Springfield sits in central Illinois along the Sangamon River. Lake Springfield, the city's reservoir, creates recreational waterfront real estate with moderate flood risk. Spring Creek and Town Branch run through older neighborhoods. Significant portions of east Springfield lie in the Sangamon River 100-year floodplain. The city has a mix of well-maintained state government buildings and aging residential housing with deferred maintenance plumbing. Illinois clay soils (gleysols) cause chronic basement seepage and hydrostatic pressure issues throughout the region.
Flood-prone areas: East Springfield and areas near Sangamon River are highest flood risk. Westchester and Chatham (southwest suburb) are newer with better drainage. Capitol complex area has government-maintained infrastructure.
