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): Inland Flooding, Lightning and Drought.
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 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: 4.5 in hail, 2014-06-12; same size also recorded on 2011-04-20
- Thunderstorm Wind: 84 kt (97 mph), measurement type not recorded, Thunderstorm Wind, 1984-10-21
- Tornado: F3 tornado, 1969-05-06, 41.6 mi path length (whole path, pre-1996), 200 yd wide, $25,000 property; crops not recorded (1969 dollars)
Supports FEMA checklist item B1-d Previous occurrences
Federal declarations for this area: 21 declarations covering 13 separate hazard incidents counted in this packet; each with type, dates and county Public Assistance dollars.
New since the last plan (approved 2013-02-27): DR-4935-TX, EM-3649-TX, DR-4879-TX, DR-4705-TX, DR-4586-TX, EM-3554-TX, DR-4485-TX, EM-3458-TX and DR-4416-TX.
10 statewide declarations listed separately.
Hazards with no Storm Events record and no federal declaration are stated as such (7 of 18).
Storm Events history: 380 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 and Lightning
- Likely: Cold Wave, Drought, Ice Storm, Inland Flooding, Landslide, Strong Wind, Tornado and Winter Weather
- Possible: Hurricane 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 (2 tracts; rated tracts only).
2 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.
Storm Events damage since 2013-02-27: $19,100,000 in county-coded records (111 records); $1,000,000 reported for the zone (75 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
- Texas A&M Forest Service TxWRAP for wildfire risk; Texas State Hazard Mitigation Plan hazard list for B1-a exclusions.
Supports FEMA checklist item B2-a Vulnerability (county context)
Population 4,271; building value $2,842,333,326 and agriculture value $13,972,375 (total, not at risk).
National Risk Index rating Very Low; social vulnerability Very High; community resilience Relatively Low.
Supports FEMA checklist item B2-c Repetitive loss properties
