9.31.010: PURPOSE AND APPLICABILITY: ¶

A. Purpose: The purpose of this chapter is to ensure that all development produces an environment of stable and desirable character that is harmonious with existing and future development, and protects the use and enjoyment of neighboring properties, consistent with the general plan.

B. Applicability: The standards of this chapter apply to all zones. These standards shall be considered in combination with the standards for each zone in article 2, "Zoning Districts And Development Standards", of this title. Where there may be a conflict, the standards specific to the zone or specific land use shall override these general standards. All structures, additions to structures, and uses shall conform to the standards of this chapter, as determined applicable by the director. (Ord. 254, 12-16-2014)

9.31.020: CLEAR SIGHT TRIANGLE: ¶

A. Visibility Required: To safeguard against vehicular, bicycle, and pedestrian collisions caused by visual obstructions at street and alley intersections, and at any point where a driveway intersects a street or alley, there shall be no visual obstruction within the clear sight triangle established in this section. Such space shall be kept free of buildings, structures, and landscaping that constitutes a visual obstruction. In hillside areas, clear sight triangle shall include such grading as may be necessary to provide for reasonable intersection visibility.

B. Clear Sight Triangle Described: The clear sight triangle is defined as:

The triangular shaped area on a corner lot, or at a point where a driveway intersects a street, formed by measuring the prescribed distance from the intersection of the front (or rear) and street side property lines at an intersecting street or alley, and connecting the lines diagonally across the property making a ninety degree (90°) triangle; and
The triangular shaped area on each side of any driveway intersecting a street or alley. FIGURE 3-1
