How do current premiums compare with FEMA's full-risk price?
53.3% of 62,806 single-family policies pay less than FEMA's own full-risk price; the median full-risk premium is $1,589 versus the $1,172 actually charged.
- Median charged now$1,172
- Median full-risk price$1,589
- Pay below full risk53.3% of 62,806
Years to the full-risk price: under the statutory cap, premiums for most primary residences rise at most 18% a year (HFIAA cap, FEMA Risk Rating 2.0). At that maximum rate a policy at today's median ($1,172) would take at least about 2 annual renewals to reach the median full-risk price ($1,589). This is the cap on how fast a bill can climb, not a forecast of any one policy; statutory surcharges and fees are outside the cap.

What do floods actually pay out here?
Between 1978 and 2026, Jefferson Parish had 135,664 paid NFIP flood claims totalling $3,504,603,594.
Orange bars are the three costliest years: 2005 ($2,693,640,615), 1995 ($302,821,900), 2021 ($93,410,456). Net building + contents payments by year of loss. Claims are matched by the claims dataset's county code, which may not exactly match a policy's property county.
That is 135,664 paid claims since 1978 against 87,527 policies in force today — a cumulative tally spanning ~49 years over a present-day snapshot, not an annual claim rate or a flood probability.

How often do the same homes flood here?
FEMA has recorded 10,507 properties in Jefferson Parish that flooded more than once and drew federal disaster aid for repeat flood losses, including 1,035 rated severe repetitive-loss.
- Repeat-loss properties10,507
- Severe repetitive-loss1,035
FEMA-designated repetitive-loss (RL) and severe repetitive-loss (SRL) properties — individual homes with more than one flood loss over time, aggregated to the county and distinct from the annual NFIP claim counts above. A high count means the same homes flood again and again here. These drew FEMA Individual Assistance (for uninsured losses), so read it as a chronic-flooding signal, not an insured-claims total.

What this data cannot tell you
- Your own premium — it depends on elevation, coverage and deductible. We show where existing policies fall.
- Private (non-NFIP) flood insurance prices.
- Your address's exact flood zone — use FEMA's Flood Map Service Center.
- Why premiums are rising — we show the gap to full-risk, not the cause.
- A year-over-year premium trend — the in-force snapshot holds only current-term policies, so a like-for-like multi-year index isn't possible from this data. A per-effective-year median is shown only where several years of policies exist.
