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. Additional attention will have to be paid when modeling this area as a depressional watershed exists in Glen Ellyn that may contribute to this flow path during large rain events.
This depression is in the rear yards of properties along Lorraine Road and likely overflows onto Lorraine Road in a yet to be determined rain event.
