17.20.170 - Purpose and intent.

The purpose and intent of the O zone is to provide the means necessary to implement the policies of the City's General Plan regarding open space and the land use designations "O" (open space), as delineated on the general plan map, and to designate zoning for those uses which are open in nature and thus contribute to the visual and spatial relief from continuous urban development. The "O" zone also serves to provide opportunities for outdoor recreation; preserve scenic qualities; protect sensitive or fragile environmental areas; preserve the capacity and water quality of the stormwater drainage system; and to provide pedestrian and bicycle transportation connections.

17.20.280 - Fences.

A. Purpose. The fence standards promote the positive benefits of fences without negatively impacting the community or endangering public or vehicle safety. Fences can create a sense of privacy, protect children and pets, provide separation from busy streets, and enhance the appearance of property by providing attractive landscape materials. The negative effects of fences can include the creation of street walls that inhibit police and community surveillance, decrease the sense of community, hinder emergency access, lessen solar access, hinder the safe movement of pedestrian and vehicles, and create an unattractive appearance. These standards are intended to promote the positive aspects of fences and to limit the negative ones.

B. Type of fences. The standards apply to walls, fences and screens of all types whether open, solid, wood, metal, wire, masonry, or other material.

C. Location. Fences may be 6 feet tall at the property line. A fence within 30 feet of a street lot line may not be more than 10 percent sight obscuring.

B. All buildings shall be designed to enclose or otherwise screen from view all rooftop mechanical equipment, ducts, tanks, etc., including solar systems. This requirement does not include windpowered turbines used for ventilation.

C. Where multistory buildings are to be utilized on lots abutting property in the R zone, such buildings shall be located or oriented in a manner which will minimize the visual intrusion into neighboring single-family property. (This may be accomplished by setting the building back from the abutting property line beyond the distance required by the yard, orienting the building in a manner which will not give a view into the back yard of their neighbors, or by other design consideration.)
