Regarding The Riordan Building. Excerpts from the National register nomination:
One of only 3 buildings in survey area associated with the development and growth of one of the states most important industries. Served as the offices of the Arizona Lumber and Timber Company from 1900 through 1932.
[Chicago lumberman Edward Everett] Ayer hired fellow Chicagoan D.M. Riordan as general manager of his Flagstaff operation. In 1884 Riordan enticed his two brothers, T.A. and M.J. Riordan, to join him in Flagstaff with positions in the Ayer Lumber Company. By 1887, Ayer negotiated the sale of the company to the Riordans who reorganized it as the Arizona Lumber Company and eventually as the Arizona Lumber and Timber Company
Despite a fire which destroyed the mill in 1887 and another devastating fire in 1897, the Arizona Lumber and Timber Company became a dominant force in the lumber industry statewide.
Technological advances during the mid-1920s allowed the Arizona Lumber and Timber Company to double its production without doubling its employees. Competition for local and regional markets intensified during this period until the stock market crash of 1929. Sales dropped sharply and the Arizona Lumber and Timber Company closed its mill in 1930. It opened the operation again in 1931 on a part-time basis but business had dropped almost 75% below that of 1928. In 1933, the Riordans liquidated their lumber interests to make other investments.
