Parcel Risk Report
Flood risk in and around Ferndale, Humboldt County
FEMA's official flood map draws the 1%-annual-chance floodplain. FEMA's National Risk Index adds a comparative flood-risk rating for every census tract — a broader, neighborhood-scale measure. Here's how the tracts in and around Ferndale rate, and how to check one address.
1 of 1
census tracts in and around Ferndale are rated Relatively High or Very High for riverine or coastal flood risk by FEMA's National Risk Index.
| Census tracts intersecting Ferndale | 1 |
| … rated Relatively High or Very High for flood (riverine or coastal) | 1 |
That puts parts of the Ferndale area among the higher-rated neighborhoods in FEMA's national flood-risk comparison. The National Risk Index rating is a comparative, composite measure (it reflects expected losses and community vulnerability, not just the mapped floodplain), so it complements the official FEMA flood map rather than contradicting it — check a specific address to see the map's call for one property. These are tract-level ratings (neighborhood scale), not parcel-precise and not a count of homes.
Flood-rating breakdown for Ferndale
| Riverine flood — Very High | 1 |
FEMA rates riverine and coastal flood separately, so one tract can appear in two rows — these rows can therefore add up to more than the 1 elevated tract above (a tract is "elevated" if either rating is Relatively High or Very High). Categorical classes from FEMA's National Risk Index — never a proprietary score.

How this figure is derived (and what it is not)
- Counts come from FEMA's National Risk Index census-tract layer, limited to the tracts that intersect the U.S. Census Bureau 2020 boundary of Ferndale (Humboldt County, state-county FIPS 06023).
- A tract is counted when its riverine or coastal flood rating is "Relatively High" or "Very High" — FEMA's own comparative categorical classes, never a proprietary score, never a per-parcel prediction.
- We say "in and around Ferndale" on purpose: census tracts don't line up with city limits, so a tract is included if it touches the boundary — and for a small city, many counted tracts may extend well beyond its limits. Read the figure as the surrounding neighborhood, not the city alone. It is a tract count, not a homes count, and not parcel-precise.
- Ratings: FEMA National Risk Index (https://hazards.fema.gov/nri/). City boundary: U.S. Census 2020 incorporated places (census.gov). Both update rarely; data retrieved 2026-06-02.
- This is general public-data information — not a Natural Hazard Disclosure Statement, and it does not satisfy California Civil Code §1103.2 (the seller's statutory disclosure in a sale).
