Corner Lots. In zoning districts requiring a front yard, there shall be a clear vision triangle on all corner lots. The triangle is an area bounded by the front and side street property lines and a line connecting them twenty-five (25) feet from their intersection. Within the triangle, the area between three (3) and eight (8) feet in height as measured from the top of the curb adjacent to the front yard shall be clear of vision obstructions. Trees may penetrate the clear area so long as there are no branches lower than eight (8) feet and the trunk, or trunks if there are multiple trees, do not exceed a combined width of four (4) feet. If no curb exists, the Public Works Director shall establish curb grade.

Driveways. In all zoning districts, there shall be a clear vision triangle on either side of a driveway intersecting with a public street right-of-way. The triangle is an area bounded by the street property line and the driveway and a line connecting them ten (10) feet from their intersection. When either the street or driveway is curvilinear, measurement shall be taken from the point of intersection using a ninety (90) degree angle which most closely aligns to both the driveway and street line. Within both triangles on either side of the driveway the area between three (3) and eight (8) feet in height as measured from the top of the curb adjacent to the driveway shall be clear of vision obstructions. Trees may penetrate the clear area so long as there are no branches lower than eight (8) feet and the trunk, or trunks if there are multiple trees, do not exceed a combined width of four (4) feet. If no curb exists, the City Engineer shall establish curb grade.

Sidewalks. In all zoning districts, no foliage or structural features shall extend into the cross visibility area between the surface of a sidewalk or public walkway and eight (8) feet in height as measured from the surface of the sidewalk or public walkway.

In addition to obstructions in A, B, and/or C above, the Director may require the removal of landscaping, structures or vehicles on any lot which in his opinion constitute a hazard to vehicular or pedestrian traffic.
