(A) Cul-de-sacs. Cul-de-sac streets in Single-Family Residential Districts shall not be more than 600 feet in length, measured along their center lines from the streets of origin to the ends of their right-of-way, or may be longer than 600 feet, provided not more than 20 lots abut upon their right-of-way lines. Each cul-de-sac shall have a terminus of nearly circular shape with a minimum diameter of 120 feet. The terminus shall be connected with each right-of-way line of the approach segment of the street by a reverse curvation having a radius of not less than 30 feet.
(B) Street curves.
(1) Curves in streets shall be permitted; provided, no curve shall be greater than that approved by the Village Engineer as reasonably safe for traffic at the particular location of the curve, but with a radius of not less than:
Primary and collector streets
(2) Minimum length of tangents between reverse curves:
(3) Different connecting street gradients shall be connected with vertical curves. Minimum length in feet of curves shall not be less than:
Minor and cul-de-sac streets
20 feet for each 1% algebraic difference of grade but in no case less than 100 feet
Primary and collector streets
30 feet for each 1% algebraic difference of grade but in no case less than 100 feet
(C) Street jogs. Street jogs with center line offsets of less than 125 feet shall not be permitted if the same can be reasonably avoided.
(D) Minor streets. Minor streets shall be so aligned that their use by through traffic will be discouraged.
(E) Intersections. Street intersections and confluences shall be planned in a manner that will provide safe and efficient traffic flow. Streets shall intersect at or near right angles, and an intersection of more than two streets shall be avoided unless specific conditions of designs indicate otherwise. No street shall intersect any other at less than 60 degrees.
(F) Half streets. Half streets shall be prohibited wherever possible. Wherever an existing or dedicated half street is adjacent to a tract to be subdivided, the other half street shall be platted within the tract. A half street, where included, shall be graded at one level, and the regarding or new construction on any half street shall conform to the grade and pavement of the adjacent street. Where the adjacent half street is unimproved, the developer of the plat being subdivided shall complete the construction of the unimproved section to grade with stone shoulder a minimum width of ten feet.
(G) Access ways.
(1) Provisions shall be made for vehicular and pedestrian access to residential property abutting limited access roads either:
(a) By providing marginal access streets; or
(b) By backing lots to the thoroughfare and providing access by a collector, minor or cul-de-sac street one lot depth removed and with a visual barrier established in a nonaccess reservation strip along the rear property line (abutting the thoroughfare).
(2) These standards are established for the purpose of providing protection to residential properties and to separate through and local traffic.
(H) Street grades. Longitudinal gradients of streets shall be at least 0.4% and not exceed the following:
(I) Sidewalks. Sidewalks of minimum five-foot width and five-inch thickness, constructed in accordance with State Division of Highways Department of Public Works standards, shall be required on all subdivisions, in accordance with the requirements set forth by the village specifying location and type of material as indicated by the Village Standards, Drawing No. 1.
(J) Street arrangement: Streets shall be related appropriately to the topography and all streets shall be arranged so as to obtain as many as possible of the building sites at or above the grades of the street. Grades of streets shall conform as closely as possible with the original topography. Topography permitting a combination of street grade curves shall be avoided.
(K) Side streets. Side streets shall be completed to the back lot line of adjacent developed lots.
