Sustainable Airport Master Plan Near-Term Projects

Planning to accommodate airport need by 2027

The Sustainable Airport Master Plan’s Near-Term Projects provide the blueprint for changes at SEA to meet forecast demand over the next 10 years. The suite of proposed projects works to accommodate airport need, all while improving efficiency, safety, access to the airport, and support facilities for the airlines and the airport.

While current projects reduce congestion and improve efficiency for today's travelers, it’s also important to plan for tomorrow. The Sustainable Airport Master Plan documents the airport's plans to serve the region. The plan focuses on serving the residents and visitors who will be here in future decades while preserving resources and advancing sustainability.

To develop its Sustainable Airport Master Plan, the Port made sustainability priorities, such as reducing impacts to wetlands, proximity to noise, and light-sensitive land uses, part of the criteria for evaluating planning concepts. This is one of the ways the airport is working towards the Port Commission’s goal to be the greenest, most energy-efficient port in North America.

Growing region, growing airport. It’s essential to have a blueprint for the future

Specifically, these Near-Term Projects will address forecast demand through 2027, while a Long-Term Vision will cover later years.

These proposed Near-Term Projects all fit within the framework of environmental best practices and fiscal discipline. Significant investments would include: a new terminal with 19 gates, a people mover, reconfigured roadways to improve efficiency and access to the airport and improved safety and support for airlines and airport operations. The planned projects are designed to meet forecasted passenger and cargo demand, comply with the Federal Aviation Administration (FAA) airfield standards and guidance, improve airfield operational efficiency, and provide additional fuel capacity to support the Port’s Sustainable Aviation Fuel Initiative.

The Near-Term Projects are currently undergoing environmental review. To learn more, visit www.SAMPNTPenvironmentalreview.org.

Environmental Review

In December 2019, the environmental review period was extended to incorporate feedback received during environmental scoping.  Environmental review will include additional topics that the public raised during the scoping period, update the 2014 demand forecast to reflect the rapid growth that occurred in the last few years, and complete the NEPA and SEPA analysis separately and sequentially. This is a working schedule and deliverable deadlines and dates may shift due to unforeseen circumstances. The FAA will not issue an environmental finding until all NEPA requirements are satisfied.

Project Fact 1
Population increases in the cities of Seattle, Kirkland, Kent, Bellevue, and Burien will impact air travel.
Project Fact 2
Plans for 19 gates at a new second terminal and reconfigured roadways will meet market demand.
Project Fact 3
Additional projects are designed to improve safety and airline support on the runways and taxiways.
Project Fact 4
One major project expands the airport fuel farm to create sustainable aviation fuel storage and blending space.
