Bolingbrook FAQ
Does my home addition need a stormwater permit?
Additions creating less than 5,000 sq ft of new impervious surface and disturbing less than half an acre are exempt from the WCSMO permit, though they still count toward municipal lot-coverage limits. Projects in FEMA floodplains trigger additional review regardless of size.
How do I know if my property is in a floodplain?
Check the FEMA Map Service Center at msc.fema.gov using your address, or use the Will County GIS floodplain viewer. Properties along the Des Plaines, DuPage, Hickory Creek, or Kankakee Rivers frequently lie in the 100-year floodplain and require elevation certificates for construction.
