Where the Keizer GIS map lives
In most places the county maintains the parcel layer, so for Keizer the go-to is the ORMAP statewide tax lot viewer.
Opening the official parcel viewer
Parcels around Aumsville can be looked up on the ORMAP statewide tax lot viewer, which opens without registering. On ground around Silverton, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. Around Aumsville, the record panel usually lists the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Keeping a record
Print or screenshot the parcel near Woodburn with its ID visible, which helps later when you ask the assessor or a title company.
Next door to Marion County
Marion County touches Clackamas County, Jefferson County, Linn County, Polk County, and Wasco County; every one of them runs a separate parcel map. Ground near Woodburn that runs to the line may be split across two assessors' files, so look at the adjacent map before you assume the acreage. In and around Woodburn, our state page lists every bordering county map across Oregon.
Keizer and the county around it
Keizer sits in Marion County, Oregon, and the county assessor maps its lots. If you're looking near Gervais, city or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Acreage past the city limits toward Turner generally answers to county rules instead.
Who handles what
Questions about value or the owner field for land near Gervais belong with the County Assessor, which maintains the tax roll. Questions about what you can build around Woodburn go to planning, building or health offices, town or county, depending on location.
Searching the map
Acreage around Woodburn might not have a street number, so zoom in from the nearest road and click the outline. If you're looking near Woodburn, searching by parcel number never misses, and you'll find it on tax statements.
Using it on a phone
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Gervais, but coverage can be spotty out of town. A screenshot of the parcel near Woodburn with its ID helps when you meet an owner or agent.
Deeds, plats and who keeps them
The map is an index, not the title: deeds, subdivision plats and easements for land near Gervais sit with the County Clerk. Inherited tracts around Gervais can sit on several deeds, so a title company can sort it out on a real sale.
Places you'll see on the map
Salem is the county seat, home to the main records offices. You'll also find Gervais, Turner, and Silverton. Roughly 346,741 people live in Marion County (Census Bureau estimate, 2023) on some 1,181 square miles. Marion County was formed in 1843, and some chains of title near Turner are long. Places such as Ankeny National Wildlife Refuge help you orient on the aerial around Gervais.
What the layers show
With a lot near Gervais, look in the layer list for city limits, flood hazard, zoning or soils; availability varies.
Limits of the parcel data
Listed acreage is a tax-roll number; just a licensed surveyor sets the real lines for a parcel near Aumsville. Around Woodburn, records update in batches, so a deed recorded last month might lag behind.
Reading the legal description
Oregon uses the Public Land Survey System, so rural legal descriptions near Salem cite section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Salem can be irregular. Keep the legal description for land near Silverton for any title or survey request.
Troubleshooting the viewer
When the map won't open around Woodburn, try a desktop browser or clear the cache; links occasionally change, and our directory page keeps the current one.
Owner, value and acreage
Sales history, if listed, helps with pricing near Aumsville are a useful starting point; 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.
