The following minimum standards shall apply to the design of minor residential streets, including marginal access streets.
(A) Roadway pavement.
(1) All streets and alleys within the subdivision shall be improved with a durable all-weather bituminous concrete or concrete surface roadway. The pavement shall be equal to or superior to a pavement consisting of a base course of a total thickness of not less than that shown in the table in division (B)(6) below when thoroughly compacted. Materials and method of construction shall be in compliance with the Standard Specifications for Road and Bridge Construction, State Department of Transportation, current edition and the current edition of the State Department of Transportation Design Manual, and shall be sufficient, in the opinion of the Village Engineer, to withstand the traffic that the roadways will presumably be subjected to.
(2) All streets shall be improved with roadway pavements to an overall width in accordance with the following minimum dimensions:
Pavement Width (Between Back of Curbs) | ||
Type of Street | Residential Subdivision | Manufacturing or Business Subdivision |
Pavement Width (Between Back of Curbs) | ||
Type of Street | Residential Subdivision | Manufacturing or Business Subdivision |
Alleys | 20 feet | 20 feet |
Collector streets | 36 feet | 50 feet |
Cul-de-sac streets | 36 feet | 40 feet |
Frontage roads | 26 feet | 36 feet |
Half street | 1/2 the width of proposed street but not less than 20 feet | Not permitted |
Minor streets | 36 feet | 40 feet |
Thoroughfares | In accordance with federal, state, county and local requirements | |
(3) Roadway pavements in cul-de-sac street terminus shall have a minimum diameter, measured from backs of the outside curb of 100 feet for residential subdivisions and 110 feet for manufacturing and business subdivision. Roadway pavements in “T” type or other types of terminus shall be as required by the Village Board.
(B) Roadway stabilization fabric (support membrane). Roadway pavements shall be installed in accordance with the following minimum requirements.
(1) All streets within the subdivision shall be improved with the use of a roadway stabilization fabric installed between the earth subgrade and the aggregate base course. This fabric shall extend the full width of the proposed pavement and be turned up eight inches on each side. All laps shall be a minimum of 24 inches.
(2) Stabilization fabric must be composed of rot-proof, low water-absorbent fibers. The fiber network (woven or nonwoven) must be dimensionally stable (i.e., fibers must maintain their relative position with respect to each other) and resistant to delamination. The fabric must be new, and free from any flaws or defects which might significantly alter its physical properties. Torn or punctured fabric shall not be used.
(3) The following physical property requirements must be met:
Grab elongation (ASTM D1682) | 20% |
Grab strength (ASTM D1682) | 300 lbs. |
Puncture strength (ASTM D751) | 100 lbs. |
Weight (ASTM D1910) | 6.0 oz./sq.yd. |
(4) After the stabilization fabric is installed, a minimum thickness of six inches of aggregate base shall be placed before any traffic is permitted over the fabric. The aggregate shall be placed by dumping into a pile and then pushing the fabric. The spreading equipment shall not damage the fabric. If any fabric is damaged, it shall be repaired immediately. Repairs shall be made in accordance with manufacturer’s specifications with minimum overlap of 24 inches.
(5) Overlaps and turned-up edges will not be included in the payment measurements for square yards of fabric. The fabric shall be “Typar” as manufactured by DuPont, or an approved equal.
(6) Minimum roadway requirements shall consist of the following:
Base Course | Residential | Manufacturing or Business |
Base Course | Residential | Manufacturing or Business |
Crushed stone or | 9 inches | 10 inches |
Bituminous aggregate mixture | 4 inches (over 4 inches CA-6) | 6 inches (over 4 inches CA-6) |
Surface | ||
Bituminous surface: | ||
Binder course | 1-1/2 inches | 2 inches |
Surface course or | 1-1/2 inches | 2 inches |
Portland cement concrete pavement | 6 inches (over 4 inches CA-7) | 8 inches (over 4 inches CA-7) |
(7) No bituminous concrete surface course shall be placed until the construction season following the construction season that the base course was installed, allowing one winter for any settlement of sub-base or trenches.
(C) Curbs and gutters. Concrete curbs and gutters shall be constructed along the outside edges of all street pavements of the type designated by the Village Engineer and installed in accordance with village standards and specifications. In no case shall the total width of the combination curb and gutter be less than 24 inches and the gutter flag thickness be less than eight inches. The curb and gutter proposed typical section shall be approved by the Village Engineer prior to final plans being approved.
(D) Access driveways. A paved access driveway from the street lot line to the street pavement shall be provided. Pavement shall be of concrete (six-inch thickness with W.W.M.) construction installed in accordance with village standards and specifications.
(E) Side strips (parkways). Side strips shall be required on both sides of all streets. They shall be graded and prepared for seeding by the subdivider with at least four inches of top soil. Median strips shall be considered as side strips unless paved.
