Bolingbrook FAQ
My neighbor regraded and now water pools on my lawn — what can I do?
File a complaint with Will County Land Use (unincorporated) or your municipal engineering department. Illinois follows the reasonable use rule, and redirecting concentrated flow onto your lot creates liability for damages.
Do I need a permit to fill a low spot in my backyard?
If the fill is under 400 cubic yards and does not alter drainage onto neighbors or into a floodplain, no county permit is needed in unincorporated areas. Municipal thresholds are lower — check locally.
