Beach Interceptor Sewer Tunnel and Pipeline Repair Project

Beach Interceptor Sewer Tunnel and Pipeline Repair Project

Project plans call for stabilization of adits and portals (tunnel entry locations) to facilitate the safe entry and exit of personnel, removal of loose rock and rotten timber supports, and excavation and enlargement of the tunnel to form a stable horseshoes shape. Permanent shotcrete lining and steel supports will be installed at several locations where they may be required. Construction activities are expected to last approximately 2 to 4 years depending on the construction access method. Staging and work areas needed for access to the tunnel may be required at the following locations: - District Aliso Creek service yard - Aliso Creek Beach parking area - Pacific Coast Highway & West Street (new access shaft) - Beach end of Camel Point Drive - Adit 12 (via marine landing craft) - Thousand Steps Beach Adit 16 (via marine landing craft or existing easements) - North La Senda Drive, Manhole B (new access shaft) - Agreements with private owners for access may also be necessary.
