Opening the Monmouth 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 Monmouth.
The viewer Polk County publishes
Go first to the ORMAP statewide tax lot viewer; it covers each tax parcel around Dallas and Independence. For acreage around Willamina, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. If you're looking near Dallas, the record panel normally shows the owner of record, acreage on the tax roll, the parcel number and often a sale date.
Monmouth, OR: the basics
Monmouth lies within Polk County, Oregon, and the county assessor maps its lots. Local government in Monmouth handles things like zoning, permits and utilities inside its limits, while the county keeps the tax map. Land beyond the town limits toward Willamina often follows county rules instead.
Searching the map
For a house in Monmouth, search the street address; owner search often wants the surname first. Out toward Dallas, searching by parcel number never misses, and it carries over to every office in the county.

What the layers show

What the map can't tell you
Listed acreage is an estimate; only a licensed surveyor establishes the real boundary for a parcel near Falls City. For property near Dallas, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Taking the map into the field

Inside the parcel card
