Pulling up a parcel
Parcels around Richland are published on the Benton County parcel viewer, a viewer that needs no account. Without an address in hand, zoom in from Kennewick and click the parcel itself. For a home near Prosser, the parcel card typically gives the owner of record, acreage on the tax roll, the parcel number and often a sale date.
West Richland and the county around it
West Richland sits in Benton County, Washington, and the county assessor maps its lots. If the land is near Prosser, City or town hall handles matters such as zoning, permits and utilities inside its limits, while the county keeps the tax map.

How land is described here

Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Kennewick can be irregular.

When a parcel crosses a boundary
Benton County touches Morrow County, OR, Umatilla County, OR, Franklin County, Grant County, and Klickitat County; every one of them runs a separate parcel map. Ground near Richland that runs to the line can show up in two county records, so look at the adjacent map as well. In and around Benton City, the Platbookmapper state page lists every bordering county map across Washington.
The paper trail behind a parcel
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around Kennewick are filed with the County Auditor. Long-held tracts around Prosser may go back through many deeds, so a title company can sort it out on a real sale.
On site with the map
The parcel map usually runs in a mobile browser, useful out on a road near Kennewick, but coverage can be spotty out of town. A printout of the tract near Benton City is a good backup.
Reading a parcel record

Saving what you find

Limits of the parcel data
Acreage on the record is an estimate; just a licensed surveyor establishes the real corners for a parcel near Benton City. If you're looking near Kennewick, owner names and values update on a schedule, so a deed recorded last month might lag behind.
