Washington Street West watershed - City of Champaign

Draft ReportWest Washington Street Watershed Master Planthis area and very few homes would be eliminated at this site. The pond would belocated between West Washington Street and Harriet Street, along North James Street.There are multiple pond discharge opportunities from the local sewers or the NorthEdwin Street trunk sewer, but the pond would need to discharge directly into the NorthEdwin Street trunk sewer.This pond is still located close enough to the worst flooding area to provide direct reliefto the high water level, but is far enough away to not quite provide enough of an impact.There would only need to be four homes removed for the footprint of this pond andwould provide both surface flow and storm sewer hydraulic relief. The location wouldalso be expandable or could be part of a multiple pond watershed management design.Even though the home removal is kept to a minimum, there would still be homesremoved and if the pond footprint were expanded even more homes would be eliminated.There would be more storm sewer required and a relatively small pond size for this pondlocation than for many of the other pond alternatives. The effectiveness of this pondlocation as a standalone or a multiple pond design is also questionable.Church Street PondFigure 6-9Church Street PondSeptember 20096-14Clark Dietz, Inc.
