ADAS Calibration in Peoria, AZ

Peoria sits in the Salt River Valley, and extends into the foothills of the mountains to the north. William John Murphy, who had worked on the Arizona Canal, recruited settlers to begin a community in Arizona, many of them from Peoria, Illinois. Albert J. and Elizabeth Straw were the first to establish residency in November 1886. They were followed by William T. and Sylvia Hanna, James M. and Clara Copes, and James and Ella McMillan, all from Peoria, Illinois. An old desert road connecting Phoenix to the Hassayampa River near present-day Wickenburg was the only major transportation route in the area until 1887, when a new road was laid out. Named Grand Avenue, this road angled through the newly designed town sites of Alhambra, Glendale, and Peoria and became the main route from Phoenix to Vulture Mine. The settlers filed Peoria’s plot map with the Maricopa County recorder on May 24, 1897, naming the settlement after their hometown.

The original plot map of Peoria included east and west streets (from south to north) Monroe, Madison, Jefferson, Washington, Jackson, Lincoln, Grant, and Van Buren. Streets going north and south were (from west to east) Almond (present-day 85th Avenue), Peach (present-day 84th Avenue), Orange (present-day 83rd Avenue), Vine (present-day 82nd Avenue), and Walnut (present-day 81st Avenue). The plot was roughly from present-day Peoria and 85th avenues to Monroe Street and 85th Avenue to Monroe Street and 81st Avenue to 81st Avenue and south of the Desert Cove alignment. On August 4, 1888, the Territory of Peoria was granted a post office in its name and served a population of 27. Maricopa County supervisors defined the boundaries for School District Eleven, covering 49 square miles (130 km²), and the first class took place in an unoccupied brick store that faced north on Washington Street until Peoria’s first school building, a one-room structure completed in 1891.

Between 1891 and 1895, a spur line of the Santa Fe, Prescott and Phoenix Railway was placed through Peoria, along with Phoenix, Glendale, Alhambra, Hesperla, and Marinette. Peoria’s small depot on 83rd Avenue just off Grand Avenue was purchased by the city of Scottsdale in 1972 and now resides at McCormick-Stillman Railroad Park.
