The Glendale Avenue Overland Flow Path has a direct tributary of approximately 58 acres. The tributary area stretches out of Wheaton and into Glen Ellyn and is generally bounded by railroad tracks to the north and west, Sawyer Avenue to the south, and Vine Street to the east.
This tributary area, in general, has aggressive topography with steep slopes and the City has very few reported overland flooding incidents until the flow path crosses onto the west side of Glendale Avenue.
In 2018, the City of Wheaton contracted Engineering Resource Associates to complete the 2018 Flood Study Project VI which included the Glendale Avenue Overland Flow Path Flood Prone Area. 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.
