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 Banning rate, and how to check one address.
| Census tracts intersecting Banning | 9 |
| … rated Relatively High or Very High for flood (riverine or coastal) | 4 |
That puts parts of the Banning 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.
| Riverine flood — Very High | 3 |
| Riverine flood — Relatively 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 4 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.
City figures are a starting point. To see what the official FEMA flood map will say for one property in Banning — side by side with these cited federal & state sources — run the free per-address check:
