Corner lots or parcels in all residential zones and fences, walls, and retaining walls on property lines shall provide and maintain a vision clearance area. A “vision clearance area” is defined as a triangular area formed at a corner lot or parcel by the intersection of the street curb and a straight line joining said lines through points fifteen (15) feet back from their intersection. See Diagram “A” – 17.04.090.

The vision clearance area shall provide an area of unobstructed vision from three and one-half (3 1/2) feet to eight (8) feet above the top of the curb at the side of the vision clearance line intersection with the curb having the lower elevation. Natural topographic features, utility poles, and tree trunks are excluded from this requirement.
