§ 424. Clear View of Intersection Streets.

To provide a clear view of intersecting streets to the motorist, there shall be a triangular area of clear vision formed by the two intersecting streets. The size of this triangular area is a function of traffic volume and speed and is depicted for right-angle intersections in Figure 8. At oblique intersections, in which two roads form an angle of 60 degrees or less, required clear areas shall be determined by the City Engineer, based on design criteria set forth in the most recent edition of A Policy on Geometric Design of Highways and Streets, prepared by the American Association of State Highway and Transportation Officials (AASHTO).

Where, in the opinion of the Planning Commission, there are unusual and/or specific circumstances relating to a street intersection such that the application of Figure 8 may not be appropriate, the intersection shall be referred to the City Engineer who shall recommend a triangular area of clear vision using the standards contained in the current edition of the Manual of Uniform Traffic Control Devices.

On any portion of a lot that lies within the triangular area defined according to this section, nothing shall be erected, planted, placed, or allowed to grow in such a manner as materially to impede vision between a height of two and one half (2.5) feet and ten (10) feet above the grade at the intersection of the street center lines.
