; curb and gutter; and other drainage facilities) for the time periods indicated in§ 156.67; that is, for two years after acceptance of improvements by the appropriate governmental entity. The developer shall be responsible for requesting acceptance from the appropriate governmental entity after he has completed the improvements.
