– Alternatives analysis for major plan elements • Advanced planning - in progress – More detailed planning in focus areas of long-range plan and existing facilities – Alternatives analysis within individual projects (e.g. options for configuring curbs and functional areas for Second Terminal) • Preliminary design - current capital funds request – Program development for individual projects – Adequate detail required to transition projects to design – Results in a Project Definition Document (PDD) Near-Term Projects Near-Term Projects Design/construction period estimates for major projects NOTE: Preliminary design precedes design phase shown above and is not depicted. Commission authorization is required to proceed into design 1) Westside Maintenance Campus 2) Aircraft Rescue and Fire- Fighting (ARFF) Relocation 3) Roadway Improvements 4) Taxiway A/B Extension 5) Main Terminal North GT Lot Projects Requiring Preliminary Design Design/construction period estimates Glideslope Antenna Relocation • Taxiway A/B project requires relocation of Runway 34R glideslope antenna – Opportunity to adjust slope angle and increase aircraft elevation on approach – Sea-Tac Stakeholder Advisory Round Table (StART) recommendation • Relocate to potentially permanent location (i.e. consistent with Taxiway A/B project) • Attempt to obtain a 3.1˚ glideslope angle • Look for ways to expedite the project – Begin design (design at risk prior to conclusion of environmental review) – Initiate procedure development as soon as possible – Design/construction by FAA with reimbursement by the Port Next Steps • Following Commission authorization… – Utilize $10M capital funds to conduct preliminary design • Projects currently identified as requiring preliminary design…

How noisy will it become in Des Moines? What are the risks to our health and the environment? How does the Sustainable Airport Master Plan (SAMP) impact crime, property values, environmental justice, and our quality of life? What health and mitigation studies are underway? What does the global science say today about these risks? What about the growth beyond 2027? The Port did not hold a planning stage meeting in Des Moines, despite requests to do so. Please attend – ask questions – and request your concerns be addressed in the environmental review! PORT OF SEATTLE – PUBLIC MEETING SEPTEMBER 10, 2018, 5:30-8:30 HIGHLINE COMMUNITY COLLEGE (Student Union Bldg 8) The SAMP is the blueprint for Airport growth through 2027. Sea-Tac has added 97,000 overflights in the last four years – that’s now 1,140 per day, 416,000 annually. The SAMP proposes (i) no limit on full-time use of the Third-Runway, (ii) another 80,000 annual “Near Term” flights, and (iii) undefined “Phase 2” growth. Scoping ends September 28th.
