Trying to understand lot lines near Aberdeen? What you want is the Hoquiam plat map, because the recorded plat shows how the land was divided. This Hoquiam guide covers: where to request a copy, plat versus tax map, and the details that matter to buyers.
Tracking down the Hoquiam plat map
For land around Aberdeen, the deed or parcel record often names the subdivision and plat reference; bring that to the recorder's office or its online index.
Getting to the right map
Your first stop is the Washington Current Parcels layer in ArcGIS Map Viewer; it maps every tax parcel around Cosmopolis and Ocean Shores. For acreage around Westport, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. Near Westport, a pop-up or side panel usually lists the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
Who handles what
Questions about value or the owner field for land near Ocean Shores belong with the County Assessor, the office behind the parcel record. Questions about what you can build around Montesano are for the local planning and health departments, town or county, depending on location.
Places you'll see on the map
Montesano holds the county offices, which is where the courthouse records live. Other places on the map include Aberdeen, Cosmopolis, Ocean Shores, and Westport, each with its own cluster of lots. About 77,290 people call Grays Harbor County home (Census estimate, 2023) on roughly 1,901 square miles. Grays Harbor County dates to 1854, and some chains of title near Ocean Shores are long. Features like Colonel Bob Wilderness make handy reference points on the map near Aberdeen.
Where Hoquiam fits in
Hoquiam is part of Grays Harbor County, Washington, which means parcel data comes from the county. If you're looking near Cosmopolis, the municipality handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Lots just outside the city limits toward Elma generally answers to county rules rather than the town's.
Replats and vacations
An amended plat may change lots around Aberdeen, search the index for replats of the same subdivision; street vacations show up in the records too.
Two different maps
The Washington Current Parcels layer in ArcGIS Map Viewer draws parcels for taxes, whereas the plat carries surveyed dimensions.
On site with the map
Most viewers work in a phone browser, useful out on a road near Cosmopolis, but coverage can be spotty out of town. A printout of the tract near Elma is a good backup.
Details on the Hoquiam plat map
For a tract near Cosmopolis, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
How land is described here
Washington uses the Public Land Survey System, which means a tract near Ocean Shores is described by section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though corrections make some sections near Aberdeen odd-sized. Write down the legal description for the tract near Westport when you talk to a surveyor.
Land on the county line
Grays Harbor County meets Jefferson County, Lewis County, Mason County, Pacific County, and Thurston County, and each of those keeps its own parcel map. Acreage along the edge near Aberdeen may be split in two county records, so look at the adjacent map before you assume the acreage. If the land is near Westport, our state page lists each bordering county map across Washington.
Where the recorded documents are
The map is an index, not the title: recorded deeds, subdivision plats and easements for land near Ocean Shores are filed with the County Auditor. On ground around Westport, use the instrument number shown in the record panel to skip a name search.
When there's no plat
Acreage around Ocean Shores outside a subdivision is often described by metes and bounds or survey description; look for a recorded survey for land near Montesano.
A word on accuracy
Listed acreage is an estimate; only a licensed surveyor establishes the real boundary on land around Westport. For land near Elma, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Ordering the Hoquiam plat map
For a parcel near Ocean Shores, many recorder offices offer an online index, otherwise call or visit with the reference; small fees are common.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
