ISSUE
Board authorization is required for the General Manager to execute a revision to an agreement in an
amount greater than $100,000.
BACKGROUND
The Central Contra Costa Sanitary District (Central San) operates a 3.5-mile, 72-inch reinforced concrete
outfall pipeline (outfall). The outfall, constructed in 1958, runs primarily underground for nearly 19,000 feet
and has a submarine section that is about 1,700 feet long. Above the shoreline portion of the outfall, an
unvegetated, tidal mudflat extends approximately 1,000 feet from the shore and into Suisun Bay. Central
San's National Pollutant Discharge Elimination System permit requires proper maintenance of the outfall
pipeline. Every five to ten years, Central San conducts routine outfall maintenance work that requires
dewatering of the outfall for inspections and repairs before returning it to service. Central San also
maintains a variety of infrastructure associated with the outfall, including maintenance structures, access
risers, air relief valves, cathodic protection systems, inclinometers, and leveling monuments. The outfall
lies within areas of sensitive habitat for special status species, which would require approval from resource
agencies to execute construction.
In 2020, the Outfall Improvements, Phase 7, District Project (DP) 7353, completed a full internal
inspection and survey of the pipeline as well as necessary repairs and improvements. In 2022, the Outfall

Monitoring Improvements, DP 100018 replaced or constructed new inclinometers and leveling
monuments and completed additional minor maintenance work that was not completed in 2020.
Each round of maintenance work requires coordination with various resource agencies to obtain necessary
approval and/or permits, as well as required reporting and inspections. The agencies include, but are not
limited to, the San Francisco Bay Regional Water Quality Control Board, United States Army Corps of
Engineers, United States Fish and Wildlife Service, and California Department of Fish and Wildlife.
Central San and its biological consultant started to prepare for the applicable permit applications more than
a year prior to the commencement of the 2020 and 2022 outfall improvements. Preparation work included
biological surveys for sensitive species and habitat, jurisdictional delineations, drafting permit applications,
and evaluating potential project impacts and related mitigation on protective species and habitat. Following
permit application submittals, further coordination was required with the permitting agencies to conduct site
visits as well as to finalize the permit conditions, payments, and follow-up submittals. There were over 120
permit requirements Central San were subject to before, during, and after construction.
Due to the extensive efforts involved in obtaining permit applications, Central San is considering longer -
term programmatic permits, or routine maintenance agreements, that would cover multiple routine
maintenance projects that Central San would complete at different time periods during the term of the
agreement. These programmatic permits would describe and regulate the potential routine required work
and its biological impacts, as well as potentially save both Central San and permitting agencies' resources
by eliminating the need to permit each routine maintenance project on the outfall.
This agreement extension with Zentner Planning and Ecology (Zentner) would cover remaining regulatory
requirements from the 2022 outfall work. In addition, it would include biological resource assessments,
evaluating potential impacts and mitigation, coordination with various state and federal agencies,
completing the required permit applications, and as -needed biological consulting services.
A formal Request for Proposal was issued by the Capital Projects Division to select Zentner for the
original work. The selection followed an internal evaluation panel comparing 11 different proposals.
ALTERNATIVES/CONSIDERATIONS
Central San staff could continue the process of filing new permit applications with all required resource
agencies well before each round of outfall maintenance work. Staff does not recommend this moving
forward as the process is time consuming and may negatively impact construction due to lengthy
permitting processes. Also, permit conditions for the 2022 outfall work stipulate various requirements
through 2023. Central San will not be able to address those requirements before the current contract
expires.
FINANCIAL IMPACTS
The existing Agreement No. 32060 with Zentner has a cost ceiling of $152,000. The amendment would
add $116,000 to the existing agreement and extend the duration to July of 2026. This amendment would
bring the agreement cost ceiling total to $268,000. This amendment will be capitalized under the
Treatment Plant Planning, DP 7363.
