Weighing a property around Eden? Checking the Jerome County flood zone map reveals whether FEMA puts it in a high-risk zone, and the lookup is free. This Jerome County guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and matching it with the county parcel viewer.
Checking the Jerome County flood zone map step by step
For a more interactive look, try the National Flood Hazard Layer viewer, which draws the zones over aerial imagery, and that holds around Hazelton too. Rural land near Eden with no street number can still be found: pan from the closest town then click the parcel area.
The viewer Jerome County publishes
Lots and tracts near Greenwood appear on the Idaho statewide Parcels layer in ArcGIS Map Viewer, which opens without registering. If the land is near Hazelton, 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 Eden, save the parcel ID before closing the panel; each records desk in the county uses it to find the file.
Who handles what
Recorded documents for a parcel near Hazelton come from the County Recorder (the county clerk serves as recorder), usually searchable by name or document number. Building or septic questions for a lot near Greenwood are for the local planning and health departments, depending on whether the land is inside town limits.
Decoding the flood zone labels
Out toward Eden, A and V zones are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. If the land is near Hazelton, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, is minimal risk.
What the map can't tell you
Around Greenwood, listed acreage is an estimate; only a licensed surveyor sets the real corners on the ground. For land near Caldron Linn, records update in batches, so a deed recorded last month can take weeks to appear.
Land on the county line
Jerome County meets Cassia County, Gooding County, Lincoln County, Minidoka County, and Twin Falls County; every one of them runs a separate parcel map. Acreage along the edge near Greenwood may be split in two county records, so open the neighboring map as well. On ground around Hazelton, our state page links every bordering county map for Idaho.
Water near Caldron Linn
Small streams around Eden may not have detailed mapping, so ask neighbors about past flooding. Wet ground around Caldron Linn is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Lining it up with the parcel map
FEMA doesn't draw property lines, so open the Idaho statewide Parcels layer in ArcGIS Map Viewer next to see exactly which lot near Eden you're looking at.
A short flood checklist
On ground around Hazelton, request for any Elevation Certificate before closing; an insurance quote early avoids surprises.
Places you'll see on the map
Jerome is the county seat, where most land records are kept. Smaller places on the map include Eden, Hazelton, Caldron Linn, and Greenwood. Roughly 25,479 people call Jerome County home (Census estimate, 2023) spread over roughly 598 square miles. Jerome County was formed in 1919, and some chains of title near Greenwood are long.
How land is described here
Idaho is laid out under the Public Land Survey System, so deeds around Hazelton reference sections and townships. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though real sections near Hazelton vary in size. Keep the legal description for land near Caldron Linn when you talk to a surveyor.
The paper trail behind a parcel
The map is an index, not the title: deeds, subdivision plats and easements covering ground around Greenwood are filed with the County Recorder (the county clerk serves as recorder). Long-held tracts around Hazelton may go back through a long string of deeds, so a title company is worth hiring before a purchase.
What a flood zone means for a buyer
For a parcel near Hazelton, ask for an Elevation Certificate: it compares the building to the BFE. Remodeling a house in a zone near Hazelton can trigger elevation rules; ask the local floodplain administrator before you plan.
