When an access way intersects a public right-of-way, or when a subject property abuts the intersection of at least two public rights-of-way, all landscaping within the triangular areas described herein shall provide unobstructed cross-visibility at a level between three and six vertical feet; provided, however, that trees and other plant material shall have their limbs and/or foliage trimmed in such a manner that no visual impediment exists within the cross-visibility area; and further provided, that any trees or vegetation are located in such a manner as to create no traffic hazard. Landscaping, except required turf grass or ground cover, shall not be located closer than three feet from the edge of any accessway pavement. The triangular areas and clearances required are established in the street and utility standards adopted by reference in SMC 14.14.010 and include Section 2B.160, Sight Obstruction, and Diagram T-1, Sight Obstruction for Stop or Yield Controlled Intersections and Uncontrolled Intersections.
