Look up the Bingham County flood zone map step by step
Open the FEMA Flood Map Service Center and type a county street address, say one in Firth. Download the FIRM panel FEMA lists as effective for that part of Bingham County. For an interactive view of the county, try FEMA's National Flood Hazard Layer viewer; zoom to the tract close to Basalt and click. Then open the Idaho statewide Parcels layer in ArcGIS Map Viewer for Bingham County to confirm the parcel near Firth. If the Bingham County viewer has a floodplain layer, treat it as a convenience copy and confirm on FEMA's map.
Step one: the free Bingham County viewer
There's no separate Bingham County parcel site to hunt for; the Idaho statewide Parcels layer in ArcGIS Map Viewer carries the county's parcels along with the rest of Idaho. Use the search box for an address in Blackfoot or a parcel number, or simply zoom in and click a tract close to Shelley. Bookmark our Bingham County page too; it tracks the official Idaho link if it moves and lists the maps around Blackfoot.
High, moderate and minimal risk in Bingham County
On the FIRM covering Bingham County, zones that start with A or V are Special Flood Hazard Areas, meaning FEMA estimates a 1-percent annual chance of flooding. Zone AE near Basalt means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. Land near Basalt in shaded X (Zone B on older maps) is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Unshaded X (or C) on the Bingham County panel means minimal risk.
Creeks, rivers and low ground in Bingham County
Parcels touching Snake River Plain deserve a FEMA check before anything else in Bingham County. Waterfront and bottomland parcels near Firth often carry a zone along one edge, so check where the buildable part sits. A low spot on a Bingham County tract outside any mapped zone can still flood; FEMA says moderate- and low-risk areas still carry risk.
Seller questions about flood history
For a house near Firth, ask the seller for any elevation certificate on file and the current flood insurance declarations page. An agent working in Bingham County can quote flood coverage once you know the zone for the lot near Firth.
What a flood zone means for a Bingham County buyer
Insurance is the practical stake for a Bingham County buyer. If a house near Basalt falls inside an A or V zone and carries a federally backed mortgage, a flood policy becomes a loan condition, as long as Bingham County or the town participates in the NFIP. For a county home in shaded or unshaded X, coverage is optional; pricing a policy for land near Basalt is still worth a call. If a building near Basalt sits above the flood line, the landowner can ask FEMA for a Letter of Map Amendment (LOMA); a surveyor near Basalt can supply the elevation data. Building or filling inside a mapped zone near Firth often requires a permit and an elevation check, and the building office serving Basalt explains the steps.
