摘要

This paper describes the history leading up to the project, the construction methods, significant events and the principal elements of the system. The project setting, community involvement and environmental aspects are a large consideration for this project located in the heart of the Hollywood Hills under the famous Hollywood sign. The work is taking place in an environmentally sensitive area adjacent to the Upper and Lower Hollywood Reservoirs, which supply the drinking water for 500,000 people. The Department has placed a high emphasis on community involvement to facilitate construction, including building of a dedicated access road to minimize the construction traffic through the neighborhood. The project consists of two world-class size 30 million gallon storage tanks, a 10-foot diameter 6,000 foot long bypass tunnel, a 6-foot diameter 1,200 foot long utility tunnel, underground connection to the existing Weid tunnel and associated piping and mechanical facilities.
