(a) Conformity with Village Plan. The arrangement, character, extent, width and location of major, secondary and minor streets or highways shall conform with the Thoroughfare Plan for the Village and with the provisions of these Subdivision Regulations. Streets not contained in the Thoroughfare Plan shall conform to the recommendation of the Planning Commission based on existing and planned streets, topography, public safety and convenience, and proposed uses of land.
(b) Arrangement. Residential streets shall be designed to discourage through traffic which may otherwise use secondary or major streets, and whose origin and destination are not within the subdivision.
Where a railroad crossing is involved the plan of the subdivision will be considered in its relation to the probability of grade separation or other treatment, and may be required to conform to certain conditions in anticipation of such treatment. Where the subdivision adjoins a railroad right-of-way and the Master Plan indicates that such property will be used for industrial purposes, streets, in the same general direction as the railroad shall be as nearly parallel to such railroad right-of-way as may be practicable.
(c) Cul-de-sacs. The maximum length of a cul-de-sac shall be 600 feet. Each cul-de- sac shall be provided with a turn around having a minimum right-of-way radius of fifty feet. The road surface within the cul-de-sac right of way shall have a minimum radius of forty feet.
(d) Intersections. Streets shall intersect one another at an angle as near to a right angle as possible, and no intersections of streets at angles less than sixty degrees shall be approved.
(e) Width and Pavement. Unless otherwise shown on the Master Plan, the following standards shall be followed:
Major Streets | Right of Way Width (Feet) | Pavement Back Curb (Feet) |
Primary-dual roadway | 120 | 70 |
Primary-single roadway | 90 | 64 |
Secondary | 80 | 38 |
Minor Streets | ||
Multiple Dwelling Use | 60 | 38 |
Single-family dwelling use | 50 | 27 |
Alleys | 20 | |
Pedestrian Ways | 10 | |
Sidewalks | 5 | |
(f) Street Grades. The grades in all streets, alleys, and pedestrian ways included in any subdivision shall not be greater than the maximum grades as follows, except where topographical conditions unquestionably justify or departure from this maximum. All streets shall have a grade of not less than five tenths of one percent (0.5%).
Type of Street | Maximum Grade |
Major Streets | |
Primary | 5% |
Secondary | 7% |
Minor Streets | 10% |
Cul-de-sacs | 10% |
Alleys | 10% |
Pedestrian Ways | 12% |
(g) Street Alignment. The horizontal and vertical alignment on all streets except in unusual cases, shall be as follows:
(1) Horizontal. Radii of center line.
Major Streets | |
Primary | 500 feet minimum |
Secondary | 300 feet minimum |
Minor Streets | 200 feet minimum |
There shall be a tangent between all reversed curves of a length in relation to the radii of the curves so as to provide for a smooth flow of traffic. In no case shall this distance be less than 100 feet.
(2) Vertical. All changes in street grade shall be connected by vertical curves of such length as to provide for the minimum sight distances as follows:
Major Streets | |
Primary | 500 feet |
Secondary | 300 feet |
Minor Streets | 200 feet |
(h) Street Names. Names of new streets shall not duplicate existing or platted streets. New streets which are extensions of or in alignment with existing streets shall bear the name of the existing streets.
(i) House Numbers. House numbers shall be assigned in accordance with the house numbering system now in effect in the Village.
(j) Dedication. Approval of a plat shall not be an acceptance by the public of the dedication of any street, highway or other way shown on the plat.
(k) Dead-end Streets. Dead-end streets, designed to be so permanently shall not be permitted.
(l) Half-Streets. Dedication of half-streets shall be discouraged. Where there exists a dedication or platted half-street or alley adjacent to the tract to be subdivided, the other half street shall be platted if deemed necessary by the Commission.
(m) Alleys. Alleys shall not be permitted in residential areas. In commercial and industrial areas, alleys shall be required if no other provisions are made for adequate service access such as off-street parking and loading. Dead-end alleys shall not be permitted.
(n) Visibility. A twenty foot area of unobstructed vision at all corners of any street intersection shall be provided. The area shall be kept clear of all structures and vegetation exceeding a height of two and one-half feet above the curb line.
(o) Easements. Easements shall have a minimum width of five feet on each side of a lot line or such additional width as may be required for necessary access to the utility involved or to accommodate face drainage. A two foot easement shall be required on each side of an alley to accommodate pole lines. Easements shall be located along rear or side lot lines or along alleys. For lots facing on curvilinear streets, the rear easement should consist of straight lines with a minimum number of points of deflection.
Where a subdivision is traversed by a water course, drainage way, channel, or stream, there shall be provided a storm water easement or drainage right-of-way conforming substantially with the lines of such water course, and such further width or construction that will be adequate for such purpose.
