Ramona Street Impacts
We are working with the City of Bellflower and Bellflower Somerset Mutual Water Company to reduce service interruptions to trash, water, and traffic.
Water service shutoffs will be for only one single 12 -hour shutoff for each property and no critical facilities will be allowed to be shutoff.
No on-street parking will be in phases along Ramona Street.
We are working with the City of Bellflower and the trash hauler service provider on a modified trash pickup schedule during each phase.
We have coordinated with the City of Bellflower a full closure of Ramona St. & Bellflower Blvd. and Ramona St. & Clark Ave during weekends from Friday 5pm to Monday 6am to not impact commuter traffic.
Ramona Street Impacts
Typical service interruption
•7 am: Bypass and testing.
