In 1906, on a peninsula on the northern shore of
Lake Union, the Seattle Gas Company constructed a
coal gas plant. By 1956, this plant was shut down and left behind old refinery towers. Upon the City of Seattle's purchase of the land in 1970, Haag was the lone person who was asked to develop a park design for the site. While most planners had expected the demolition of the refinery towers, Haag decided to keep them. However, he did not incorporate them into the design for historic purposes, but rather to visually enhance the design of the park. While convincing city government to accept this radical plan was challenging, Haag's development of a design which integrated
bioremediation methods in order to detoxify the soil without transporting and replacing it amplified the issue. Haag and his colleagues suggested using oil-degrading enzymes and organic material to stimulate growth of microorganisms and breakdown toxic materials that were still present in the soil left behind by the ancient industrial processes of the plant. Before Richard Haag was asked to develop this design, he submitted the site as a design problem to a national undergraduate design competition. All 130 designs submitted removed any indication that a gas plant ever existed in that site. Through this, Haag took the environmentalist ideal to another level and acknowledged the potential aesthetics of industrial structures without causing harm to the environment. His design for Gas Works Park brought Haag his first
American Society of Landscape Architects (ASLA) President's Award for Design Excellence. ==Bloedel Reserve==
