Sanborn maps are large scale maps of urban areas. They were created to document the fire risk associated with a particular property by showing the size, shape, and construction details of structures on the property. Sanborn maps also indicate widths and names of streets, property boundaries, building use, and house and block numbers. The original maps were drawn at a scale of 50 feet to one inch (1:600), so they are a rich source of historical detail.
Yakima County Plat Maps
A collection of plat maps created by the Yakima County Assessor’s Office, hand-drawn in ink on acetate film, primarily in the 1960s and ’70s, using the Township and Range grid developed by the Public Lands Survey System (PLSS). Because these maps pre-date computer-based GIS technologies, they provide historical data over a broader area of the county than is available from today’s highly detailed GIS mapping systems. Available by appointment at Yakima Central Library.
