(A) (1) The arrangement of streets in new subdivisions shall make provisions for the continuance of existing streets in adjoining areas.
(2) Where adjoining areas are not subdivided, the arrangement of streets in new subdivisions shall make provision for proper projection of dedicated streets to the boundaries of the subdivision or development.
(B) The arrangement, width, grade and location of all streets shall be considered in their relation to existing topographical conditions and safety.
(C) The proposed street network shall conform to the Comprehensive Plan.
(D) When a subdivision abuts or contains an existing or proposed major thoroughfare, the Planning Commission may require marginal access streets, reverse frontage lots with screen plantings, rear service alleys or such other treatment as may be necessary to provide separation of through and local traffic.
(E) Reserve strips controlling access to streets shall be prohibited, except where their control is placed with the village under conditions approved by the Planning Commission.
(F) Street jogs with centerline offsets of less than 125 feet shall be avoided.
(G) Streets shall be laid to intersect as nearly as possible at right angles. No street shall intersect any other street at less than a 75-degree angle.
(H) Property lines at street intersections shall be rounded or clipped as necessary to provide sufficient space for the intersection radii, sidewalk ramps and traffic control devices.
(I) Dead end streets shall be provided with a turnaround cul-de-sac having an outside pavement diameter of at least 80 feet and a street right-of-way diameter of at least 100 feet. The length of a dead end street shall not exceed 600 feet measured from the center point of the turn-around to the centerline of an intersecting street.
(J) Access to state and county highways at intervals of less than 1,320 feet shall not be allowed, except where impractical or impossible due to existing property divisions or topography. Streets within new subdivisions shall be arranged to permit access to adjacent future subdivisions to meet this requirement.
(K) All underground utilities that lie or cross under the proposed pavement shall be constructed prior to any street construction. Trenches shall be backfilled with either flowable fill or select granular backfill to a point two feet behind the curb. If street pavement is to be constructed in the same season the trench is installed, flowable fill shall be used as the backfill material. Trenches allowed to settle through a winter and spring season before pavement is installed can be backfilled with select granular backfill and compacted mechanically to 95% SPD in minimum 12-inch loose lifts.
(L) Streets constructed outside the corporate limits of the village, but within the mile and one-half extraterritorial jurisdiction shall also conform to the rules, specifications and regulations regarding location, width, grades, surface and drainage structures applicable to the township road system. The review, approval and acceptance of roads or streets in the township is performed by the township Highway Commissioner, in coordination with the village, and acceptance shall be filed with the County Clerk and County Engineer.
(M) The location of trees planted in parkways or street rights-of-way is subject to approval of the Village Engineer. Trees should be a minimum of two-inch caliper. The recommended types of trees are: Norway Maple; Red Maple; Amur Cork-Tree; Little Leaf Linden; Common Hackberry; or American Linden.
(N) Street functional classification and characteristics shall be as follows:
Classification1 | ROW Width | Pavement Width | Curb and Gutter | Grass Buffer Width (SW to Curb) | Sidewalk Width | Minimum Design Speed |
Arterial | 75 feet2 | 44 feet2 | B-6.18 | 7.5 feet | 5 feet | 30 mph |
Collector | 60 feet2 | 34 feet2 | B-6.18 | 5 feet | 5 feet | 30 mph |
Local street | 55 feet | 29 feet | B-6.18 | 5 feet | 5 feet | 20 mph |
NOTES TO TABLE:
1 The village may consider variations of the classification and cross-section widths if the subdivider presents unique characteristics or conditions that warrant special consideration. For example, industrial, commercial and residential subdivisions will be designed based on their respective land use. 2 If traffic studies indicate that more than two lanes for through traffic and/or turning traffic are necessary, the pavement and right-of-way widths shall be increased accordingly. The Village Engineer shall evaluate traffic studies prepared by the subdivider’s engineer to assist in this evaluation. | ||||||
(O) Geometric design policies for village roadways shall be as stated in the most recent version of the state’s Department of Transportation’s Bureau of Local Roads and Streets Manual. More specifically, horizontal alignment shall comply with the low-speed urban streets criteria unless directed otherwise by the Village Engineer.
(P) Design speed shall control roadway design values. Design speed for all subdivision streets shall be established in cooperation with the Village Engineer during the pre-application process or in the early stages of the preliminary plat process. Design speed values provided in the table above may be modified by the Village Engineer.
(Q) Pavement material and thickness design shall be in accordance with the most recent version of the state’s Department of Transportation’s Bureau of Local Roads and Streets Manual. More specifically, Ch. 44 in the 2012 manual version. The rigid (PCC) pavement design or full-depth HMA pavement design shall be used for subdivision streets. For all pavements, a granular sub-base not less than eight inches shall be constructed.
(R) Longitudinal slopes of pavements and gutters shall not be less than 0.5%.
(S) (1) Driveway widths shall not be less than 12 feet wide and not more than 35 feet wide. A residential property may only have one driveway and that driveway may not be wider than 24 feet at the property line. Residential driveways shall be concrete and not less than six inches thick within the public right-of-way.
(2) Commercial and industrial zoned properties must also build concrete driveways within the public right-of-way and the concrete must be not less than eight inches thick.
