All streets shall be properly integrated with the existing and proposed street system indicated in the municipal Comprehensive Plan, and shall meet the specifications set forth in Table of Street Design Specifications included as an attachment to this chapter.
A. 
Every right-of-way established for subdivision purposes is to be separate and distinct from the lots or parcels adjoining such right-of-way and not included within the dimensions or areas of such lots or parcels. All rights-of-way shall be dedicated to the public by the developer.
B. 
The minimum pavement widths shall be as noted in the Table of Street Design Specifications included as an attachment to this chapter.
Grades of street shall conform as closely as possible to the natural topography, but shall not exceed the maximum grade nor be less than the minimum grade indicated in the Table of Street Design Specifications included as an attachment to this chapter. All streets shall be arranged so that as many as possible of the building sites are at or above street grade.
Marginal access and local streets shall be laid out so as to discourage use by through traffic. The rigid rectangular gridiron street pattern shall be avoided, and the use of curvilinear streets, culs-de-sac, or U-shaped streets shall be encouraged to effect a more desirable street layout.
Where a development abuts or contains an existing or proposed arterial street, the Plan Commission may recommend to the Village Board that access to said arterial street be limited by one of the following means:
A. 
By subdividing lots so they back onto the arterial street and front onto a parallel local street (double-frontage lots), coupled with the installation of screening in a reserve (access-restricting) strip along the rear lot lines of such lots;
B. 
A series of culs-de-sac, U-shaped streets, or short loops entered from and generally at right angles to the arterial street, with the rear lot lines of the lots at the termini of such streets backing onto the arterial street; or
C. 
A frontage road separated from the arterial street by a planting strip, but having access thereto at suitable points.
A. 
Temporary stub streets. Streets shall be so arranged as to provide for the continuation of principal streets between adjacent properties when such continuation is necessary for convenient movement of traffic, effective fire and police protection, and efficient provision of utilities, and where such continuation comports with the Village's Official Map. If the adjacent property is undeveloped and the street must dead-end temporarily, the right-of-way shall be extended to the property line, and no strip that would prevent connections with future streets shall be reserved. A temporary turnabout shall be provided at the terminus of any temporary dead-end street, if required by the Village.
B. 
Permanent dead-end streets.
(1) 
For greater convenience to traffic and more effective police and fire protection, permanent dead-end streets shall be limited to 500 feet in length.
(2) 
The terminus of a permanent dead-end street shall not be closer than 50 feet to the boundary of an adjacent tract. A cul-de-sac turnaround, having a minimum right-of-way radius of 50 feet and a minimum pavement radius of 42 feet, shall be provided at the end of every permanent dead-end street.
A. 
Only two streets. Not more than two streets shall intersect at any one point.
B. 
Right angles. Streets shall be laid out so as to intersect as nearly as possible at right angles; in no case shall two streets intersect at an angle of less than 75°. An oblique street shall be curved approaching an intersection and shall be approximately at right angles with said intersection for at least 100 feet therefrom.
C. 
Proper alignment. Proposed new intersections along one side of an existing street shall, whenever practicable, coincide with any existing intersections on the opposite side of such street. Street jogs with center-line offsets of less than 125 feet shall not be permitted, except where the intersected street has divided lanes without median breaks at either intersection. Intersections involving collector or arterial streets shall be at least 800 feet apart.
D. 
Curb radii. To permit safe vehicular movements at corners, the minimum curb radius at the intersection of two streets shall be 25 feet from back of curb.
E. 
Flat grade. Intersections shall be designed with a flat grade wherever practical. In hilly terrain, an area having not greater than a 3% slope for a distance of 50 feet from the nearest right-of-way line of the intersecting street shall be provided at the approach to an intersection.
F. 
Slope. Pavement slopes shall be a minimum of 0.4% and a maximum of 8%. There shall be a three-inch-minimum crown in all pavements.
G. 
Adequate sight lines. Where any street intersection will involve earth banks or existing vegetation, there must be adequate sight lines and distances for the traveling public, both vehicular and pedestrian. No earth banks or existing vegetation within a triangular area on a lot at the intersection of two streets, or the intersection of a street and driveway, two sides of which are lot lines measured from the corner intersection of the property lines to a minimum distance of 15 feet from their intersection and the third side of which is the line measured from the end points of each of the other two lines, shall exceed three feet in height above street grade.
[Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. I)]
A. 
A tangent at least 100 feet long shall be introduced between reverse curves on local and collector streets.
B. 
Horizontal curves in streets shall be permitted, provided no curve shall be greater than that approved by the Village Engineer as reasonably safe for traffic and the particular location of the curve.
Whenever any development abuts an existing street that is narrower than the standards indicated in the Table of Street Design Specifications,[1] the subdivider shall dedicate sufficient right-of-way on the side abutting the development to permit compliance with those standards. The developer shall improve said street to the standards imposed in § 300-60 et seq., and pay 1/2 the cost of said improvements.

Editor's Note: See Table 5-A, included as an attachment to this chapter.
Right-of-way width in excess of the standards set forth in the Table of Street Design Specifications[1] shall be required where:
A. 
Due to topography, additional width is necessary to provide adequate earth slopes; or
B. 
Due to the location of railroad tracks, additional width is needed to construct overpasses, underpasses, and approaches thereto.

Editor's Note: See Table 5-A, included as an attachment to this chapter.
Street jogs with center-line offsets of less than 125 feet shall not be permitted if the same can be reasonably avoided.
