KPG provided master planning, and comprehensive project management, engineering and architectural services for the facility, which opened to public and commercial haulers February 16, 2008.  KPG services included a pro-active public involvement program consisting of voluntary public meetings, workshop, several neighborhood meetings, local Community Councils, 1% for Art, and interest groups.  The site is located within a residential neighborhood, and was once known as the Corliss Landfill.  King County and KPG facilitated significant public review and comment over a period of several years.

The transfer building is 76,000 square feet on three levels.  A covered trailer parking area is located beneath the self-haul tipping floor, thereby reducing the area of asphalt necessary in the adjacent trailer yard.

SRTS is targeted to achieve a 2008 USGBC LEED NC-2.1 ‘Gold’ Certification through the USGBC Leadership, Environmental and Energy Design (LEED) Green Building Rating System.   The project was recognized by the jury for the 2008 AIA ‘What Makes it Green’ sustainable design awards, and has been nominated for several other awards including SWANA. 

The facility's sustainable design features include:

• Enhanced natural daylighting coupled with continuously dimming high    
  performance lighting
• Passive ventilation reducing fan energy and increasing ventilation effectiveness
• Rainwater harvesting resulting in conservation of 300,000 gallons per
  year
• 15 KW solar energy photovoltaic power generation
• 83 tons reduced carbon emissions resulting from substitution of fly ash
  for cement

The project received an award from the Thornton Creek Alliance for enhancement of Thornton Creek stream habitat, removal of invasive species, and mitigation of effects of the existing landfill.
