Can a single, large storage facility be located in Lincoln Park to accommodate peak flows from the areas served by Barton and Murray pump stations?
The project team has evaluated Lincoln Park as a potential site for storage facilities. Project engineers considered construction of a large bore tunnel in Lincoln Park for storage of combined flows between the Barton and Murray Pump Stations. This alternative was not developed due to the following challenges: • Preliminary geotechnical evaluation identified major soil stability issues along the slopes leading up to Lincoln Park. These soil stability issues would pose substantial risks during a tunneling operation. • Tunneling portals would be required at each end of the storage tunnel, impacting both Lowman Beach Park and Lincoln Park. • Costs for this option would be much higher than alternatives for CSO control sited in other locations. • This tunnel would up to 200 feet deep, increasing construction risk. • A new peak flow pump station would be required at the bottom of the Barton basin and a new force main pipeline would be required along Fauntleroy Avenue SW to convey flows to a
