For any lot around Rivergrove, the West Linn GIS map lays out parcel boundaries plus basic tax data. What this West Linn guide covers: where that map lives, the fastest ways to search, and the limits worth knowing.
Getting started with the West Linn GIS map
Parcel maps here are usually run by the county, not the town, which makes the ORMAP statewide tax lot viewer the main source for lots in West Linn.
Getting to the right map
Parcels around Johnson City are published on the ORMAP statewide tax lot viewer, free to use and open without a login. For land near Oregon City, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. If the land is near Johnson City, a pop-up or side panel usually lists the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
Backing up the map with records
For anything that matters, pull the recorded deed from the County Clerk; the parcel map near Oregon City only summarizes it. Older tracts around Gladstone can trace back through many deeds, and a title company earns its fee before a purchase.
When the map won't load
If the viewer stalls on a phone near Oregon City, try a desktop browser or clear the cache; the Platbookmapper county page tracks the current link.
Next door to Clackamas County
Clackamas County touches Hood River County, Marion County, Multnomah County, Wasco County, and Washington County, all with their own assessor records. A tract near the line by Gladstone can show up in two county records, so open the neighboring map before you assume the acreage. If you're looking near Rivergrove, the Platbookmapper state page lists each neighboring county map across Oregon.
Taking the map into the field
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Lake Oswego, so load it before you lose signal. A saved image of the lot near Lake Oswego and its lines is a good backup.
Reading the legal description
Oregon follows the Public Land Survey System, so deeds around Lake Oswego reference sections and townships. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Lake Oswego can be irregular. Write down the legal description for the tract near Oregon City when you talk to a surveyor.
Limits of the parcel data
Tax maps are drawn for assessment, not measured on the ground, so a fence near Oregon City often sits a few yards off the line on screen. For a parcel near Gladstone, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Where West Linn fits in
West Linn is part of Clackamas County, Oregon, so its parcels are on the county's map. In and around Rivergrove, City or town hall handles matters such as zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Land beyond the town limits near Oregon City generally falls under county rules, not municipal ones.
Saving what you find
Print or screenshot the parcel near Milwaukie with its ID visible, which helps later when you ask the assessor or a title company.
Three ways to find a parcel
For a house in West Linn, search the street address; for owner searches, try last name first. For a tract near Milwaukie, searching by parcel number never misses, and you'll find it on tax statements.
Who handles what
Deeds, mortgages and recorded plats for land near Oregon City come from the County Clerk, usually searchable by name or document number. Questions about what you can build around Oregon City need the planning or permitting office, depending on whether the land is inside town limits.
Places you'll see on the map
Oregon City is the county seat, which is where the courthouse records live. Other places on the map include Gladstone, Johnson City, and Lake Oswego, where town lots give way to larger tracts. Around 423,173 people live in Clackamas County (Census estimate, 2023) on roughly 1,871 square miles. Clackamas County was organized in 1843, and some chains of title near Lake Oswego are long.
Aerials, labels and overlays
For a parcel near Milwaukie, layer lists often include municipal boundaries, floodplain and sometimes zoning; availability varies.
Owner, value and acreage
If sale dates appear, they help gauge the market near Oregon City give a rough idea of values; an appraiser is the real authority.

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.
