When a listing near Letha mentions a lot number, you'll need the Emmett plat map to make sense of it. This Emmett guide covers: where to request a copy, how a plat differs from a parcel map, and what to look for on the sheet.
Who keeps the Emmett plat map
Subdivision plats are recorded with the County Recorder (the county clerk serves as recorder), indexed by subdivision name.
Where the parcel data lives
Go first to the Gem County ArcGIS parcel map; it includes each tax parcel in the county, Ola included. If you only know roughly where the land is, pan along the nearest road and click the parcel itself, whether the land is near Letha or elsewhere in the county. With a lot near Ola, save the parcel ID from that panel; every clerk in the county asks for it first.
What the map can't tell you
Listed acreage is a tax-roll number; only a licensed surveyor establishes the real corners on land around Ola. For land near Ola, records update in batches, so a deed recorded last month might lag behind.
Where Emmett fits in
Emmett lies within Gem County, Idaho, and the county assessor maps its lots. As the county seat, Emmett hosts the courthouse, handy when you need recorded documents. On ground around Letha, city or town hall handles matters such as zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Land beyond the town limits out by Ola usually falls under county rules rather than the town's.
Recorded documents worth pulling
When the details count, pull the recorded deed through the County Recorder (the county clerk serves as recorder); the parcel line is a drawing of it. Inherited tracts near Letha may trace back through several deeds, so a title company can sort it out before a purchase.
Two different maps
The Gem County ArcGIS parcel map draws parcels for taxes, whereas the plat carries surveyed dimensions.
When a plat changes
An amended plat may change lots around Letha, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.
Field tips
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Letha, but coverage can be spotty out of town. A screenshot of the parcel near Letha with its ID is a good backup.
Legal descriptions in Idaho
Idaho follows the Public Land Survey System, so rural legal descriptions near Letha cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near Ola vary in size. Keep the legal description for land near Letha for any title or survey request.
Next door to Gem County
Gem County meets Ada County, Adams County, Boise County, Canyon County, and Payette County, and each of those keeps its own parcel map. Ground near Letha that runs to the line may be split across two assessors' files, so look at the adjacent map too. For a tract near Ola, our state page lists each bordering county map across Idaho.
Details on the Emmett plat map
Utility or drainage strips on a lot in Emmett can block a shed or pool; read the notes on the sheet.
Places you'll see on the map
Emmett is the county seat, home to the main records offices. You'll also find Letha and Ola, where town lots give way to larger tracts. About 21,071 people live in Gem County (Census Bureau estimate, 2023) across some 560 square miles. Gem County was formed in 1915, which matters when you trace an old farm's title. Features like Boise National Forest are easy to spot when you zoom out from Letha.
Requesting the plat
For property near Ola, many recorder offices offer an online index, otherwise call or visit with the reference; small fees are common.
Who handles what
Anything recorded against property around Letha come from the County Recorder (the county clerk serves as recorder), sometimes only in person. Building or septic questions for a lot near Letha go to planning, building or health offices, depending on whether the land is inside town limits.
Land outside a subdivision
Rural land near Ola that was never subdivided may have no plat at all; look for a recorded survey for land there.

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.
