Gas Works park is on the site of an old gasification plant that once powered much of Seattle from 1907 to the mid 1950's. It was said that nothing would ever grow on this ground again due to the hydrocarbon contaminates, soot and petro chemical waste polluting the soil.
Parks, Power - Gas
A massive soil cleaning effort was needed to create the park that now stands in it's place. Portions of the original "Gas Works" remain, the largest remnant of the 1,400 such plants that existed in the US, and can be seen in the background.
