Land Use Issues — Stormwater
Surface water runoff control and water quality treatment will be required per the 2016 King County
Surface Water Design Manual (KCSWDM) and the City of Federal Way Addendum to the King
County Surface Water Design Manual (Addendum). This project meets the requirements for a Full
Drainage Review. At the time of land use site plan submittal, a preliminary Technical Information
Report (TIR), addressing the relevance of the project to the nine core and five special requirements of
the KCSWDM will be required. A Level 1 downstream analysis shall also be provided in the
preliminary TIR. The City has 1" = 100', five-foot contour planimetric maps in GIS format that may
be used for basin analysis.
2. The project lies within a Conservation flow control area, thus the applicant must design the flow
control facility to meet this performance criteria. In addition to flow control facilities, Best
Management Practices (BMP's) are required as outlined in the KCSWDM. The project also lies
within an Enhanced Basic Water Quality Area. Water Quality Treatment shall be designed to meet
the treatment criteria of the Enhanced Basic Water Quality Menu.
3. In addition to the KCSWDM, our initial review suggests that FWRC Section 19.30.120,
"Nonconforming Water Quality Improvements" applies to this site. Specifically, the following item(s)
is(are) applicable: (pick those that apply)
1.a. Redevelopment which involves the creation or addition of impervious surfaces having an area of
5,000 square feet or more;
1.b. Redevelopment which involves the construction or replacement of a building footprint or other
structure having a surface area of 5,000 square feet or more, or which involves the expansion of a
building footprint or other structure by 5,000 square feet of surface area or more;
1.e. Redevelopment which involves the repair or replacement of 5,000 square feet or more of an
impervious surface, when such redevelopment is not part of a routine maintenance activity;
Therefore, water quality treatment will be required for the entire site, including new and existing
pollution generating impervious surfaces. "Site", as defined in section 1.1.13 footnote 2 of the
Addendum, refers to all parcels under contiguous ownership, so treatment will need to be upgraded
for the entire Costco site as well as the gas station. Treatment options must be selected from the
Enhanced Basic Water Quality Menu provided in the KCSWDM.
4. If infiltration is proposed, soil logs prepared by a licensed geotechnical engineer or septic designer
must be provided to verify infiltration suitability.
5. Detention and water quality must be above ground (i.e. open pond). Underground facilities are
allowed only with approval from the City of Federal Way Public Works Department. Drainage for the
pump islands must be routed to sanitary sewer.
6. Show the proposed location and dimensions of the detention and water quality facilities on the
preliminary plans.

7. If more than one acre will be disturbed during construction, a National Pollutant Discharge
Elimination System (NPDES) construction storm water permit may be required. Information
regarding this permit can be obtained from the Washington State Department of Ecology at
http://www.ecy.wa.goy/programs/wq/stormwater/construction/index.html or by calling 360-407-
6048.
Right -of -Way Improvements
1. See the Traffic Division comments from Sarady Long, Sr. Transportation Planning Engineer, for
traffic related items.
2. If dedication of additional right-of-way is required to install street frontage improvements, the
dedication shall be conveyed to the City through a statutory warranty deed. The dedicated area must
have clear title prior to recording.
3. All stormwater treatment and detention requirements outlined above may apply to any improvements
within the public right-of-way.
Building (or EN) Permit Issues
1. Engineered plans are required for clearing, grading, road construction, and utility work. Plans must be
reviewed and approved by the City. Engineering review fees are $2,503.00' for the first 12 hours of
review, and $139.00 per hour for additional review time. A final TIR shall be prepared for the project
and submitted with the engineering plans. Both the TIR and the plans will require the signature/seal
of a professional engineer registered/licensed in the state of Washington.
2. The Federal Way Public Works Development Standards Manual (including standard detail drawings,
standard notes, and engineering checklists) is available on the City's website at
http://www.cilyoffederalway.com/index.aspx?nid=171 to assist the applicant's engineer in preparing
the plans and TIR.
Bonding is required for all street improvements and temporary erosion and sediment control measures
associated with the project. The bond amount shall be 120 percent of the estimated costs of the
improvements. An administrative fee deposit will need to accompany the bond to cover any possible
legal fees in the event the bond must be called. Upon completion of the installation of the
improvements, and final approval of the Public Works Inspector, the bond will be reduced to 30
percent of the original amount and held for a two-year maintenance period.
4. The developer will be responsible for the maintenance of all storm drainage facilities (including the
detention and water quality facilities) and street systems during the two-year maintenance period.,
During that time, the Public Works Inspector will make periodic visits to the site to ensure the
developer's compliance with the maintenance requirements. Upon satisfactory completion of the two-
year maintenance period, the remainder of the bond will be released. Maintenance for public roads
and subdivision drainage facilities then become the responsibility of the City. Maintenance for private
roads and drainage facilities, including short plats, remain the responsibility of the individual property
owners.

Transportation Concurrency Analysis (FWRC 19.90)
1. Based on the submitted materials to expand the fueling canopy by approximately 3,300 square feet to
accommodate 8 new vehicle fueling positions, the Institute of Transportation Engineers (ITE) Trip
Generation - 1 Ot" Edition, land use code 944 (Gasoline/Service Station), the proposed project is
expected to generate 38 new PM peak hour trips (50% internal captured and 32% Pass -By).
2. A concurrency permit is required for this development project. The PW Traffic Division will perform
concurrency analysis to determine if adequate roadway capacity exists during the weekday PM peak
period to accommodate the proposed development. Please note that supplemental transportation
analysis and concurrency mitigation may be required if the proposed project creates an impact not
anticipated in the six -year Transportation Improvement Plan (TIP).
The estimated fee for the concurrency permit application is $4,790 (11 - 50 Trips). This fee is an
estimate and based on the materials submitted for the preapplication meeting. The concurrency
application fee must be paid in full at the time the concurrency permit application is submitted with
land use application. The fee may change based on any changes in the estimated weekday PM peak
hour trips as identified in the concurrency application. The applicant has the option of having an
independent traffic engineer prepare the concurrency analysis consistent with City procedures;
however, the fee remains the same.
Transportation Impact Analysis (TIA) (FWRC 19.135)
1. A Traffic Impact Analysis (TIA) prepared by engineer licensed in the state of Washington is required
for this development project. The engineer should contact the Traffic Division for a scoping sheet in
the initial stages of their study. The TIA should include the following analysis:
■ A specialized land use trip generation study
• Queuing analysis access points for morning, evening, and Saturday peak hours

Transportation Impact Fees (TIF) (FWRC 19.91)
Based on the submitted materials for 8 new vehicle fueling positions, the estimated traffic impact fee is
S85.193. Please note, the actual impact fee will be calculated at the time a completed building permit
application is filed and must be paid prior to permit issuance.
Street Frontage Improvements (FWRC 19.135)
l . Based on King County Assessor's record and the submitted materials, it appears this proposal meets
the 25 percent threshold criteria for requiring street frontage improvements as identified in the FWRC
19.135.030. The applicant/owner may submit an appraisal for the subject property. The Public Works
Development Services Division will evaluate the submitted appraisal data to determine if the project
actually meets the City's 25 percent threshold for requiring street frontage improvements.
2. The applicant/owner would be expected to construct street improvements consistent with the planned
roadway cross -sections as shown in Map I1I-4 in Chapter III of the Federal Way Comprehensive Plan
(FWCP) and Capital Improvement Program (CIP) shown as Table III-10 (FWRC 19.135.040). Based
on the materials submitted, staff conducted a limited analysis to determine the required street
improvements. The applicant would be expected to construct improvements on the following streets
to the City's planned roadway cross -sections:
S 352"d St. a Principal Collector planned as a Type "M" street, consisting of 36-foot street with
curb and gutter, 6-foot planter strips with street trees, 8-foot sidewalks, and street lights in a 70-
foot right-of-way (ROW). Assuming a symmetrical cross section, 5-foot right-of-way dedication
and half street improvements are required as measured from the street centerline. S 352"d St. is
improved with vertical curb gutter, sidewalks, streetlights, etc., on both sides of the street.
However, the improvements on the north side of the street are not to current standard and will not
likely meet ADA requirements.
Enchanted Parkway S (SR 161) is a Principal Arterial planned as a Type "C" street, consisting of
a 72-foot street with curb and gutter, 6-foot planter strips with street trees, 8-foot sidewalks, and
street lights in a 106-foot right-of-way (ROW). Assuming a symmetrical cross section, half street
improvements are required as measured from the street centerline. The frontage on Enchanted
Parkway S is improved with 5 lanes, bike lane, vertical curb gutter, sidewalks, streetlights, etc.
However, the sidewalk, driveway, and ramps may not meet current ADA standards. Furthermore,
it appears that part of the sidewalk next to the fueling may not be located within the ROW. The
applicant may submit a justification report outlining to the Public Works Director on how the
existing facilities meet ADA standards.
■ The applicant may make a written request to the Public Works Director to modify, defer, or waive
the required street improvements (FWRC 19.135.070). These modification requests currently
have a nominal review fee currently at $278.00.
Access Management (FWRC 19.135)
1. Access management standards are based on roadway safety and capacity requirements. FWRC
19.135.280 provides access standards for streets based on planned roadway cross -sections.
Furthermore, access on state highways shall be limited to a maximum spacing of 250 feet with only
18-104024-00-PC Doc ID: 78302
Mr. Moseley
October 26, 2018
Page 8
one access per parcel. Access may be further restricted if such access would interfere with -the 95"'
percentile queue lengths from any existing traffic control device.
2. The westerly driveway on S 352 St. should be redesigned to minimize queuing and to facilitate on -
site traffic circulation. This may include increasing throat length to a minimum of 50' and modifying
the existing standard curb cut to radius. Also, a left turn lane from the internal drive aisle into the
fueling site should be explored.
3. The internal driveway off of Enchanted Parkway S between Costco fueling facility and Olive Garden
restaurant should be redesigned to incorporate a mini -roundabout or other alternatives.
4. Minimum throat length for non -single-family driveways shall be 40 feet minimum, 50 feet desirable.
Throat length is measured from the face of curb (or edge of traveled way if no curb exists) on the
public street to the first conflicting drive aisle or parking movements that would conflict with entering
and exiting traffic.

COSTCO TRIP GENERATION DATA
Surveys conducted at established Costco sites have shown that Costco Warehouses typically generate
higher traffic volumes than other land uses with similar building sizes. An overview of weekday p.m.
peak hour trip generation characteristics is provided that has been collected between 2001 and 2011
at Costco Wholesale locations containing fuel stations. The rates shown for the sites include the fuel
station as part of the calculated trip rate. In addition to the driveway trip rates, customer survey
information has been included to provide the percentage of primary, pass -by, and diverted trips, as
further described below.
■ Primary Trips (an entirely new trip on the roadway system for the express purpose of driving
to and from Costco);
■ Pass -by Trips (existing trips that are on roadways adjacent to the site which allow the motorist
to turn into the Costco development, and then continue on to their ultimate destination when
their shopping is concluded); and
• Diverted -Linked Trips (existing trips on nearby roadways in which the motorist makes a
decision to drive out -of -direction for a distance to stop at Costco, and when their shopping is
concluded, continue on their trip to the ultimate destination).
Trip Characteristics Application
The analysis models prepared for the Dallas site should explicitly account for pass -by and diverted trip
impacts at the study intersections. Typically, pass -by trips would have an impact only at the site -
access driveways, whereas the impact of diverted trips could extend throughout the study area
intersections (these would be modeled similar to net new trips at many or all of the study area
intersections in the operations models). The key difference between inclusion and omission of the
diverted trips is related to the overall vehicle miles traveled (VMT), as diverted trips do not create the
same system impacts (air quality, noise, and freeway impacts) that entirely new trips to the system
could create.
The previously surveyed Costco buildings are sited in a variety of locations, some adjacent to
freeways/arterials, others a couple blocks away. This variation in store locations results in differences
in diverted and pass -by trips from store to store. For example, sites adjacent to major arterial
roadways tend to exhibit a high percentage of pass -by trips and.a lower percentage of diverted trips.
Similarly, Costco facilities located a.block,or two ayray from a'freeway tend to experience a higher
percentage of diverted trips. Given these factors, diverted and pass -by trips should be considered
together, •with';engineering judgment used to identify how these two teip characteristics should be
applied. '
Trip Generation Estimate
Trip generation studies were conducted at Costco Wholesale sites located across the country using
industry standard engineering practices consistent with guidance within the Institute of
Transportation Engineers (ITE) standard reference, Trip Generation Handbook, 2nd Edition. These
surveys were conducted between 2001 and 2011, and include surveys of twenty-seven Costco
Warehouses with fuel centers3. The Costco Wholesale buildings surveyed range in size between
122,528 square -feet and 162,115 square -feet, with an average size of 143,869 square -feet. The fuel
centers in the sample range between 12 and 20 fueling positions. The trip generation rates are
correlated to the overall warehouse size regardless of the number of fueling positions as trip
generation studies are conducted at the site entrances. Table Al summarizes the average trip rates
recorded; additional details on these sites are included at the end of this appendix.

COSTCO FUEL CENTER CHARACTERISTICS The Costco Wholesale trip generation rates shown in Table Al inherently accounts for fuel station
trips within the overall rate. However, supplemental information on the fuel centers from
isolated studies is provided to describe the fuel center characteristics separately. This information
was collected to highlight the trip characteristics of adding fuel centers to existing Costco Wholesale
sites, but the isolated fuel center data can also be considered applicable to the Elk Grove site
during the weekday a.m. peak hour, when the Costco warehouse is closed.
Information related to internal trip capture and pass -by trip percentages was collected by
interviewing Costco Gasoline customers about their trip patterns as they are purchasing fuel. Because
Costco member cards are also scanned as part of fuel center and Costco purchases, transaction data
was also matched up to identify internalization rates.
3 Daily trip data was collected at eight of the sites, weekday a.m. peak hour data was collected at two sites, and
weekday p.m. peak hour data was collected at 27 sites.

COSTCO FUEL STATION TRIP CHARACTERISTICS
The data collected at existing Costco Gasoline sites indicate the following general trip generation
characteristics:
Costco Gasoline fuel stations are an ancillary use for the warehouse and there is a large
proportion of shared trips between the two.
The fuel stations are member -only and require a membership card for pump activation.
Credit/debit card is the only method of payment at the fuel stations and they do not provide
any other services (automotive or convenience) besides gas.
• The fuel stations are staffed by a minimum of one attendant who is trained to help members
operate the pumps and direct waiting vehicles to open pumps to manage on -site queuing and
circulation.
The unique nature of Costco operations and its membership requirements result in different trip
characteristics than those observed at the standard fuel stations summarized in ITE Trip Generation.
The percentage of pass -by trips at Costco fuel stations is considerably lower than that reported in ITE
Trip Generation for typical fuel stations. Correspondingly, membership requirements also have a
significant effect on trip internalization (or sharing of trips) between the warehouse and the fuel
station. Fewer people exclusively visit a Costco fuel station during the evening commute period (in
comparison to a typical stand-alone station) because they have another primary purpose for visiting
the site (that being a trip to the warehouse).
Internal Fuel Station Trips
A key finding from the driver surveys conducted at Costco facilities is the fact that approximately 50
percent of the weekday p.m. peak hour trips to and from Costco fueling stations are internal capture
trips. Internal capture trips account for those customers who patronize both the warehouse and the
gasoline pumps during a single visit to the Costco site. As such, although they account for a trip to
both the warehouse and the fuel station, they only result in one overall vehicle trip to the site and on
the surrounding transportation system. On average, 50 percent of the customers buying gas during
the weekday p.m. peak hour are customers whose main purpose to the site is to visit the Costco
warehouse. At some sites this number ranges as high as 75 percent but for the purposes of analysis a
conservative average estimate is typically used.

Trip Generation Assumptions and Methods
Future Fuel Station Expansion Generation Characteristics
The market area of the Elk Grove Costco is already defined through existing membership and
operations. As such, it's unlikely that trip generation of the fuel station expansion will increase
directly in proportion to the increased number of fueling positions. Before and after studies have
shown that the additional fueling positions will serve to more efficiently and effectively process the
current peak demand at the fuel station, thus reducing wait times, vehicle queuing, and vehicle idling.
Although the standard reference manual ITE Trip Generation currently reports trip generation for
gasoline stations based on the independent variable of fueling positions, more recent transportation
studies indicate that other variables besides the specific number of fueling pumps have a much larger
influence on trip generation. As such, the profession is moving towards modifying this for the gasoline
station land use codes and working on studies that include different independent variables.
To confirm this approach, before and after data from other comparable Costco Gasoline fuel station
expansion sites was reviewed to determine a more representative relationship between new trip
generation and the addition of fueling positions to the existing station.
KAI worked with Costco to identify eight other Costco Gasoline locations that have expanded in size.
There are several examples where Costco Gasoline fuel stations had been expanded from three
islands (12 fueling positions) to four islands (16 fueling positions), one example of expanding from 16
to 20 positions, and one example of expanding from 12 to 20 positions. The comparable expansion
sites identified were:
• Kona, Hawaii
■ Orem, Utah
• Vancouver, Washington
• Concord, California
• Folsom, California
■ Waipio, Hawaii
• Issaquah, Washington
• Salem, Oregon
In order to work with a representative sample size, Costco provided fuel transactions collected on an
hourly basis for a period before and after the expansion at each of these locations. Only data that was
collected during similar months of the year prior to and after the expansion was included in this
summary (for example, fuel transactions for the months of March and April before the expansion
were compared to fuel transactions for the months of March and April after the expansion). The
results of this before and after comparison for the seven listed sites are provided in Table D1.

' Expansion from 16 fueling positions to 20 fueling positions
z Expansion from 12 fueling positions to 20 fueling positions
All other examples are expansions from 12 to 16 fueling positions
As shown in Table D1, each of the sites recorded an increase in the number of Average Weekday Daily
Fuel Transactions. However, the increase found in all situations is significantly less than what would
be calculated from a direct linear relationship to the number of vehicle fueling positions. Using a
linear relationship, expanding the fuel station from 12 to 16 fueling positions would equate to an
increase in activity or trip generation of 33%, expanding from 16 to 20 positions would equate to an
increase of 25%, and expanding from 12 to 20 would equate to an increase of 67%. However, the
actual before and after data only shows an average increase of 9.2% in daily fuel transactions.
This data demonstrates that increasing the number of fueling positions at the Elk Grove Costco
Gasoline facility will not result in a direct linear increase in trip generation. The before and after data
captures the change in demand that results from reducing peak hour queues and wait times at the
fuel stations due to the effect of latent demand and more efficient peak operations. In all cases, peak
queues and wait times are significantly reduced and those members who previously chose not to
purchase fuel because of the wait times will likely do so in either case once the operations are
improved.

Project Overview
Costco Fueling Facility Expansion
35100 Enchanted Parkway S.
Federal Way, WA 98003
The project includes the expansion of the existing fuel canopy over four (4) new multi -product dispensers
(MPDs), replacement of the existing controller enclosure with a new controller enclosure in the northwest
corner of the facility and associated site improvements. The facility will be expanded on the north side; the
construction area will be contained to the fuel facility area in the southwest corner of the Costco site in
Federal Way, Washington.
The property is zoned Commercial Enterprise (CE). Surrounding properties are zoned Commercial
Enterprise (CE) and surrounding uses primarily consist of commercial retail. The fuel facility was originally
approved under Use Permit# 00-102669-00-UP and SEPA# 00-102670-00-SE, a subsequent remodel in
2010, under permit# 10-103846-00-FP, added an underground fuel additive storage tank and the last
remodel in 2012, under permit# 12-100598-00-FP, modified the fuel additive UST from manual operation
to automated operation.
The intent of the expansion is to facilitate on -site circulation to improve the existing membership experience
at the facility. Based on data from other expanded Costco gas stations, the additional MPDs are not
expected to generate a significant number of new trips to the fueling facility; the increased fueling positions
will reduce wait times thereby improving transaction efficiency and purchasing experience for the members
already utilizing the facility. Project construction will be completed in a single phase and commence after
approval of the applicable permits. The existing fueling facility will remain open during construction of the
expansion
