The Old Chisholm Trail Stormwater Improvements project is a priority project identified during the Lake Yale Basin Study. This project addressed flooding and water quality concerns within the Lake Yale Basin. Refer to the Lake Yale Basin Study web page for more information.
The project area is in the vicinity of Old Chisholm Trail in the Yale Retreat subdivision on the southeast side of Lake Yale. The project area encompasses a contributing area of approximately 140 acres, including upstream areas of agricultural land and residential areas near State Road 19. The project area outfalls to Lake Yale through a culvert beneath Old Chisholm Trail. A detailed site map is linked below.
The culvert that drains under Old Chisholm Trail was clogged and in disrepair which caused flooding associated with the upstream ditch system. The focus of this project was to replace this culvert to provide improved drainage in the area. Additionally, this area does not have any specific water quality treatment in place to address stormwater pollutant loadings. This is of particular concern since there is a Total Maximum Daily Load (TMDL) for phosphorus for Lake Yale. Based on this, this project also seeked to identify opportunities for water quality improvement through the implementation of best management practices (BMPs).
This project was conducted by the Lake County Department of Public Works. The engineering study efforts were performed by Inwood Consulting Engineers, Inc.
This project was completed in July 2008.
