Ahead of any purchase around Aberdeen, check the Blackfoot flood zone map: the zone on that map shapes insurance, permits and resale. Covered here for Blackfoot: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Idaho statewide Parcels layer in ArcGIS Map Viewer.
Checking the Blackfoot flood zone map step by step
The official source is FEMA's Flood Map Service Center: type an address near Shelley, and choose the dynamic map. Vacant ground around Shelley is still easy to locate: pan from the closest town and click the spot.
Where the parcel data lives
Begin with the Idaho statewide Parcels layer in ArcGIS Map Viewer; it covers each assessed parcel around Firth and Shelley. For land near Firth, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For property near Shelley, write down the parcel ID from that panel; each records desk in the county asks for it first.
Low spots and local drainage
Low-lying fields near Firth may not have detailed mapping, so walk the land after rain. Wetlands near Shelley can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
A short flood checklist
Request for any Elevation Certificate on the property near Aberdeen; getting a quote early avoids surprises.
Taking the map into the field
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Shelley, but coverage can be spotty out of town. A printout of the tract near Firth helps when you meet an owner or agent.
Where the recorded documents are
Before you sign anything, pull the recorded deed from the County Recorder (the county clerk serves as recorder); the viewer just points to it. If you're looking near Shelley, have ready the book and page listed on the parcel record and the lookup takes minutes.
Reading the legal description
Idaho uses the Public Land Survey System, so rural legal descriptions near Shelley cite section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though real sections near Shelley vary in size. Write down the legal description for the tract near Shelley when you talk to a surveyor.
City limits and county records
Blackfoot is part of Bingham County, Idaho, which means parcel data comes from the county. Blackfoot is also the county seat, handy when you need recorded documents. For acreage around Basalt, city or town hall handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Acreage past the town limits near Basalt often follows county rules instead.
Getting answers from the right desk
Recorded documents for a parcel near Basalt sit in the index kept by the County Recorder (the county clerk serves as recorder), often with an online index. Questions about what you can build around Shelley need the planning or permitting office, and the answer depends on jurisdiction.
Zones on the Blackfoot flood zone map
Closer to Basalt, any A or V zone are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. Closer to Shelley, a shaded X area marks moderate flood hazard, roughly the 100- to 500-year range; plain X, or C on older maps, is minimal risk.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so check the Idaho statewide Parcels layer in ArcGIS Map Viewer too to see exactly which lot near Basalt you're looking at.
A quick look at the area
Blackfoot is the county seat, which is where the courthouse records live. You'll also find Firth, Basalt, Shelley, and Aberdeen, where town lots give way to larger tracts. About 50,395 people live in Bingham County (Census estimate, 2023) spread over some 2,094 square miles. Bingham County was organized in 1885, and some chains of title near Basalt are long. Places such as Snake River Plain make handy reference points on the map near Basalt.
What a flood zone means for a buyer
Out toward Basalt, get the Elevation Certificate if one exists: it compares the building to the BFE. Remodeling a house in a zone near Aberdeen can trigger elevation rules; ask the local floodplain administrator before you plan.
Quick answers
Do I need to worry about flooding in Zone X for land near Firth?
Good question; X zones around Firth are lower risk, not no risk; FEMA notes that a large share of claims come from these areas.
Is AE a high-risk flood zone in Blackfoot?
In most cases, AE is a Special Flood Hazard Area with a published base flood elevation, which shapes building rules near Firth.
Where can I see the Blackfoot flood zone map for free?
It depends, but look up the spot near Shelley in FEMA's National Flood Hazard Layer viewer; no account is needed.
When is flood insurance required for land near Aberdeen?
Lenders generally require it for buildings near Shelley in a Special Flood Hazard Area when the loan is federally regulated or insured, in communities that take part in the NFIP.

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.
