Checking the Power County flood zone map step by step
The official source is FEMA's Flood Map Service Center: search an address around Pocatello, and choose the dynamic map. Vacant ground around Craters of the Moon National Monument and Preserve is still easy to locate: search the nearest road then click the parcel area.
Opening the official parcel viewer
Begin with the Power County ArcGIS parcel map; it includes every assessed parcel from Craters of the Moon National Monument and Preserve to Arbon Valley. When a rural tract has no street number, zoom in from Craters of the Moon National Monument and Preserve until the lines appear, then click inside the one you want. For a home near Pocatello, save the parcel ID before closing the panel; each clerk in the county will want it.
On site with the map
Most viewers work in a phone browser, useful out on a road near American Falls, but coverage can be spotty out of town. A printout of the tract near Roy keeps working without signal.
Decoding the flood zone labels
An AE label includes a base flood elevation (BFE), while plain Zone A does not; builders around Curlew National Grassland design to it. For property near Curlew National Grassland, minimal risk is not no risk: according to FEMA, floods happen outside mapped zones too.
Sections, lots and bearings
Idaho uses the Public Land Survey System, so rural legal descriptions near Arbon Valley cite section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Craters of the Moon National Monument and Preserve can be irregular. Write down the legal description for the tract near Craters of the Moon National Monument and Preserve when you talk to a surveyor.
Getting your bearings
American Falls holds the county offices, where most land records are kept. You'll also find Pocatello, Rockland, Arbon Valley, and Arbon, each with its own cluster of lots. Roughly 8,253 people live in Power County (Census estimate, 2023) spread over some 1,404 square miles. Power County was organized in 1913, so old deeds can run back a long way. Features like Caribou National Forest are easy to spot when you zoom out.
Land on the county line
Power County meets Bannock County, Bingham County, Blaine County, Cassia County, and Oneida County; every one of them runs a separate parcel map. Acreage along the edge near Craters of the Moon National Monument and Preserve may show up in two county records, so check the adjacent map as well.

What to request from a seller
Request about past flood claims for the house near Roy; an insurance quote early avoids surprises.
Use the county map alongside FEMA
When the zone clips a corner of a lot near Caribou National Forest, the structure's footprint is the key question.
Beyond the mapped zones
Creeks and ditches near Craters of the Moon National Monument and Preserve aren't always studied in detail, so walk the land after rain. Wetlands near Curlew National Grassland can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Lenders and permits
On ground around Caribou National Forest, ask for an Elevation Certificate: it records the building's elevation against the base flood. Building or adding on near Craters of the Moon National Monument and Preserve in a mapped zone often needs a floodplain permit; ask the local floodplain administrator early.
Before you lean on the lines
Tax maps are drawn for assessment, not surveyed, so a tree line near Craters of the Moon National Monument and Preserve often sits some distance off the line on screen. Records update in batches, so a fresh transfer around Craters of the Moon National Monument and Preserve might lag behind.
