(a) The arrangement of streets shall be considered in their relation to existing and planned streets, to topographical conditions, and to public convenience and safety and in their appropriate relation to proposed uses of land to be served by such streets. The arrangement shall make provision for the continuation of the principal existing streets in adjoining areas or their proper projection where adjoining land is not subdivided.
(b) Street arrangement shall be such as not to cause hardship to owners of adjoining property when they plat their own land and seek to provide convenient access to it. Minor residential streets shall be so designed as to discourage through traffic.
(c) Where a subdivision abuts or contains an existing or proposed arterial street, the Planning Commission may require marginal access streets or such other treatment, as the fronting of all lots on minor side streets, to provide for a separation of through and local traffic and to protect residential property.
(d) Where a subdivision borders on or contains a railroad right of way or limited access highway right of way, the Planning Commission may require a marginal access street approximately parallel to and on each side of such right of way at a distance suitable for appropriate use of the intervening land.
(e) Reserve strips controlling access to streets shall be prohibited, except where their control is definitely placed in the Village under conditions approved by the Planning Commission.
(f) Streets shall be arranged to cause the least possible interference with the movement of traffic on adjoining roads. In general, minor streets shall be located not less than 125 feet from the intersection of two arterial or collector streets, measured from the center line.
(g) A tangent at least 100 feet long shall be introduced between reverse curves or arterial or collector streets. Where connecting street lines deflect from each other by more than ten degrees, they shall be connected by a curve with a radius of not less than 300 feet for arterial or collector streets, and not less than 200 feet for minor streets, all radial lines measured to the centerline of the street.
(h) Streets shall be designed to intersect as nearly as possible at ninety degrees, and no street shall intersect another at less than sixty degrees. street jogs with centerline offsets of less than 125 feet shall be avoided.
(i) Property lines at street intersections shall be rounded with a radius of at least ten feet or more where the Commission deems it necessary.
(j) Minimum street right of way widths shall be as follows:
Arterial Streets - fifty feet to eighty feet, depending upon function and design of roadway as determined by the Planning Commission.
Collector Street - 40 feet.
Minor Street - 20 feet
Alley - 20 feet.
Marginal Access Street - 50 feet
Cul-de-sac - 50 feet, with turn around diameter of 100 feet.
(k) Half streets shall be prohibited except where essential to the reasonable development of the subdivision in conformity with the other requirements of these Subdivision Regulations, and where the Planning Commission finds it will be practicable to require dedication of the other half when the adjoining property is subdivided.
(l) Dead end streets, cul-de-sacs, designed to be so permanently, shall not be longer than 500 feet and shall be provided at the closed end with a turn around having an outside right of way diameter of 100 feet.
(m) No street names shall be used which will duplicate or be confused with the names of existing streets. Street names shall be subject to the approval of the Commission.
(n) Grades of arterial and secondary streets shall not exceed five percent and grades of minor streets shall not exceed ten percent. Street grades shall not be less than 0.4 percent in order to provide adequate drainage. All changes in grade shall be connected by vertical curves of sufficient radius to provide a smooth transition and proper sight lines for vehicular operations of not less than 200 feet.
(o) Alleys shall be provided in commercial and industrial districts except that the Commission may waive this requirement where other definite and assured provision is made for service access. Dead end alleys shall be avoided where possible, but if unavoidable, shall be provided with adequate turn-around facilities at the dead end, as determined by the Committee. (Ord. 849. Passed 3-12-73.)
