In 1997, the U.S. Army Corps Engineers designed and constructed a one-mile-long levee, which is maintained by the Lake County Department of Public Works, to protect against flooding that plagued the North Libertyville Estates subdivision for years.
The levee construction as currently built would have contained all major flooding that has occurred in Lake County since the subdivision was built in 1954. Recent data, however, has shown that Lake County has been experiencing more frequent and stronger rainfall events. Due to the increased frequency and intensity of rainfall events countywide, there is an increased chance that the levee will overflow within the next 25 years.
In 2020, Lake County began a study to analyze drainage improvements next to the levee and to look at further floodproofing the levee support system due to the increased rainfall Lake County is receiving. The study determined that further floodproofing of the levee is not a feasible option. However, Lake County Public Works is moving forward in 2022 with some drainage improvements to help alleviate ponding on the backyard side of the levee.
