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
16 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: tsunami and volcanic activity. That is the evidence for leaving them out of the plan.
Highest expected annual loss (NRI, modeled): Inland Flooding, Hurricane and Cold Wave.
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, Hurricane, Landslide, Tornado 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 15 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: 2.75 in hail, 2011-06-08
- Thunderstorm Wind: 126 kt (145 mph) measured, Thunderstorm Wind, 2000-05-18
- Tornado: F1 tornado, 1992-07-31, 22.7 mi path length (whole path, pre-1996), 73 yd wide, $2,500,000 property; crops not recorded (1992 dollars)
Supports FEMA checklist item B1-d Previous occurrences
Federal declarations for this area: 27 declarations covering 19 separate hazard incidents counted in this packet; each with type, dates and county Public Assistance dollars.
Plan 109877 was approved by FEMA on 2026-03-30 but is not yet adopted here, so no since-plan counts are given.
5 statewide declarations listed separately.
Hazards with no Storm Events record and no federal declaration are stated as such (5 of 18).
Storm Events history: 1,441 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: Coastal Flooding, Hail, Landslide, Lightning, Strong Wind and Winter Weather
- Likely: Cold Wave, Drought, Heat Wave, Inland Flooding and Tornado
- Possible: Avalanche, Hurricane, Ice Storm and Wildfire
- Unlikely: Earthquake
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 16 of the 18 hazards (82 tracts; rated tracts only).
13 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.
Plan 109877 was approved by FEMA on 2026-03-30 but is not yet adopted here, so no since-plan counts are given.
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 295,788; building value $69,887,763,089 and agriculture value $56,518,448 (total, not at risk).
National Risk Index rating Relatively Moderate; social vulnerability Relatively Low; community resilience Relatively High.
Supports FEMA checklist item B2-c Repetitive loss properties
Repetitive-loss properties, FMA definition (44 CFR 77.2): 3 repetitive loss, 19 severe repetitive loss. NFIP insurance definition: 100 and 18.
Mitigated 1; insured 34; NFIP data as of 2026-08-02. Counts by occupancy group and for each jurisdiction are in the packet.
