(Code 2000, § 38-480; Ord. of 3-19-2002, Art. XVI, § 160)

(a)

Street intersection quadrant. In each quadrant of every public street intersection, there shall be a visual clearance triangle bounded by the street centerlines and a line connection point on them 300 feet from a Class A or Class B highway intersection 200 feet from a Class C, D, or E highway intersection.

(b)

Blocking of vision triangle. Nothing shall block the vision triangle from 2½ feet above the ground to ten feet above the ground. Open fences, telephone, telegraph, and power transmission poles, field and forest crops excepted.

(1)

At highway intersections with transitional widening. At all intersections of highways with other highways provided with transitional widening of pavement or surfacing, such transitional widening shall be considered as additional width and the setback lines on the side which is widened shall be increased by an amount equal to the width of the additional pavement.

(2)

Access driveways and road spacing.

a.

Access driveways to highways from abutting properties shall comply with the following requirements:

1.

Class A highway: No access driveways are allowed.

2.

Class B highway: A recommended minimum distance of 500 feet spacing of highway frontage between access driveways for separate land uses. A minimum distance of 500 feet spacing access driveways may be located to the right-of-way line of an intersecting highway. Discretion shall be granted to the D.O.T. to permit driveway at a lesser setback for safety reasons. Also subject to Wis. Admin. Code ch. Trans. 233.

3.

Class C highway: A recommended minimum of 300 feet spacing between access driveways; adjoining driveways permitted to accomplish same.

Discretion shall be granted to the county highway department to permit driveway at a lesser setback if justified by safety reasons.

4.

Class D and E highways: A recommended minimum of 200 feet spacing between access driveways; adjoining driveways permitted. To accomplish same, minimum distance of 200 feet spacing between access driveways and the right-of-way line of an intersecting Class A, B, or C highway, otherwise the spacing is the same as between two driveways. Discretion is granted to the towns to permit driveways at a lesser setback for safety reasons.

b.

Where there are two of more lots in less than 500 feet of frontage on a Class B highway, a service road of not less than 66 feet of right-of-way shall be provided across the entire frontage of each lot.
