PHASED APPROACHPlanning Status Update

7

• Airfield/airspace constraints result in major congestion (aircraft delays) as activity nears 59 million passengers (2029)

• Phased approach required to advance SAMP – Identify projects to accommodate near-term demand within existing

constraints – Near-Term projects– Conduct environmental review of Near-Term projects

– Follow-on planning study to address airfield/airspace constraints

• Near-Term projects– Near-Term projects can accommodate 2027 market demand– Approximately 56 million annual passengers

Phased approach required to meet future demand

Phased approach required to meet future demand

• Airfield/airspace constraints result in major congestion beyond 2027

• Phased approach required to advance SAMP–Identify projects to accommodate near-term demand within existing constraints –Near-Term projects–Conduct environmental review of Near-Term projects–Follow-on planning study to address airfield/airspace constraints–Resolve constraints in the future phase

• Near-Term projects–Near-Term projects can accommodate 2027 market demand–Approximately 56 million annual passengers and 480,000 annual operations
