DATE:     February 6, 2023

FROM:    Laurel Dunphy, Director of Airport Operations

SUBJECT:  S. 160th St TNC Lot Improvements (CIP# 801186) 
Amount of this request:               $6,083,000 
Total estimated project cost:          $7,300,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to advertise, award, and execute a
construction contract, and authorize an additional $6,083,000 for the South 160th Street TNC Lot
Improvement Project at Seattle-Tacoma International Airport. The total estimated project cost
is $7,300,000. 
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. Currently,
permanent lighting is installed in the holding lot area used by taxis, as opposed to the TNC lot
area which has temporary diesel-powered lighting. Approval of this project would install
permanent lighting systems, ten new electric vehicle (EV) chargers for the TNC fleet partially
funded by a Department of Commerce (DOC) grant, and four permanent restroom facilities to
support TNC operations.
JUSTIFICATION
This project will support 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.

Meeting Date: February 14, 2023 

Diversity in Contracting
Project staff along with the Diversity in Contracting Department have set a women and minority
business enterprise (WMBE) aspirational goal of 10% for this construction contract. 
DETAILS 
The project will install ten EV chargers utilizing a $1.2 million grant awarded by the DOC that
partially funds the installation of the EV chargers and the required electrical infrastructure
upgrades. A lease will be required between the Port and the third-party entity EVgo who will 
own, operate and maintain the EV chargers. The lease may require future authorization by the
Commission once negotiations are completed, and the DOC has approved the terms.
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. 
Scope of Work
The project will install permanent lighting systems in the TNC portion of the GT lot and replace
the existing diesel-powered temporary light plants. The project will also add 10 EV charging
stations and their supporting infrastructure on the TNC side, which supports the Port goal to
reduce greenhouse gas emissions from passenger ground transportation, including the TNC fleet.
The project will also install four permanent restrooms for TNC operators, security cameras for
operational awareness, and expand the landscaping areas throughout the GT lot as required by
permitting and current landscaping standards.

This project (CIP #C801186) was included in the 2023-2027 capital budget and plan of finance
with a budget of $6,586,000. A capital budget increase (no change to total project budget) of
$204,000 was transferred from the Non-Aeronautical Allowance (CIP #C800754) for a total
revised capital budget of $6,790,000 resulting in zero net change to the Aviation capital budget.
The funding sources will be grants, Airport Development Fund (ADF)and revenue bonds. The
Department of Commerce grant will reimburse up to $1,229,322.42 of the project costs with up

Future Revenues and Expenses (Total cost of ownership) 
As a result of this project, we anticipate moderate impacts resulting in increased annual O&M

expanded landscaping will also result in a minor increase to landscape maintenance costs.
