The 2020 Stormwater Master Plan identifies and prioritizes capital improvement projects that are designed to aid in residential stormwater drainage. It includes a ten-year capital plan which identifies drainage conditions throughout the Village and mitigation steps to improve conditions. This plan was developed with valuable input from Lisle residents, committee members, Village staff and elected officials, along with expert analysis and recommendations provided by professional consultants.
The Village contracted Engineering Resource Associates, Inc. (ERA) to prepare a village wide Stormwater Master Plan to serve as a roadmap for determining future hydrologic and hydraulic analysis needs, design needs and construction projects. Lisle's location on a river and its tributaries has resulted in a long history of flooding. Storm sewers, swales, drainage ditches and detention/ retention ponds also play an important part in the Village's overall stormwater management system.
