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

17 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: hurricane. That is the evidence for leaving them out of the plan.

Highest expected annual loss (NRI, modeled): Avalanche, Earthquake and Inland Flooding.

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, Landslide, Tornado, Tsunami, Volcanic Activity 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 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.

Supports FEMA checklist item B1-d Previous occurrences

Federal declarations for this area: 1 declaration covering 0 separate hazard incidents counted in this packet; each with type, dates and county Public Assistance dollars.

No county-level plan row in FEMA data, so there is no approval date to count from.

4 statewide declarations listed separately.

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

Storm Events history: 602 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, Lightning and Winter Weather
  • Likely: Avalanche and Inland Flooding
  • Possible: Coastal Flooding, Cold Wave, Heat Wave, Ice Storm, Tsunami and Wildfire
  • Unlikely: Hail, Strong Wind, Tornado and Volcanic Activity

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 17 of the 18 hazards (1 tract; rated tracts only).

4 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.

No county-level plan row in FEMA data, so there is no approval date to count from.

Local data needed

  • 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)
