If a legal description for land in Lewiston cites a lot number, you'll need the Lewiston plat map to make sense of it. Covered here for the city: where to request a copy, plat versus tax map, and what to look for on the sheet for land near Peck.
Getting started with the Lewiston plat map
Subdivision plats are recorded with the County Recorder (the county clerk serves as recorder), usually in a plat book or cabinet.
Getting to the right map
Lots and tracts near Lapwai can be looked up on the Idaho statewide Parcels layer in ArcGIS Map Viewer, which opens without registering. When a rural tract has no street number, pan along US Route 195 and click the parcel itself. Near Peck, a pop-up or side panel usually lists the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
When there's no plat
Rural land near Culdesac that was never subdivided may have no plat at all; look for a recorded survey for land near Lapwai.
When a plat changes
An amended plat may change lots around Peck, so check for later filings; street vacations near Culdesac show up in the records too.
Using it on a phone
Most viewers work in a phone browser, handy when you're parked on a road near Lapwai, but coverage can be spotty out of town. A printout of the tract near Lapwai keeps working without signal.
How land is described here
Idaho is laid out under the Public Land Survey System, which means a tract near Peck is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Peck can be irregular. Keep the legal description for land near Peck before you request a deed or survey.
Lewiston and the county around it
Lewiston lies within Nez Perce County, Idaho, so its parcels are on the county's map. Lewiston is also the county seat, handy when you need recorded documents. With a lot near Lapwai, city or town hall handles matters such as zoning, permits and utilities inside its limits, while the county keeps the tax map. Acreage past the town limits out by Lapwai generally follows county rules, not municipal ones.
How a plat differs from the tax map
The tax map on the Idaho statewide Parcels layer in ArcGIS Map Viewer is a summary, but the recorded plat is what the deed relies on.
Limits of the parcel data
Acreage on the record is an assessed number; just a licensed surveyor establishes the real corners on land around Lapwai. Around Lapwai, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Nez Perce County in a few facts
Lewiston is the county seat, home to the main records offices. You'll also find Lapwai, Culdesac, and Peck, each with its own cluster of lots. Roughly 42,987 people live in Nez Perce County (Census Bureau estimate, 2023) spread over some 848 square miles. Nez Perce County was organized in 1864, which matters when you trace an old farm's title. Features like Clearwater River, Snake River, and Clearwater National Forest are easy to spot when you zoom out from Peck.
Recorded documents worth pulling
The map is an index, not the title: recorded deeds, subdivision plats and easements for land near Lapwai are kept by the County Recorder (the county clerk serves as recorder). Older tracts around Culdesac may go back through a long string of deeds, so a title company is worth hiring on a real sale.
Lots, blocks and easements
For a tract near Lapwai, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
Ordering the Lewiston plat map
The County Recorder (the county clerk serves as recorder) may have searchable images, while others require a visit or a request; copy fees are usually small.
Offices that can help
Recorded documents for a parcel near Culdesac come from the County Recorder (the county clerk serves as recorder), often with an online index. Building or septic questions for a lot near Culdesac are for the local planning and health departments, town or county, depending on location.
Neighboring parcel maps
Nez Perce County touches Clearwater County, Idaho County, Latah County, Lewis County, and Wallowa County, OR, all with their own assessor records. Acreage along the edge near Culdesac can be split in two county records, so look at the neighboring map too. The Platbookmapper state page lists each bordering county map across Idaho.
