The Ferry Creek Watershed is approximately 12.2 square miles in size and includes portions of the Cities of Warrenville and Naperville, and unincorporated areas of Winfield and Naperville Townships. The Country Lakes and Longwood Subdivisions located in unincorporated DuPage County suffered extensive flooding during a July 1996 storm event. A watershed study was performed to determine the location and extent of overbank flooding and analyze alternatives to reduce or eliminate this flooding. The Country Lakes Storm Sewer System Drainage Improvement Project was one improvement that was recommended in the Ferry Creek Watershed Plan that was approved by the DuPage County Board in July of 1999. The project included the installation of approximately 5,700 feet of storm sewer in the Country Lakes and Longwood Subdivisions in unincorporated DuPage County, as well as the construction of more than 6.5 million gallons of compensatory stormwater storage on property located at LaSalle Avenue and Bond Street.
