(A) Intent. The arrangement, character, extent, width, grade and location of all streets shall conform to the Comprehensive Plan (official map) and to the provisions of this chapter and shall consider their relationship to existing and planned streets, to reasonable circulation of traffic, to topographical conditions, to runoff of storm water, to public convenience and safety, and in their appropriate relations to the proposed uses of the area to be served. The village's complete street, adopted by Village Resolution 2019-04 (codified as § 92.02), shall be followed in the design of all street and transportation systems.
(B) Design criteria. The following general design criteria for streets shall be followed:
(1) Developments planned to be constructed adjacent to existing developments must be designed to accept the alignment and corresponding widths of existing pavements unless specifically excepted by the Village Board.
(2) All right-of-way widths shall conform to the following minimum dimensions:
STREET CLASSIFICATION | MINIMUM RIGHT-OF-WAY |
Arterial | 80 feet |
Collector | 80 feet |
Minor Residential and Cul-de-Sac | 66 feet |
Marginal Access Streets | 66 feet |
Frontage Road (dedicated) | 66 feet |
(3) If the tract of land proposed to be subdivided or any part thereof lies adjacent to a highway over which the Department of Transportation of the State of Illinois or the County of Grundy or County of Will Highway Department has jurisdiction with respect to maintenance and upkeep thereof and an entrance or entrances are desired from such highway to lots, streets, roadways or alleys in the proposed subdivision, the subdivider shall submit to the Village Engineer a written permit from the department granting permission to obtain and construct such an entrance or entrances, including details thereof.
(4) When a subdivision borders on and has lots fronting on a present or proposed federal, state, county or limited access highway, necessary traffic service to the lots of the subdivision property bordering such highways shall be provided by a frontage road or marginal access street.
(5) When a street center line within a single block deflects more than 10 degrees, a curve is required. Minimum center line radius shall be:
(a) Arterial and collector streets - 300 feet.
(b) Minor residential streets and cul-de-sacs - 150 feet.
(6) The maximum length of straight center line or extension of a tangent to a curve shall be 1,320 feet for collector streets and 660 feet for minor residential streets. This shall not apply to straight streets on the boundary of a subdivision.
(7) All center line grades shall be at least 0.30% and not exceed the maximum grades, as follows:
(a) Arterial and collector streets - 4%.
(b) Minor residential streets and cul-de-sacs - 6%.
(8) Vertical curves shall be used whenever a change in center line gradient occurs.
(9) Minor residential streets shall be so aligned that their use by through traffic will be discouraged.
(10) Street jogs with center line offset of less than 125 feet shall be avoided.
(11) The design and layout of the subdivision must demonstrate that all street intersections and confluences encourage safe and efficient traffic flows.
(12) Unless included in an approved planned development, alleys are not permitted in the design of any subdivision for which final plat approval is sought on or after the date of the adoption of this chapter.
(13) The maximum length of a cul-de-sac shall be 500 feet measured along the center line from the intersection at origin to end of right-of-way, unless there are fewer than 16 lots abutting the cul-de-sac. Each cul-de-sac shall have a terminus of nearly circular shape with a minimum right-of-way diameter of 120 feet.
(14) Reserved strips of land or other means of control designed to block the extension of platted or existing streets or drains, or deny street access, are prohibited.
(15) No street names may be used which will duplicate or be confused with names of existing streets as reviewed and determined by Grundy or Will County 911 Board.
(16) Existing street names must be continued whenever possible.
(17) Streets within a development shall not be named after the developer or the name of the project unless the street is within the development and cannot be extended into other developments.
(18) All proposed street names require the approval of the Planning Commission.
(19) Driveways on main collector streets such as Route 113, Will Road, Spring Road, and Berta Road, shall be limited at the village's discretion.
(20) Parkway trees within a street right-of-way shall not be permitted unless approved as a part of a planned development.
