Natural hazards

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Monte Sereno’s census tracts, against the rest of the country; all of them together, relatively moderate. It is meant for planning, not a substitute for a local risk assessment or a flood map: FEMA’s index.

From the U.S. Census Bureau’s 2020 census and its American Community Survey (2020–2024 five-year estimates), and the Bureau of Labor Statistics. A survey, so each figure has a margin of error, and figures it is not sure of are left out. More on Santa Clara County.
