Infrastructure & hazardsNew England
Storms keep washing out New England’s roads, and 1 in 5 high‑hazard dams is rated poor or worse
Since 2011, $1.3B of permanent repairs after declared disasters in New England have run through FEMA’s Public Assistance program — 53% of it roads and bridges. Where that money went, the condition of 1,030 high-hazard dams, and what the landslide inventory can and can’t tell you.

What disasters cost the ground
After a federally declared disaster, FEMA’s Public Assistance program pays towns and state agencies to clear debris and rebuild what broke. Across 96 declarations since 2011, the single largest line is the one closest to the ground: washed-out roads, culverts and bridges.
Jul 2023 flooding (VT) and Tropical Storm Irene (VT) top the repair bill
FEMA Public Assistance dollars per disaster declaration, split by type of work. The 12 costliest since 2011.

The years the storms came
Each bar counts state declarations — a storm that hits three states is three. Most are rain and flood events; the latest on file is DR-4919-MA (severe winter storm and snowstorm, Jun 30, 2026).
2011 brought the most federal declarations (24); 2005 and 2024 had 20 each
Major-disaster and emergency declarations in the six states, by year declared and type of event, 2005–2026.
- Severe storm & flood
- Hurricane & tropical
- Winter, snow & ice
- Other
“Other” is mostly 2020’s COVID-19 emergencies and 2005’s declarations for sheltering Hurricane Katrina evacuees.

03 · Dams
The typical high-hazard dam here was finished in 1914
New England has 1,030 dams whose failure would probably cost lives. The typical one was finished in 1914; 343 of the 926 with a known date predate 1900. Most are earth embankments (641).
What “high hazard” means. It describes the consequence if a dam failed (probable loss of life downstream), not the chance it will. Condition is the regulator’s latest assessment reported to the National Inventory of Dams, and states inspect and rate differently — compare states with care. We show no inundation or emergency-plan information.

The landslide map is a map of who went looking
The USGS inventory holds 3,513 mapped landslides in New England, and 87% of them are in Vermont. That is not because Vermont slides and Connecticut doesn’t: the Vermont and Maine geological surveys mapped landslides systematically and supplied 3,454 of the points; the other four states add only a few dozen.
Mapped inventory, not a hazard map. A blank area means nobody has mapped it, not that the ground is stable. 3,092 of the 3,513 records (88%) are low-confidence interpretations, and 2,660 carry a placeholder date of 1970 — so the inventory can’t show whether landslides are becoming more common.
Vermont’s surveys account for 87% of mapped landslides

Where these numbers come from
Method, sources & caveats
FEMA figures come straight from OpenFEMA’s public API, pulled in full (every page, no row cap) for the six New England states each time this page’s data is refreshed: 23,925 Public Assistance projects for disasters declared 2011–2024, and 197 declarations since 2005. Dollars are project amounts — federal plus state and local share — as last obligated; the federal share was $1.8B of the $2.4B total.
Dams are every “High” hazard-potential dam in the National Inventory of Dams (USACE), read from the full national extract. Landslides are the USGS inventory’s points for the six states as captured on Jun 24, 2026, binned into hexagons in the pipeline so no single record is plotted.
- FEMA dollars are Public Assistance project amounts (eligible project cost, federal + non-federal share) for disasters declared 2011–2024, from OpenFEMA's funded-projects file. Withdrawn and ineligible projects are dropped; state management costs (category Z) are excluded from the damage totals.
- COVID-19 declarations (incident type "Biological", $7.2B in New England) are excluded: they paid for emergency measures, not ground or infrastructure damage.
- Project amounts are not inflation-adjusted and reflect the latest obligation, so recent disasters can still grow as projects are written. Disasters declared in the last months may have no project records yet (currently DR-4919-MA).
- Declarations count each state's declaration once (a storm hitting three states is three declarations). County designations count distinct major-disaster (DR) declarations naming the county.
- Dams: every dam classified High hazard potential in the National Inventory of Dams for CT, ME, MA, NH, RI and VT (1,030 dams). "High hazard" describes the consequence if a dam failed (probable loss of life), not the likelihood it will. Condition is the state or federal regulator's latest assessment as reported to NID; 76 high-hazard dams have no rating.
- Per NID terms we publish no Emergency Action Plan or inundation information, round dam coordinates to 0.01° (about 1 km), omit owner names, and do not rank dams by danger.
- Landslides: 3,513 points from the USGS U.S. Landslide Inventory compilation (pulled 2026-06-24). It maps where geologists have looked — the Vermont and Maine geological surveys mapped landslides systematically — not where slopes are most likely to fail. 2,660 records carry a placeholder date of 1970 and 3,092 are low-confidence.
- Counties with no FEMA project records are blank on the map; statewide projects are counted in state totals but not assigned to a county. FEMA records the applicant's county, so a state agency's repairs can be filed under the capital's county rather than the damaged site.
