Port of Seattle and Seattle-Tacoma International Airport

The Port of Seattle is a special-purpose municipal corporation established by King County voters in 1911. Its jurisdiction is coextensive with King County, Washington, and five commissioners elected countywide govern the agency. The Port owns and operates Seattle-Tacoma International Airport and manages maritime facilities, including cruise terminals, fishing and recreational moorage, and industrial properties. Its work includes transportation infrastructure, commercial property operations and regional economic development. An executive director oversees daily administration under authority delegated by the commission. The Port’s headquarters is at Pier 69 on Seattle’s waterfront; the airport is in the separate city of SeaTac.
