Whenever the Traffic Engineer finds that any hedge, shrubbery, tree or fence or other obstruction, growing, erected or maintained in a parkway or on private property in the setback area obstructs the view of any driveway or intersection, or any traffic upon the streets approaching such driveway or intersection, he or she shall cause the hedge, shrubbery, tree, fence or other obstruction to be immediately removed or reduced in height. Such hazards may include any structure, fence, landscaping or other obstructions more than two feet in height above the level of the sidewalk or ground elevation, whichever is higher, in an area called a vision triangle as specified below, except that trees may be allowed when no foliage is closer to the ground than seven and one-half feet and fences that are at least 50% open shall be permitted up to three feet in height.
A. At street intersections, the boundaries of the vision triangle are formed by measuring along the curblines from the projected intersection a distance of 50 feet and then connecting the two points with a straight line.
B. At driveway entrances, the boundaries of the vision triangle are formed by measuring along the side of the paved driveway and along the street right-of-way line from their intersection a distance as specified below and then connecting the two points with a straight line:
1. Not less than 10 feet for local streets;
2. Not less than 15 feet for collector streets;
3. Not less than 20 feet for arterial streets
