History

San Tan Valley derives its name from the nearby San Tan Mountains. San Tan Valley was picked as the name for the area based on an informal public poll commissioned by now former Pinal County Supervisor Bryan Martyn. Previously referred to as San Tan Heights, San Tan Foothills, Greater San Tan and simply the San Tan Area, the community lacked any official name and residents used nearby Queen Creek for their mailing addresses. To coincide with the addition of a new ZIP Code for the community on July 1, 2009, the
United States Postal Service The United States Postal Service (USPS), also known as the Post Office, U.S. Mail, or simply the Postal Service, is an independent agencies of the United States government, independent agency of the executive branch of the federal governmen ...
was petitioned to provide the area with a new name. As part of the initial request, "Bella Vista" name was submitted to the postal service, drawing the ire of some local residents who opposed the suggested name. In response, the Greater San Tan Area Coalition organized a non-binding vote on June 23, offering residents the opportunity to vote on a name for the community. The area, which had consisted primarily of undeveloped desert and agriculture prior to 2000, experienced considerable growth in the early part of the decade. As early as 2004, attempts to

after rural residents there expressed concern that allowing incorporation would accelerate the urbanization of the area. A subsequent effort in 2005 failed to gain traction. Following the renaming of the area in 2009, a renewed effort at incorporation sought to put the issue to a vote in 2010, this time with the support of Pinal County. The Town Council of Florence unanimously rejected a resolution that would have approved San Tan Valley's proposed boundaries over concerns of their allotment of state shared revenue.
