What the packet contains
Sections in FEMA checklist order. Each heading names the review item its tables support; whether the item is satisfied is decided by the plan and its reviewers. Full tables are in the downloads above.
Supports B1-a Hazards
15 of the 18 National Risk Index hazards apply here; omission evidence is shown only where NRI rates a hazard "Not Applicable", no federal declaration names it and Storm Events has no record of it since 1996.
Highest expected annual loss (NRI, modeled): Inland Flooding, Wildfire and Lightning.
Also check locally (not covered by NRI): 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 and expansive soils.
Check your state hazard mitigation plan's hazard list for this county; explain any hazard you drop.
Supports B1-b Location
