AGENDA MEMORANDUM
Item No. 8j
ACTION ITEM Date of Meeting August 12, 2025
DATE : August 4, 2025
TO: Stephen P. Metruck, Executive Director
FROM: Mark Leutwiler, Interim Director of Airport Operations
Eileen Francisco, Director of Aviation Project Management Group
SUBJECT: S. 160th St TNC Lot Improvements (CIP# 801186)
Amount of this request: $1,100,000
Total estimated project cost:
$8,400,000
ACTION REQUESTED
Request Commission authorization for the Executive Director to take all steps necessary to
complete the South 160th Street TNC Lot Improvement Project at Seattle-Tacoma International
Airport (SEA). This request is an increase in the amount of $1,100,000 for a total authorization
of $8,400,000.
EXECUTIVE SUMMARY
The Port-owned South 160th Street Ground Transportation (GT) holding lot is used by taxis and
Transportation Network Companies (TNC) such as Uber and Lyft for vehicle staging. Previous
authorizations supported the construction of permanent lighting systems, restrooms, security
cameras, landscaping, and electrical infrastructure upgrades supporting the installation of ten
electrical vehicle (EV) fast charging points. This work has been completed. The original project
scope assumed a partnership with EVgo to supply and install the equipment and software,
provide maintenance and operational support, and other general management tasks for the EV
fast charging points. Both the electrical infrastructure upgrades and the EV fast charging points
were partially funded by a Department of Commerce (DOC) grant.
After the grant was awarded, the Port and EVgo began lease negotiations. Ultimately the Port
and EVgo could not reach agreement on the lease terms and the partnership with EVgo was
terminated. To support the Commission’s Ground Transportation Policy Directive (Resolution
no. 3759, adopted in July 2019), take advantage of the available grant funds, and complete the
installation of the EV fast charging points the Port needs to change delivery methods instead of
relying on a third-party partner. This authorization request supports the purchase and
installation of EV equipment and software to complete the installation of the EV fast charging
points by the Port.

JUSTIFICATION
This project supports the following Century Agenda goals:
• To advance this region as a leading tourism destination and business gateway by
meeting the region’s air transportation needs by delivering vital facilities and
infrastructure in a sustainable and cost-effective manner.
• To be the greenest and most energy-efficient port in North America by reducing air
pollutants and carbon emissions.
To become a model for equity, diversity, and inclusion by increasing utilization of
Women and Minority Business Enterprise (WMBE) and Disadvantage Business
Enterprise (DBE) firms and eliminating disparity of access to opportunities.
Diversity in Contracting
The design of this project utilized an existing indefinite delivery indefinite quantity (IDIQ)
contract that has a Women and Minority-Owned Business Enterprise (WMBE) commitment of
fifteen (15) percent. The construction of this project included a WMBE commitment of ten (10)
percent.
DETAILS
The Port has an agreement with the TNC partners to improve the operating conditions for
drivers and support sustainability improvements between the parties. The EV chargers and
permanent restrooms support this agreement, and equity goals and helps deliver sustainability
improvements as documented in a December 10, 2020, letter from the Managing Director of
Aviation to the TNC partners.
The project will install ten EV fast charging points utilizing a $1.2 million DOC grant that partially
funds the installation of the EV chargers and the required electrical infrastructure upgrades.
The project team intends to utilize a Washington State Department of Enterprise Services
contract to procure the EV chargers and software subscriptions, and to provide operational and
maintenance support. The change in project scope and approach has been reviewed with DOC
and they support the changes and will extend the grant funding through year-end 2025. Port
Construction Services will also be utilized to provide some site improvements supporting the
installation of the EV chargers.
Scope of Work
Most of the project improvements have been completed. Permanent lighting systems have
been installed replacing the temporary diesel-powered temporary light plants. Four permanent
restrooms and security cameras have been installed supporting TNC operations. Electrical
infrastructure upgrades have been completed supporting the permanent lighting and the EV
chargers. Landscaping improvements were completed in accordance with the Port’s
landscaping standards. The remaining scope of work includes the installation of ten EV fast
charging points and site improvements to support the installation.

Financial Analysis and Summary
Project cost for analysis $8,400,000
Business Unit (BU) Ground Transportation
Effect on business performance
(NOI after depreciation)
NOI after depreciation will decrease
IRR/NPV (if relevant) N/A – No additional revenues are anticipated from this
investment.
CPE Impact N/A
Future Revenues and Expenses (Total cost of ownership)
As a result of this project, we anticipate moderate impacts resulting in increased annual O&M
costs. The new restrooms will add additional costs for custodial services and maintenance. The
expanded landscaping will also result in a minor increase to landscape maintenance costs. The
EV fast charging points will add additional costs for the maintenance and operational
agreements and will require Port oversight to manage.
Ground transportation operators will pay a fee to use the ten EV fast charging points once
installed. Port staff anticipate setting the fee at a competitive market rate and those revenues
are anticipated to offset the cost of the EV fast charging points.
