Harbor Board hears water‑quality restoration plan for San Francisco Bay beaches; staff warn many sources are outside district control

The harbor district received a staff briefing on an "advanced restoration plan" adopted last week by the regional water quality control board to address fecal indicator bacteria at San Francisco Bay beaches that abut San Mateo County. The plan—intended as a less administratively heavy alternative to a formal total maximum daily load (TMDL)—identifies actions for local marinas and waterfront facilities, and asks participating jurisdictions to step up education, monitoring and infrastructure measures.

General Manager said the plan requests marinas boost "no dumping" education, continue free pump‑out and mobile pump‑out services, provide dump stations, step up controls on trash compactors and continue routine water‑quality monitoring. "If we're able to control the bacterial load and get down to acceptable levels, a TMDL may not be necessary," the general manager said, summarizing the water board's approach.

Why it matters: commissioners and staff stressed the plan's implementation depends on cooperation among multiple agencies. Board members noted that while the plan targets beaches in the bay (including the Oyster Point area inside the marina), many of the likely bacteria sources—stormwater runoff, failing sanitary infrastructure, and upstream urban drains—originate outside the district's jurisdiction.

Board members pressed staff on source identification and monitoring. Commissioners were told the county or regional agency conducts weekly bacterial testing and identifies fecal indicator bacteria associated with human and animal waste; staff said testing shows higher counts near storm‑drain outfalls and after rain events. The general manager and commissioners repeatedly emphasized that "the storm water really is not caused by us" and that the district will need to coordinate with the city of South San Francisco and other regional partners to address runoff and sanitary system issues.

District responsibilities under the plan are largely operational and educational: the district already provides pump‑out and dump stations, collects trash multiple times daily at harbor facilities, and holds certifications for stormwater permit compliance and a clean harbor certification. Staff said they will continue regular reporting to the regional board as required by the plan and will work with county partners on monitoring results.

Commissioners suggested additional regional engagement, including encouraging greater monitoring resources, working with developers and the city to control stormwater, and exploring whether lost grant opportunities (one commissioner noted an $800,000 grant previously lost due to a delayed water‑board response) can be revisited. Staff indicated the district would bring updates and next steps to future meetings and work through existing stormwater permit and regional coordination channels.

What the plan does not do: it does not apply to Pacific coast beaches and it does not immediately impose new enforcement powers on the district. Rather, it frames actions that, taken with other jurisdictions, could prevent escalation to a formal TMDL. The board received the report; no board action was required at the meeting.

Next steps: staff will continue to coordinate with the county and city environmental partners on monitoring, submit required reports to the water board, and bring follow‑up items to the board, including recommended outreach and any proposed technical or funding requests to assist regional monitoring efforts.
