Dahlen Township isn’t graded for hazard risk: Dahlen Township has 43 residents; we grade towns of 1,000 or more.
What Dahlen Township faces
Each hazard’s share of the building damage FEMA expects here, and how its rate compares with the rest of the country.
Hail
River and rain flooding
Ice storms
Tornadoes
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.
Does Dahlen Township flood? No paid flood claims on record
FEMA’s records show no paid flood insurance claims in Dahlen Township. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
The storms Dahlen Township remembers
None of the 29 disasters declared for Nelson County shows FEMA aid or repair money reaching Dahlen Township itself in FEMA’s records, so these are its biggest flood-claim years.
Nelson County has had 29 natural disasters declared by the President since 1953, most often floods, then severe storms. Not counted: the 2005 Hurricane Katrina evacuee emergency, which covered counties that took in evacuees.
