The printed Polk County plat book and the online parcel map answer the same question, who owns the land near Willamina, in different ways. This guide covers finding a printed edition for Polk County, Oregon, and using the free parcel map in the meantime.
How to use the Polk County plat book
Think of the Polk County plat book as a bound, printed version of ownership: township pages, owner names on each tract, and road maps for places like Salem. Deeds and recorded plats, not the atlas, still govern land near Grand Ronde in the county.

What a plat book page shows near Independence
Plat book pages for Polk County generally include an index of owners, so you can find a family name near Salem without knowing the township. Acreage printed in a county atlas is approximate; the deed and a survey decide the real figure for a parcel near Salem.

Making your own atlas of Polk County
