SUBJECT: Pape’ Kenworth Northwest – Federal Way, WA
Updated Parking Assessment
TENW Project No. 6011
This memorandum documents the parking assessment for the proposed Federal Way PapeÊ Kenworth
Northwest facility. This is an update to our previous parking assessment memo dated March 5, 2020 to
addresses comments included City of Federal Way Technical Review Comments dated April 24, 2020 and
the current proposed site plan.
This parking assessment was completed to identify the parking stalls needed at the proposed PapeÊ site in
Federal Way based on the parking provided at other similar PapeÊ Kenworth facilities currently in operation.
The proposed site is located on the north side of S 320th Street east of I-5 and west of 32nd Ave S, on 7
parcels currently in unincorporated King County that will be annexed into the City of Federal Way.

SF outdoor truck storage area located on the southeast corner of the site. The proposed uses include PapeÊ
Kenworth Northwest new truck sales, maintenance facility, offices, and a body repair shop. Access to the

Parking Assessment
City of Federal Way Required Parking
The City of Federal Way parking code requirements for the project are based on the zone chart of FWRC
19.220.030. Table 2 summarizes the code requirements for the proposed project.

Truck sales, service,

Total Code Required Parking Stalls = 316
As shown in Table 2, the CityÊs code-required parking for the project is 316 spaces. It should be noted that
Per FWRC 19.125.170(5), the outdoor truck storage area was included in calculating the gross floor area
(GFA) of the project, and included in the required code parking calculation.
PapeÊ Kenworth Parking Demand
The latest version of ITEÊs Parking Generation, does not include a comparable land use to the proposed PapeÊ
Kenworth use. As a result, the parking needed for the proposed project was based on parking provided at
four existing PapeÊ Kenworth facilities located in Washington, Oregon, and California.
Site Address Building Area (SF)
1. Bakersfield, CA 19414 Quinn Road 24,000
2. Portland, OR 550 NE Columbia Blvd 75,000
3. SeaTac, WA 20220 International Blvd. S. 33,125
4. Lakewood, WA 12507 Pacific Hwy SW 27,000
The parking provided for staff and customers at the four PapeÊ sites was confirmed by on-site operators at each
location, and compared to the total building area at each site. Based on this data, an average parking supply
ratio of parking stalls per 1,000 square feet of building area was derived. Outdoor truck storage areas were
not included in the building square footages. A summary of the parking data is provided next in Table 2.

3. SeaTac, WA 33,125 SF 35 1.06
4. Lakewood, WA 27,000 SF 70 2.59
TOTAL = 159,125 SF 219 1.38
As shown in Table 2, based on the parking provided at the four existing PapeÊ Kenworth facilities, an average
parking ratio of 1.38 parking stalls/1,000 SF building was derived. Based on this, the proposed 79,774
SF PapeÊ Kenworth Federal Way site would need 111 parking spaces (79,774 X 1.38/1,000). Parking
stall calculations were rounded upwards in accordance with FWRC 19.130.040.
