Operations and Public Safety Facility

Located at Fourth Lake Forest Preserve, our Operations and Public Safety Facility in Lake Villa houses nearly 45 staff responsible for preserve maintenance, construction operations, natural resources and public safety. 

Our General Offices in Libertyville houses nearly 100 staff responsible for administration, planning, natural resources, land acquisition, public information, education and registration, as well as a public meeting room. The Lake County Discovery Museum's exhibits and staff will be moving to this location in the near future. 

Public Services

Although many everyday transactions can be handled on our website, such as picnic shelter reservations, Dog Exercise Area, equestrian and other permits—if you'd like to handle these things in person, our customer service staff will be happy to help. You'll find them here and at our General Offices.
