Project details

Starting on June 3, 2024, EBMUD crews will begin installing a new water pipeline to enhance water service in your Lafayette neighborhood. Please refer to the detour map below to see how St Mary’s Road will be affected. Side streets intersecting with St Mary’s Road will also experience temporary impacts as work progresses. The project is expected to continue until October 2024, and the duration of construction on each street may vary. Final paving will follow the completion of construction. For details on the affected work area, please review the accompanying detour map.


Work hours are 7 a.m. to 4:30 p.m., Monday through Friday. EBMUD will provide traffic control. Residents may experience delays of up to 10 minutes when entering and leaving the work area. If you have special needs, please call us and we will make every effort to accommodate.
