Status of "Preferred Alternative" Projects - May 29, 2015

The City of Warrenville formally submitted a detailed review comment letter to DuPage County on January 17, 2012 regarding the various preliminary engineering plans prepared by DuPage County consultants. A copy of this letter can be accessed by clicking here. Links to the current plans for the various projects were provided in the section above. DuPage County also maintains a project website that can be accessed here.

DuPage County continues to work with the City of Warrenville and affected property owners (private and public) to move these projects forward. To date, the following projects have been completed:

The "Phase I" project included the construction of a levee at Bower Elementary School to protect the school property from flooding. DuPage County and the School District are currently working through the process to have the levee accredited with FEMA. Through an Intergovernmental Agreement, the School District will be responsible for the long-term ownership and maintenance of the levee.

The "Phase II" project included the excavation of significant compensatory storage in the floodplain and floodway for the projects and the construction of a flood protection berm along the east side of River Road between Bower Elementary School and Warrenville Road.  Significant improvements were made to the vegetation and habitat within the limits of this project to improve water quality in this corridor.

Currently, the "Phase III" projects are under construction. These projects include the removal and replacement of the Warrenville Road bridge and the re-meander of the West Branch DuPage River so it aligns with the bridge appropriately.  These projects will reduce depth of flooding in the area immediately north of Warrenville Road.  In conjunction with these projects, DuPage County is in the process of acquiring the commercial building on the north side of Warrenville Road and east bank of the river.  The intent is to demolish this building as the river channel will be realigned to flow through the current building location.
