Background Information

LA Sanitation and Environment, working in conjunction with the Bureau of Engineering, will construct the Hyperion Perimeter Road Improvement Project. The project will further stabilize the private hillside service road adjacent to the Hyperion Water Reclamation Plant. This project is very important in maintaining Hyperion’s access route around the facility for years to come. The City’s contractor is coordinating with the Los Angeles Department of Water and Power (LADWP) to access their service road adjacent to the Hyperion hillside service road.

Upcoming Activities:

The following activities are expected:

  • Deliveries and unloading of equipment/material to the Hyperion perimeter road
