County Office Building 3 (COB 3) will be located on the lot across from the Hall of Justice. Once completed, the building will have multiple above-grade levels housing approximately 600 County employees. The building will be constructed to meet County green building standards including zero net energy and LEED Gold. Site demolition is complete, and design is in development. As part of the project, the portions of Hamilton and Bradford streets running through County Center will be permanently closed. COB 3 is slated for completion in 2023.
