Sanborn Fire Insurance maps are meticulously detailed, large-scale lithographed, color-keyed street maps. Sanborn Maps helped insurance agents in the late 19th and early 20th centuries determine the degree of fire hazard associated with a particular property. Sanborn Fire Insurance maps typically focus on the business districts within communities. Features include street names, street and sidewalk widths, property boundaries, locations of fire hydrants, locations of water and gas mains, and the names of most public buildings, churches and companies. The maps also document the strength of the local fire department and the presence of fire hazards such as blacksmith forges, large baker's ovens or stored kerosene, and the existence of firefighting equipment, cisterns or community water works. Rivers, canals, railroad corridors and similar features are also noted. Each map provides a detailed assessment of the buildings within a district. Assessments include an outline of each building and outbuilding, the size and number of stories of every building, the location of windows and doors, fire walls, and indications of sprinkler systems. They note the nature of the business or businesses which occupied individual buildings, sometimes even particular room uses. They list the type of construction and the composition of building materials including the framing, flooring, and roofing materials.
