Document Description
The proposed Western Terminus Project is located in the Roberts Landing area in the City of San Leandro, Alameda County, California. The proposed project is the final link of the 16 mile LAVWMA Export Pipeline project as evaluated in the 1998 EIR. The LAVWMA pipeline segment known as the Western Terminus or "Gravity Pipeline 1" (GP1) connects into the EBDA pipeline in San Leandro at Roberts Landing. The Western Terminus is about 1,460 feet long and is using the original pipeline constructed in 1979. With the passage of time and normal deterioration have brought this segment towards the end of it's safe operating life under normal LAVWMA flow condition. Replacement of the original pipeline is proposed with a new 36" diameter high-density polyethelene (HDPE) pipe, installed using Horizontal Directional Drilling (HDD) techniques to bore under the recently restored Bunker Marsh which is located on the east margin of San Francisco Bay. After drilling and offsite processing of material, the new pipe would be pulled under the marsh with only minor and temporary effects to the wetland in the area.
