4.2.130 Vision Clearance Area.
(A) All lots or parcels must maintain a Vision Clearance Area to provide sight distance for approaching traffic. Vision clearance areas must be shown on Site Plans for applicable land use applications.
(B) No screens, plantings, or other physical obstructions are permitted between 2½ and 8 feet above the established height of the curb in the Vision Clearance Area.
Items associated with utilities or publicly-owned structures—for example, poles, and signs, and existing street trees—may be permitted.
(C) The Vision Clearance Area must be in the shape of a triangle. Two sides of the triangle must be property lines or a property line and edge of driveway for a distance specified in this subsection. Where the property lines or driveway edge have rounded corners, they are measured by extending them in a straight line to a point of intersection. The third side of the triangle is a line across the corner of the lot or parcel joining the non-intersecting ends of the other 2 sides. The following measurements establish the Vision Clearance Area:
Table 4.2.5
Type of Intersection |
Measurement Along Each Property Line |
Any Street |
20 feet |
Any Alley |
15 feet |
Any Driveway |
10 feet |
The Director may require that the Vision Clearance Area be increased to be consistent with the sight distance standards and requirements in the AASHTO “A Policy on Geometric Designs of Highways and Streets” when safety concerns warrant the increase. (6443; 6412)
