Beach Interceptor Sewer Tunnel and Pipeline Repair Project
EIR - Draft EIR
The South Coast Water District operates the "Beach Interceptor Sewer and Tunnel" located between Three Arch Bay and Aliso Creek Beach in the southern area of the City of Laguna Beach, Orange County, California. The approximately 6-foot wide by 6-foot high tunnel was constructed in 1954 and is approximately two miles long, extending from South La Senda Drive in Three Arch Bay north to Aliso Creek Beach. The tunnel is mostly unlined and unsupported; however, heavy timber struts and wooden lining (lagging) have been installed in several sections of the tunnel. Over the past 56 years, subsequent repairs have been made to the wooden lagging, and a relatively short segment of the tunnel was enlarged and fortified with shortcrete in 2007. The tunnel condition is deteriorating with age, and repairs are needed throughout the tunnel to prevent tunnel and sewer pipe failure and allow safe working conditions in the tunnel.
