Project Narrative
Project Name: 600 SW 10th Street – Parking Lot Improvements
Parcel: 214600-0050
Project Size: 4.38 acres
Zoning: IM – Medium Industrial
The existing parcel includes a large warehouse with internal office space and a vehicular and
truck parking lot. This facility has been historically used for storing and shipping products as a
metal supplier for approximately 14 years. The project scope anticipated by this pre-app
submittal seeks to convert an un-improved laydown area and an asphalt drive aisle behind the
building to an asphalt parking lot, striping, and landscaping for parking of Tesla vehicles for the
proposed collision center. The project team has evaluated the parking lot to accommodate a
maximum number of stalls while maintaining clearances from existing elements and minimizing
site impacts to the back half of the lot.
The proposed Tesla Center will be built-out in a former Ryerson Manufacturing plant. The
property will be used for Tesla electric vehicle sales, service, delivery, and collision repair.
Service will operate 64 work bays with 5,987 sq. ft of parts storage. This service area will be
gated, with the intended use for private vehicle storage for Tesla services only and not publicly
accessible. 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.
There are no steep slopes, wetlands, or significant tree stands within the project boundary.
The US Geological Survey classifies the soil beneath the parcel as Ur - Urban land. A detailed
geotechnical analysis and soil classification will be provided later. The topography of the project
area generally slopes from northeast to southwest with approximately 2.5 feet of fall across the
site.
There are no off-site improvements being proposed by this project. Demolishing activities
include removal of asphalt and minor clearing and grubbing. Onsite improvements include
asphalt pavement, concrete curbing, landscaping, stormwater management BMPs, drainage
structures, and striping. The project site is accessed from the existing driveway along the west
side of the building. The existing north access to Seneca Avenue will remain gated and
unchanged. The property is currently zoned as Medium Industrial (IM) and the setbacks are
indicated on the preliminary site plan. The proposed use is to provide temporary parking for e-
commerce vehicles. No bulk storage or storing of hazardous materials is being proposed.

To facilitate 550 parking stalls, the project proposes 406 new 90-degree parking spaces
dedicated to the Tesla collision center for private parking. A total of 11 ADA stalls and 4
compact stalls are provided.
A 10-foot landscape setback is included along the northern and western edges of the parking
lot to meet or exceed the landscaping buffer requirement. Drive aisles are designed for fire lane
accessibility and vehicular turning movements. Concrete curbing is proposed around
landscaped areas. Steel bollards are to be installed as required to protect the north side of the
building and all safety requirements regarding loading zones at bay doors. Striping and signage
will be included to delineate emergency vehicle access and to provide no-parking at the loading
zones.
This project is required to match the existing peak flow control standard. Stormwater
Management Best Management Practices (BMPs) with emphasis on Low Impact Development
principles and practices are to address water quality and runoff requirements. Possible BMPs
may include bioretention cells, planters, or swales to meet Core Requirements #8 and #9.
Underground vaults or tanks may be used to attenuate any excess of the 2 -year, 10-year, and
100-year flow rates.
The perimeter parking lot landscaping strip meets RMC 4-4-070 (H)(4) which requires a
minimum width of 10 feet. The interior parking lot landscaping strip meets RMC 4 -4-070 (H)(5)
which requires a minimum width of 8 feet. These landscaped strips may be simultaneously used
as BMPs.
This project is expected to remove 98,000 square feet of existing asphalt and install 204,000
square feet of new asphalt pavement. Standard pavement base and top courses are expected
to be used. Preliminary landscape area is approximately 30,700 square feet. Concrete traffic
curb will protect the landscape areas. Based on the existing slope of the project site, no import
or export of earthwork is expected.
There are no significant trees identified to be removed by this project. The existing trees along
the western and northern property lines are expected to remain.
The estimated cost of construction at this stage of the process is $10,088,015.
