(A) Not more than two streets shall intersect at any one point.
(B) 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 degrees. An oblique street shall be curved approaching an intersection and shall be approximately at right angles with the intersection for at least 100 feet therefrom.
(C) Proposed new intersections along one side of an existing street shall, whenever practicable, coincide with any existing intersections on the opposite side of the street. Except where terrain does not permit, street intersection jogs with centerline offsets of less than 150 feet shall not be permitted, except where the intersected street has divided lanes without median breaks at either intersection. Intersections involving collector or minor arterial streets should be at least 1,000 feet apart.
(D) Radii-returns at intersections shall be made concentric and shall be rounded by a radius of not less than 25 feet at the right-of-way line and less than 30 feet at the back of curb line.
(E) All streets (including intersections) shall be built in such a way that the cross-slopes thereon do not exceed 3%.
(F) The corner sight distance for streets should be a minimum of 300 feet and desirably should be 400 feet or more. For local streets the minimum corner sight distance should be a minimum of 200 feet and desirably should be 300 feet or more. In order to maintain the minimum distance, restrictions on height of embankment, locations of buildings and screening fences may be necessary. Any landscaping in the sight distance triangle should be low growing, i.e., two feet above pavement level.
(G) A flat grade shall be provided at intersections whenever practical; in hilly terrain, an area with a 3% slope or less for a distance of 75 feet from the center of the cross street shall be provided at the approach to the intersection.
(H) Where a development traffic study indicates a signal is required, or any governmental body directs a developer to install traffic signals, the poles, mast arms, signal heads and all associated fittings, connections, nuts and bolts shall be black in color. (All parts shall be galvanized per I.D.O.T. standard, primed per manufacturers recommendations and then painted black.)
