Development accelerated with projects influenced by planners associated with movements traced to Daniel Burnham-era city planning and modernists linked to Mies van der Rohe-era architecture. Throughout the late 20th century, Oak Brook hosted events and controversies paralleling those in neighboring suburbs such as Burr Ridge, Illinois and Downers Grove, Illinois.
