City of Oconomowoc, WI
The City of Oconomowoc reconstruction of 2,500 lineal feet of Allen Road, from Johnathon Drive to Concord Road. Wetlands and several culverts directing runoff to the Oconomowoc River are adjacent to the project site. Oconomowoc is in the Rock River TMDL area, and is actively taking efforts to reduce the amount of Total Suspended Solids (TSS) and Phosphorus that reach surface waters via the municipal storm sewer system.
Ruekert & Mielke, Inc. (R/M) incorporated a grasslined
swale behind the curb and gutter system to allow for treatment and infiltration of the runoff prior to reaching the wetlands and conveyance systems leading to the Oconomowoc River. The result is a traditional urban section roadway with curb cuts and a grass swale system that work in conjunction with each other to reduce runoff peak flows and volumes, and provide water quality treatment.
