# Wildfire risk in Santa Clara County: _where it is highest_, and why

Wildfire risk is not uniform across Santa Clara County. In the places we scored, the middle value is 54.8, with lows around 13.4 in Los Gatos and highs up to 82.5 near San Jose. That spread means two homes in different parts of the county can face very different wildfire exposure.

## Half of Santa Clara County scores _High_ or worse

We scored 167 points across Santa Clara County on the same 0–100 scale a Satelife address report uses, and they do not land in one place. 10% of them come out Very High, while 27% are Low. Which end your own parcel sits at is not something a county map can tell you.

Communities

## Where in the county you are _matters most_

Among larger cities, lower wildfire risk scores appear in places like Sunnyvale (13.4) and San Jose (16.7), while Santa Clara is higher at 23.4.

Higher community values show up in Morgan Hill (55.4), Gilroy (48.4), and Saratoga (66.9). That pattern matches the county’s wider spread between urban lowlands and more exposed edges.

At smaller-community scale, Redwood Estates is 58.9 and San Martin is 52.4, while Los Altos Hills is 13.4. Nearby places can still differ a lot.

The score is the median of the sampled points nearest that community — a community-scale indicator, not a score for any individual property in it. Population comes from the community's own record where the source carries one.

Terrain & fuels

## Terrain, vegetation and _fuels_

Fire weather was not measured at all in Santa Clara County in the places we scored.

Vegetation and fuels also vary sharply by place. Scores run from 5.0 in Milpitas to 80.0 near Morgan Hill, with a middle value of 65.0.

Fire weather was not measured at the sampled points in Santa Clara County. The other four indicators on this page were, and the bars below show what they found.

What drives it

## Which part of the risk _moves_, and which doesn't

Wildfire risk varies a lot by location in this county. The lowest scored point is 13.4 in Los Gatos, while the highest is 82.5 near San Jose.

By tier counts, High is the most common level among the places we scored, with 83 points. Low is next, with 45 points.

Moderate includes 22 points, and Very High includes 17 points. So higher-exposure tiers are common, but they are not the whole county.

Each bar is what one part of the score covers across Santa Clara County, on the same 0–100 scale. A long bar is a part of the risk that depends on where you are; a short one is the same almost everywhere.

Independently of Satelife's layers, the USFS Wildfire Risk to Communities grid puts the county's mean annual burn probability at **1.14%** (90th percentile cell: **2.53%**), with a mean conditional flame length of **3.69 ft**. **85%** of the 23,330 grid cells inside the county carry burnable fuel at all.

Source: USFS Wildfire Risk to Communities v2.0 (ImageServer, county extent).

CAL FIRE has no mapped Fire Hazard Severity Zone at **2** of the 167 sampled points — the zones cover Local Responsibility Areas. At **1** of them the USFS grid above supplied the hazard reading instead; at the remaining 1 the hazard weight is renormalised away rather than scored as low.

167 sample points on a ~2.3 km grid, plus one at the centre of each community, weighted with the Satelife county profile v1 · median layer coverage 90%. Scores are 0–100 and comparable within the county, not across states.

For a property

## What a county range means for _one address_

For property context, hazard-zone scores are wide in this county: 10.0 in Gilroy up to 90.0 near Gilroy, with a middle value of 70.0. This layer contributes to why parcels in different locations can have very different wildfire risk.

Fire-history scores also span a wide range, from 5.0 in Gilroy to 95.0 in Santa Clara, with a middle value of 20.0. Past fire footprint is one of several factors associated with current exposure.

A separate federal model reports a mean annual burn probability of 1.14% and a 90th-percentile cell value of 2.53%. It also indicates that 84.6% of the county can burn.

Across 167 sampled points in Santa Clara County, the score runs from 13.4 to 82.5 — two neighbouring parcels can sit in different tiers. A county number is the middle of that spread; it says nothing about which end yours is at.

Did this county include fire-weather scoring?

No. Fire weather was not measured at all in Santa Clara County in the places we scored.

How should I read the FEMA ratings on this page?

They are county-wide ratings from FEMA’s National Risk Index. For wildfire, FEMA rates Santa Clara County as Relatively Moderate for risk and Relatively High for expected annual loss.

This page is generated from a Santa Clara County data pack assembled on 2026-08-18 (pack v1.0). Scores are sampled across the county, not measured at any individual address, and are informational decision support — not a substitute for official evacuation orders, a fire-agency hazard determination, or an insurer's underwriting judgement. Data versions: fema\_nri 1.20.0 (Dec 2025) · landfire per adapter · nifc\_history All Years View · wfigs current · wrc v2.0 (2024) · zcta Census 2020.

## What does _your parcel_ look like, layer by layer?

A county range shows the spread. An address-level Satelife report shows where in that spread your property actually sits — PDF, per-layer score, and a prioritized mitigation plan.
