​Engineering Resource Associates, Inc. conducted a GIS analysis for the mapping of overland flow paths for the Village of Lisle and surrounding tributary areas. The exhibits show overland flow routes of the natural drainage pattern of stormwater runoff during storm events and display a flow path at all locations that have at least 1-acre of area tributary.
 
The overland flow path maps will be used by the Village of Lisle to inform decisions regarding the permitting of sheds, garages, fences, pools and other structures that could block overland flow routes or be susceptible to flood damages. It also serves as a useful field reference when addressing local flooding issues and complaints by residents and other property owners outside of the flood plain.
