Fire Insurance maps are rich in historical information. Originally drawn to assess fire insurance liabilities for any property within city limits, these maps are more frequently used in preservation and restoration efforts. The maps are hand-drawn lithographs, usually include an index of streets and addresses, which show street names, property boundaries, the shapes of structures, identifying what materials buildings are made of, building uses, buildings proximity to fire hydrants, and the location of water and gas mains.
These large scale lithograph street plans were drawn at a scale of 50 feet to one inch, and printed on 53 x 64 cm sheets of paper. These sheets are usually bound, and published as a volume. Most maps in this collection are published by the Sanborn Map company, but some are not. As the city limits grew, revisions were made to the maps, with changes drawn by the Sanborn Map company, then sent to the insurance companies to be pasted over the original sheets. This collection include the cities in Butte County and throughout Northeastern California. For additional information, please consult the Meriam Library LIBGuide Fire Insurance Map Collection.
