Long-term vision 
Unconstrained forecast of 66 million annual passengers by 2034

Long-term vision  planning update 
Airside modeling 
Conducted initial round of modeling 
Recalibrated model to 2016 conditions 
Modeled long-term future improvements 
Findings 
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 
Recommend follow-on planning study to address airfield/airspace constraints 
Phased approach required to meet future demand meet demand

Long-term vision - phased approach 
Near-term projects - 56 million annual passengers by 2027 
Long-term vision  Additional planning required for demand beyond 2027

Limitations of Translatable Documents

PDF files are created with text and images are placed at an exact position on a page of a fixed size.
Web pages are fluid in nature, and the exact positioning of PDF text creates presentation problems.
PDFs that are full page graphics, or scanned pages are generally unable to be made accessible, In these cases, viewing whatever plain text could be extracted is the only alternative.
