Commercial, Office, Industrial, Public Utility Aerials.

Aerials intended for commercial, office, industrial and public use are prohibited on residentially zoned and used properties, except the RHS zoning district. Aerials may also be allowed on common-interest areas of residential or mixeduse planned development zoned properties subject to homeowner association approval, in accord with the permit requirements of Section 19.136.080.

19.136.060 Design and Site Review. 

For aerials requiring discretionary review, the primary review objectives are to ensure the goals of Section 19.136.010 are met and to blend the design of the aerial into the surrounding environment, or site the aerial in such a manner to minimize the visual intrusiveness of the structure or artistically enhance the appearance of the aerial. This review may include, but not be limited to, the following criteria:

Gaps in coverage that would create emergency communication problems;

Viability of alternative locations, such as commercial, industrial, office, and public building sites;

Method of antenna-mounting, that is, wall-mounting, roof-mounting or a freestanding structure;

Colors, materials and textures to integrate the aerial into the surrounding environment or building;

Landscaping to screen the aerial;

Proximity and visibility of the aerial to residential properties and public rights-ofway;

Dispersal of aerial locations to avoid visual clutter;

Concentration of aerial locations to avoid visual clutter;

Opportunities for collocation of aerials on existing masts and towers where visual intrusiveness is reduced;

Design of the building or enclosure, which houses the related base equipment and its compatibility with the adjoining building architecture;

Opportunities to develop context-appropriate, artistically enhanced aerial designs; Screening of highly visible rooftop-mounted aerials; and

Balancing of aesthetic concerns with the need to provide a functional communications system.

19.136.070 Application Requirements. 

In addition to the standard application requirements in Chapter 19.12, the applicant may be required to provide the following additional materials:

If more than one aerial is planned in the City within a year by a single communication service provider, a master plan shall be prepared of all facilities that can be reasonably foreseen, showing the proposed aerial sites and existing commercial, office, industrial and public utility aerial locations within a one mile radius of the proposed sites. The purpose of this requirement is to identify opportunities for clustering, dispersal and collocation of aerials to reduce visual intrusiveness;

Erection of a mock aerial, computer simulation or sight-line elevations for all aerials to help assess the visual effects; and

Documentation that the technology and usage of that technology meets Federal Communications Commission adopted safety standards.
