Before an offer near McCammon, look at the Chubbuck flood zone map: FEMA's zone label affects insurance, permits and resale. In this Chubbuck guide: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Bannock County ArcGIS parcel map.
Where the Chubbuck flood zone map lives
The official source is FEMA's Flood Map Service Center: type an address near Pocatello, then open the map view for that panel. A tract near Lava Hot Springs without an address can still be found: search the nearest road and click the spot.
Opening the official parcel viewer
Your first stop is the Bannock County ArcGIS parcel map; it maps each assessed parcel from Arimo to McCammon. Closer to Lava Hot Springs, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. Out toward McCammon, write down the parcel ID while you have it open; each records desk in the county uses it to find the file.
The paper trail behind a parcel
Before you sign anything, get the recorded deed through the County Recorder (the county clerk serves as recorder); the parcel map near McCammon only summarizes it. Older tracts around McCammon can sit on many deeds, so a title company is worth hiring on a real sale.
City limits and county records
Chubbuck is part of Bannock County, Idaho, so its parcels are on the county's map. For land near Pocatello, the municipality handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Acreage past the town limits near Downey often falls under county rules, not municipal ones.
Decoding the flood zone labels
For property near Arimo, any A or V zone are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. For a tract near Inkom, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X means minimal mapped risk.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so pair it with the Bannock County ArcGIS parcel map for the outline of the tract near Downey.
Bannock County in a few facts
Pocatello is the county seat, which is where the courthouse records live. You'll also find Inkom, Arimo, and Downey, where town lots give way to larger tracts. Around 90,400 people live in Bannock County (Census Bureau estimate, 2023) across about 1,112 square miles. Bannock County was organized in 1893, and some chains of title near McCammon are long. Places such as Portneuf River, Snake River, and Caribou National Forest make handy reference points on the map near Lava Hot Springs.
When a parcel crosses a boundary
Bannock County touches Bingham County, Caribou County, Franklin County, Oneida County, and Power County, and each of those keeps its own parcel map. A tract near the line by Downey may be split across two assessors' files, so open the neighboring map too. Our state page lists every bordering county map for Idaho.
Offices that can help
Recorded documents for a parcel near McCammon come from the County Recorder (the county clerk serves as recorder), sometimes only in person. Zoning, permits and septic questions near McCammon are for the local planning and health departments, depending on whether the land is inside town limits.
Insurance, lenders and building
For acreage around Downey, an Elevation Certificate from a surveyor helps: it compares the building to the BFE. Remodeling a house in a zone near Pocatello can trigger elevation rules; check with the county or town building office early.
Water near McCammon
Small streams around Inkom aren't always studied in detail, so walk the land after rain. Marshy spots near Arimo can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Lava Hot Springs, though signal can drop in rural spots. A saved image of the lot near Arimo and its lines is a good backup.
Questions to ask before you buy
Request whether the home has flooded on the property near Arimo; an insurance quote early keeps the budget honest.
Chubbuck: common questions
Is Zone X safe from flooding near McCammon?
Good question; Zone X near Lava Hot Springs means moderate (shaded) or minimal (unshaded) mapped risk; FEMA notes that a large share of claims come from these areas.
Is AE a high-risk flood zone for land near Arimo?
In most cases, an AE zone has a 1% annual chance of flooding and a base flood elevation, so builders near Inkom design to that elevation.
Why does the BFE matter near Arimo?
Short answer: the BFE is printed in AE zones on FEMA's map; surveyors near Lava Hot Springs use it often.
How often are flood maps updated in Chubbuck?
For most people, zones near Downey can shift when FEMA updates a panel; check the effective date on the panel.
How do I save a parcel from the viewer around McCammon?
Most viewers have a print or export tool, and it's worth keeping the parcel ID visible for land near Inkom.
