What this tracks
This dataset maps wildfire hazard potential across Tennessee using a grid of 50-square-kilometer hexagons to show where wildfires are most likely to occur.
Why it matters to you
If you’re buying property, planning outdoor activities, or running a business in Tennessee, this data helps you understand your wildfire risk before making decisions. Homeowners can use it to determine if they need additional fire insurance or defensible space around their property. Business owners in high-risk areas might invest in fire suppression systems or evacuation planning.
How to read this data
GRID_ID — A unique identifier for each hexagonal area, shown as codes like “AM-20” that help locate specific grid sections across Tennessee. gridcode — A numerical value like 63 that represents the calculated wildfire hazard level for that hexagon. ClassCode — A simplified risk category number (like 4) that groups areas into broader hazard classes, making it easier to compare relative wildfire danger between different locations.
Where this leaves you
This dataset doesn’t let you look anything up by your address, but it’s still a window into how the state operates. Read it to understand the scope of the program and what the official records contain; the state’s own interactive map (linked on this page) shows the locations involved.
