SAN RAFAEL CITY COUNCIL AGENDA REPORT
Department: Public Works
Prepared by: Bill Guerin,
Director of Public Works
City Manager Approval: __________
TOPIC: SAN QUENTIN PUMP STATION
SUBJECT: INFORMATIONAL REPORT REGARDING THE SAN QUENTIN PUMP
STATION RECONSTRUCTION PROJECT AND FUNDING
RECOMMENDATION:
Accept the informational report.
BACKGROUND:
The San Quentin Pump Station was constructed in 1972 and is located in the saltwater marsh wetland and detention pond behind Target and Home Depot off Shoreline Parkway. The pump station conveys stormwater from the detention pond into the San Rafael Bay through a 960-foot outfall pipe that goes underneath the levee along the San Francisco Bay Trail. The existing pump station building is approximately 720 square feet in size and consists of a wet well, pressure vault, associated controls, and two vertical pumps.
After almost 50 years of operation, both the pump station and outfall pipe are beyond their useful life and need to be replaced. Without a functioning pump station at this location, stormwater would overflow from the detention pond into the neighboring industrial areas and inundate Interstate 580. Additionally, climate change is anticipated to result in larger storm events and rising sea levels therefore requiring an improved, more powerful pump station in place of the existing one. The new pump station will have additional pumping capacity and will also be more energy efficient than the existing facility. Staff is also studying the feasibility of an in-line trash capture device that will filter any debris running through the system. Staff is seeking State funding for the trash capture device with the intention of installing it soon after the pump station is completed.
On December 18, 2017, the City Council approved an agreement with CSW/Stuber-Stroeh Engineering Group, Inc. for preliminary engineering services resulting in a Basis of Design/Feasibility Study. After amending the agreement on October 1, 2018, the design consultant commenced environmental studies and construction drawings. As required by CEQA, on January 21, 2020, Council adopted the Mitigated Negative Declaration for this project and directed staff to proceed with final design and pursue regulatory environmental permits.
SAN RAFAEL CITY COUNCIL AGENDA REPORT / Page: 2
That effort is nearing completion we expect to obtain the necessary permits to construct this project this spring.
ANALYSIS:
Construction of the San Quentin Pump Station is estimated to cost $3.2 million. Additional costs related to construction including contingency, construction management, and inspection costs will also be needed. The average annual Stormwater Fee funds available for CIP projects is only $500,000. Therefore, City staff has been actively pursuing grant funding to support the construction effort. In December 2019, staff applied to the FEMA Hazard Mitigation Grant Program to obtain $2.4 million of federal funds, but that grant application was unsuccessful. In August 2020, staff also applied to the State’s Urban Flood Protection Grant Program to obtain $1.5 million and that grant application was also unsuccessful. At this point, staff does not have a funding alternative for this important climate change-related infrastructure project that would be superior to using the American Rescue Plan Act (ARPA) funding.
In 2021, the City received funding through ARPA that can be used for CIP projects, and ARPA specifically calls out water infrastructure projects as eligible. City staff recommends that ARPA funds be used for the construction of this project. This project directly or indirectly touches on all of the City Council’s key focus areas for 2021/22, with a particular concentration on the key focus area of “Sustainability, Climate Change, and Disasters.” It is also a very significant infrastructure project that has been planned for many years without an available alternative funding source.
In addition to presenting the funding plan, this item is being brought forward to the City Council as an informational report at this time to raise awareness of a very significant infrastructure project, in the millions of dollars, prior to it coming to the City Council for formal bid award.
FISCAL IMPACT:
There is no fiscal impact for the acceptance of this informational report. City staff will proceed to advertise and award the construction project and will recommend appropriation of the ARPA funds at a future Council meeting once a construction contractor is identified.
OPTIONS:
The City Council has the following options to consider relating to this matter:
1. Accept the informational report as presented.
2. Do not accept the informational report
3. Direct staff to return with more information.
RECOMMENDED ACTION:
Accept the report.
