July 12, 2022 – Recently, a strike by International Union of Operating Engineers Local 150 against three construction materials companies – Lehigh Hanson, Lafarge Holcim and Vulcan Materials – began June 7 and has halted work at 30 quarries in northern Illinois that produce aggregate material, such as sand, gravel, and stone, impacting construction projects throughout the Chicago Area. This gravel material is critical to the Lake Ellyn Shoreline project and is contributing to the delay of the project. A permeable paver walkway will be installed after the retaining wall. The base of the walkway is the aggregate material that is hard to source at the moment due to the protest. The general contractor is making every effort to obtain materials where available to finish the project.
