A. Clear Vision Areas: A clear vision area shall be maintained on the corners of all property at the intersection of two (2) streets or a street and a railroad.
1. A clear vision area shall consist of a triangular area, two (2) sides of which are lot lines measured from the corner intersection of the street lot lines for a distance specified in this subsection A, or where the lot lines have rounded corners, the lot lines extended in a straight line to a point of intersection and so measured and the third side of which is a line across the corner of the lot joining the nonintersecting ends of the other two (2) sides.
2. A clear vision area shall contain no planting, fence, wall, structure or temporary or permanent obstruction exceeding two and one-half feet (21/2') in height, measured from the top of the curb or, where no curb exists, from the established street centerline grade; except, that trees exceeding this height may be located in this area, provided all branches and foliage are removed to a height of eight feet (8') above the grade.
3. The following measurements shall establish clear vision areas:
a. In a residential zone, the minimum distance shall be thirty feet (30') or, at intersections including an alley, ten feet (10').
b. In all other zones where yards are required, the minimum distance shall be fifteen feet (15') or at intersections including an alley, ten feet (10'); except, that when the angle of intersection between streets other than an alley is less than thirty degrees (30°), the distance shall be twenty five feet (25').
c. Where no yards are required, the minimum distance shall be as in subsection A3b of this section and buildings may be constructed within the clear vision area; providing, that any portion of the structure within the clear vision area is more than eight feet (8') above the top of the curb or street centerline grade and is supported by not more than two (2) columns not more than eight inches (8") in diameter.
B. Ground Cover Requirements: Any property in an R-1, R-2, R-3, DD or C zone shall be paved or planted with ground cover, trees and bushes or landscaped so as to prevent any dust blowing from the property. Such plantings shall be in place within six (6) months after completion of the structure. (Ord. 542, 8-11-2003)
