The following flood services are available to Lisle residents, free of charge:

  • Floodplain Determination Letters can be requested for any property within the village

Drainage System Maintenance
The Village inspects the public drainage system, which includes storm sewers, roadside drainage ditches, bridges, and culverts on Lisle creeks and the East Branch of the DuPage River. Because of the critical role these systems play in preventing flooding, it is extremely important that they function correctly.
 
Village ordinances strictly forbid dumping or discharging anything other than stormwater into the drainage system. Illegal dumping or discharge is punishable by fines issued through Code Enforcement. Violations should be reported to Village Hall via telephone or email.

Additional Information
To report any illegal dumping or discharges into a storm drain, creek, or the river, please call the Village of Lisle Code Enforcement at 630-271-4150 or complete the new online service request form.
