A. 
Visual clearance shall be provided in all zoning districts so that no fence, wall, architectural screen, earth mounding, landscaping or other feature obstructs the vision of a motor vehicle driver approaching any street, or driveway intersection. Whenever an intersection of a street(s) and/or driveway occurs, a triangular visibility area shall be created. Landscaping, fences, walls, earthen berms and other features within the triangular visibility area shall be designed so as to provide unobstructed cross-visibility at a level between twenty-four inches (24") and eight feet (8') above the ground. The triangular areas are defined as follows:
1. 
Minor street intersection (except a street intersecting onto an arterial, see below) or intersection of private driveway onto a public street - These areas shall have a triangular visibility area with two (2) sides of each triangle being a minimum of twenty-five feet (25') in length along the right-of-way lines (or along the driveway curb line and the street right-of-way line) from the point of the intersection, and the third side being a line connecting the ends of the other two (2) sides (see Illustration 5 [in Appendix B]).
2. 
Major street intersection - These areas shall have a triangular visibility area with two (2) sides of each triangle being a minimum of fifty feet (50') in length along the right-of-way lines from the point of the intersection, and the third side being a line connecting the ends of the other two (2) sides (see Illustration 5 [in Appendix B]).

A. 
Shrubs and plant materials that are typically less than twenty-four inches (24") in height at maturity may be located within sight visibility areas provided that they are kept maintained at a maximum height of twenty-four inches (24").
B. 
A limited number of single-trunked trees having a clear trunk (i.e., branching) height of at least eight feet (8') may be located within sight visibility areas provided that they are trimmed in such a manner that no limbs or foliage extend into the cross-visibility area defined above, and provided that they are spaced and positioned such that their trunks will not produce a visibility inhibiting, “picket-fence” effect when they attain mature size.
