A Short History

The Rural Property Inventory project started in 1935 and continued through 1942. In addition to providing jobs for out of work surveyors and engineers, the project was designed to give state and local governments a uniform basis for assessing property taxes. In Michigan, approximately two thousand white collar workers prepared 8″ x 10″ cards for each individual land parcel outside of Wayne County. The cards provided information about land use, soil type, topography and crops grown. Cards usually also included sketches of any structures on the property, along with a diagram of the property and surrounding roads. A guide to abbreviations and codes used on the cards is available in the Archives of Michigan reading room.
