All streets and alleys shall be improved solely at the expense of the developer in accordance with the requirements set forth herein.
All streets shall be graded as hereinafter provided.
A. 
New streets.
(1) 
All new streets which are created and dedicated for use within a subdivision shall be graded, drained and surfaced in accordance with the minimum requirements hereinbelow set forth and in a manner which will provide complete and adequate drainage of all the streets, alleys, and public grounds which may be necessary in order to provide adequate and satisfactory drainage along the side of any existing public street which lies adjacent to the subdivision.
(2) 
In general, all such new streets within the subdivision and all work to be undertaken thereon shall be designed and constructed according to IDOT Roads and Bridges Standard Specifications as the same are in effect at the time the preliminary plat and plans for such improvement work are submitted for approval.
B. 
Grading roadway and side slopes. The roadway shall be considered to be that part of the improvement which lies between the right-of-way lines.
A. 
Portland cement concrete pavement.
(1) 
Design thickness shall be:
(a) 
Residential. Seven-inch, nonreinforced with sawed contraction joints at a maximum of fifteen-foot intervals (and other joints per detail).
(b) 
Commercial and industrial. Minimum thickness of seven inches; pavement designs and thickness in excess of minimum shall be established utilizing the current Illinois Department of Transportation Design Standards for the particular situation and as approved by the Village Engineer.
(2) 
Longitudinal construction joints shall be tied with #4 deformed tie bars, 30 inches long at thirty-inch intervals.
(3) 
Concrete requirements.
(a) 
The concrete shall have a minimum compressive strength of not less than 3,500 pounds per square inch or a minimum modulus of rupture of not less than 650 pounds per square inch at an age of 14 days.
(b) 
Have a workable slump approved by the Village Engineer, but in no instances greater than four inches.
(c) 
Mix shall be submitted to the Village Engineer for approval prior to beginning concrete construction operations; test data must accompany the mix proportions to verify the strength of the proposed mix.
(d) 
Be field tested for strength by the Engineer or independent testing laboratory during construction by taking beam or cylinder specimens at a minimum rate of two per 500 feet per land or two per day, whichever is greater.
(e) 
Be cured by standard procedures, as approved by the Village Engineer.
(f) 
Be finished with a finishing machine approved by the Village Engineer; the machine shall be self-propelled, capable of striking off, consolidating and finishing the concrete of the consistency required to the proper crown and grade, or other method approved by the Village Engineer.
(g) 
Be air entrained (4% to 7%) and field tested to verify this air entrainment.
(4) 
The subgrade shall meet the requirements set forth in this chapter.
B. 
Hot-mix pavement.
(1) 
Design thickness shall be:
(a) 
Residential. Three-inch hot-mix asphalt surface course and 4 1/2 inches of hot-mix asphalt base course. Other pavement designs may be submitted for approval by the Village Engineer with the proper documentation as outlined in the Illinois Department of Transportation Design Standards.
(b) 
Commercial and industrial. Design criteria for the pavement design and thickness in excess of the residential requirements shall be established using the current Illinois Department of Transportation Design Standards for the particular situation and as approved by the Village Engineer.
(2) 
If, upon approval, a different pavement design aggregate base course is used, it shall be aggregate base course Type B from Section 402 of the current Standard Specifications for Road and Bridge Construction, Illinois Department of Transportation. The guidelines as set forth in Sections 402 and 403 of the above-mentioned standards shall be followed. Base course thickness shall be as set forth in the approved pavement design and shall be treated with a bituminous prime coat prior to the application of the hot-mix asphalt surface course.
(3) 
The subgrade shall be prepared so that after compacting it will conform to the alignment, grade and cross section shown on the approved plans. Soft and unstable material that will not compact shall be removed and replaced with material approved by the Village Engineer. The entire subgrade shall be compacted to not less than 95% of the standard laboratory density.
(4) 
The hot-mix asphalt surface course, hot-mix asphalt base course and hot-mix asphalt binder courses shall meet the requirements of the Illinois Department of Transportation.
Alleys, where permitted or required, shall be constructed as specified for local streets.
Underground utilities in streets or rights-of-way or in easements shall be installed prior to the construction of such streets and/or alleys. Wherever possible, utilities will be placed in rear lot easements, with street placement permitted in only the most unusual circumstances.
A. 
All streets, except alleys, shall be constructed with Type A or B Portland cement concrete curb and gutter and/or V-type gutter in accordance with the dimensions and specifications shown.
B. 
The concrete curb and gutter shall be constructed separate or integral, by hand or machine, as approved by the Village Engineer.
C. 
The concrete curb and gutter shall satisfy the requirements of Section 616 of the Standard Specifications for Road and Bridge Construction, Illinois Department of Transportation, or as approved by the Village Engineer.
The earth subbase shall be compacted to not less than 95% of the standard laboratory density and shall extend across the entire width of the roadway. Soil analysis shall be performed to determine the standard laboratory density in accordance with Article 207.05 of the current edition of the Illinois Department of Transportation's Standard Specifications for Road and Bridge Construction. The results of the soil analysis shall be filed with the Village Engineer, and compaction testing of the earth subbase shall be required in the areas of both driving lanes at a minimum sampling rate of one test per lane per 500 lineal feet of roadway length. All tests required shall be run by the subdivider's authorized agent and the results, along with the certification of the subdivider's engineer, shall be filed with the Village Engineer.
A. 
Subsequent to completion of street construction by the subdivider, the Village Engineer shall make a final inspection of all streets to ascertain the acceptability of structural condition, earth slopes, drainage structures, etc. If said inspection indicates no deficient items, the Village shall take formal action to accept the completed streets for maintenance based upon the Engineer's recommendation.
B. 
Should any item need correction or repair, the subdivider will be notified in writing of each deficiency. No street(s) shall be accepted in a subdivision until all streets comply with the Village's requirements to the satisfaction of the Village Engineer. In addition, the developer shall be required to provide a guarantee in the form of a surety bond in the amount of 25% of the approved construction cost estimate for a period of two years.
