Date:March 7, 2024
Subject: Tesla Sales and Service Center Renton (KH #194612001) – Phase I
Kimley-Horn and Associates, Inc. (Kimley-Horn) has been retained to provide a Phase I memorandum
for the proposed Tesla Sales and Service Center Renton (Development). This memorandum
summarizes the trip generation, trip distribution, proposed study intersections, and mitigation fees for
the Development. The Development is located at 600 SW 10 th Street in the City of Renton (City) on the
north side of SW 10th Street, west of Lind Avenue. Per King County Parcel Viewer, the parcel is listed
as occupied with an existing 114,531 square foot (SF) building of which 7.9% (9,048 SF) is allocated
as office space with the remaining 105,483 SF as manufacturing. A site vicinity map is shown in Figure
1.

1. TRIP GENERATION
The Development is proposed to repurpose the existing warehouse to an automobile sales and collision
service and repair center. The trip generation calculations have been performed using data published
by the Institute of Transportation Engineers (ITE)Trip Generation Manual, 11th Edition (2021). The
average trip generation rates for ITE Land Use Codes (LUC) 840, Automobile Sales (New), LUC 140,
Manufacturing, and LUC 710, General Office, have been used for the trip generation calculations. The
existing building is to be repurposed with construction of the Development. Therefore, the existing trips
should be credited to the Development as it has not been vacant for more than 3-years. The trip
generation for the Development are summarized in Table 1.

The Development is anticipated to generate approximately 633 new ADTs with approximately 14 new
AM peak-hour trips and approximately 21 new PM peak-hour trips. The trip generation calculations
have been provided in Appendix A.
2. TRIP DISTRIBUTION
Trip distribution and assignments for the proposed Development are based on prior projects in the site
vicinity and the location of other Tesla service centers. The Development trip distribution is:
l 30% to and from the south along Rainier Avenue S (SR-167)
l 20% to and from the west along I-405
l 20% to and from the east along I-405
l 15% to and from the north along Rainier Avenue S (SR-167)
l 10% to and from the east along SW Grady Way
l 5% to and from the west along SW Grady Way
Detailed trip distributions for the AM and PM peak-hours are shown in Figure 2 and Figure 3,
respectively.

3. STUDY INTERSECTIONS
In addition to looking at the site accesses; the proposed study intersections have been identified based
on anticipated impacts in the site vicinity. The following intersections have been identified as proposed
study intersections if required by the City of Renton:
l Lind Avenue SW at SW 10th Street
l Lind Avenue SW at Grady Way
l Rainier Avenue S (SR-167) at SW Grady Way
The Development will utilize the three existing accesses directly to SW 10 th Street along the south side
of the Development with no changes proposed. The Development will have 550 parking spaces on-
site, 451 for service and repair, 84 for general office, 10 ADA spaces, 1 ADA van space, and 4 for
compact vehicles.
4. TRANSPORTATION IMPACT FEES
The transportation impact fees have been calculated using the City of Renton Fee Schedule 2023-2024
worksheet. The current fee for the credit using ITE LUC 140, Manufacturing, is $10.36 per SF and for
LUC 710, General Office, is $14.07 per SF. There is no fee available for ITE LUC 840, Automobile
Sales (New), therefore the current fee of $8,031.94 per PM peak-hour person vehicle trip was used for
the proposed land use. It is anticipated that each vehicle trip will be a person vehicle trip. This fee is
subject to change based on calculations by the City Traffic Engineer and is not calculated until building
permit issuance.
After verification with City of Renton on March 6, 2024, it is understood that based on available records
the existing development use is mostly steel manufacturing use and small portion is office/distribution.
Kimley-Horn performed a record drawing search and it was determined that 9,048 SF of the existing
building was designated as general office use and 105,483 SF was designated as steel manufacturing.
With that info in hand, the Development will receive a $1,220,109.24 credit for the existing
manufacturing and general office on-site. A traffic mitigation fee of $899,577.28 was calculated for the
112 PM peak-hours trips generated by the proposed development. Therefore, the Development will
have an excess credit in traffic mitigation fees of $320,531.96 after credit for the existing uses has
been deducted. The total transportation impact fees are summarized in Table 2. The City of Renton
Fee Schedule 2023-2024 worksheet is provided in Appendix B.

Operational Letter - Tesla Center in Renton, WA
Tesla is proposing a Tesla Center at 600 SW 10th St Renton, WA. We plan on using this property for
Tesla electric vehicle sales, service, delivery, and collision repair.
The Tesla Center will be built-out in a former Ryerson Manufacturing plant. Ryerson is an online metals
supplier, processor, and distributer of many varieties of metals production. Tesla produces electric
vehicles that solely use electricity and no gasoline; it is not a hybrid vehicle. Our vehicles don’t have
internal combustion engines (ICE); thus, the vehicle doesn’t have a fuel tank, use oil, an exhaust system,
transmission, or many of the other components that require the storage and use of hazardous materials
on site or traditional vehicle ventilation. Our vehicles are extremely environmentally sensitive.
Our showroom will have energy products and two vehicles on display for customers to experience our
vehicles. Customers will also be able to perform a demonstration drive with the vehicles, there will be 4 -6
demo vehicles on- site. Sold vehicles will be stored and taken possession of upon delivery. We are
forecasting 22 deliveries per day. There will be no available inventory for sale stored at the property.
The service work that will be done here will be standard servicing of our electric vehicles, which will
include software updates, tire replacement, tire balancing, alignment, minor body work (only replacing
doors or the rear hatch), topping off water, and an occasional battery replacement.
Most service repairs are handled in under an hour or two. In this case, typically customers make use of
the customer lounge while their vehicle is repaired. In the case where vehicle repairs will take several
hours, customers have the option of waiting at the center or taking a vehicle from our loaner fleet while
they await the repair. Service will operate 64 work bays with 5,987sq. ft of parts storage. The expected
demand for the service center is forecasting 158 repairs per day. Hazardous chemicals stored in this
facility are extremely minimal quantities, consisting primarily of cleaning materials, no oil, gasoline, or
other hazardous substances traditionally part of internal combustion vehicle repairs will be found at this
service center. Moving Tesla vehicles within an interior space is extremely environmentally safe, as the
vehicles have no exhaust.
Expected hours of operation for this Tesla Service Center are Monday through Saturday from 8:00AM to
5:00PM and on Sundays from 11:00AM to 5:00PM. There will be two shifts. First shift from 6am-3pm and
a second at 3pm-11pm. Total employee count is expected to be abo ut 60 employees, 40 of which would
be certified technicians (mechanics)/service support staff, 19-25 employees will be working a shift at any
given time.
Collision repair will perform assessments for damaged Tesla vehicles and if needed, the repair or
replacement of the following: frame, body panels, and any mechanical and trim components.
Customers who come to the collision facility will primarily be by appointment only. We estimate 5 to 20
appointment customers per day. Day of customers (walk-ins) are limited, but we estimate 1 per day.
Customers will either bring their car in or have a provider tow their car to our facility on the day of their
appointment. After dropping off their cars, customers are eligible for a ride share voucher (ie. Uber) to get
to their next destination. When their car is complete, customers are usually dropped off by a 3rd party or
walk-in after returning a rental.
The anticipated customer facing Collision hours of shop operation will be Monday through Friday from 8am
to 7pm, with anticipated future operations being 24/7. During the initial operating hours, approximately 50
employees will provide Collision repair services for approximately 60 -80 cars each week. Each shift will
have the same number of employees. All cars will be repaired within the 4 walls of the facility and public
view will be limited. Work in progress (WIP) cars will be inside the building. Repairs typically take 11-16
days on average.
A - 5
The existing parking lot will be partially fenced off for public and private uses. The private use area will be
screened from public view.
At Tesla, we strive to achieve an uncompromising approach to our vehicles. Our intention is to provide
manufacturer support to every vehicle we build from centrally centers throughout the country. Without a
doubt, the Renton area is part of our customer heartland, and we hope to be welcomed as part of the
City’s high standards of quality and lifestyle.
Should you have any questions, or require additional information, please do not hesitate to contact us.
Thank you,
