SUBJECT:  North Expressway Final Paving, Landscaping, and Reclamation. CIP C800034 
AUTHORIZATION REQUEST: $0        SOURCE OF FUNDS: Revenue Bonds 
SALES TAX PAYOUT: $180,000         CONSTRUCTION JOBS: 120 
ACTION REQUESTED: 
Request authorization for the Chief Executive Officer to advertise for bids and award a
construction contract for the North Expressway Relocation Phase 1 project consisting of final
paving, landscaping and reclamation. The estimated cost of this project, $5,880,000, is within the
previously authorized budget. 
SYNOPSIS: 
The North Expressway Relocation Phase 1 program consists of relocation of the northbound
lanes, the northern section of the southbound lanes, and associated ramps for the North Airport
Expressway (NAE) in multiple phases. A subsequent and currently unprogrammed North
Expressway Relocation Phase 2 project will complete the relocation of the southbound lanes. 
This project is a part of the larger North Expressway Relocation Phase 1 program. The project
will perform final paving, restoration, and reclamation work associated with the relocation of the
NAE and the extension of light rail transit (LRT) to the airport. This project is the last of seven
phases to relocate the NAE and bring LRT to the airport. This seventh contract will utilize a
Project Labor Agreement. The project completes the Port's obligations to Sound Transit to
facilitate extending LRT to the airport and to the City of SeaTac for landscaping of Port property
and restoration of facilities along city streets. Both the Port's relocated NAE and Sound
Transit's LRT are in operation. Budget has already been authorized that is sufficient to cover
construction of this contract.

BACKGROUND: 
Previous projects to relocate the NAE and extend LRT to the airport were accomplished in
multiple phases in collaboration with Sound Transit. This contract follows the major contracts
that are complete or will be complete in the near future. The timing of the contract will allow the
work to occur during the optimal seasonal construction period. The contract consists of the
completion of ramps adjacent to the Airport Station and parking garage, a north entry art feature,
landscaping, work deferred in order to facilitate construction of the major contracts, and
restoration and reclamation of work areas. Sound Transit will reimburse the Port for portions of
the work that are their cost responsibility. The Memorandum of Agreement entered into on April
17, 2006 between Sound Transit and the Port lists this project as the last phase of the multi-phase
program.
PROJECT DESCRIPTION/SCOPE OF WORK: 
Project Statement 
This project is the last phase of a multi-phase program to construct facilities to minimize
congestion of the terminal drives and to provide a corridor and supporting infrastructure that
enabled Sound Transit to begin LRT operations to Seattle-Tacoma International Airport by the
end of 2009.
Project Objectives: 
Provide roadway facilities and supporting infrastructure that are compatible with future
Airport development and implementing light rail transit. 
Minimize impacts to Airport operations during construction. 
Minimize the Port's capital investment and operational and maintenance costs. 
Minimize the impacts to other Port capital improvement projects. 
Provide a roadway system that operates at an acceptable level of service with excellent
customer way finding. 
Meet tenant and operator relocation requirements. 
Provide a comprehensive communication plan for both internal and external stakeholders. 
Scope of Work: 
The project includes final paving of ramps near the parking garage entrance and airport station,
landscaping, an art feature and clock tower at the Airports north entrance, reclamation of staging
and work areas, and miscellaneous work omitted or deferred from previous North Expressway
Relocation Phase 1 contracts.

The project will be bid and constructed as a single, major capital contract and will provide an
estimated 120 short-term construction jobs during the course of the contract. 
STRATEGIC OBJECTIVES: 
This effort supports the Port's strategy to "Be a Catalyst for Regional Transportation Solutions".
The work to support LRT access to the airport results in an additional mode of transportation for
airport patrons and employees. 
FINANCIAL IMPLICATIONS: 
Capital Budget/Authorization Summary: 
The project has previously received Commission funding authorization of $102,436,000 and
contract authorization for $165,000,000. The higher contract authorization amount allowed
portions of Sound Transit's LRT to be included in contracts administered by the Port. Budget
transfers to include electrical work from another project, art elements, Port assets paid by Sound
Transit, and savings have occurred for a current revised budget of $110,487,700.

revenue from the airlines will not cover the estimated debt
service, generating a negative cash flow of $4.5 million
annually. NOI after depreciation will decrease by
approximately $200,000 annually.

SUSTAINABILITY AND LIFE CYCLE COSTS: 
The North Expressway Relocation project has relocated roadways and changed the vehicular
circulation pattern to minimize traffic congestion and allow the extension of LRT to the airport. 
This contract contains features that are designed to minimize future maintenance, such as the use
of concrete barriers; minimal use and coating of galvanized material to enhance water quality; 
and the reclamation and landscaping of sites disturbed by the construction. The north entry art
feature includes LED lighting and solar panels. The features are designed for an appropriate
service life and to minimize future costs. 
TRIPLE BOTTOM LINE: 
The completion of the NAE relocation and LRT project will continue to support the positive
long-term economic impacts of the Airport, and provide a community benefit through the
addition of high capacity transit to the Airport. 
PROJECT SCHEDULE: 
Startup of LRT operations at the Airport  December 2009 
Bid and Award: January 2010 to March 2010 
Construction and commissioning: April 2010 to December 2010 
Punch list and closeout: December 2010 to February 2011 
First year plant establishment: December 2010 to December 2011 
ALTERNATIVES CONSIDERED/RECOMMENDED ACTION: 
A. Do-Nothing  Under this alternative, the Port does not undertake any additional
improvements to complete the north entrance and exit to and from the parking garage,
landscaping in areas that border city streets and an art feature at the airports north
entrance. The project would not be complete, ramps to and from the parking garage
would be left unfinished, the north roadway entry would not be enhanced, the Port would
be non-compliant per agreements with the City of SeaTac, and the Port would not fulfill
its obligation under the Memorandum of Agreement (MOA) with Sound Transit. Sound
Transit would be required to complete landscaping along International Boulevard in front
of their traction power substation, fall protection above a wall, and other miscellaneous
work by a separate contract. This is not the recommended alternative. 
B. Complete the Paving, Landscaping, and Reclamation.  Under this alternative, a finished
project would occur for the previous roadway relocations including site reclamation of
work area. Both the Port and Sound Transit would meet their landscaping commitments
to the City of SeaTac. Sound Transit would be a participant in a portion of the costs.
This is the recommended alternative.
