When a listing near Elma mentions a lot number, the Montesano plat map is where those numbers come from. This Montesano guide covers: where to request a copy, plat versus tax map, and what to look for on the sheet.
The Montesano plat map: start here
For a lot in Montesano, the deed or parcel record often names the subdivision and plat reference; that makes the request quick.
Pulling up a parcel
Begin with the Washington Current Parcels layer in ArcGIS Map Viewer; it maps every tax parcel from McCleary to Aberdeen. For acreage around Elma, enter a street address, an owner's name or a parcel number, and the matching parcel lights up. For a tract near Elma, write down the parcel ID from that panel; every clerk in the county uses it to find the file.
Limits of the parcel data
Acreage on the record is an assessed number; just a licensed surveyor establishes the real corners for a parcel near Cosmopolis. Records update in batches, so a fresh transfer around Oakville can take weeks to appear.
When a parcel crosses a boundary
For a tract near Aberdeen, Grays Harbor County borders Jefferson County, Lewis County, Mason County, Pacific County, and Thurston County, all with their own assessor records. A tract near the line by Cosmopolis may show up in two county records, so check the adjacent map as well. Closer to McCleary, the Platbookmapper state page lists every bordering county map across Washington.
Grays Harbor County in a few facts
Montesano is the county seat, home to the main records offices. Smaller places on the map include Elma, Cosmopolis, Aberdeen, and McCleary, each with its own cluster of lots. Roughly 77,290 people call Grays Harbor County home (Census Bureau estimate, 2023) spread over some 1,901 square miles. Grays Harbor County dates to 1854, and some chains of title near Oakville are long. Places such as Colonel Bob Wilderness help you orient on the aerial around Oakville.
Offices that can help
Recorded documents for a parcel near McCleary are with the County Auditor, sometimes only in person. Zoning, permits and septic questions near Cosmopolis go to planning, building or health offices, depending on whether the land is inside town limits.
When a plat changes
Lots near McCleary can be combined or reconfigured by a replat, so check for later filings; vacated streets or alleys also get recorded.
Taking the map into the field
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Oakville, though signal can drop in rural spots. A saved image of the lot near Hoquiam and its lines keeps working without signal.
Montesano and the county around it
Montesano sits in Grays Harbor County, Washington, which means parcel data comes from the county. As the county seat, Montesano hosts the courthouse, handy when you need recorded documents. In and around McCleary, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Land beyond the town limits out by Hoquiam often answers to county rules rather than the town's.
How land is described here
Washington is laid out under the Public Land Survey System, so rural legal descriptions near Aberdeen cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though corrections make some sections near Oakville odd-sized. Write down the legal description for the tract near Oakville when you talk to a surveyor.
Deeds, plats and who keeps them
The map is an index, not the title: deeds, subdivision plats and easements for land near Oakville are kept by the County Auditor. If you're looking near Oakville, bring the instrument number listed on the parcel record so staff can find the deed fast.
How a plat differs from the tax map
Where lines don't match around Cosmopolis, the recorded plat and a survey control.
Reading the plat sheet
Easements on the plat near Aberdeen stay with the land when it sells; read the notes on the sheet.
Land outside a subdivision
Acreage around Elma outside a subdivision is often described by metes and bounds or survey description; the deed and any recorded survey describe it instead.
Getting a copy
Near Oakville, many recorder offices offer an online index, otherwise call or visit with the reference; small fees are common.
