Sanitary Sewer Parallel Trunk Line (Manhole T-0 to T-32)

Sanitary Sewer Parallel Trunk Line (Manhole T-0 to T-32)

The East Palo Alto Sanitary District (lead agency) is proposing to construct a new, 18-inch sanitary sewer line, parallel to an existing 24- to 30-inch sanitary sewer line, from manhole T-0 within the Palo Alto Regional Water Quality Control Plant, running north/northwest through the Palo Alto Airport (airport) site to manhole T-32, just east of San Francisquito Creek bridge. The total length is approximately 6,000 linear feet. The proposed improvements are located outside of the district service boundaries and within the City of Palo Alto. The new sanitary sewer line route would begin at manhole T-0 and proceed across Embarcadero Road north through the airport outdoor airplane parking area to manhole T-4 where the route turns northwest and parallels the runway along the east side of the adjacent golf course. At manhole T-10, the route turns southwest and runs between the golf course and the San Francisquito Creek Trail. The route ends at manhole T-32. Construction activities will include survey staking of the pipeline alignment, trench excavations, import and placement of pipes, manholes, and backfill materials, compaction of backfill, and restoration of ground surface to match existing conditions. The width and depth of construction would be 20 feet, and 10 feet, respectively. Delivery of construction materials, a staging area, and traffic patterns on airport property will be coordinated with the Airport. The district will also work with Federal Aviation Administration (FAA) and the airport to determine and implement the steps required to obtain a utility easement through the airport. A construction schedule for the proposed project is not known at this time but could last up to 12 months.
