Gas Works Park

SITE DESCRIPTION

Gas Works Park is on the north shore of Lake Union, approximately 5 miles north of downtown Seattle. The park juts into Lake Union, while the north end of the park is bounded by Northlake Way. From the early 1900s until 1956, gas companies operated a plant at the site that converted coal and oil into manufactured gas. The American Tar Company operated nearby, manufacturing tar from coal by-products. Leaks and wastes from the gas works and tar production facilities contaminated the soil and groundwater as well as sediments in Lake Union.
