The Council finds that in order to ensure public safety; provide efficient delivery of services by the City and others wishing to utilize wireless communication technologies; ensure the health, safety, and welfare of the population; provide for the regulation and administration and orderly location of antenna arrays and towers; and secure the rights of the City to regulate its public property and charge a reasonable fee for use of public property, it is necessary for the City to establish these uniform rules, regulations and policies.

   As used in this chapter:

      "Antenna" means a device, dish, or array used to transmit or receive telecommunication signals.

      "Communications" means the electronic, telephonic, or other high-tech transmission, reception, or exchange of data or information between or among points specified by the user of information of the user's choosing, without change in the form or content of the information as sent or received.

      "Communications tower" means a tower, pole, or similar structure which supports a communications antenna operated for commercial purposes above ground in a fixed location, whether free standing, guyed, or on a building.

      "Height" means the distance from ground level at the base of the tower or the base of any supporting structure to the top of the structure including any antenna(s) or other appurtenances.

   The Telecommunications Act of 1996 prohibits the City from establishing policies that discriminate against one or a group of providers in favor of another or another group of providers or potential providers. The following objectives shall be applied consistently to all telecommunications providers that request a location for their communication towers and antennas:

   1.   To minimize the overall number of towers located in the City, providers may be required to participate in collocation agreements.

   2.   To ensure that new towers will blend into their environment, providers will propose designs consistent with site characteristics.

   3.   To maximize safety new towers will be located away from population and employment centers and siting of new towers will include fall zone setbacks as specified herein.

   1.   Lease Required. No tower or antenna owner shall use any public property without first obtaining a lease from the City.

   2.   Insurance Required. The tower owner will produce proof of adequate liability insurance for potential damage that could reasonably be caused to City personnel, property and facilities by the location of the towers, antennas or facilities on City property.

   3.   Priorities. Priority of the use of City-owned land or structures will be given to the following entities in descending order of priority:

      A.   All functions of the City.

      B.   Public safety agencies that are not part of the City, including law enforcement, fire and ambulance services, and private entities with a public safety agreement with the City.

      C.   Other governmental agencies for uses which are not related to public safety.

      D.   Entities providing communication services, including cellular, personal communication services, specialized mobilized radio, enhanced specialized mobilized radio, paging and similar services that are marketed to the general public for business and/or personal use.

   4.   Placement of Facilities. The placement and maintenance of communication towers, antennas, and facilities on City-owned sites, such as water towers and parks, will be considered when the following requirements are met:

      A.   Water Tower or Reservoir Sites. The City's water tower and reservoir represent a large public investment in water pressure stabilization and peak capacity reserves, and its protection is of prime importance. For that reason, the placement of communication towers or antennas on water towers or reservoir sites will be allowed only when the following requirements are found by the City to be met:

         (1)   The owner must have approval from the City each time access to any equipment mounted on a water tower is desired. This will minimize the risk of contamination to the water supply.

         (2)   There is sufficient room on the structure and/or the grounds to accommodate the owner's facilities.

         (3)   The presence of the facility will not substantially increase the water tower or reservoir maintenance costs to the City.

         (4)   The presence of the facility will not be harmful to the health or safety of workers maintaining the water tower or reservoir.

      B.   Parks. The presence of communications towers, antennas, or similar facilities represents a potential conflict with the purpose of City-owned parks and recreational facilities. Communications towers and antennas will be considered only in park facilities that are remote from places where people regularly live, work or gather and large enough to accommodate the use without significant impact to adjacent property owners, after recommendation of the Parks and Recreation Commission and approval of the Council.

   1.   A tower must be set back:

      A.   From all ID or residential lot lines a distance equal to or greater than the tower height.

      B.   From lot lines of all other districts a distance equal to or greater than the height of the tower; however, if the tower manufacturer certifies that the tower is designed to collapse within a smaller area, the setbacks may be reduced consistent with said certification but shall in no case be less than 50% of the height of the tower. Use of the tower manufacturer's certification to reduce the set back as described herein is subject to the review and approval of the City Engineer.

   2.   Any communications facilities located on the roof of an antenna support structure must be set back at least one foot from the edge of the roof of the structure. This setback requirement shall not apply to communications facilities located above the roof of the structure, if the facilities are:

      A.   Appropriately screened from view through the use of panels, walls, fences or other screening techniques approved by the City; or

      B.   Camouflaged antennas that are mounted to the exterior of the antenna support structures below the roof but do not protrude more than 24 inches from the side of such an antenna support structure.

   3.   The following height conditions apply:

      A.   Commercial and Public Use Districts. Freestanding or guyed tower with a height not exceeding 200 feet.

      B.   Industrial Districts. Freestanding or guyed tower with height not exceeding 360 feet.

   No equipment shall be operated at towers or telecommunications facilities so as to produce noise in excess of applicable standards under WAC173-60, except during emergencies or periodic routine maintenance which requires the use of a backup generator where the noise standards may be exceeded temporarily.

   In the event the use of any communications tower has been discontinued for a period of 180 consecutive days, the tower shall be deemed to be abandoned. Determination of the date of abandonment shall be made by the City Administrator, who shall have the right to request documentation and/or affidavits from the communications tower owner regarding the issue of tower usage. At 181 days after the date of abandonment, without reactivating or upon completion of dismantling or removal, any City approval for the tower shall automatically expire. Upon abandonment, the owner of the tower shall have an additional 90 days within which to reactivate the use of the tower, transfer the tower to another owner who makes actual use of the tower within the 90 days, or dismantle and remove the tower. If not done within this 90 day period, the City may dismantle and remove the tower with all costs assessed to the tower owner.

   The following procedures shall apply to all communication tower or antenna facilities on public or private property.

   1.   Submission Materials and Basis for Approval or Denial. The following information shall be submitted to the City Planning Director and will be utilized by the City in review of the application, except that items C, I and K may be waived in the City's discretion if the antenna is proposed to be located on a tower owned by the City or constructed on City property and intended to be used for colocation of antennas:
