When a listing near Benton City mentions a lot number, look up the Richland plat map it refers to. This Richland 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 Richland plat map
Recorded plats sit with the County Auditor, usually in a plat book or cabinet.
Getting to the right map
Property in and around Kennewick can be looked up on the Benton County parcel viewer, a viewer that needs no account. For a tract near Prosser, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. If the land is near Benton City, the parcel card typically gives the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
How land is described here
Washington uses the Public Land Survey System, which means a tract near West Richland is described by 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 Benton City vary in size. Write down the legal description for the tract near Prosser for any title or survey request.
When a plat changes
An amended plat may change lots around West Richland, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.
Backing up the map with records
The map is an index, not the title: deeds, subdivision plats and easements for land near Benton City are filed with the County Auditor. Long-held tracts near Benton City can trace back through many deeds, so a title company is worth hiring if money is changing hands.
Taking the map into the field
Most viewers work in a phone browser, which helps when you're standing on land near Prosser, though signal can drop in rural spots. A saved image of the lot near Benton City and its lines is a good backup.
City limits and county records
The city is part of Benton County, Washington, which means parcel data comes from the county, at least around Prosser. If you're looking near West Richland, City or town hall handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Land beyond the city limits toward Kennewick generally falls under county rules, not municipal ones.
When a parcel crosses a boundary
Benton County meets Morrow County, OR, Umatilla County, OR, Franklin County, Grant County, and Klickitat County, and each of those keeps its own parcel map. Acreage along the edge near Kennewick can show up across two assessors' files, so look at the neighboring map too. For land near Kennewick, our state page lists each bordering county map across Washington.
Getting answers from the right desk
If the acreage or value on a parcel near Benton City looks off go to the County Assessor, which maintains the tax roll. Zoning, permits and septic questions near Kennewick need the planning or permitting office, town or county, depending on location.
How a plat differs from the tax map
The tax map on the Benton County parcel viewer is a summary, but the recorded plat is what the deed relies on.
Details on the Richland plat map
Recorded easements around Kennewick can block a shed or pool; check the plat notes and any covenants.
Limits of the parcel data
Acreage on the record is an estimate; just a licensed surveyor sets the real lines for a parcel near Benton City. If the land is near Prosser, records update in batches, so a deed recorded last month might lag behind.
Places you'll see on the map
Prosser is the county seat, which is where the courthouse records live. You'll also find West Richland, Kennewick, and Benton City. Around 215,219 people call Benton County home (Census Bureau estimate, 2023) across about 1,700 square miles. Benton County dates to 1905, and some chains of title near Kennewick are long. Features like Hanford Reach National Monument help you orient on the aerial around Prosser.
Online indexes and office visits
With a lot near Prosser, many recorder offices offer an online index, while others require a visit or a request; copy fees are usually small.
When there's no plat
Acreage around West Richland outside a subdivision is often described by metes and bounds or survey description; look for a recorded survey for land near Kennewick.
