The Washington Avenue Drainage Improvements project is a priority project identified during the Lake Yale Basin Study (currently in progress). This project addresses flooding and water quality concerns within the Lake Yale Basin. Refer to the Lake Yale Basin Study web page for more information.
The project is located in the vicinity of Washington Avenue and its adjacent streets in the Eustis Park Subdivision on the east side of Lake Yale. The project area encompasses a contributing area of approximately 25.5 acres. A detailed site map is linked below.
There is minimal stormwater conveyance features within the project area. Existing conveyance features which are present include culverts and swales, many of which are in poor condition. The lack of conveyance and storage for runoff has resulted in localized flooding. The intent of the project is to improve the stormwater conveyance for the project area by regrading swales and installing ditch bottom inlets and storm sewer pipes to more effectively convey runoff to the outfall point.
Additionally, this area currently has no specific water quality treatment in place to address stormwater pollutant loadings. Water quality is of particular concern since there is a Total Maximum Daily Load (TMDL) for phosphorus for Lake Yale. Based on this, this project will consider locations for stormwater ponds (for flood prevention and water quality) and/or water quality treatment structures as best management practices.
This project is being conducted by the Lake County Public Works Department. The engineering study efforts are being performed by Inwood Consulting Engineers, Inc. A project schedule is linked below.
Construction of the Oak Street outfall is complete. Phase II design is currently underway for the interior roads. Construction of the Phase II improvements is tentatively scheduled for 2013.
