RE: File #14-104126-00-UP; PROCESS I `DIRECTOR'S APPROVAL'
Verizon Wireless — SEA SW 3201h St., 2105 SW 320'h Street, Federal Way
Dear Ms. Zavales:
The Community and Economic Development Department has received your Process I Master Land Use
(MLU) application to create a new equipment enclosure for an above -ground diesel generator for
emergency back-up. The Process I MLU application is hereby conditionally approved pursuant to
conclusions based on findings made by the department's Planning Division.
CONCLUSIONS
Various sections of the zoning and development code indicate that certain developments, activities, or
uses are permitted only if approved using Process I — Director's Approval. Based on the findings below,
the proposed improvements to the developed site meet the following Process I approval criteria and land
use review thresholds of Federal Way Revised Code (FWRC) 19.15.030 and 19.55.020:
1. The proposed improvements are consistent with applicable chapters of FWRC Title 19 including,
but not limited to: Permits and Review Processes; Process I — Director's Approval; Personal
Wireless Service Facilities; and Professional Office (PO).
2. The health, safety, and welfare of the citizens of the city are preserved.
3. The proposal is a minor improvement, modification, or addition to a site that is exempt from
SEPA review.
FINDINGS
The zoning for the site is Professional Office (PO). The existing Verizon Wireless Personal Wireless
Service Facility (PWSF) is an allowed use in the PO zone. The PWSF antennas are mounted to an
existing Puget Sound Energy (PSE) utility pole located in the right-of-way, and ground equipment on a
cement pad on an adjacent parcel of land. No work is proposed to the pole or antennas. The generator
addition was reviewed as an administrative land use process pursuant to Federal Way Revised Code
(FWRC) Chapter 19.55, `Process I — Director's Approval'.
The proposed diesel generator is to be installed on a new 4' x 8' concrete slab at grade, next to the
existing fenced equipment enclosure. An 8-foot-tall cedar fence with gate creates a solid screen of the
generator and associated equipment. The fence incorporates sound attenuation materials and noise
barriers for sound absorption. The increase of fence height of 8 feet is also proposed to mitigate any
negative noise impacts to the multi -family residential zone to the north, and to meet FWRC 7.10.050,
which adopts by reference the maximum environmental noise levels per Washington Administrative Code
(WAC) 173.60.
Ms. Zavales
September 11, 2014

The generator and fence meets the required 20-foot setback from all property lines. Additionally, five-foot
landscape buffer, consisting of arborvitae shrubs, is proposed around the enclosure. However, per FWRC
19.210.050, at a minimum, a five-foot type III landscaping area is required around the facility. Type III
landscaping is a visual buffer, including a mixture of evergreen and deciduous trees interspersed with
large shrubs and groundcover. Prior to building permit approval, a revised landscape plan will be
required, depicting Type III landscaping in the proposed 5-foot landscaped buffer area.
The generator does not reduce the amount of required landscaping, buffering, open space, or public areas;
and does not alter pedestrian connections, utilities, or easements.
CONDITION OF APPROVAL
Prior to building permit approval, a revised landscape plan must be submitted depicting Type III
landscaping (shrubs, trees, and groundcover) in the 5-foot landscape buffer area.
ADDITIONAL PERMIT ISSUANCE REQUIRED
Prior to any site work, the applicant shall obtain a building and electrical permit from the city's Building
Department. For further information regarding the above -mentioned permits; please contact the
Department's Permit Center at periTiitcenter@cilyoff-ederalway.com or 253-835-2607.
APPEALS
The effective date of this decision is September 14, 2014, or three days from the date of this letter.
Pursuant to FWRC 19.55.050, any person who received notice of the administrative decision may appeal
this decision to the Federal Way Hearing Examiner by September 30, 2014. Any appeal must be in the
form of a letter delivered to the Department of Community and Economic Development with the
established fee. The appeal letter must contain a clear reference to the matter being appealed and a
statement of the alleged errors in the Director's decision, including the identification of specific findings
and conclusions made by the Director disputed by the person filing.
In that you are the only party of record, your appeal period is waived (assuming you do not wish to appeal
this decision). Waiver of the right to appeal does not affect the effective date of this decision.
CLOSING
This land use decision does not waive compliance with future City of Federal Way codes, policies, and
standards relating to this development. This Process I approval does not constitute approval of a building
or electrical permit. If you have any questions regarding this decision, please contact Becky Chapin,
Associate Planner, at 253-835-2641, or becky.chapin@cityoffederalway.com.

Subject: Verizon SEA SW 320th (Generator)
Hello Ann,
My name is Bert White and I work for Lynx Consulting. We're currently working on a project for Verizon Wireless called
SEA SW 3201h. On this site, Verizon Wireless is proposing the addition of a 30kW diesel generator. Through Becky Chapin,
I received the following comment from the Public Works Department.
" Please have the applicant explain how they will be meeting storm water source control requirements in accordance
with the iCmQ County Stormwater Pollution Prevention Manual."
In review of the KC SPPM, it seems that the section in concern would be the "Storage of Liquid Materials in Stationary
Tanks" (section III subgroup A-2). Please see the following notes regarding BMP's being implemented in regards to this
section of the code.
BMP1
o This BMP is being met through the use of a double walled diesel tank. If the tank is ruptured in any way,
the second level of containment will prevent a spill of the diesel. The spec sheet on MS-15 (sheet 9 of
the PDF) of the plans labels the tank as "210 gallon double -walled UL listed Washington State
compliant sub -base fuel tank, 125% containment with stub -up area".
BMP2
o There are no catch basins in the immediate vicinity of the generator.
BMP3
o All maintenance will be performed within the housing of the generator. The top of the tank has a lip that
will contain small drips and spills.
o A spill cleanup kit will be kept in the equipment compound adjacent to the generator compound. All
Verizon Wireless service techs will be familiar with the use of this equipment.
o The generator diesel tank will be equipped with spill/leak alarms. Any leaking of the tank will trigger the
alarm and alert Verizon Wireless service techs remotely. Causes for the leak will then be dealt with
immediately.
o The generator will be continually monitored remotely and inspected routinely.
I
MIR
Additional BMP's
o The generator will be installed with a 5 gallon spill/fill box. This box will prevent the accidental spilling of
diesel fuel while filling the 210 gallon tank.
If you have additional questions or would like me to address additional sections of the KC SPPM please let me know and
I'd be happy to take a look. Please feel free to reply to this email or give me a call at my number below and we can
discuss this site further.
Thank you

RE: Request for Process I, "Director's Approval", Verizon Wireless, SEA SW 320th,
2105 SW 320th Street, Proposed Emergency Back-up Generator at Existing Wireless
Facility Site, Parcel No.1221039030
Dear Planning Division:
On behalf of Verizon Wireless, Lynx Consulting is requesting a Type I administrative land use review
and decision for a proposed 30kW diesel generator addition to an existing wireless facility located at
2105 SW 320th Street, to be located within a proposed 4'8" x 10'2" fenced area.
The property is zoned PO. There is an existing wireless facility at this location which presently
consists of equipment surrounded by fencing. This proposal would create a new fenced area by the
aforementioned 4'8" x 107' and the generator would be placed within the fenced area. The fence is
proposed to be 8' in height and built with sound attenuation materials (wood with sound barrier and
sound absorbing materials installed between the vertical posts). The proposed fence height of
8' exceeds the standard -allowable height of 6' and we will be applying for a separate, structural permit
for the fence.
The generator area meets the required setbacks of 20' from all property lines. The site will be also be
surrounded by a five-foot landscape buffer, consisting of arborvitae (3 gallon size, 4 to 5 feet in
height), planted at 3' OC minimum, or as otherwise recommended by the City.
The proposed generator is for back-up emergency power outages and therefore provides public
benefit. The generator will run during power outages and during routine, once a week testing. We
have included a Noise Study for the proposal, which states with proper sound attenuation with noise
barriers, sound absorptive material and raising the fence level to 8' will achieve the 15-minute noise
limit of 62 dBA during daytime maintenance cycling at the nearest receiving property.

Re: Acoustical Report — Verizon SEA SW 320th Street
Site: 2105 SW 320th Street, Federal Way, WA 98003
Dear Bert,
This report presents a noise survey performed in the immediate vicinity of the proposed
Verizon telecommunications facility at 2105 SW 320th Street in Federal Way, Washington. This
noise survey extends from the proposed equipment to the nearest properties. The purpose of
this report is to document the existing conditions and the impacts of the acoustical changes
due to the proposed equipment.
Ambient Conditions
Existing ambient sound levels of the site were measured on August 1, 2014 with a Larson -
Davis 824 sound level meter. Measurements were conducted as close to the proposed
location as possible. The average ambient noise level was 66 dBA primarily due to traffic from
SW 320th Street. The weather during the measurements was overcast with dry roads.
Code Requirements
The site is located within the City of Federal Way Zoning jurisdiction on property designated
with a PO (Professional Office) zoning. The nearest receiving property, to the north, is zoned
RM3600 (Multifamily Residential).
The proposed new equipment consists of an emergency generator. The generator will run
once a week during daytime hours for maintenance and testing purposes only.
Federal Way Municipal Code Section 7.10.050 adopts by reference the maximum noise levels
set forth in WAC 173-60. Under WAC 173-60-040, noise from equipment on a Class B EDNA
(Commercial) property is limited as follows:
Class A EDNA (Residential) Receiver: Noise is limited to 57 dBA during daytime hours.
Additionally, WAC 173-60-040 allows that during any one -hour period, the maximum
permissible noise level may be exceeded by 5 dBA for a 15 minute period. Therefore, the
generator must not exceed 62 dBA when running during daytime hours for maintenance
testing. The generator is exempt during emergency operation.
