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

14 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: avalanche, coastal flooding, tsunami and volcanic activity. That is the evidence for leaving them out of the plan.

Highest expected annual loss (NRI, modeled): Cold Wave, Inland Flooding and Tornado.

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

  • 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.
  • Earthquake, Hurricane, Landslide, Tornado and Wildfire vary within the county; the packet lists the highest-rated census tracts for each.
  • 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.

Supports FEMA checklist item B1-c Hazard extent

Storm Events records for 12 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: 3 in hail, 2023-06-16
  • Thunderstorm Wind: 78 kt (90 mph) estimated gust, Thunderstorm Wind, 2010-11-29
  • Tornado: EF5 tornado, 2011-04-27, 6.05 mi within this county, 1,320 yd wide, $2,500,000 property; $0 crops (2011 dollars), 16 direct deaths, 37 direct injuries

Supports FEMA checklist item B1-d Previous occurrences

Federal declarations for this area: 26 declarations covering 22 separate hazard incidents counted in this packet; each with type, dates and county Public Assistance dollars.

New since the last plan (approved 2025-04-10): DR-4899-MS and EM-3640-MS.

3 statewide declarations listed separately.

Hazards with no Storm Events record and no federal declaration are stated as such (7 of 18).

Storm Events history: 640 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: Hail, Lightning and Strong Wind
  • Likely: Cold Wave, Drought, Heat Wave, Inland Flooding, Landslide, Tornado and Winter Weather
  • Possible: Hurricane and Ice Storm
  • Unlikely: Earthquake and Wildfire

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 14 of the 18 hazards (11 tracts; rated tracts only).

7 jurisdictions: plan clock, repeat-flood count, Public Assistance dollars and event records naming the place (starting figures from federal data).

County Public Assistance in B1-d also includes applicants filed under the county that are not matched to a jurisdiction row here (for example county departments filed under their own names, such as a highway department or emergency management agency, and state agencies, special districts and nonprofits), so the jurisdiction rows add up to less.

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 2025-04-10: $105,000 in county-coded records (26 records); $0 reported for the zone (24 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)
  • Future assets

Supports FEMA checklist item B2-a Vulnerability (county context)

Population 34,055; building value $6,606,968,237 and agriculture value $51,123,302 (total, not at risk).

National Risk Index rating Relatively Low; social vulnerability Very High; community resilience Relatively Moderate.

Supports FEMA checklist item B2-c Repetitive loss properties

Repetitive-loss properties, FMA definition (44 CFR 77.2): 1 repetitive loss, 2 severe repetitive loss. NFIP insurance definition: 15 and 2.

Mitigated 0; insured 3; NFIP data as of 2026-08-02. Counts by occupancy group and for each jurisdiction are in the packet.
