All streets under the jurisdiction of the Village shall be classified by the Village and said classification shall determine the standards to which said streets must be constructed. If the proper classification of any street is unknown, or if a new street is proposed for construction, the Village shall review the existing or proposed street and thereafter establish a classification.
(A) As a general rule, the design of all streets within any subdivision shall be properly integrated with the Village’s existing and proposed street system, and all work, installation, procedures and testing shall conform to the specifications contained in the latest edition of the Illinois Department of Transportation “Standard Specifications for Road and Bridge Construction”, hereinafter referred to as IDOT Standard Specifications, with the provisions of this Article, and with the specifications set forth in Table 31.
(B) Measurement of pavement width for streets shall be made from back-to-back of the curbs. Measurement of pavement width for alleys, where curbs are not required, shall be from edge-to-edge.

(C) Grades of streets shall conform as closely as possible to the natural topography without exceeding the minimum or maximum standards as specified herein, and designed so that as many building sites as is possible, are at least one (1) foot above street grade.
(D) All streets shall be constructed of Portland Cement Concrete or bituminous pavement. “Oil & Chip” streets shall no longer be constructed.
(E) Alleys may be provided in single-family residential districts at the option of the developer, but may be required in other districts in the absence of other provisions for service access.
(1) When provided, alleys shall not intersect with each other or change sharply in alignment.
(2) Adequate vehicular turnaround space shall be provided at the terminus of every dead-end alley.
(F) Every concrete street, curb, and gutter, hereafter constructed in the Village, shall have a compressive strength of four thousand (4,000) P.S.I. at twenty-eight (28) days.
(1) The Subdivider or developer shall provide to the Village Engineer at no expense to the Village, concrete tests verifying compressive strength. The number of such tests shall be determined by the Village Engineer. The Village Engineer shall also have the right to request other tests, including air entrainment and slump tests, as he deems necessary.
(G) Alternative pavement designs to those contained herein, may be submitted to the Village Engineer for consideration. Such designs shall adhere to current policy of the Illinois Department of Transportation, be at least equivalent to the requirements contained herein, be signed and sealed by a Registered Professional Engineer licensed in Illinois, and certified by said engineer that the proposed design meets these requirements. This alternate pavement design must be approved, in writing, by the Village Engineer.

Notes: (1) Equivalent pavements, in addition to those shown in Table 3-B, shall be submitted to the Public Works Director or Mayor's designee for approval. (2) If total pavement thickness exceeds 8", the granular aggregate base/subbase shall extend under the curb and gutter. (3) All pavement types shall be constructed on a lime modified subgrade 12" in depth. (4) Trench drains shall be installed either side of roadway and street pavement with a profile grade greater than 5%.
