Fences that are required by Federal or State law or regulation, or which are required by the City for public safety (e.g., temporary construction site fencing), are exempt from this section.
2.
Walls that are required by a mitigation measure and designed and approved through a tentative subdivision map, tentative parcel map, or site plan and architecture review for noise attenuation are exempt from this section.
B.
Fire Hazards. The Building Official shall not grant a Building Permit for the erection of any fence which will interfere with access in case of fire to buildings in the vicinity or which will constitute a hazard to street traffic or to pedestrians.

§ 19.82.030 Measurement of Fence and Wall Height.
A.
Fence and wall height shall be measured as the vertical distance between the lowest finished grade at the base of the fence and the top edge of the fence material. The finished grade shall be that as shown on the approved grading plan for the site at the time of initial development of the residential subdivision, multifamily development, or nonresidential development. In cases where a retaining wall does not require the approval of a grading plan, the finished grade shall be as determined by the Public Works Director.
B.
Retaining Walls. When a fence or wall is placed atop a retaining wall, the height shall be measured from the top of the retaining wall (see Figure 19.82.030-1 Measurement of Fence and Wall Height).

Fences may be located anywhere within the residential parcel, and shall be no taller than six feet, four feet in the front yard, and comply with the clear vision triangle requirements in subsection E below. Industrial and commercially zoned property may construct rear and side fencing to eight feet with an Administrative Use Permit, and meeting the clear vision triangle.
B.
Retaining Walls.
1.
Timing of Construction. Retaining walls shall only be constructed as part of an approved grading plan for the site at the time of initial development of the residential subdivision, multifamily development, or nonresidential development, as part of a roadway improvement project, or as part of the necessary stabilization of the soil for the primary intended use of the property as determined by the Public Works Director.
2.
Height Limit. The height of retaining walls shall be limited to that height reasonably necessary to support and retain the soil for the property.
C.
Residential Buffer.
1.
When any multiple-family residential dwelling greater than five units abuts a single-family residential dwelling, a six-foot-high solid masonry wall shall be required unless the Planning Commission approves an alternative upon architectural and site plan approval.
2.
Whenever new construction of any residential use abuts any educational institution, child care facility (with the exception of home-based child care), day nursery, small group care facility, nursing facility, convalescent facility, public utility substation, or any commercial, industrial, medical/professional office, or public/quasi-public use and/or district, a six-foot-high solid masonry wall shall be required unless the Planning Commission approves an alternative upon architectural and site plan review.

Open View Fencing. Open view fencing (a minimum of 50% transparency) is required in the following instances:
1.
All nonresidential fencing that is located within the front setback.
2.
When fencing is located adjacent to park, trail, or other open space area open to the public. This additional visibility is intended to increase the security of the open space area and the fenced-in property.
3.
Any portion of fencing over three feet in height located within the corner lot vision triangle.
E.
Vision Triangle.
1.
Vision triangles apply only to corner lots. The boundaries of a vision triangle are formed by drawing lines from the point of intersection of a lot's street corner property lines to points 30 feet along the two property lines and then connecting the two points with a straight line.

Residential Districts. No wall, fence, or hedge higher than three feet shall be erected or maintained on a corner lot in any residential district within the area called the vision triangle.
b.
Other Districts. In any district, other than a residential district, no wall, fence, hedge, or other obstruction to view shall be erected or maintained between three feet and eight feet above grade on any corner lot within the area called the vision triangle.
2.
Planting and Landscape Materials. Planting and landscape materials (except for street trees) shall not exceed three feet in height within the vision triangle area or if taller it shall have a minimum of 50% opacity to allow views through the landscaping material (opacity measurement also includes fencing materials).
