PDF maps obtained from Lake County are approximate precinct boundaries drawn on the PLSS grid for county precincts and on the street map for Lakeview city precincts. These boundaries were adjusted to match address range assignments in the Lake County Address Library Report which serves as the legal definition of the precincts according to the Lake County Clerk. Precinct divisions across roads that span multiple rural precincts are generally defined by zip codes. Address ranges were further identified based on the Lake County tax lot parcel viewer.

Rural precinct boundaries in the shapefiles provided by Coos County and Union County were revised to match the updated PLSS cadastral grid in the Oregon GIS Framework obtained from the Oregon Spatial Data Library.
