Sight triangle easements shall be required at the intersection of a street with another street and at the intersection of a street with a driveway providing ingress and/or egress to a nonresidential or multifamily residential development. Within the triangular area determined as provided in this section, no wall, fence, structure or other object shall be erected to a height in excess of 30 inches; no vehicle, object or other obstruction of a height in excess of 30 inches shall be permitted within the corner clearance area; and no hedge, shrub or other growth shall be maintained at a height in excess of 30 inches, except trees whose branches are trimmed to a height of at least seven feet above the curb level shall be permitted.
A. Such triangular area or sight triangle is defined as that area bounded by the intersecting street lines or driveway cartway lines and the straight line connecting sight points, one each located on the two intersecting street and/or driveway center lines.
(1) Sight points on driveways shall be 15 feet from the edge of pavement of the intersecting roadway.
(2) At the intersection of streets with no stop controls, the sight point for each street shall be 90 feet from the intersection of the center lines.
(3) In the instance of street intersections with stop controls for each street, the sight points shall be 75 feet from the intersection of the center lines.
(4) For partially stop-controlled intersections and for intersections of driveways with streets, the required dimension of the sight triangle shall depend upon the established speed limit of the uncontrolled street (or for future streets, the proposed design speed) in accordance with guidelines promulgated by the Institute of Traffic Engineers (ITE). Clear sight lines shall be provided, as follows, for a driver situated at 15 feet from the edge of pavement of the uncontrolled street or driveway:
| Speed Limit of Uncontrolled Street (miles per hour) | Minimum Required Sight Distance (feet) |
|---|
| 25 | 250 |
| 30 | 300 |
| 35 | 350 |
| 40 | 400 |
| 45 | 450 |
| 50 | 500 |
B. No object or other obstruction shall be so located along any straight or curved roadway as to reduce the line of sight along said road to less than 400 feet.
