Stormwater management engineering services were performed by TWM to successfully complete this project. Initially, we completed a comprehensive stormwater study to determine the source of flooding at the intersection of IL Route 160 and Old Hwy 50, which was causing hazardous driving and flooded homes during significant rain events. TWM’s effective yet economical solution included a 1,117’ – 36” RCP trunk line to bypass the existing 18” CMP storm sewer, 300’ of smaller diameter pipes, 842’ of open drainage, and 163’ of curb and gutter. Keeping the design within existing ROW eliminated the need for additional private easements. TWM also provided surveying, construction layout and construction observation.
