ZIP 01905
Essex County, MA

The heaviest year

2018 is the heaviest year on file: 72 paid claims, 38.5% of the ZIP's total. That one year accounts for more than a quarter of the ZIP's entire record. The largest named event in the record is March 2010 Nor'easter, with 6 claims.

113 of those claims — 60.4% — were filed since 2017. This is not a historical record — most of it is recent.

Where the claims sat on the map

Of the 174 claims here that record a rated flood zone, 44 — 25.3% — were on properties rated outside the mapped high-risk area, in a B, C or X zone. Being outside the high-risk zone has not meant much here. Flood insurance is not required outside the high-risk zone, and most properties there do not carry it — so these counts come from the minority who did.

The water near this ZIP

The closest gauges publishing official flood thresholds are Ipswich River at South Middleton (7.9 mi), Boston Harbor at Boston (IN MLLW) (8.5 mi) and Muddy River at Brookline (11.2 mi). A gauge describes one point on one river — it will not see street drainage, sewer backup, storm surge or flash flooding.

What this does not say

These are paid National Flood Insurance Program claims, nothing more. They count insured properties whose owners filed and were paid, so they are a floor on how often this ZIP has flooded — never a measure of how likely it is to flood next. Uninsured flooding leaves no trace here at all.

The figures are aggregates published by FEMA. No individual claim, address or policyholder appears on this page or in the data behind it. Nothing here is a forecast, a warning, or advice about insurance.
