Cadastral Survey Plats

Cadastral surveys create, restore, mark, and define boundaries of parcels of land for describing individual ownership. The official survey plat is a graphic representation, drawn to scale, depicting the actual survey as described in the official field notes. The plat illustrates lot sizes and locations, bearings and distances, and corners, courses and distances of surveyed lines for rectangular, mineral, homestead surveys, and other metes and bounds parcels.

There are one or more cadastral survey plats for more of the townships in Oregon and Washington. The earlier cadastral plats are sometimes referred to as "GLO (General Land Office) plats" because these surveys were conducted by the General Land Office prior to the formation of the Bureau of Land Management. The Cadastral Survey Records available here represent the official Federal government survey records. All other survey information is found at the appropriate county offices.
