Northerly Island Chicago, Illinois, United States
Converting a private airport into a haven for wildlife. In 1909, Daniel Burnham envisioned Northerly Island as a lakefront haven for the public on the shores of Lake Michigan in downtown Chicago. The 37-hectare peninsula was constructed in 1920 but spent 57 years of its history as a concrete desert until 2003 when its stint as a private airport ended. The island had no aquatic connection to Lake Michigan and consisted mostly of turf grass, resulting in no habitat diversity and little overall ecological value. So in 2012, the U.S. Army Corps of Engineers (USACE)–Chicago District proposed transforming 16 hectares of the island into re-creations of the six habitats native to the Chicago region: lacustrine, dunal pond–lacustuary lagoon, emergent marsh, wet prairie, mesic prairie, and savanna. They moved 160,000 cubic meters of material, excavating a pond and connecting it to Lake Michigan, building up savannas, and planting a range of native vegetation—275,000 plugs, 11,800 shrubs, 400 trees, and 150 kilograms of seed. USACE completed construction in 2020; and now Northerly Island is a thriving, natural oasis for people and wildlife alike, all amid the Chicago skyline.
