Managing the toxic soil involved several strategies: removing the most toxic soil, capping and collecting the mildly contaminated soil, and then reusing it as part of the landscape.

Part of the design included the creation of wetlands around the former parking lot. The wetlands help manage excess stormwater, store excess carbon, and provide habitats for multiple species of plants and animals. Almost immediately after construction, meadows appeared and cattails sprouted along the water.

The original landscape was shaped by ice-age glaciers. The mounds along the paths mimic the original sculpting of the land while storing remediated soil.
