pilings as high as , and a new grain elevator at South Hanford Street. U.S. entry into the war brought on further changes: effectively, the entire harbor on Elliott Bay became a U.S. military port for the duration. The Pacific Steamship Company piers south of Downtown were reworked into a Port of Embarkation (part of which now constitutes Coast Guard Station Seattle, the rest of which is part of Terminal 46). One of the longest-lasting legacies of the war years was the comprehensive May 1, 1944 renumbering of all of Seattle's Elliott Bay piers into a single system encompassing the bay. While the War years were a boom time for Seattle and its port, the immediate postwar years were not. Wartime production had made Seattle-based Boeing the region's largest employer; peace resulted in 70,000 Boeing layoffs. Nor did Seattle's port get its expected share of post-war commercial shipping traffic: for the first time ever, it was outdone even by its neighbor to the south, the far smaller city of Tacoma. While the Port of Seattle had launched what was to prove a very successful airport, wartime use of the Elliott Bay and Duwamish River waterfront had not established a particularly good basis for a peacetime port. When the military's new piers reverted to civilian use, they took business away from existing older facilities and, consequently, away from the heart of town. Further, it had been over a decade since the Port had run a major national and international publicity campaign. And there were labor troubles (see following section Politics and the Port). The Port was not entirely without a strategy. On the shore of the area around Pioneer Square and immediately south, they purchased and modernized Piers 43 and 45 through 49 from the Pacific Coast Company Piers 43, 45, 46, and 47 were eventually incorporated into present-day Terminal 46. Fishermen's Terminal at Salmon Bay was enlarged and upgraded, as was the East Waterway Dock on Harbor Island. Still, they failed to support Eastern Washington farmers with a modern grain terminal, and that trade was lost, for the time, to Portland and Tacoma. In 1949 the U.S. Department of Commerce designated a foreign-trade zone (FTZ) on Harbor Island. At the urging of the local business community, the Port invested heavily in gaining this designation and in building the facility, but it almost certainly turned out to be a money-loser over
