Levy County, FL

Supports FEMA checklist item B1-a Hazard identification

15 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, ice storm and volcanic activity. That is the evidence for leaving them out of the plan.

Highest expected annual loss (NRI, modeled): Hurricane, Inland Flooding 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

• 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, Lightning, Strong Wind and Winter Weather: affects the whole county; national data give no location within it.
• Earthquake, Hurricane, Landslide, Tornado, Tsunami and Wildfire vary within the county; the packet lists the highest-rated census tracts for each.

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: 1.75 in hail, 2023-04-26; same size also recorded on 1994-08-27, 1998-06-23, 2003-07-18
• Thunderstorm Wind: 87 kt (100 mph) estimated gust, Thunderstorm Wind, 2020-04-20
• Tornado: F2 tornado, 1993-03-12, 1 mi path length (whole path, pre-1996), 80 yd wide, $50,000,000 property; crops not recorded (1993 dollars), 3 direct deaths, 10 direct injuries

Supports FEMA checklist item B1-d Previous occurrences

Federal declarations for this area: 44 declarations covering 34 separate hazard incidents counted in this packet; each with type, dates and county Public Assistance dollars.

New since the last plan (approved 2021-09-17): FM-5632-FL, DR-4834-FL, EM-3622-FL, DR-4828-FL, EM-3615-FL, DR-4806-FL, EM-3605-FL, DR-4734-FL, EM-3596-FL, DR-4680-FL, EM-3587-FL, DR-4673-FL and EM-3584-FL.

7 statewide declarations listed separately.

Hazards with no Storm Events record and no federal declaration are stated as such (9 of 18).

Storm Events history: 266 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 and Lightning
• Likely: Hurricane, Inland Flooding, Landslide, Strong Wind and Tornado
• Possible: 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 15 of the 18 hazards (12 tracts; rated tracts only).

9 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 2021-09-17: $228,000 in county-coded records (15 records); $10,000 reported for the zone (5 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 42,750; building value $5,277,998,010 and agriculture value $168,671,023 (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

Mitigated 2; insured 76; NFIP data as of 2026-08-02. Counts by occupancy group and for each jurisdiction are in the packet.
