The official viewer behind the Silverton 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 Silverton.
The free map to start with
Go first to the ORMAP statewide tax lot viewer; it includes each tax parcel around Sublimity and Aumsville. For property near Sublimity, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. For a home near Gervais, write down the parcel ID while you have it open; every office in the county will want it.
Field tips
Most viewers work in a phone browser, useful out on a road near Woodburn, though signal can drop in rural spots. A printout of the tract near Woodburn helps when you meet an owner or agent.
Who handles what

Where Silverton fits in
Silverton lies within Marion County, Oregon, which means parcel data comes from the county. Closer to Keizer, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Lots just outside the town limits near Keizer usually falls under county rules, not municipal ones.
Searching the map
Acreage around Scotts Mills might not have a street number, which means panning to it and clicking. With a lot near Sublimity, searching by parcel number never misses, and it's printed on tax bills.
Troubleshooting the viewer
When the map won't open around Gervais, try a desktop browser or clear the cache; links occasionally change, and our directory page keeps the current one.

Around 346,741 people live in Marion County (Census estimate, 2023) across some 1,181 square miles. Marion County was organized in 1843, which matters when you trace an old farm's title.

A word on accuracy
Listed acreage is a tax-roll number; just a licensed surveyor can set the real corners for a parcel near Scotts Mills. For land near Sublimity, owner names and values update on a schedule, so a deed recorded last month might lag behind.

Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though corrections make some sections near Woodburn odd-sized. Keep the legal description for land near Woodburn before you request a deed or survey.

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.
