AGENDA
REPORT
January 18, 2022
DISCUSSION:
In 2018, the City of Richmond (“City”) entered into a second settlement agreement with San Francisco Baykeeper (“Baykeeper”) because the City was unable to meet the terms of the 2016 City-Baykeeper Settlement Agreement involving significant sanitary sewer overflows during wet, rainy weather because of the City’s sanitary-sewer collection system’s conditions. Under the second settlement agreement in 2018, the City agreed to improve its sewer collection system. Additionally, Baykeeper requested performance of a feasibility study to determine the condition of the Keller Beach Sewer Trunk line given its sensitive location along the Point Richmond shoreline.
Thereafter, the City commissioned Express Sewer to clean the Keller Beach Sewer Line and inspect the line via CCTV. To perform a complete assessment of the sewer line, the City contracted with NCE and Coastland who evaluated CCTV data submitted by Express Sewer and created a report of findings (“Report”). That Report is attached for Council’s approval (Attachment 2).
The City requests that Council approve the resolution to accept the Report so the City can proceed with a complete study regarding the two (2) options suggested in the study, which are:
1. Repair of the Existing Sewer Main with Cast In Place Pipe (CIPP) The drawbacks of the CIPP liner option are that the repair:
• Does not provide full new construction design life to the sewer main facilities;
• Does not correct sags, and the pipe profile will continue to adjust and degrade;
• Does not address the poor maintenance access; and,
• Does not address the high-risk and cost of sanitary sewer overflows into the Bay in the event of a pipe break.
2. Replacement of the Keller Beach Sewer in a New Location The drawbacks of the sanitary sewer main relocation options are that it:
• Is an extremely costly project;
• Would take years to implement; and,
• Would need numerous homeowners’ participation(s).
Both options are very costly and would take a significant time to implement. However, given the current, compromised condition of the Keller Beach sewer line, the City will be forced to decide sooner rather than later.
This Report serves as the qualitative basis for the Point Richmond Sewer Emergency Moratorium, which is a separate action being presented to the Council.
