Risk-assessment baseline packet. County FIPS 02158. Release 2026-10, data as of 2026-09-30.
Summary
Plan status as of 2026-09-30: No county-level plan row in FEMA data.
Highest expected annual loss (FEMA National Risk Index, modeled total; see B1-a): Cold Wave ($10,653,731 a year), Winter Weather ($149,972) and Earthquake ($23,629).
The packet's tables are organized by the items of FEMA's Local Mitigation Plan Review Tool, Element B (B1-a to B2-c); the summaries below follow the same order.
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.
Supports FEMA checklist item B1-a Hazard identification
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): Cold Wave, Winter Weather and Earthquake.
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 9 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):
- Hail: No hail record can stand as this county's largest: the 1 record with a recorded size reached this county only through an NWS zone that covers more than one county, so the hail may have occurred outside this county (zone-level); it is counted as an occurrence.
- Thunderstorm Wind: No thunderstorm wind record can stand as this county's strongest: the 3 records 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); they are counted as occurrences.
- Tornado: No tornado record can stand as this county's worst: the 2 records reached this county only through an NWS zone that covers more than one county, so the tornado may have occurred outside this county (zone-level); they are counted as occurrences.
Supports FEMA checklist item B1-d Previous occurrences
Federal declarations for this area: 11 declarations covering 9 separate hazard incidents counted in this packet; each with type, dates and county Public Assistance dollars.
No county-level plan row in FEMA data, so there is no approval date to count from.
4 statewide declarations listed separately.
Hazards with no Storm Events record and no federal declaration are stated as such (9 of 18).
Storm Events history: 484 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: Lightning and Winter Weather
- Likely: Coastal Flooding, Cold Wave, Ice Storm and Inland Flooding
- Possible: Avalanche and Landslide
- 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).
12 jurisdictions: 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.
No county-level plan row in FEMA data, so there is no approval date to count from.
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)
- Future assets
Supports FEMA checklist item B2-a Vulnerability (county context)
Population 8,356; building value $968,728,466 and agriculture value $0 (total, not at risk).
National Risk Index rating Relatively Low; social vulnerability Very High; community resilience Very 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.
