The Pershing Avenue / Elm Street flow path west of Chase Street is a flow path with approximately 47 acres directly tributary. The tributary area is generally bounded by Roosevelt Road to the north, Dawes Avenue to the south, Grant Street to the east, and Naperville Road to the west.
This tributary contains an undesigned flow path through multiple private properties with four distinct upland depressional areas as well. Although some of the depressional areas are served by a small storm sewer when intense rainfalls occur, the depressional areas flood creating significant ponding near or surrounding nearby structures.
In 2016, the City of Wheaton contracted V3 Companies Inc. to complete the 2016 Flood Study Project II which included the Pershing Avenue/Elm Street Flow Path/Upland Depressional Area West of Chase Street. The purpose of this study was to determine the extent and frequency of overland flooding into the area’s homes. The area was surveyed and modeled, and an alternative analysis was completed. The final report and an inundation map can be found below.
