"Relatively Moderate" is the middle rung of FEMA's five-tier scale: Very Low, Relatively Low, Relatively Moderate, Relatively High, Very High. It means your location's risk, measured as expected annual loss, sits in the middle of the national range, higher than most low-risk areas and lower than the high-risk ones. The word "relatively" is the key: every rating is a ranking against the rest of the country, not a probability that a disaster will strike. You may also see Not Applicable and No Rating, which are different from a low score and are explained below.
Your report grades the overall risk and each individual hazard on the same scale. Once you know what the tiers mean, the whole grid becomes readable in about a minute. Here is the full decoder.
FEMA sorts every location into one of five tiers based on where its score falls relative to all others nationally. The color coding on your report runs green to red across these tiers so the high ones stand out.
| Tier | What it means | How to read it |
|---|---|---|
| Very Low | Among the lowest-risk locations nationally | Little expected loss from this hazard here |
| Relatively Low | Below the national midpoint | Present but modest relative to most areas |
| Relatively Moderate | Around the middle of the national range | Worth noting; not extreme in either direction |
| Relatively High | Above the national midpoint | A hazard to price and plan around |
| Very High | Among the highest-risk locations nationally | A leading driver of risk here; check coverage |
Because the tiers are relative, "Very High" does not mean a disaster is imminent, and "Very Low" does not mean impossible. It means this location ranks near the top or bottom of the country for expected loss from that hazard. To understand why the index is built on loss rather than raw odds, see what expected annual loss means.
Some cells in your grid will not carry a tier at all. These are not the same as a low rating, and mixing them up is the most common misreading:
The honest takeaway: a blank is not a green light. It is either "does not apply" or "we cannot say," and only the per-hazard tiers are actual risk statements.
Your report leads with the overall rating and its national percentile, then shows the individual hazards, with the highest-rated ones pulled to the top. A practical way to read it:
One sentence to remember: the tiers rank your location against the whole country for expected loss, the elevated ones tell you where to act, and a blank (Not Applicable or No Rating) is never the same as Very Low. Read the parts, not just the headline.

Ratings reflect FEMA's National Risk Index, an expected-annual-loss index at the census-tract level, not an official determination for your individual lot. Reviewed 1 July 2026.
