C+Hazard risk
Natural hazards in Ronan · FEMA

FEMA expects about as much hazard damage per building in Ronan as in the typical U.S. town, mostly from earthquakes

On FEMA’s National Risk Index, Ronan gets a C+ for hazard risk: higher expected damage per building than 56% of U.S. towns. Most of that expected damage is earthquakes (52%), then river and rain flooding (37%). FEMA’s files show no paid flood insurance claims here.

Coastal floodingHurricanesTsunamisVolcanic activity
People, not buildings.Counting harm to people as well as buildings, FEMA’s model puts avalanches at 35% of Ronan’s expected losses. Avalanches do little damage to buildings (0.0%), so they aren’t part of the grade.

Shares are of FEMA’s expected building damage, the measure the grade uses; ranks compare each hazard’s building-damage rate with all 85,154 U.S. census tracts. In FEMA’s terms, river and rain flooding is FEMA’s “Inland Flooding” (rivers and streams overflowing their banks, or rain overwhelming drainage). FEMA defines coastal flooding as high or rising tides and storm surge, so surge damage is counted there. Drought isn’t listed: FEMA counts its losses in crops only.

Flood risk changes street by street. Check a specific address on FEMA’s flood map, and ask about flood insurance before you buy.

Shared tract.All of Ronan’s 1,955 residents (2020 census) live in one census tract, which it shares with Kicking Horse CDP (76 residents). FEMA publishes its model by tract, so the rate and the hazard mix are the tract’s, the same for all of them. The flood claims below are the town’s own.

Flood insurance claims

Does Ronan flood? No paid flood claims on record

FEMA’s records show no paid flood insurance claims in Ronan. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.

Insurance rates: Lake County.
Disasters

The storms Ronan remembers

Disasters declared, by decade
Paid out in RonanLake County only

Lake County has had 4 natural disasters declared by the President since 1953, most often severe storms, then floods. Not counted: the 2005 Hurricane Katrina evacuee emergency, which covered counties that took in evacuees.

Also 1 FEMA wildfire suppression grant (Fire Management Assistance, not a disaster declaration) for fires in Lake County, 2000–2000.
