Montara Water & Sanitary District Statement on Superior Court Ruling
re: City of Half Moon Bay v. Sewer Authority Mid-Coastside,
Montara Water and Sanitary District, and Granada Community Services DistrictMontara, CA – On Tuesday, August 12, Judge Julia L. Alloggiamento of the Superior Court of Santa Clara County ruled in favor of Granada Community Services District (GCSD) and Montara Water and Sanitary District (MWSD) over the City of Half Moon Bay’s 2017 litigation related to the Sewer Authority Mid-Coastside (SAM) contract. Today’s ruling affirms that the City of Half Moon Bay must fund work related to the SAM Intertie Pipeline System (IPS), an integral part of our Coastside’s sewage system. Half Moon Bay has spent almost eight years attempting to renege on the SAM contract and shift its financial obligations onto its northern neighbors.
Today’s oral ruling follows a December 2023 decision by the Sixth District Court of Appeal in San Jose to return the lawsuit to the trial court. This Appeals Decision followed a February 2022 Santa Clara County Superior Court ruling which ended the City of Half Moon Bay’s (HMB) lawsuit.
The 2023 Appeals Decision did not rule in HMB’s favor, it merely identified legal and factual grounds for returning the lawsuit to a trial court. Specifically, the Court asked the trial court to resolve whether work planned in 2017 on the SAM IPS constitutes “maintenance” under the General Budget provision of the SAM Joint Powers Agreement, or “construction” under the Project Budget provision.
“Though MWSD is pleased with today’s ruling, we are saddened by the significant expense that has been imposed upon our Coastside residents by the City of Half Moon Bay’s choice to file litigation,” said MWSD Board President Scott Boyd. ‘Ultimately, the legal fees expended by MWSD, GCSD, and HMB are truly the whole Coastside’s loss. Whether you live in HMB, Granada or Montara, these funds have not been invested in our infrastructure, we do not have improved or new assets in the ground after all this expense.”
MWSD and GCSD have stood firm throughout these last eight years – all JPA parties must pay their fair share to operate and maintain the system. Regardless of today’s ruling, the Districts remain poised to move forward on critical repairs needed to protect our coastline.
SAM was formed in 1976 under a Joint Exercise of Powers Authority (JPA) contract between GCSD, HMB, and MWSD, and is tasked with protecting public health and our beautiful coastal environment.
In 1976, in order to serve all three communities, the partners of SAM chose to construct, own, and operate wastewater infrastructure, including the Intertie Pipeline System (IPS) and a single consolidated treatment plant. The IPS conveys wastewater from Montara and Granada (including a portion of the City of Half Moon Bay inside Granada’s boundary) to SAM’s Treatment Plant in Half Moon Bay. During heavy rain events, when increased wastewater flows can overwhelm the treatment plant, the IPS provides essential storage capacity to prevent releases of untreated sewage into the ocean.
For more than 45 years, SAM has operated and maintained constantly aging infrastructure. Throughout the years, we have seen the benefit of three agencies working together to share staffing, maintenance, and repair costs.
In 2017, the City of Half Moon Bay abruptly sued in an attempt get out of paying its share of the millions needed to maintain and repair the IPS, disregarding 45 years of financial partnership and the clear contractual language of the JPA. This action would have doubled costs for Granada, Princeton, and Montara/Moss Beach.

Press Release from Granada Community Services District (GCSD). on August 12th, 2025.
The Granada Community Services District (GCSD) is pleased to report that Judge Julia Alloggiamento of the Santa Clara Superior Court today ruled in favor of GCSD and the Montara Water and Sanitary District (MWSD) in response to the City of Half Moon Bay’s 2017 lawsuit regarding funding issues for the Sewer Authority Mid-Coastside Joint Powers Authority (SAM). The decision affirms that the City must continue to pay its fair share toward work on the SAM Intertie Pipeline System (IPS), a vital part of SAM’s and the coastside’s sewage network. The judge ultimately ruled that the SAM JPA agreement entered into by all three agencies in 1979 provided for a consolidated coastside wastewater treatment and conveyance system, with costs shared by all member agencies based on their respective flows into the system.
The SAM IPS transports wastewater from Montara and Granada (and the northern portion of the City) to the SAM Treatment Plant located in Half Moon Bay. For more than 45 years, SAM’s three member agencies shared costs for staffing, maintenance, and repairs of the IPS and treatment plant. In 2017, Half Moon Bay sued to avoid its responsibility for millions of dollars in IPS pipeline maintenance, disregarding decades of cooperation as well as the basic tenents of the JPA.
While GCSD is understandably pleased with the Court’s decision, it laments the costs of the lawsuit on its ratepayers, and all three agency’s ratepayers. GCSD continues to look forward to working together with SAM, the City, and MWSD to provide cost effective wastewater treatment services on the coastside.
Press Release from City of Half Moon Bay Statement Following SAM Trial; City Considers Rate Increases and Special District Formation
On August 12, 2025, Judge Julia Alloggiamento of the Santa Clara Superior Court ruled for Granada Community Services District and Montara Water and Sanitary District in the parties’ longstanding dispute over who is responsible for paying the over $25 million cost to replace the intertie pipeline, which transports wastewater from Granada and Montara to SAM’s treatment plant.
While we have great respect for the court, the City of Half Moon Bay is disappointed in the judge’s ruling. The City is now considering how best to proceed, including whether to appeal to the Court of Appeal in San Jose.
City Manager Matthew Chidester explained “As the judge acknowledged in today’s ruling, the decision will unfortunately have a disproportionate burden on Half Moon Bay ratepayers. Assuming it stands, the City will need to move forward with rate increases to pay for 62 percent of the cost to replace the intertie pipeline. We believe the ruling will also disincentivize Montara and El Granada from making cost-efficient infrastructure decisions if they know Half Moon Bay ratepayers will pick up 62 percent of the tab. ”
Chidester continued, “We think the JPA model needs either to be radically revised to reflect current regulations and Proposition 218 cost-benefit nexus rules or be replaced with a special district that consolidates the three agencies. Multiple grand juries have recommended consolidation under a special district. The upside of a special district is that Coastside residents would pay the same rates, the district could take advantage of financing of major infrastructure projects to come, offer lifeline rates to seniors and low-income residents, and govern through district elections.”
Since 2017, Half Moon Bay has been seeking a court judgment declaring the obligations of the three members of the Sewer Authority Mid-Coastside (SAM) Joint Powers Authority (Half Moon Bay, Granada Community Services District and Montara Water and Sanitary District).
The purpose of these efforts has been to protect Half Moon Bay ratepayers from paying unwarranted costs to replace the intertie—a system of pipes and pump stations that carry wastewater from Granada and Montara to SAM’s treatment plant in Half Moon Bay – a pipeline system which does not serve Half Moon Bay ratepayers.
In December 2023, the Court of Appeal ruled for Half Moon Bay and reversed an earlier trial court’s ruling for the two Districts. That ruling sent the case back to the trial court – (the Superior Court of Santa Clara County) for a trial before a judge sitting without a jury.
The trial began on Friday, July 25 before Judge Julia Alloggiamento, and it concluded on August 12.
This ruling concludes the $25-million replacement of the intertie is “operations and maintenance” for which the City must bear 62% of the cost, and not construction or reconstruction to be funded only by the Districts. This means City ratepayers are responsible for 62 percent of the costs of replacing the intertie. The City will need to increase sewer rates to fund intertie expenses, along with other capital projects to improve and maintain the City’s sewer collection system.
As has always been the case, the City of Half Moon Bay is committed to working in good faith with SAM and the other two SAM agencies, for the mutual benefit and protection of all three agencies’ ratepayers and the environment we share.

10/2023. California 6th Circuit Court of Appeals Summary Judgement: reversed Judge Rudy’s decision – “We conclude the agreement is ambiguous and capable of multiple reasonable interpretations regarding what constitutes “maintenance” or a “project,” and that the extrinsic evidence is conflicting, thereby creating a triable issue of material fact precluding summary judgment. Accordingly, we reverse and remand with directions to enter a new order denying all parties’ motions for summary judgment.”

SAM Directors
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.
