About San Tan Valley
San Tan Valley is an unincorporated area of Pinal County. It borders several cities including Apache Junction, Mesa, Queen Creek, and Florence and has grown very rapidly over the last ten years. During the 2010 census, San Tan Valley had a population of roughly 81,000 and growing.
Currently it only has county services, which means that residents do not have city police or fire departments. San Tan Valley is currently serviced by Pinal County Sheriff and the Rural Metro Fire department (for an annual subscription fee). Parts of San Tan Valley are serviced by SRP (electric), Johnson Utilities (water/sewage), Southwest Gas and City of Mesa (gas), City of Queen Creek (water) and Right Away Disposal (trash). These services are differentiated by neighborhood.
San Tan Valley once sought to incorporate and become it’s own city, but this was struck down by the Florence town council. San Tan Valley has a major hospital, the Banner Ironwood Hospital, located at 37000 Gantzel Rd. It features forty-seven private rooms and focuses on emergency services, obstetrics, surgery and general medical care.
San Tan Valley acquired its name from the San Tan Mountains and has previously been called San Tan Heights, San Tan Foothills, Greater San Tan and simply the San Tan Area. Prior to becoming San Tan Valley, the community lacked any official name and residents used nearby Queen Creek for their mailing addresses. In July 2009, the area was issued different zip codes to split up these areas and the USPS was asked to provide the area with its own name. The community was give several choices but ultimately landed on San Tan Valley.
