Monte Sereno is an independent Santa Clara County city at the base of the Santa Cruz Mountains between Los Gatos and Saratoga. Santa Clara LAFCo’s 2015 review records incorporation in May 1957 and identifies residential use as the predominant land use. The wooded foothill setting belongs to a distinct municipality rather than a neighborhood of neighboring Los Gatos. The service review describes council-manager government with partner agencies and contracts providing several municipal services. Law enforcement and dispatch were provided through the Los Gatos-Monte Sereno Police Department, and animal-control services through the Silicon Valley Animal Control Authority. These are dated examples of shared provision, not evidence that Monte Sereno lacks its own municipal identity. Library and recreation arrangements also crossed city boundaries in the review. It described county-library service, including a bookmobile stop at Daves Elementary School, and recreation through the Los Gatos-Saratoga Recreation District. The report’s statement that the city had no park or library building of its own describes 2015 conditions, not a live facility inventory. West Valley Sanitation District appears in the report’s wastewater and stormwater discussion, with wastewater treatment linked to the San Jose-Santa Clara Regional Wastewater Facility. This local network explains why an infrastructure concern may involve more than City Hall. Use current municipal and provider records for operational questions, while keeping the review’s service agreements and condition assessments explicitly historical.
