Sanborn Fire Insurance Maps
The fire insurance maps were mainly designed to help fire insurance agents determine the degree of damage to a property and show accurate information to help them determine risks and establish premiums. The maps included street names, property boundaries and lot lines, and house and block numbers. Today, the maps are an invaluable guide to inner-city history, land use, and historic preservation.
