Background , formed in 1918 on
Commencement Bay in Tacoma In 1911, the
Washington State Legislature authorized the creation of port districts through public referendums. The ports of Seattle and Tacoma were formed separately in 1911 and 1918, respectively, to establish public control of municipal waterfronts. The two ports, located apart, facilitated exports of the state's natural resources and imports from
Asia, which intensified during
World War I at the end of the decade. During
World War II, the ports were used for military
shipyards and other wartime uses, reverting to civilian trade afterwards. The rise of cargo
containerization in the 1960s helped offset declining traffic to the Port of Seattle, leading to an $80 million modernization and expansion program begun in 1968. The Port of Tacoma debuted its own cargo container-ready facilities in 1970, and gradually lured away several large shipping lines from Seattle through the 1990s, including Alaska-based
Totem Ocean Trailer Express (1976),
SeaLand (1983),
Maersk (1985),
K Line (1988), and
Evergreen Marine (1991). The Port of Seattle's largest line,
Hyundai Merchant Marine, moved to a new, $65 million terminal in Tacoma in 1996. By the turn of the 21st century, Tacoma eclipsed Seattle to become the largest port in the state and 7th largest in the nation, but fell behind ports in
Los Angeles and nearby
Vancouver. In 2009, Seattle regained its title as the larger of the ports, but both suffered losses in overall cargo volume and revenue. Tacoma lost Maersk to Seattle after Maersk signed a vessel sharing agreement with
CMA CGM in 2009, but three years later attracted an alliance of three major international shippers from Seattle who had comprised 20 percent of cargo for the port. The Port of Tacoma called a merger unnecessary and costly to their city, citing lower costs to expand in Tacoma and scaring off possible operators with higher fees; the Port of Seattle stated they were uninterested in a merger unless they could guarantee an equal partnership with Tacoma. The two ports met in the late 1990s to discuss collaboration or a potential merger, amid the consolidating of shipping lines (favoring centralized
distribution centers in fewer ports) and the merging of the state's railroad system into
BNSF Railway. In 2012, Port of Seattle staff estimated that rate competition with Tacoma had reduced cargo revenue by $35 million annually (approximately $70,000 per acre), based on comparisons with the
Port of Oakland, which has no competing port in the region. Both factors led to the Washington State Legislature proposing a merger of the ports of Seattle, Tacoma and
Everett in 2008, which stalled after the Port of Tacoma opposed. In 2014, the market share of ports in
British Columbia tripled and overtook the combined traffic of Seattle and Tacoma for the first time. The port commissions began talks of a merger in early 2014, including an agreement to share rates and other information under federal oversight and an "unusual" joint announcement for the transfer of a local shipping line to Tacoma.
Formation of alliance On October 7, 2014, the ports of Seattle and Tacoma formally announced their intention to move management of their marine cargo businesses to a joint alliance in March, ending decades of competition, because of increased threats from British Columbia and other ports. A full merger, including the two port commissions, was opposed by Tacoma, who feared that the more populous
King County would have more votes on the combined commission than
Pierce County, who were more dependent on the cargo port. In March 2015, the plan was pushed back to August while working on specifics of the alliance, including a decision on which
legal entity it would fall under. The Washington State Legislature and Governor
Jay Inslee approved the creation of a port development authority, similar to Washington's existing
public development authority designation, in late April. On June 5, 2015, the two port commissions voted unanimously to merge their marine cargo operations into the alliance, christened "The Northwest Seaport Alliance", pending approval from the
Federal Maritime Commission (FMC). The FMC approved the planned alliance on July 23, 2015. On August 4, 2015, at the
Federal Way city hall, the two port commissions unanimously approved a formal agreement creating The Northwest Seaport Alliance. Under the agreement, properties from both ports would be placed in a common pool and the operations would be overseen by both elected port commissions. Port of Tacoma CEO John Wolfe was selected to be the alliance's first
chief executive while remaining with Tacoma. The combined port authority became the
third largest cargo port in the United States and by container volume.
Early years On February 29, 2016, the Northwest Seaport Alliance invited the
CMA CGM Benjamin Franklin, the largest cargo ship to visit the United States, to dock at the Port of Seattle's Terminal 18. The move was used to test the terminal's capabilities in handling a ship of that size (in the range of 18,000
twenty-foot equivalent units, or TEUs) and promote expansion of Terminal 5 into a facility to handle larger ships. In April 2016, the alliance approved $141 million in funding to upgrade piers and cranes at the Port of Tacoma's Husky Terminal. The alliance celebrated its first anniversary in August 2016 with a new joint operations center and continued growth in traffic, despite a drop in shipping caused by slower growth in Asia. Later that month,
Hanjin Shipping, a major operator in Seattle, filed for bankruptcy and was barred from the Port of Seattle over fears of unpaid terminal fees. The bankruptcy sent the global shipping industry into a panic, with several Hanjin ships anchored off the Pacific coast awaiting approval to unload cargo. In December, Hanjin's Terminal 46 in Seattle was sold to an affiliate of
Mediterranean Shipping Company for $78 million; the move was opposed by the Port of Seattle, who filed a request to block the sale over a lack of correspondence about the new lease and security deposit. ==Governance==
