Description of the flag

San Tan Valley is currently Arizona's newest municipality, incorporating on 17 September 2025 with Prop. 495 approving it on 5 August. The town's population in the past few years has surpassed 100,000 people. The town is mostly a commuter city, where residents go to Phoenix for work.
It should be noted that, although the town had some meetings before, all responsibility was handed over to the temporary town council on July 1. The first town council elections will happen in November.

The flag of San Tan Valley is white with its logo centered upon it. It does seem that the flag was adopted rather quickly for its use at the annual Parade of Flags which would take place in August (I found the first mention of its existence at the 15 July council meeting; I think it was adopted that same month, but it is also probable it was adopted in June).

The logo, according to [https://santanvalley.com/news/santanvalleynews/san-tan-valley-news/town-of-san-tan-valley-resident-wins-town-logo-contest-with-goldmine-mountain-design], was designed by Ben Martyn, being officially adopted on June 17, 2026; with the town's logo competition starting on February 1 and ending on May 1. Martyn received $2500 as the prize for winning: the contest had 175 total submissions from 66 residents. The finalist was decided on June 3, but then it was forwarded to the Maricopa Association of Governments to ensure it had proper design specifications.

The design is based on the silhouette of Goldmine Mountain and has a white V-shape from the Hunt Highway over it, which also stands for Valley; each section is in orange, gold, then blue. The highway is the main route for residents commuting; the author said that the V-shape also stood for progress, connection and the community's continued growth.
