Peoria is a city in Maricopa and Yavapai counties in the State of Arizona. Most of the city is located in Maricopa County, while a tiny portion in the north is in Yavapai County. It is a major suburb of Phoenix. According to 2010 Census Bureau releases, the population of the city is 154,065. Peoria is currently the sixth largest city in Arizona for land area, and the ninth largest for population. It was named after Peoria, Illinois. The word "peoria" is a corruption of the Illini word for "prairie fire." It is the spring training home of the San Diego Padres and Seattle Mariners who share the Peoria Sports Complex. In July 2008, Money magazine listed Peoria in its Top 100 Places to Live. 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. Four farming families left Illinois that fall to relocate to what is now Peoria, Arizona. 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.
