Weighing a property around Downey? Checking the Pocatello flood zone map reveals whether the lot falls inside a mapped floodplain, and no account is needed. Covered here for Pocatello: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Bannock County ArcGIS parcel map.
Checking the Pocatello flood zone map step by step
The official source is FEMA's Flood Map Service Center: search an address around Inkom, then open the map view for that panel. Rural land near McCammon with no street number is still easy to locate: zoom in from the nearest road and click inside the land.
Opening the official parcel viewer
Your first stop is the Bannock County ArcGIS parcel map; it maps each assessed parcel in the county, Lava Hot Springs included. For acreage around Lava Hot Springs, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. If the land is near Lava Hot Springs, write down the parcel ID while you have it open; each clerk in the county will want it.
A short flood checklist
Request for any Elevation Certificate on the property near Chubbuck; an insurance quote early keeps the budget honest.
Where Pocatello fits in
Pocatello is part of Bannock County, Idaho, so its parcels are on the county's map. Pocatello is also the county seat, which puts the County Recorder (the county clerk serves as recorder) close by. For a tract near Inkom, the municipality handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Lots just outside the city limits out by Lava Hot Springs often falls under county rules, not municipal ones.
A word on accuracy
Listed acreage is an estimate; just a licensed surveyor establishes the real lines for a parcel near Arimo. If the land is near Arimo, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Taking the map into the field
Most viewers work in a phone browser, handy when you're parked on a road near Inkom, though signal can drop in rural spots. A saved image of the lot near Chubbuck and its lines keeps working without signal.
Zones on the Pocatello flood zone map
For acreage around Arimo, any A or V zone are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. For property near McCammon, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so open the Bannock County ArcGIS parcel map next to confirm you have the right parcel near Inkom.
What a flood zone means for a buyer
For land near Inkom, get the Elevation Certificate if one exists: it compares the building to the BFE. Remodeling a house in a zone near Downey usually means extra permit review; call the permitting office early.
Sections, lots and bearings
Idaho follows the Public Land Survey System, so deeds around Arimo reference sections and townships. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near Lava Hot Springs odd-sized. Copy the legal description from the record for the parcel near Chubbuck when you talk to a surveyor.
Low spots and local drainage
Creeks and ditches near McCammon may not have detailed mapping, so look for water marks and debris lines. Wetlands near Arimo can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Neighboring parcel maps
Bannock County borders Bingham County, Caribou County, Franklin County, Oneida County, and Power County, and each of those keeps its own parcel map. Acreage along the edge near Arimo can show up in two county records, so look at the adjacent map as well. Our state page lists every neighboring county map across Idaho.
Offices that can help
Deeds, mortgages and recorded plats for land near Inkom come from the County Recorder (the county clerk serves as recorder), usually searchable by name or document number. Questions about what you can build around Chubbuck go to planning, building or health offices, and the answer depends on jurisdiction.
