E. 
Encourage users of towers and antennas to locate them, to the extent possible, in areas where the adverse impact on the community is minimal, now and in the future;
F. 
Encourage users of towers and antennas to configure them in a way that minimizes the adverse visual impact of the towers and antennas through careful design siting, landscape screening, and innovative camouflaging techniques;
G. 
Enhance the ability of providers of wireless telecommunications services to provide such services to the community quickly, effectively and efficiently;
H. 
Consider the public health and safety of wireless telecommunication towers;
I. 
Avoid potential damage to adjacent properties from tower failure through engineering and careful siting of tower structures;
J. 
Retain local responsibility for and control over the use of the public right-of-way to protect citizens and enhance the quality of their lives;
K. 
Create and preserve telecommunication facilities that will serve as an important and effective part of the city's emergency response network; and
L. 
Promote fair and effective wireless telecommunication services and ensure that a broad range of competitive telecommunications services with high quality telecommunications infrastructure are available to serve the community.

Proximity of the tower to residential structures and residential district boundaries;
c. 
Nature of uses on adjacent and nearby properties;
d. 
Surrounding topography;
e. 
Surrounding tree coverage and foliage;
f. 
Design of the tower, with particular reference to design characteristics that have the effect of reducing or eliminating visual obtrusiveness;
g. 
Proposed ingress and egress;
h. 
Availability of suitable existing towers, other structures, or alternative technologies not requiring the use of towers or structures, as discussed in subsection (B)(3) of this section; and
i. 
Impact on view sheds in the city.
3. 
Availability of Suitable Existing Towers, Other Structures, or Alternative Technology. No new tower shall be permitted unless the applicant demonstrates to the reasonable satisfaction of the planning commission that no existing tower, structure or alternative technology that does not require the use of towers or structures can accommodate the applicant's proposed antenna. An applicant shall submit information required by this section and/or requested by the planning commission related to the availability of suitable existing towers, other structures or alternative technology. Evidence submitted to demonstrate that no existing tower, structure or alterative technology can accommodate the applicant's proposed antenna may consist of any of the following:
a. 
No existing towers or structures are located within the geographic area which meet the applicant's engineering requirements.
b. 
Existing towers or structures are not of sufficient height to meet the applicant's engineering requirements.
c. 
Existing towers or structures do not have sufficient structural strength to support the applicant's proposed antenna and related equipment.
d. 
The applicant's proposed antenna would cause electromagnetic interference with the antenna on the existing towers or structures, or the antenna on the existing towers or structures would cause interference with the applicant's proposed antenna.
e. 
The fees, costs, or contractual provisions required by the owner in order to share an existing tower or structure or to adapt an existing tower or structure for sharing are unreasonable. Costs exceeding the expense of constructing a new tower facility are presumed to be unreasonable.
f. 
The applicant demonstrates that there are other limiting factors that render existing towers and structures unsuitable.
g. 
The applicant demonstrates that an alternative technology that does not require the use of towers or structures, such as a cable microcell network using multiple low-powered transmitters/receivers attached to a wireline system, is unsuitable. Costs of alternative technology that exceed new tower or antenna development shall not be presumed to render the technology unsuitable.
4. 
Setback Requirements. The following setback requirements shall apply to all towers for which a conditional use permit is required; provided, however, that the planning commission may alter the standard setback requirements if the goals of this section would be better served thereby:
a. 
Towers must be set back a distance equal to at least 75 percent of the height of the tower from any adjoining lot line. The setback may be reduced by the applicant submitting an analysis to justify the reduction for review by the approving authority.
b. 
Guys and accessory buildings must satisfy the minimum land use district setback requirements.
c. 
Tower facilities shall be set back a distance of 200 feet from any residential zoned property.
5. 
Separation Requirements. The following separation requirements shall apply to all towers and antennas for which a conditional use permit is required; provided, however, that the planning commission may alter the standard separation requirements if the goals of this section would be better served thereby.
a. 
No tower or tower farm shall be sited closer than 1,000 feet from an existing, or otherwise approved, facility, unless the new facility is a collocated facility, in which case the minimum separation shall be 750 feet. However, where the collocated facility is less than 75 feet in height, the minimum separation shall be 500 feet.
b. 
Separation distances between towers shall be applicable for and measured between the proposed tower and pre-existing towers. The separation distances shall be measured by drawing or following a straight line between the base of the existing tower and the proposed base, pursuant to a site plan, of the proposed tower.
6. 
Height. The planning commission may consider approval of towers proposed to exceed the maximum height limit of the underlying land use district as part of its review of a conditional use permit application. In approving the height of a tower, the planning commission shall give consideration to the potential for collocation and whether the requirements of the applicant as demonstrated in the site analysis indicate a need for an increased height.
7. 
Screening. Towers and/or associated facilities shall be enclosed by security fencing and screened with material not less than six feet in height and shall also be equipped with an appropriate anti-climbing device and/or landscape material; provided, however, that the planning commission may waive such requirements, as it deems appropriate.
8. 
Landscaping. The following requirements shall govern the landscaping surrounding towers for which a conditional use permit is required; provided, however, that the planning commission may waive such requirements if the goals of this section would be better served thereby.
a. 
Tower facilities shall be screened with materials that effectively screen and buffer the view of the tower compound from adjacent properties.
b. 
In locations where the visual impact of the tower would be minimal, the landscaping requirement may be reduced or waived. However, any cabinet or other structure shall be screened as approved by the city.
c. 
Existing mature tree growth and natural land forms on the site shall be preserved to the maximum extent possible. In some cases, such as towers sited on large, wooded lots, natural growth around the property perimeter may be sufficient buffer.
9. 
Performance Standards. No wireless telecommunication facility shall interfere with the public safety radio communications system, including, but not limited to, the 800 MHz trunking system. If such facility is found to interfere with the public safety radio system, it shall immediately cease operations until such time as the interference is resolved to the satisfaction of the city.
10. 
Temporary Facilities in Connection with Permanent, Approved Facilities. A temporary wireless communication facility may be deployed subject to approval by the community development director and meets the following:
a. 
A permanent wireless communication facility has been approved for the property in question.

Pre-Existing Towers. Installed towers preexisting the effective date of the ordinance codified in this section shall be allowed to continue their usage as they presently exist.

Rebuilding Damaged or Destroyed Nonconforming Towers or Antennas.

The type, height, and location of the tower on-site shall be of the same type and intensity as the original facility approval. Building permits to rebuild the facility shall comply with the then applicable building codes and shall be obtained within 180 days from the date the facility is damaged or destroyed. If no permit is obtained or if said permit expires, the tower or antenna shall be deemed abandoned as specified in HMC § 16.45.120.
