What the packet contains
Sections in FEMA checklist order; each heading names the review item its tables support. Full tables are in the downloads above.
17 of the 18 National Risk Index hazards apply here.
Not applicable to this county per NRI, with no federal declaration and no Storm Events record since 1996: hurricane. That is the evidence for leaving them out of the plan.
Highest expected annual loss (NRI, modeled): Inland Flooding, Landslide and Winter Weather.
Not covered by NRI (local data needed): dam failure (incl. upstream dams); levee failure; flash flood as its own subtype; ice jams; debris flows; erosion (riverine and coastal); land subsidence and sinkholes; expansive soils.
The state hazard mitigation plan also lists hazards for this county; FEMA asks the plan to explain any hazard it leaves out.
Supports FEMA checklist item B1-b Hazard location
Avalanche, Earthquake, Landslide, Tornado, Tsunami, Volcanic Activity and Wildfire vary within the county; the packet lists the highest-rated census tracts for each.
Coastal Flooding and Inland Flooding: the FEMA Flood Insurance Rate Map (FIRM) is the required location source for flooding. See the FEMA Flood Map Service Center (https://msc.fema.gov) for this county.
Cold Wave, Drought, Hail, Heat Wave, Ice Storm, Lightning, Strong Wind and Winter Weather: affects the whole county; national data give no location within it.
Supports FEMA checklist item B1-c Hazard extent
Storm Events records for 8 of the 20 NOAA event-type groups mapped to the 18 hazards, with the scale, observed range and worst recorded event for each; the others say which local data are needed.
Worst recorded tornado, hail and thunderstorm wind (the three event types on record since the 1950s; the packet has every group):
Thunderstorm Wind: No thunderstorm wind record can stand as this county's strongest: the 1 record with a recorded speed reached this county only through an NWS zone that covers more than one county, so the wind may have occurred outside this county (zone-level); it is counted as an occurrence.
Federal declarations for this area: 4 declarations covering 2 separate hazard incidents counted in this packet; each with type, dates and county Public Assistance dollars.
New since the last plan (approved 2020-06-08): DR-4767-AK and DR-4585-AK.
4 statewide declarations listed separately.
Hazards with no Storm Events record and no federal declaration are stated as such (11 of 18).
Storm Events history: 295 records (notable ones in the PDF, all of them in the Excel file).
Supports FEMA checklist item B1-e Probability of future events
FEMA annualized frequency (modeled) for each hazard, with a descriptor from a scale defined in the packet.
Highly likely: Landslide and Lightning
Likely: Winter Weather
Possible: Avalanche, Ice Storm, Inland Flooding and Wildfire
Unlikely: Hail, Strong Wind, Tornado and Volcanic Activity
Historical frequency by intensity band (tornado, hail, wind): 9 bands from Storm Events.
Supports FEMA checklist item B1-f Hazards that vary across jurisdictions
Range of census tract risk scores within the area for 17 of the 18 hazards (1 tract; rated tracts only).
1 jurisdiction: plan clock, repeat-flood count, Public Assistance dollars and event records naming the place (starting figures from federal data).
Supports FEMA checklist items B2-a and B2-b Vulnerability and potential impacts
The packet's table gives county-level starting figures; the plan describes impacts for each jurisdiction and its own assets.
Storm Events damage since 2020-06-08: none reported in county-coded records (0 records); $0 reported for the zone (49 zone records). Data through 2026-06-30; nominal dollars.
Local data needed
To gather:
Critical facilities and lifelines per hazard
A problem statement per jurisdiction per hazard
Changes in development in hazard-prone areas since the last approval, or a statement of none (E1-a)
Population 2,120; building value $601,934,309 and agriculture value $0 (total, not at risk).
National Risk Index rating Very Low; social vulnerability Relatively High; community resilience Relatively Low.
Supports FEMA checklist item B2-c Repetitive loss properties
Repetitive-loss properties, FMA definition (44 CFR 77.2): 0 repetitive loss, 0 severe repetitive loss. NFIP insurance definition: 0 and 0.
Mitigated 0; insured 0; NFIP data as of 2026-08-02. Counts by occupancy group and for each jurisdiction are in the packet.
