Latest News in San Tan Valley, AZ

San Tan Valley residents air hopes and fears for incorporation at open house


San Tan Valley residents got their first opportunity to voice their concerns and desires regarding an effort to incorporate the area as Arizona's newest city.

State of play: Opinions were mixed as board members from STV Inc. 2024 presented their first draft map of the proposed city boundaries to about 50 people at an open house Tuesday evening at San Tan Heights Community Center.

Catch up quick: STV Inc. 2024 hopes to refer an incorporation plan to the ballot next year.

Why it matters: Supporters say incorporation would give residents more control over local affairs, better services and more authority over their own tax revenue, which is collected and spent by the state and Pinal County.

What they're saying: "I think the people need to know what it's going to cost them," said resident Jerry Pierce.

Zoom in: Others who were more supportive of incorporation expressed concerns that their tax revenues are going to the county or neighboring Queen Creek, home to many of the businesses they patronize.

Meanwhile, one resident said San Tan Valley has the worst water in the area, and questioned whether an incorporated city would change that.

Between the lines: Some attendees' biggest concern with the proposed boundaries was they weren't within them.

What's next: STV Inc. 2024 will hold open houses on July 20 at the Pinal County Offices and Sept. 30 at San Tan Heights Community Center.

There's a new push to incorporate San Tan Valley. What's changed since the last attempt

Voters may get a chance to decide in 2024 whether San Tan Valley, Pinal County's largest unincorporated community, will become a municipality.

A group of San Tan Valley residents has formed a committee, STV Inc. 2024, to petition for the county area to incorporate, according to an April 12 notice of intent delivered to the Pinal County Board of Supervisors.

During a Wednesday meeting, a member of the group told supervisors that organizers intend to speak with neighbors in the community and nearby cities to obtain feedback and develop plans.

Tyler Hudgins, one of the residents behind the effort, said the boundaries of the proposed municipality remain undetermined. He said residents seek incorporation to secure localized control over tax dollars and address issues such as "water, transportation and development."

As an unincorporated area, San Tan Valley is dependent on county government and services, so the board currently determines how those problems are tackled. But the community has boomed as housing prices have soared in metro Phoenix, and residents and county officials have long expressed concerns that it's outgrown its roads, services and unincorporated status. It has a rapidly growing population of about 100,000, per the U.S. Census Bureau.

That entire San Tan Valley population may not be within the final boundaries of the incorporation bid. Still, it's likely that the community would become Pinal County's largest city if it were to incorporate. Currently, the city of Maricopa holds that title, with a population of about 60,000.

Two potential paths to incorporation

Hudgins stressed that the incorporation process is still in early stages, calling the committee "exploratory."

The group is currently arranging meetings with officials from Queen Creek, Florence, Mesa and Apache Junction, he said.

As the group meets with neighbors and stakeholders, Hudgins and other members will work to develop proposed boundaries, create a budget and plan out services for the potential municipality. Once a formal plan has been put together, the committee may seek incorporation via a county supervisors vote or by an election of San Tan Valley voters.

Incorporation by county supervisors would require committee organizers to produce signatures of two-thirds of the registered voters within the boundaries of the area. Incorporation via a direct election requires only 10% of registered voters to sign.

The group's notice of intent states that the committee will endeavor to place the initiative on the November 2024 ballot and "allow the community to determine the future of San Tan Valley."

In that case, the incorporators will need to submit their signatures to county supervisors, who will tally up the number of valid ones. If the group reaches the 10% threshold, the board will greenlight the election and voters within the boundaries of the proposed municipality will choose whether to incorporate.

A history of failed incorporation attempts

Previous incorporation efforts in San Tan Valley have crashed and burned before making it onto voters' ballots.

The most recent, in 2018, was hamstrung when the developer of Encanterra announced it would not give permission for that community to be included in the proposed municipality. At that time, state law dictated that the incorporation process required organizers to notify developers and homeowner associations individually. Any entity not notified could opt out of the proposed boundaries and potentially kill the incorporation effort.

That provision was changed last year, and now, incorporators must notify all parties by getting their efforts on a meeting agenda of the county Board of Supervisors six months in advance. Entities may still opt out, but they can no longer kill the incorporation effort.

Other bids to incorporate San Tan Valley faced opposition from nearby cities. State law previously allowed an existing city or town within six miles of a proposed incorporation to block it, a provision that was removed in 2017.

In the meantime, the unincorporated community's neighboring municipalities have annexed chunks of the area into their boundaries.

SAN TAN VALLEY, AZ — With the San Tan Mountains as a backdrop, San Tan Valley is one of the fastest-growing communities in Arizona.

"We only had two roads coming in and out and still had cows and loved it," said Evelyn Carr. "But it's definitely time for us to grow up."

Carr has lived in San Tan Valley for 17 years and she believes it's time for it to become a city.

"I believe that it's a good idea for us to incorporate because we need our roads. Control of what's going on in our city," she said.

Carr is among a growing number of San Tan Valley residents who want their community to become a city.

In April, an organization called STV Inc. 2024 notified Pinal County it will try to get San Tan Valley recognized as a city.

"We have 100,000 residents in San Tan Valley, 100,000 plus. It's the largest unincorporated area and Pinal County is not set up to run a city," said Tyler Hudgins, a member of the STV Inc. 2024 board and one of the leaders in the effort.

Geographically, Pinal County is the size of the state of Connecticut.

When it comes to the distribution of county tax dollars, San Tan Valley gets in line with every other community. Becoming a city would give it access to federal funds as well as greater control over what its residents want.

Pinal County Supervisor Mike Goodman represents San Tan Valley.

"Put the government in control of the people and that's what a municipality does," said Mike Goodman, Pinal County Supervisor who represents San Tan Valley. "They get county amenities. But like I said, I'm the only elected official for the County that lives in the San Tan Valley area. This would give more of a local voice to the people and that is one of the reasons why I'm for the incorporation effort."

Goodman says cities are better equipped to build roads and parks and fund fire service than counties.

The group spearheading the effort will still need to convince voters that this is the case.

Later this summer organizers will host a series of open houses to lay out their plan to San Tan Valley residents. They are also meeting with local city governments in Pinal County as well as Mesa and Gilbert to get input and hopefully buy-in on incorporation.

A map of the future city of San Tan Valley still needs to be drawn and the group will need to gather enough signatures in a petition drive before the Board of Supervisors puts the initiative on the November 2024 ballot.

Only residents who will live inside the proposed city limits will vote on incorporating.

PHOENIX - The Phoenix metropolitan area got another taste of the monsoon on Aug. 17, bringing lightning, wind and rain.

Plus, Thursday night's rain is official. The National Weather Service recorded 0.2" of rain at Sky Harbor Airport just before 9 p.m., ending a 147-day streak without measurable rainfall.

The East Valley saw plenty of storm action, with residents in Queen Creek and Mesa reporting hail and high winds.

Monsoon storm recap | Aug. 17

The Phoenix metropolitan area got another taste of the monsoon on Aug. 17, bringing lightning, wind and rain. FOX 10's Anita Roman visits a San Tan Valley neighborhood that was hit particularly hard.

Some residents in San Tan Valley said it felt like a tornado had moved through their community.

"I've never seen the wind come sideways like that…so strong," said Terry, who's lived in the suburb for 18 years. "[I've seen] rain and wind, but never this amount of mass destruction."

Sidewalks were damaged, brick walls were knocked over, and trees were uprooted in one neighborhood near Gantzel Road and Empire Boulevard.

More stormy weather is yet to come as Hurricane Hilary strengthens off the Pacific coast of Mexico. Forecasters are warning that the Category 4 hurricane will impact the southwestern United States with the threat of flash flooding.

The National Weather Service says if Hilary makes landfall in the U.S., it would be the first tropical storm to hit southern California since 1939.

You can check the latest weather conditions by visiting the FOX 10 Phoenix weather page, or download the Free FOX 10 Weather app, which is available on Apple iOS and Android.


The best rain chances across the state will arrive this weekend. The pattern combines a typical monsoon setup, a high pressure "heat dome" to the east and a small area of low pressure to the west, with a tropical system: Hilary.
