PORT OF SEATTLE 
MEMORANDUM 
COMMISSION AGENDA               Item No.      5e 
ACTION ITEM 
Date of Meeting     October 8, 2013 
DATE:    September 18, 2013 
TO:      Tay Yoshitani, Chief Executive Officer 
FROM:   James R. Schone, Director, Aviation Business Development 
James Jennings, Manager, Aviation Properties 
SUBJECT:  Two-year Extension to TSA Mezzanine Training Space Lease 
ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to execute Lease Amendment
No. 1 (Attachment 1) of the existing Mezzanine Lease (Exhibit A) with the Transportation
Security Administration represented by the General Services Administration (TSA/GSA). This
amendment extends the term of the lease for two additional agreement years and reduces the
leasehold from 3,768 square feet to 1,844 square feet.
SYNOPSIS 
The TSA/GSA has reached the end of its lease term for a portion of its leased space on the
Mezzanine Level of the Main Terminal. Because of increased airline demand for this office
space located prior to security, the Port is working to find an alternate location for these TSA
functions. The amendment is for only two years, which should provide adequate time to identify
and prepare a new location for the TSA beyond the security checkpoint. 
This lease expired on September 1, 2013. Although the TSA/GSA and the Port had been in
discussions on the anticipated expiration of this lease for some time, Port staff did not receive the
proposed amendment until August 23, 2013.  Due to a delayed response, which requires 
Commission action, this lease will briefly be in a holdover status until the amendment is
executed.
BACKGROUND 
The TSA/GSA has three separate terminal space leases with the Port. Those three leases are
commonly known as the Mezzanine Lease (3,768 sq. ft.), Main Lease (8,338 sq. ft.) and C1
Building Lease (10,756 sq. ft.) for a total of 22,862 sq. ft. of leased space. The functions of these
spaces vary between office, break room and training in support of their security checkpoint and
baggage screening duties, and were not consolidated because of differences in timing of their
leasing as well as differences in terms related to the condition of space and associated differences
in the Port's level of investment.

The Mezzanine Lease was effective on September 3, 2008, and encompassed both an office area
(1,924 sq. ft.) and a training area (1,844 sq. ft.). The Port initially indicated its intention to let
this lease expire because the space is needed to accommodate airline functions, but the tenant has
requested to retain the training area for two additional years and return only the office area while
a suitable location for their training functions is identified and prepared. It is the Port's plan to
locate the TSA training space post-security, where there is more available space and a reduced
likelihood of conflict with airline needs. A future Commission action may be necessary to fund
landlord related improvements to support this future relocation.
FINANCIAL IMPLICATIONS 
By extending this Lease for two additional years, reflecting the decrease in leased premises, the
Port will secure an estimated $360,170 of revenue from the two-year lease extension. This lease
extension does not financially obligate the Port in any measurable way.

STRATEGIES AND OBJECTIVES 
This lease supports the Century Agenda strategy of advancing the region as a leading tourism
destination and business gateway. This helps the TSA/GSA continue to support Port of Seattle
staff in operating a safe and secure airport, while also meeting the region's air transportation
needs at Sea-Tac. 
This amendment also supports the Aviation Division's strategic goal of operating a world-class
international airport. It allows the TSA/GSA to continue to provide a high level of customer
service to airlines and their passengers and to keep the Airport operating smoothly by ensuring
that the TSA workforce is properly staffed and administratively supported.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1)  Allow the lease to terminate and tenant shall vacate as prescribed in the
underlying lease. This would remove a critical training area from the TSA that would hamper
their ability to keep their workforce trained and meet federal requirements.  This is not the
recommended alternative. 
Alternative 2)  Allow the lease to expire and tenant to stay provisionally in a holdover state.
This is not the recommended alternative. 
Alternative 3)  Execute the two-year lease amendment. This will secure a continued flow of
revenue for the Port and allow TSA/GSA adequate time to design and construct a new training
space post-security. This is the recommended alternative.
