Development & Diversification

Overview
The Port recorded its first million-ton cargo year in 1970, with logs totaling 98% of the volume. Marine Terminal berths were again deepened to keep pace with the trend toward larger, deep-draft ships. However, strong growth at the Marine Terminal was offset by retrenchment at the airport, when the 30-year air passenger service was suspended.

In the midst of these changes, the Port dedicated some of its growing East Bay waterfront property to a recreational boat marina, the first such non-industrial Port facility for the residents of Thurston County. Completed in the early 1980s, East Bay Marina, now called Swantown Marina, was initially leased to a private operator. The marina has been managed by the Port since 1987.

Construction
Further diversification efforts led to the construction of a 76,000-square-foot, clear-span warehouse at the Marine Terminal in the mid-1980s. Port facilities at the Olympia Regional Airport and the NewMarket Industrial Campus (formerly Thurston Airdustrial Center) were also improved and linked more closely to the Interstate 5 corridor with the construction of the Airdustrial interchange in 1986.
