(a) Streets and alleys shall intersect one another at an angle as near to a right angle as is practicable considering topography of the area and previous adjacent layout.
(b) If an intersection must occur at an angle of less than 90 degrees, it shall comply with the standards in the American Association of State Highway and Transportation Officials (AASHTO) publication entitled “A Policy on Geometric design of Highways and Streets,” then in effect, or its replacement publication.
(2) Offsets. The minimum intersection offset shall be 100 feet on a local street, 200 feet on a collector street, and 400 feet on an arterial street unless adjusted through the process for adjustments to standards of EC 9.8030(12). Offsets shall be measured from the center lines of the two intersecting streets.
