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.
