Contains more than 660,000 Sanborn maps that chart the growth and development of more than 12,000 U.S. towns and cities over a century. Sanborn maps are large-scale plans of a city or town, drawn at a scale of 50 feet to an inch. They were created to assist fire insurance companies as they assessed the risk associated with insuring a particular property.
The maps typically include building outline, size and shape, windows and doors, street and sidewalk widths, boundaries, and property numbers. Plans often include details on construction materials and building use and also depict pipelines, railroads, wells, water mains, dumps, and other features likely to affect the property's vulnerability to earthquake, fire, and flood.
