FROM:    Laurel Dunphy, Director, Airport Operations

SUBJECT:  South 160th Street Lot Transportation Network Company Improvements (C801186) 
Amount of this request:               $1,417,000 
Total estimated project cost:          $7,300,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to complete design and execute
utility  agreements  for  the  South   160th   Street   Lot  Transportation  Network  Company 
Improvements project at Seattle-Tacoma International Airport in the amount of $1,417,000. The
total estimated project cost is in the amount of $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 typically found in modern parking and ground transportation
facilities, while improving use and safety during vehicle staging. The project also includes the
addition of ten new electric vehicle (EV) chargers for the TNC fleet through a Department of
Commerce grant, which supports the Port's environmental goals.  In addition, permanent
restroom facilities will be provided 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.

COMMISSION AGENDA  Action Item No. 8g                                   Page 2 of 5 
Meeting Date: September 28, 2021 
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 will utilize an existing indefinite delivery indefinite quantity (IDIQ)
contract that has an established WMBE aspirational goal of 10%. The project team will work with
Diversity in Contracting department to establish additional WMBE aspirational goals within the
construction phase of this effort. 
DETAILS 
The project will install ten EV chargers using approximately $1.2 million of grant funds awarded
by Department of Commerce (DOC). The grant is currently conditionally approved by the DOC. A
tenant lease agreement is being negotiated between the Port and the third-party entity EVGo to
own and maintain the EV chargers. The lease agreement will need approval from the DOC once
it is finalized. The grant will be awarded through reimbursement and the grant conditions will
require the completion of this reimbursement, by May 2024. Since, the DOC will only work with
the Port as the applicant for the grant reimbursement, the cost of the EV chargers must flow
through the Port before being reimbursed. 
The Port has agreements 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 help deliver sustainability improvements 
as documented in a December 10, 2020 letter from the Managing Director of Aviation to the TNC
partners. 
The project budget has increased from $3,728,000 to $7,300,000. This budget increase is due to
the addition of the restrooms  and security cameras, required landscaping and irrigation 
improvements, administrative error setting the original budget (using the wrong estimate), and
the cost of the EV chargers that will be reimbursed through the grant. 
There are some risks and opportunities associated with this project. Additional lighting poles, or
the replacement of existing lighting poles, may be required to meet current requirements.
Additional restroom facilities may also be required to support TNC operations. The project may
also qualify for a sale tax exemption under the Washington Administrative Code. These will be
addressed during the design phase of the project.

Meeting Date: September 28, 2021 
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 for EV
use in the TNC fleet. The project will also install two 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.

Future Revenues and Expenses (Total cost of ownership) 
As a result of this project, Aviation Maintenance anticipates moderate impacts resulting in
increased annual O&M costs. The new restrooms will add additional costs for custodial services,
interior/exterior maintenance, and mechanical systems. The expanded landscaping will also
result in a minor increase to landscape maintenance costs.
