Risk-assessment baseline packet. County FIPS 04009. Release 2026-10, data as of 2026-09-30.
Summary
Plan status as of 2026-09-30: No approved plan on record.
Update: FEMA tracker shows a plan in progress.
Highest expected annual loss (FEMA National Risk Index, modeled total; see B1-a): Inland Flooding ($9,037,003 a year), Heat Wave ($4,596,000) and Wildfire ($2,202,447).
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
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: coastal flooding, ice storm, tsunami and volcanic activity. That is the evidence for leaving them out of the plan.
Highest expected annual loss (NRI, modeled): Inland Flooding, Heat Wave and Wildfire.
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.
- Cold Wave, Drought, Hail, Heat Wave, Lightning, Strong Wind and Winter Weather: affects the whole county; national data give no location within it.
- 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 13 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: 4 in hail, 1958-03-12
- Thunderstorm Wind: 69 kt (79 mph) measured, Thunderstorm Wind, 2002-07-12; same speed and measurement basis also recorded on 2001-08-10
- Tornado: EF0 tornado, 2015-07-31, 0.58 mi within this county, 15 yd wide, $0 property; $0 crops (2015 dollars)
Supports FEMA checklist item B1-d Previous occurrences
Federal declarations for this area: 13 declarations covering 10 separate hazard incidents counted in this packet; each with type, dates and county Public Assistance dollars.
No approved plan on record, so there is no approval date to count from.
1 statewide declaration listed separately.
Hazards with no Storm Events record and no federal declaration are stated as such (7 of 18).
Storm Events history: 466 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: Cold Wave, Drought, Hail, Heat Wave, Inland Flooding, Strong Wind, Wildfire and Winter Weather
- Possible: Avalanche, Hurricane and Tornado
- 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 14 of the 18 hazards (9 tracts; rated tracts only).
4 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.
No approved plan on record, 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 38,453; building value $6,305,824,046 and agriculture value $79,930,432 (total, not at risk).
National Risk Index rating Relatively Low; social vulnerability Relatively 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, 1 severe repetitive loss. NFIP insurance definition: 3 and 1.
Mitigated 0; insured 0; NFIP data as of 2026-08-02. Counts by occupancy group and for each jurisdiction are in the packet.
