ACTION REQUESTED 
Request authorization for the Chief Executive Officer to execute an Operations and Maintenance
Agreement with Sound Transit to establish responsibilities at the Airport Station at Seattle-
Tacoma International Airport (Airport). 
SYNOPSIS 
Sound Transit"s Airport Link will be operational by the end of the year. Various operational and
maintenance issues have been coordinated between Sound Transit and the Airport to implement
the service at the Airport Station to/from the Airport terminal. Agreed-upon responsibilities will
provide clarity in roles and obligations. 
BACKGROUND 
On April 11, 2006, the Commission approved the Second Reading and Final Passage of
Resolution No. 3559, as Amended, to execute an Interlocal Agreement with Sound Transit to
establish the real property, financial and construction arrangements for construction of the
Airport Link Project at the Airport. Construction of Airport Link, including the Airport Station, 
is near completion and scheduled to be in operation no later than December 19, 2009.
Operations and maintenance impacts of Sound Transit"s Link Light Rail system constructed on
or over Port of Seattle (Port) property have been identified and agreement has been reached on
responsibilities and procedures. Essentially, the Port will be financially responsible for
operations and maintenance of Port assets, and Sound Transit will be financially responsible for
operations and maintenance of Sound Transit assets.

Two cost transactions are identified in the Operations and Maintenance Agreement. First, Sound
Transit has requested that the Airport provide reimbursable landscape maintenance services
within their Light Rail Transit Way Easement. Second, Sound Transit will provide electrical
service to the Airport"s pedestrian bridge, to be reimbursed by the Airport. Both items will be
reimbursed based on actual costs, and will affect annual operating expense budgets. 
PROJECT DESCRIPTION/SCOPE OF WORK 
Project Statement: Execute an "Operations and Maintenance Agreement" between Sound Transit
and the Port of Seattle. 
Project Objectives: Clarify responsibilities for assets and operational coordination. 
Scope of Work: Identify interface dependencies and collaborate to efficiently implement
operations and maintenance. Document the negotiated agreement. 
The Airport will maintain its own large landscaped areas along the Airport-owned expressways.
The Airport will also maintain Sound Transit"s smaller landscaped areas near its station, along
the guideway, and at the traction power substation site on International Boulevard, and will be
reimbursed by Sound Transit for that work. Sound Transit has nearby electrical power to serve
the Airport pedestrian bridge between the station and garage. The Airport will reimburse Sound
Transit for the actual cost of that power. 
STRATEGIC OBJECTIVES 
This effort supports the Port"s strategy to "Be a Catalyst for Regional Transportation Solutions." 
FINANCIAL IMPLICATIONS 
In current 2009 dollars, the estimated reimbursable landscape maintenance cost is $12,000/year
including a 15% administrative fee, and the Airport electrical service cost is estimated at
$3,000/year. The Airport will be incurring $15,000/year in new operating costs, of which 
$12,000 will be reimbursed. 
ENVIRONMENTAL SUSTAINABILITY/COMMUNITY BENEFITS 
The Airport is leveraging its infrastructure investments in collaboration and partnership with
Sound Transit to ensure long-term effective public access that is key to the Airport's and the
region's future success. Light rail service provides a transportation mode that is an
environmental benefit to the region.

TRIPLE BOTTOM LINE SUMMARY 
Consolidating Sound Transit"s landscape maintenance scope with the Airport"s will provide cost
efficiency, consistent quality, and minimize environmental impacts. 
PROJECT SCHEDULE 
Sound Transit"s Airport Link will be operational no later than December 19, 2009. Agreement
term is five (5) years. 
ALTERNATIVES CONSIDERED/RECOMMENDED ACTION 
Sound Transit executes landscape maintenance in their Light Rail Transit Way Easement.
This option is a slightly higher cost to Sound Transit, and would require coordination for
consistent performance. This is not the recommended alternative. 
Airport provides electrical service to the Airport pedestrian bridge. This would require
design and construction modifications, increasing the costs. This is not the recommended
alternative. 
Provide reimbursable services for landscape maintenance in the Light Rail Transit Way
Easement, and electrical power to the Airport pedestrian bridge. This is the
recommended alternative.
