Closer to West Richland, City or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Acreage past the town limits near Benton City often follows county rules rather than the town's.

What the map can't tell you
Tax maps are drawn for assessment, not measured on the ground, so a tree line near Benton City may sit several feet off the line on screen. Out toward Benton City, records update in batches, so a deed recorded last month can take weeks to appear.
Backing up the map with records
The map is an index, not the title: deeds, subdivision plats and easements for land near West Richland are kept by the County Auditor. Long-held tracts around West Richland can go back through a long string of deeds, and a title company is worth hiring if money is changing hands.
Context from nearby lots
Look at adjoining lots near Prosser for context on nearby owners and uses; it helps with access and boundary questions.
