DATE:    July 17, 2015

SUBJECT: One Year Extension to TSA Mezzanine Training Space Lease 

ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to execute Lease Amendment
No. 2 (Attachment 1) of the existing Mezzanine Lease (Exhibit A) with the Transportation
Security Administration represented by the General Services Administration (TSA).  This
amendment extends the term of the lease for one additional agreement year and increases the
rental rate. 
SYNOPSIS 
TSA has a lease for a training room located, pre-security, on the Mezzanine Level of the Main
Terminal which expires September 2, 2015. TSA is currently working to improve their training
efficiency by consolidating several training rooms, currently spread across the Airport. To do
this, TSA has developed a tenant improvement project to consolidate these training functions
post-security, but they need a one year lease extension to give them time to complete required 
renovations. 
BACKGROUND 
TSA has significant leased space throughout the Airport under three separate leases with the
Port. Those three leases are commonly known as the Mezzanine Lease (1,844 square feet (sf)),
Main Lease (8,338 sf) and C1 Building Lease (10,756 sf) for a total of 20,938 sf 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.  Three leases exist because they were
negotiated and occupied at three separate points of time, as well as some other key conditional
lease terms. 
The Mezzanine Lease was effective on September 3, 2008, and encompassed both an office area
(1,924 sf) and a training area (1,844 sf). In September 2013, the Mezzanine Lease was amended

Template revised May 30, 2013.

to extend the term to September 2, 2015 and to reduce the area leased to 1,844 sf. TSA staff is in
the process of designing a reconfiguration of the space TSA occupies in the C1 Building to
include and consolidate this training function. A future Commission action will be necessary to
approve the reconfiguration of space and add some additional square footage leased by TSA 
under the C1 Building lease. Approving this lease extension provides TSA the time it requires to
reconfigure the space it leases in the C1 Building with the intent to consolidate the training
function in the reconfigured C1 Space.
LEASE SUMMARY COMPARISON 
Below is a comparison of the key business terms of the current lease and amended lease. 
Current Lease Terms        Proposed  Amended  Lease
Terms 
Term                9/3/2008-9/2/2015        9/3/2015-9/2/2016 
Premises (Square Feet)      1,844 sf                Unchanged 
Monthly Rent            $15,007.08             $17,258.30 
Option to Terminate                            At the commencement of the
7th month of the lease term,
Lessee will have the option to
terminate the lease with 30
days prior written notice 
FINANCIAL IMPLICATIONS 
By extending this Lease for one additional year, and increasing the negotiated rental rate by 15%
to $112.31/sf/yr., the Port will realize an increase in revenue of $27,014.64 during the lease
extension. The lease rate at $112.31 aligns with the GSA lease rate on 10,756 square feet in the
C1 Building. This lease extension does not financially obligate the Port in any measurable way. 
STRATEGIES AND OBJECTIVES 
The action supports our strategy to operate a world class international airport by insuring safe
and secure operations. We achieve this objective through assisting our TSA partners in
acquiring office space and facilities to facilitate improved security at the Airport. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 

Alternative 1)  Allow the lease to terminate and require the tenant to vacate as prescribed in the
underlying lease.

Pros: 
Vacation of the mezzanine space at the expiration of the current term would add
inventory to available space for lease to another tenant one year earlier. 
Cons: 
The TSA would be put into a difficult position, without adequate space to operate and
train their staff. 
The Port would lose the opportunity to extend the revenue stream for an additional year. 
This is not the recommended alternative. 
Alternative 2)  Allow the lease to expire and tenant to stay provisionally in a holdover state.
Pros: 
Allows TSA to remain in its current space without interruption until the C1 Building
reconfiguration is complete.
Cons: 
A holdover situation would maintain the lease terms as currently written, including the
lower lease rate of $97.66/sf/yr. and the revenue stream would be on a month to month
basis. 
We endeavor to avoid holdover situations whenever possible. 
This is not the recommended alternative. 
Alternative 3)  Execute the one-year lease extension.
Pros: 
Allows TSA the time it needs to complete its reconfiguration of the space it occupies in
the C1 Building and to relocate the training space currently located on the mezzanine
level.

COMMISSION AGENDA 
Ted J. Fick, Chief Executive Officer

Cons: 
Would not align with the Port's partnership with TSA to support its efforts to reconfigure
the space it leases in the C1 Building with the intent to consolidate the training function
in the reconfigured C1 Space. 
This is the recommended alternative.
