Before you buy or build near Driggs, look at the Teton County flood zone map: a mapped flood zone changes insurance, building rules and resale. This Teton County guide covers: finding the address on FEMA's map, reading the zone codes, and pairing it with the Idaho statewide Parcels layer in ArcGIS Map Viewer.
Getting started with the Teton County flood zone map
If the land is near Clementsville, the official source is FEMA's Flood Map Service Center: enter the street address, and choose the dynamic map. Vacant ground around Tetonia can still be found: zoom in from the nearest road then click the parcel area.
Getting to the right map
If the land is near Tetonia, the public parcel map for this area is the Idaho statewide Parcels layer in ArcGIS Map Viewer, and no login is needed to use it. For property near Darby, enter a street address, an owner's name or a parcel number, and the matching parcel lights up. If you're looking near Victor, save the parcel ID from that panel; every office in the county asks for it first.
What to request from a seller
Request for any Elevation Certificate on the property near Clementsville; an insurance quote early keeps the budget honest.
Backing up the map with records
The map is an index, not the title: deeds, plats and easements covering ground around Targhee National Forest sit with the County Recorder (the county clerk serves as recorder). Closer to Darby, have ready the book and page from the tax record and the lookup takes minutes.
Who handles what
Deeds, mortgages and recorded plats for land near Felt sit in the index kept by the County Recorder (the county clerk serves as recorder), often with an online index. Building or septic questions for a lot near Darby go to planning, building or health offices, and the answer depends on jurisdiction.
Decoding the flood zone labels
If the land is near Darby, any A or V zone are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. In and around Darby, minimal risk is not no risk: according to FEMA, floods happen outside mapped zones too.
Places you'll see on the map
Driggs is the county seat, home to the main records offices. Smaller places on the map include Tetonia, Victor, Felt, and Clementsville, where town lots give way to larger tracts. Roughly 12,549 people live in Teton County (Census estimate, 2023) spread over about 449 square miles. Teton County was organized in 1915, so old deeds can run back a long way. Features like Targhee National Forest help you orient on the aerial.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so pair it with the Idaho statewide Parcels layer in ArcGIS Map Viewer to see exactly which lot near Targhee National Forest you're looking at.
Using it on a phone
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Cache, but coverage can be spotty out of town. A printout of the tract near Targhee National Forest keeps working without signal.
Land on the county line
Teton County meets Bonneville County, Fremont County, Madison County, and Teton County, WY, all with their own assessor records. Acreage along the edge near Tetonia may show up in two county records, so open the adjacent map as well. If you're looking near Cache, the Platbookmapper state page links each bordering county map for Idaho.
Water near Clementsville
Small streams around Targhee National Forest may not have detailed mapping, so ask neighbors about past flooding. Wet ground around Targhee National Forest is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
What a flood zone means for a buyer
For a tract near Targhee National Forest, ask for an Elevation Certificate: it can change the insurance price a lot. Building or adding on near Targhee National Forest in a mapped zone usually means extra permit review; ask the local floodplain administrator early.
What the map can't tell you
Parcel lines are drawn for taxes, not measured on the ground, so the edge of a yard near Victor often sits a few yards off the line on screen. For land near Victor, records update in batches, so a deed recorded last month may not show yet.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
