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 this county. Terrain scores are higher around La Honda, where the highest scored terrain value is 65.0, and lower near Pescadero at 5.0. Vegetation and fuels also vary sharply: the highest scored value is 80.0 in Pescadero, while the lowest is 5.0 near Pescadero. Those differences are associated with the county’s place-to-place wildfire risk variation. 20 median terrain score (max 65 near La Honda) 20 median vegetation & fuels score (max 80 near Pescadero) Fire weather ## Fire weather across _San Mateo County_ Fire weather was not measured at the sampled points in San Mateo County.

CAL FIRE has no mapped Fire Hazard Severity Zone at **42** of the 178 sampled points — the zones cover Local Responsibility Areas. The USFS grid could not read any of them either, so the hazard weight is renormalised away rather than scored as low. 178 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.
