Fire Insurance Maps

Produced for use by insurance companies in assessing the value of and potential risks to properties.  These extremely detailed maps provide information about the size and number of stories of buildings, the materials used, number and type of windows in the buildings, commercial owners, and lot size.  They are extremely helpful when trying to create a visual image of a neighborhood.  However, insurance maps exist only for urban areas.
