Trying to understand lot lines near Rock Island? What you want is the East Wenatchee plat map, as it records the lot layout that deeds refer to. Covered here for East Wenatchee: where to request a copy, how a plat differs from a parcel map, and what to look for on the sheet.
Getting started with the East Wenatchee plat map
For land around Mansfield, look for the plat book reference on the parcel record; bring that to the recorder's office or its online index.
Pulling up a parcel
Go first to the Douglas County ArcGIS parcel map; it includes each tax parcel in the county, Waterville included. With a lot near Mansfield, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. For a home near Bridgeport, the record panel typically gives the owner of record, assessed acreage, the parcel number and often a sale date.
Which office to call
If the acreage or value on a parcel near Coulee Dam looks off belong with the County Assessor, since that office keeps the assessment data. Zoning, permits and septic questions near Rock Island are for the local planning and health departments, town or county, depending on location.
Where East Wenatchee fits in
East Wenatchee sits in Douglas County, Washington, and the county assessor maps its lots. On ground around Coulee Dam, the municipality handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Acreage past the town limits out by Coulee Dam often answers to county rules, not municipal ones.
How a plat differs from the tax map
When the two disagree for a lot near Coulee Dam, go with the plat and a surveyor's work.
Amended plats
An amended plat may change lots around Waterville, search the index for replats of the same subdivision; street vacations near Coulee Dam show up in the records too.
When a parcel crosses a boundary
Douglas County meets Chelan County, Grant County, Kittitas County, and Okanogan County; every one of them runs a separate parcel map. A tract near the line by Bridgeport may be split in two county records, so check the adjacent map as well. If you're looking near Waterville, the Platbookmapper state page links every bordering county map across Washington.
Places you'll see on the map
Waterville is the county seat, which is where the courthouse records live. You'll also find Rock Island, Bridgeport, and Coulee Dam, each with its own cluster of lots. Around 44,798 people live in Douglas County (Census Bureau estimate, 2023) across some 1,819 square miles. Douglas County was organized in 1883, which matters when you trace an old farm's title.
Legal descriptions in Washington
Washington uses the Public Land Survey System, which means a tract near Coulee Dam is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though corrections make some sections near Waterville odd-sized. Copy the legal description from the record for the parcel near Rock Island for any title or survey request.
The paper trail behind a parcel
The map is an index, not the title: deeds, subdivision plats and easements for land near Bridgeport are filed with the County Auditor. For land near Bridgeport, have ready the document number listed on the parcel record and the lookup takes minutes.
Lots, blocks and easements
Easements on the plat near Coulee Dam can block a shed or pool; read the notes on the sheet.
Limits of the parcel data
The acreage figure is an assessed number; only a licensed surveyor can set the real corners for a parcel near Bridgeport. For a tract near Bridgeport, records update in batches, so a deed recorded last month might lag behind.
On site with the map
Most viewers work in a phone browser, handy when you're parked on a road near Coulee Dam, but coverage can be spotty out of town. A printout of the tract near Rock Island is a good backup.
Ordering the East Wenatchee plat map
The County Auditor may have searchable images, while others require a visit or a request; small fees are common.
Land outside a subdivision
Acreage around Bridgeport outside a subdivision may have no plat at all; look for a recorded survey for land near Coulee Dam.
