Constructed in 2004 by COWHEY GUDMUNDSON LEDER, LTD., this earth dam stands at a height of 7.8 feet and spans a length of 750 feet. With a storage capacity of 114 acre-feet and a drainage area of 1.32 square miles, this dam plays a crucial role in managing water flow and mitigating potential flooding events along the EAST TRIB EAST BR AUX SABLE CR watershed.
The dam features an uncontrolled spillway type with a width of 197 feet, allowing for the release of excess water during high flow conditions. While the hazard potential is classified as low, the risk assessment indicates a moderate level of risk (3). The dam is inspected every five years, with the last inspection conducted in July 2019. Despite the absence of a condition assessment, the Grande Park Subdivision Detention As-7 Dam remains a key infrastructure for flood control in Kendall County, Illinois, ensuring the safety and protection of residents in the region.
As a privately owned structure regulated by the Illinois Department of Natural Resources (IDNR), the Grande Park Subdivision Detention As-7 Dam exemplifies the collaboration between private entities and state agencies in managing water resources and enhancing climate resilience. With its strategic location and design features, this dam not only reduces flood risks but also contributes to the overall water management efforts in the area. As climate change continues to impact water systems, structures like the Grande Park Subdivision Detention As-7 Dam play a crucial role in safeguarding communities and promoting sustainable water resource practices in Illinois.
