Aurora straddles Kane and DuPage counties west of Chicago along the Fox River. The Fox River is a significant flood corridor — periodic flooding affects lower-elevation river-adjacent properties. Aurora is part of the Chicago metro area's clay soil belt, creating the same foundation seepage and basement infiltration issues common throughout northeast Illinois. The city has significant older industrial and residential stock alongside newer master-planned developments. Winter brings classic Great Lakes lake-effect weather — freeze events and heavy snow loads stress plumbing and roofing systems.
Flood-prone areas: Downtown Aurora and Fox River adjacent areas have highest flood risk. Sugar Grove and North Aurora suburbs are newer with better drainage. Naperville-adjacent east Aurora has premium residential stock.
