View digital ‘Sanborn Maps’ for Colorado free from our public computers at Alamosa Public Library. What are ‘Sanborn Maps’? D.A.Sanborn’s Company was founded in 1867 in New York City. These maps were originally designed for fire insurance underwriters to determine the risk involved in insuring individual properties. They show the size, shape, and construction of buildings as well as street names, property boundaries, and building use. Currently, they may be used for a variety of purposes, including environmental site assessment, architecture, urban history, and genealogy. Come to Alamosa Public Library to view this valuable research tool if you are hunting for historical data of Alamosa or old buildings.
