MAJOR PROJECT AUTHORIZATIONS 
North Satellite 
and 
International Arrivals Facility

Seattle and Sea-Tac Face Challenges,
but Are Envy of Other Cities /Airports 
Fastest growing U.S. city (of top 50) 
Increasingly internationally-oriented
economy 
Hometown airline (Alaska) quite profitable 
Principal international airline (Delta)
building major Asian gateway

Growth at Sea-Tac Airport 
Among fastest growing airports in the U.S.* 
Most recent 12 months  4.8%, 2nd fastest 
One of fastest growing international airports 
2013: 10.2%, 2nd fastest 
2012: 8.8%, 5th fastest 
Century Agenda: Double international flights
and destinations in 25 years 
Have already added five intercontinental
destinations in first 4 years, 40% toward goal. 
*comparisons to top 20 busiest U.S. airports 
3

Growth at Sea-Tac Airport 
Delta: 
December, 2014 - 95 daily departures vs. 35 in
2013 
Projects 150 daily departures in 2017 
Has added six intercontinental destinations
since 2007 
Alaska: 
Added 8 daily departures in past 12 months 

4

Growth at Sea-Tac Airport 
Master Plan Forecast: 
Preliminary analysis indicates DL/AS growth
projections are sustainable -- reasonable growth
expectations for five year period; will eventually
revert to more modest growth 
In line with what has happened at other airports 
Staff will provide full briefing in August 
Facilities Planning: 
Must start focusing on post-NorthSTAR needs

management response -- 
IAF cost increases by $122M ($316M to $416M
in Phase I and $28M to $50M in Phase II) 
NorthSTAR cost increases by $50M 
Reduce other capital spending by $172M

Connector Contracting 
Benefits of contracting the design and
construction of the IAF and Connector
together include: 
Simultaneous coordination of design and
construction 
Management by a single team 
Allows faster completion for both airlines and
travelers 
Reduces construction coordination and other
risks

IAF Connector Evaluation Criteria 
Passenger Experience 
Capacity/Future Flexibility 
Construction Impacts 
Capital Cost 
Maintenance Cost 
Risk 

10

Evaluation Criteria     Bridge                             Tunnel 
Passenger Experience     Natural Light                       More lighting necessary 
Unique views: airfield activity       Interior finishes more
and mountains                      important 
More intuitive way finding          More vertical transitions 
Longer passenger route 
Capacity/Future          Smaller ramp footprint              Larger ramp footprint 
Flexibility                    Wider profile allows 2 way            Could limit STS expansion 
passenger flow

Evaluation Factor        Bridge                             Tunnel 
Taxi-lane and Gate       12 months                       18 months 
Impacts 




Initial Capital Cost         Lower                               Higher 
(estimated $12-17M) 

On-going               Slightly higher                 Slightly lower 
Maintenance Cost         (estimated $15-30K/yr) 

12 12

Evaluation Factor       Bridge                             Tunnel 
Risk                       Scale/Height                       Contaminated/soft soil 
conditions 
Utilities disruption 
Work under active taxi-lane 
More construction traffic on
ramp (soils hauling) 






13

Summary: Bridge is Best Option 
Passenger Experience 
Offers a better passenger experience 
Offers a unique opportunity: image and views 
Capacity/Future Flexibility 
Yields a smaller footprint 
Offers opportunity for future two way travel 
Construction Impacts 
Effects less impact to airport operations 
Capital Cost 
Is more cost effective 
Maintenance Cost 
Is minimally more 
Risk 
Presents less risk
