SUBJECT:  Property acquisition from and guideway easement for Sound Transit for future
South Access to the Airport (CIP #C800143). 

Amount of this request:               $3,335,746 
Total estimated project cost:           $3,335,746 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to execute and deliver a purchase
and sale agreement and all necessary documents to acquire property near Seattle-Tacoma
International Airport on 28th Avenue South from Sound Transit and execute and deliver a
guideway easement for their existing light rail operation in this location for an approximate cost
of $3,335,746. 
EXECUTIVE SUMMARY 
On August 15, 2012, the Port of Seattle executed a Memorandum of Agreement (MOA) with
Sound Transit that granted permanent easements and the sale of several parcels of land for the
development of Link Light Rail from Seattle-Tacoma International Airport (Airport) to South
200th Street. One of the properties acquired by Sound Transit is on Air Cargo Road adjacent to
the Wally Park parking structure. Sound Transit entered into a condemnation action with Wally
Park for property they needed and property needed by the Port, all of which will ultimately be
needed by the Port for South Access to the Airport. Sound Transit agreed to sell the property,
in fee, when it was no longer needed as laydown for their construction. The Port agreed to pay
the proportionate share of the condemnation action, because it provided critical property for
the future South Access.
A small additional parcel of land, not originally considered in the MOA, is valued at $145,000
based upon a recent appraisal completed in April 2018, so the total acquisition payment to
Sound Transit is $3,335,746. Furthermore, the Port will grant a permanent easement to Sound
Transit for the guideway of the light rail system over the property, which was part of the MOA

agreement with Sound Transit. In consultation with Airport Planning, the need for this property
remains unchanged.
This land acquisition is included in the 2019  2023 capital budget and plan of finance with a
budget of $3,394,746. 
JUSTIFICATION 
This action supports the Century Agenda goal to "meet the region's air transportation needs for
the next 25 years" by reserving land needed to enhance passenger access to and from the
Airport and providing relief to the North Airport Expressway. 
DETAILS 
In 2012, the Port was analyzing the alternatives for South Access from SR-509 to the airport. It
was apparent, even at this early stage, that the property Sound Transit was acquiring for
guideway and laydown requirements for the building of Link Light Rail, from the Airport to
200th, would ultimately be needed for South Access even though a specific route has not been
determined.  As part of the MOA negotiations, Sound Transit agreed to acquire additional
property, that moved the guideway alignment further east, and then sell the property to the
Port for the proportionate cost of acquisition/condemnation upon completion of construction.
The agreement was memorialized in the MOA that was subsequently approved by Sound
Transit Board of Directors and the Port Commission.
At that time, the Airport was planning to connect the airport to what will become the freeway
extension of SR 509 to I-5.  However, the project was not far enough along to warrant a
condemnation action by the Port.  South Access is the long-range plan to connect the new
extension of SR 509 to I-5 to the Airport. Sound Transit agreed, in their condemnation action,
to acquire sufficient property to accommodate the South Access plans. The property acquired
by Sound Transit allowed their guideway to be located further to the east, which would not
conflict with the space needed for the future South Access. 
In Addition, Sound Transit wants the Port to acquire a sliver of land that was not envisioned
during the planning phase but was created by the actual construction. The Port acquisition of
the property, under the MOA, causes the Sound Transit's remainder site to become inaccessible
after acquisition. The value of the small parcel is $145,000 based upon appraisal submitted in
April 2018. 
The Port will grant Sound Transit a permanent easement in the same format as the balance of
their guideway easements over Port property for their existing guideway. 
Scope of Work 
Sign all necessary documents for the purchase of the land and providing a guideway easement.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  The Commission could decide not to purchase the properties. 
Cost Implications: This would save $3,335,746. 
Pros: 
(1)   The Port would not have to pay out $3,335,746. 
(2)   The Port could wait and acquire the property through condemnation once a South
Access project is approved. 
Cons: 
(1)   The action would be inconsistent with the parties' respective commitments under the
2012 MOA. 
(2)   Sound Transit could seek to compel the Port to purchase the property pursuant to the
terms of the MOA. 
(3)   It  would  not  provide  potential  laydown,  in  the  interim,  for  projects  like  the
International Arrivals Facility. 
(4)   This would prevent the Port from acquiring critical land for the potential future South
Access to the airport. 
This is not the recommended alternative. 
Alternative 2  Purchase the property from Sound Transit. 
Cost Implications: $3,335,746 
Pros: 
(1)   This would be consistent with the commitment under the MOA. 
(2)   It would provide potential laydown, in the interim, for projects like the International
Arrival Facility. 
(3)   It would ultimately provide sufficient land for the future South Access to the Airport. 
Cons: 
(1)   It would cost the airport $3,335,746. 
This is the recommended alternative.

Annual Budget Status and Source of Funds 
This project was included in the 2019 - 2023 capital budget and plan of finance with a budget of
$3,394,746 (CIP #C800143).  The funding source will be the Airport Development Fund.  The
property is being acquired to accommodate the South Access project that will connect the
Airport to the extension of SR 509 and I-5.  Initially, the property is not expected to generate
incremental revenue.  Upon completion of South Access, a portion of the costs of this land
acquisition may be allocated to airline rate bases through the roadway cost allocation, and thus
generate some revenues.
