Flood risk in and around Eastvale, Riverside 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 Eastvale rate, and how to check one address.

16 of 16

census tracts in and around Eastvale are rated Relatively High or Very High for riverine or coastal flood risk by FEMA's National Risk Index.

Census tracts intersecting Eastvale	16
… rated Relatively High or Very High for flood (riverine or coastal)	16

That puts parts of the Eastvale 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 Eastvale

Riverine flood — Very High	14
Riverine flood — Relatively High	2

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 16 elevated tracts 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 Eastvale (Riverside County, state-county FIPS 06065).
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 Eastvale" 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).
