Special meeting of the
Sewer Authority Mid-Coastside Directors
on Wednesday, January 4th, 2023
at 4:00pm – 6:00pm, by Zoom
Background and Discussion/Report
On December 31, 2022 an atmospheric river dropped over five inches of rain in a 24 hour period in the Coastside and throughout the Bay Area—leading to wide spread flooding, levee failures, and floodwater rescues throughout Northern California, including within San Mateo County and the City of Half Moon Bay.
The next atmospheric river, which may be even more severe than the December 31, 2022 storm, is anticipated to hit the Coastside on January 4 bringing heavy rains and high winds to soils that are already inundated—potentially resulting in catastrophic flooding. The storm events caused the following damage:
1. On December 31, 2022, the Pilarcitos Creek adjacent to the plant flooded into the Plant. Approximately, 2690 CFS was flowing in the creek at the time of flooding. The flooding into the plant caused storm water to enter the Electrical building located in Mechanical Building 1, Pipe gallery, Effluent building and caused damaged to certain equipment.
As of now, the following equipment damage has taken place:
a) Recirculation Pump 1
b) Transformer for Effluent building
c) Breakers for spray pumps to the Press
d) Chain in Primary
To protect the plant further from flooding we also had to shut off Portola Pump Station and Montara Pump Station. This caused an overflow at the Wet Weather Storage on the Burnham strip, Magellan Avenue and RV Park across Burnham strip.

SAM is a joint powers authority (JPA) created by its three member agencies: City of Half Moon Bay (City), Granada Community Services District (GCSD), and the Montara Water and Sanitary District (MWSD).
The JPA is a separate, independent, public agency created by the member agencies to perform functions and share powers common to the member agencies. Those powers are outlined in a joint exercise of powers agreement (Agreement). The Agreement creating SAM can be found on the Documents page.
Each Agreement identifies how the independent agency will be governed. In the case of SAM, each member agency appoints two members from its governing board to represent it on the SAM Board of Directors, for a total of six directors.
The Agreement also establishes the weight of each director’s vote. The vote by each representatives from the City is given the weight of two votes. The vote by each representative from GCSD and MWSD is given the weight of one vote. The total number of possible votes is eight. A quorum is a minimum of five votes and resolutions require at least six votes to pass.
