The right-of-way width for all streets (residential local, residential collector streets and minor arterial streets), shall be in accordance with division (L) below.
(A) (1) Streets shall be constructed in accordance with requirements of this chapter and other construction standards of the village.
(2) If streets larger than that required for the subdivision are necessary and appropriate, the village may participate in accordance with any such policies in effect at the time the subdivision is considered.
(B) All street construction shall be done in accordance with the Standard Specifications for Road and Bridge Construction of the state, latest edition, and in accordance with the approved construction plans.
(C) All underground utilities that lie or cross under the proposed pavement shall be constructed prior to any street construction. Trenches shall be backfilled in accordance with the Illinois Department of Transportation Standard Specifications for Road and Bridge Construction (latest edition) and Supplemental and Recurring Special Provisions gradation FA-6 and compacted by approved methods to a point five feet behind the curb. All underground utilities that cross under existing pavement shall be backfilled with Illinois Department of Transportation Standard Specifications for Road and Bridge Construction (latest edition) and Supplemental and Recurring Special Provisions gradation FA-6 and the disturbed pavement restored with an equal or greater strength pavement cross-section.
(D) Streets with an aggregate base course shall be constructed so that the aggregate base course can be exposed through one winter season prior to being surfaced.
(E) Sidewalks shall be constructed of portland cement concrete and shall be at least five feet wide and four inches thick. Sidewalks may be waived by Planning and Zoning Commission, but only after specific exception as outlined in the table Street Classification and Design Standards set forth in division (L) below.
(F) (1) The standard curb and gutter required adjacent to flexible pavement shall be a mountable type constructed of portland cement concrete with the following dimensions: 24 inches wide, eight inches thick on the front face pavement side, ten inches thick on the back face, seven inches thick at centerline (flow line) and a ten-inch radius in the flow line. The curb and gutter adjacent to concrete pavement, if poured monolithically, may be limited to the thickness of the pavement. When poured separately, D-form, tie bars shall be placed in the pavement in accordance with the state’s Standard Specifications for Road and Bridge Construction and shall be poured to full thickness as described above.
(2) In subdivisions proposed to have streets with an anticipated daily traffic volume of 2,500 or more, a barrier-type curb and gutter similar to Type B6.18 as described in the State Department of Transportation Highway Standards shall be used. Other locations where a barrier-type curb and gutter are required shall be determined by the engineer for the subdivision and Village Engineer.
(G) If the pavement subbase is unstable, as indicated by the proof roll(s), lime stabilized soil mixture shall be utilized. The lime stabilized soil mixture shall be prepared in accordance with the Illinois Department of Transportation Standard Specifications for Road and Bridge Construction, latest version and supplemental and recurring special provisions.
(H) Street improvements shall be in accordance with the Illinois Department of Transportation Standard Specifications for Road and Bridge Construction, latest version, supplemental and recurring special provisions and the Street Classification and Design Standards table. All street construction shall be subject to final inspection and recommendation for acceptance by the Village Engineer and Trustee in charge of streets.
(I) Before pavement construction can begin, the entire subgrade shall be compacted to not less than 95% of the standard laboratory density. Densities shall be determined as provided in the latest revised edition of the state’s Standard Specifications for Road and Bridge Construction. The number of density tests required shall be determined by the Village Engineer. Proof rolling may also be required by the Village Engineer.
(J) If it is found that the subgrade cannot be compacted, it shall be removed and replaced with suitable materials. The depth to which this unsuitable material is replaced shall be determined by the Village Engineer.
(K) Portland cement concrete pavement construction shall be completed without delay and shall be closed to traffic for 14 days after placement or seven days with a modulus of rupture of 650 pounds per square inch. The density of the compacted bituminous mixture shall be determined as outlined in the state’s Standard Specifications for Road and Bridge Construction.
(L) The minimum crown used on all pavements shall be one quarter inch per foot measured from the edge of the pavement to the centerline of the street. The right-of-way width for all streets (residential. local, residential collector streets and minor arterial streets) shall be in accordance with the table below.
