Somewhere between Barlow and the Multnomah County line is a tract you want to know more about. The Clackamas County GIS map is the free, official place to start.
Below are the official links, a quick tour of Clackamas County's towns and land, and the steps for turning a parcel click into a reliable answer.
How to use the Clackamas County GIS map
Open the statewide ORMAP statewide tax lot viewer and zoom toward Damascus; Clackamas County's parcels are part of that layer. Zoom to Clackamas County and click a tax lot to see the map number, then follow up with the county's assessment records. If the official link ever moves, the Clackamas County page on Platbookmapper keeps the current version.
Who uses the Clackamas County parcel map
The same map serves very different jobs around Barlow. Buyers new to Barlow often pull the neighbors' parcels too, to see how big the surrounding lots are and who owns them. For a new build outside Gladstone, the parcel record supplies the lot size and legal description a site plan needs. Vacant-lot hunters working the edges of Damascus look for parcels with no structures and owners who live out of the area. If you hunt the country around Beavercreek, the owner layer tells you who to ask and where the next property begins.
Getting oriented in Clackamas County
Most of the platted lots cluster in and around Oregon City (the county seat) and Barlow, Canby, Damascus, and Estacada. Out in the countryside, Beavercreek, Boring, and Clackamas appear as small knots of lots along the road network. Organized in 1843, and named for Clackamas people, Clackamas County has a long paper trail, and early deeds may cite landmarks that no longer exist. About 423,173 people lived in Clackamas County in 2023, according to Census Bureau estimates, on roughly 1,871 square miles. Much of Clackamas County is built out, so the parcel map is busiest with subdivision lots, though rural edges and undeveloped tracts still turn up.
Work and land use in Clackamas County
By the Census Bureau's 2022 count, 12,830 business establishments operated in Clackamas County. Construction had the most, followed by health care and social assistance and professional and technical services. The local economy leans harder than average on leather product manufacturing, transportation equipment manufacturing, and primary metal manufacturing. Manufacturing jobs in the county help keep house lots and small acreage in demand, including around Oregon City. For a land buyer in Clackamas County, that mix hints at who your neighbors and competing bidders are likely to be.
How to find property lines in Clackamas County
A Clackamas County GIS map is built for assessment, not construction. In Clackamas County, as in most places, the lines are a best fit of old deed calls onto modern aerial photos. Legal descriptions in Oregon usually lean on the section grid, so learning to read 'NE 1/4 of Section 12' pays off quickly around Barlow. For rural ground near Beavercreek, a recorded survey or a new one is the only reliable source for the true line.
Acreage and vacant lot search
How to work the Clackamas County GIS map for open land:
- With imagery on, zoom to the edge of Gladstone where subdivisions give way to open ground.
- Open the record for each empty tract near Gladstone and note whether the owner's mailing address is outside Clackamas County.
- Compare land values on similar Clackamas County tracts to see whether an asking price is in the ballpark.
- Make sure the parcel near Gladstone actually touches a public road, and ask how it's reached if it doesn't.
- Last, call the Clackamas County planning or health office about permits, septic and floodplain before you commit.
Before you buy near Gladstone, read how to tell if land is buildable.

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.
