Am I required to carry it?
About 53.6% of the NFIP policy units in this dataset for Suffolk County are in mapped high-risk (A/V) zones — not 53.6% of all buildings. In a Special Flood Hazard Area a federally backed mortgage legally requires flood insurance.

- Zone VE1,579 policy units
- Zone C155 policy units

Zone mix by policy units (summed policyCount). Federal rule: a lender must require flood insurance on a building in a Special Flood Hazard Area with a federally backed loan (42 U.S.C. §4012a). This is the mix of existing policies, not of all buildings, and does not establish any one property's obligation.

How do current premiums compare with FEMA's full-risk price?
47.4% of 15,344 single-family policies pay less than FEMA's own full-risk price; the median full-risk premium is $2,174 versus the $1,232 actually charged.
- Median charged now$1,232
- Median full-risk price$2,174
- Pay below full risk47.4% of 15,344
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 ($1,232) would take at least about 4 annual renewals to reach the median full-risk price ($2,174). 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, Suffolk County had 33,936 paid NFIP flood claims totalling $1,097,872,558.
Orange bars are the three costliest years: 2012 ($850,292,328), 2011 ($46,651,863), 1992 ($45,437,103). 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 33,936 paid claims since 1978 against 29,237 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 1,118 properties in Suffolk County that flooded more than once and drew federal disaster aid for repeat flood losses.
- Repeat-loss properties1,118
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.

- NFIP policy units29,237
- Housing units579,790
- Policies per 100 homes5.0
A coverage-commonness proxy: policy units include some multi-unit and non-residential policies and exclude private flood insurance, so read it as how widespread NFIP coverage is here, not an exact share of households.

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.
