• To build the runway, the port purchased about 500 properties including 400 single-family homes and relocated the owners.
• There were seven construction stormwater ponds and four treatment centers during construction.
• To mitigate the impacts of filling 20 acres of wetlands, the port is creating or enhancing 178 acres near the airport or in Auburn, along the Green River.
• The third runway is not designed to increase capacity, but it will allow landings on two runways at the same time in all but the worst weather. The ports says the new runway will reduce delays and costs for passengers and airlines.

• Reconstruction of Sea-Tac’s 11,900-foot-long easternmost runway. Work to begin in the spring and finish by the fall of 2009. Budget: $85 million.
