Cleanup Response Update
Thanks again for your patience as we continue to plan for restoration of the affected properties along the lake. We are writing to give you a status update. We reported last Friday that all clean-up activities had been completed and pipe repairs done. One of the neighbors requested an additional disinfection and pressure washing, so we went ahead and completed that on all the affected properties. The immediate public health threat has been addressed, but please wait to let your kids or dogs play in your yard until restoration is complete. For more information, view update .
