•  SEA has 2.5 million square feet of
Pavement Condition Index (PCI)                                                                             Landside pavement
•  Maintain a minimum pavement
condition at the lowest total cost
of ownership
•  Goal is to maintain pavements at
PCI rating of 70 or more

             Project Purpose and Scope
The Landside Pavement Program will rehabilitate SEA landside pavements
in order to maximize the useful life of assets and ensure operations
•  Pavement rehabilitation will include pavement overlay or replacement
– Removal of abandoned utilities within work areas
– improvements to related surface water drainage facilities
– Comply with required codes or standards (e.g., signage, lighting, sidewalks,
bicycle lanes)
•  Locations include the South Parking Entrance, Northern Airport
Expressway, Air Cargo Rd, S 190th St, Starling Dr, and S 160th St

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.
