B. Large Satellite Dish Antenna – Development Standards. The following minimum standards apply to all antennas:

1. Siting on Lot. Large satellite dish antennas shall be sited in the rear yard as a first order of preference. If the applicant demonstrates that reception is not available in this location, the second order of preference for siting shall be the side yard. If the applicant demonstrates that reception is not available in this location, the third order of preference shall be the front yard. Finally, if reception is not available in any other location, the satellite dish antenna may be located on or attached to a roof, pursuant to the special exception procedures in GHMC 17.61.100.

2. Height and Size. Antennas, antenna mountings and large satellite dishes shall be no taller than the minimum required for the purposes of obtaining an obstruction-free reception window. Large satellite dish antennas shall not exceed 12 feet in diameter and 15 feet in height, including their bases. Height shall be measured from existing grade.

3. Color. To the extent technically feasible, specific paint colors may be required to allow the antenna or large satellite dish and mounting structures to blend better with the surroundings.

4. Screening, Landscaping. Screening of all large satellite dish antennas may be required with one or a combination of the following methods: fencing, walls, landscaping, structures or topography which will block the view of the antenna as much as practicable from any street and from the yards and main floor living areas of residential properties within approximately 500 feet. Screening may be located anywhere between the antenna and the abovementioned viewpoints. A dense vegetative screen (pursuant to GHMC 17.04.269) shall be provided for large satellite dish antennas that are visible from any portion of the right-of-way. Landscaping installed for the purposes of screening shall be maintained in healthy condition.

5. Signs Prohibited. Satellite dish antennas shall not be used for the purposes of signage or message display of any kind.

6. IBC Conformance. Construction plans and final construction of the mounting bases of all large satellite dish antennas shall be in accordance with the requirements established in the latest edition of the International Building Code adopted by the city.

7. Type of Dish. Aluminum mesh dishes should be used, as practicable, instead of a solid fiberglass type large satellite dish antenna.

8. Number of Dishes Allowed. Only one large dish satellite antenna shall be allowed on each residentially zoned property.

C. Amateur Radio Towers – Development Standards. The following minimum standards apply to amateur radio towers:

1. Siting on Lot. Amateur radio towers may be ground- or roof-mounted; however, ground-mounted towers must be located at a point farthest from lot lines as feasible, or the point farthest from residential structures on abutting properties.

2. Height and Size. The height of a ground-mounted tower may not exceed 65 feet unless an applicant demonstrates physical obstructions to reception. Telescoping towers may exceed the 65-foot height limit only when extended and operating. The combined structure of a roof-mounted tower and antenna shall not exceed a height of 25 feet above the existing roofline.

3. Color. To the extent technically feasible and in compliance with safety regulations, specific paint colors may be required to allow the tower to blend better with its setting.

4. Screening, Landscaping. Screening of the bases of ground-mounted amateur radio towers shall be provided with one or a combination of the following methods: fencing, walls, landscaping, structures, and/or topography which will block the view of the antenna as much as practicable from any street and from the yards and main floor living areas of residential properties within approximately 500 feet of the tower. Screening may be located anywhere between the base and the abovementioned viewpoints. Landscaping for the purposes of screening shall be maintained in a healthy condition. Bases of amateur radio towers shall be solidly screened by a view-obscuring fence, wall, or evergreen plantings at least six feet in height.

5. Signs Prohibited. No signs shall be placed or posted on amateur radio towers.

6. IBC Conformance. Construction plans and final construction of the mounting bases and towers of amateur radio towers covered by this section shall meet the structural design requirements of this section and shall be in accordance with the requirements established in the International Building Code as adopted by the city.

D. Wireless Communication Facilities – Development Standards. The following standards shall be applied to all wireless communication facilities, such as antenna and equipment shelters, exclusive of the broadcast and relay tower and shall not apply to small wireless facilities (for small wireless facility design and concealment standards see GHMC 17.61.035). Wireless monopoles, lattice, and guy towers are regulated by the subsections that govern broadcast and relay towers, GHMC 17.61.090(E)(2) through (E)(7).

1. Siting on Lot. No wireless communications facilities shall be located within required building setback areas unless it is demonstrated that locating the proposed facility within the required setback area will take advantage of an existing natural or artificial feature to conceal the facility or minimize its visual impacts.

2. Height and Size. The combined antenna and supporting structure shall not extend more than 15 feet above the existing or proposed roof structure.

3. Color, Screening, Landscaping.

a. Wireless communication antennas installed on existing buildings shall be screened or camouflaged to the greatest practicable extent by use of shelters, compatible materials, location, color, and/or other visual mitigation techniques to reduce visibility of the antenna as viewed from any street or residential property. The antenna shall be visually concealed utilizing color and compatible material to camouflage the facility to the greatest extent feasible.

b. Screening of wireless communications facilities shall be provided with one or a combination of the following materials: fencing, walls, landscaping, structures, or topography which will block the view of the antenna and equipment shelter as much as practicable from any street and from the yards and main floor living areas of residential properties within 500 feet. Screening may be located anywhere between the base and the abovementioned viewpoints.

c. Landscaping for the purposes of screening the wireless communications facilities shall be maintained in a healthy condition.

d. Any fencing required for security shall meet the screening standards of the city’s design guidelines.

4. Signs Prohibited. No wireless equipment shall be used for the purposes of signage or message display of any kind.

5. Conform to IBC. Wireless communication facilities shall comply with all applicable IBC requirements.

6. Abandonment, Disrepair. A wireless communication facility shall be removed by the facility owner within 12 months of the date it ceases to be operational or if the facility falls into disrepair and is not maintained. Disrepair includes structural features, paint, landscaping, or general lack of maintenance which could result in safety or visual impacts.

7. Colocation. Placement of a freestanding wireless communication facility may be denied if placement of the antenna on an existing structure can accommodate the applicant’s/operator’s communications needs. The applicant shall also comply with the colocation requirements of GHMC 17.61.020(C). The colocation of a proposed antenna on an existing broadcast and relay tower or placement on an existing structure shall be explored and documented by the applicant/operator in order to show that reasonable efforts were made to identify alternate locations.

8. Equipment Shelters.

a. Limit on Area. Associated aboveground equipment shelters shall be minimized, and shall not exceed 240 square feet (e.g., 12 feet by 20 feet) unless operators can demonstrate that more space is needed.

b. Color. Shelters shall be painted a color that matches existing structures or the surrounding landscape.

c. Materials. The use of concrete or concrete aggregate shelters is not allowed.

d. Screening, Landscaping. A dense vegetative screen shall be created around the perimeter of the shelter.

e. Undergrounding. Operators shall consider undergrounding equipment if technically feasible or placing equipment within existing structures.

f. IBC Conformance. Equipment shelters shall comply with all IBC requirements, but may be exempt from building envelope insulation requirements. (See RCW 19.27A.027.)

E. Broadcast and Relay Towers – Development Standards. Broadcast and relay towers are not permitted in any residential, waterfront district and downtown business districts. (Ord. 1419 § 3, 2019; Ord. 771 § 12, 1997. Formerly 17.61.030).
