§ 11.22.010. Obstructing view prohibited.
The traffic engineer or the traffic engineer's designee shall determine, based on engineering judgment, the AASHTO publication, "A Policy on Geometric Design of Highways and Streets," (current edition), and this section, if a sight obstruction exists. Sight obstructions shall be prohibited at controlled and uncontrolled intersections of public streets.
Uncontrolled intersections. In all areas, on private or public property at any corner formed by intersecting streets, it is unlawful to install, set out, maintain, allow to remain, or allow the installation, setting out or maintenance of any sign, fence, hedge, shrubbery, natural growth or any other obstruction to view, regardless of nature, within the vision triangle as determined by a triangle whose sides are ninety feet measured along the centerlines of the approach streets from their point of intersection.
Controlled intersections. In all areas, on private or public property, at any corner formed by intersecting streets where the right-of-way is assigned to the major street and the minor street is stop-controlled, it is unlawful to install, set out, maintain, allow to remain, or allow the installation, setting out or maintenance of any sign, fence, hedge, shrubbery, natural growth or any other obstruction to view, regardless of nature, within the vision triangle. This vision triangle shall have its shorter side equal to one-half the major street width plus fifteen feet and the longer side equal to distance determined in the following tables:
