PINAL COUNTY: Honoring the Past, Embracing the Present,

Envisioning the Future

PAST: FOUNDATIONS OF A COMMUNITY

Established on February 1, 1875, Pinal County was formed from portions of Maricopa and Pima counties in response to the petitions of the upper Gila River Valley. Florence, established in 1866, was designated and has remained the county seat. The county’s early economy was rooted in mining and agriculture, with towns like Florence and Superior emerging as vital centers of commerce and community life. Landmarks such as the Casa Grande Ruins stand as enduring symbols of the region’s rich cultural heritage.

PRESENT: A VIBRANT AND DIVERSE COMMUNITY

Today, Pinal County is a dynamic region characterized by rapid growth and diversity. It hosts a variety of cultural events, including the Arizona Renaissance Festival and Country Thunder, attracting thousands of visitors annually. The county’s economy has expanded beyond its historical roots to include sectors like manufacturing, renewable energy, and technology. Educational institutions and community programs continue to foster a strong sense of community and civic engagement.

FUTURE: STRATEGIC GROWTH AND INNOVATION

Looking ahead, Pinal County is committed to sustainable development and innovation. The county plans to embrace technology to improve performance, collaboration, and public service. Strategic foresight will be utilized to identify potential challenges and opportunities, preparing for various possible futures. Investments in infrastructure, such as improvements to I-10 and the development of Interstate 11, aim to enhance connectivity and support economic growth. Workforce development initiatives, including partnerships with Central Arizona College, are designed to equip residents with skills for emerging industries like aerospace, electric vehicles, and biotechnology.

HISTORY OF PINAL COUNTY

Established in 1875, Pinal County has played a pivotal role in Arizona’s development. From its early days as a mining and agricultural hub to its modern advancements in industry and technology, the county has continued to evolve while preserving its rich heritage.

On February 1, 1875, Pinal County was officially organized out of neighboring Maricopa County and Pima County. This momentous occasion was made possible through a formal petition by residents and was enacted by the Eighth Legislative Assembly of the Territory of Arizona.

As part of this historic milestone, we are proud to showcase the following historical documents.

AK-CHIN:

HIM-DAK ECO-MUSEUM

The Him-Dak Eco-Museum was established to collect, analyze, preserve, protect, promote and teach various aspects of the Ak-Chin heritage, culture and communication between generations. Tribal crafts, exhibits and photographs of the Ak-Chin people are displayed. The museum is distinguished from a traditional museum in that land and territory replace the museum building, and the residents of the area take on the role of curator and public. This museum acts as an exhibit and storage area that reflects both prehistoric and local items from families housed here. It hosts two yearly celebrations: the annual Him-Dak Celebration held in April and the Native American Recognition Day Celebration in September.

APACHE JUNCTION:

APACHE TRAIL

The City of Apache Junction is steeped in a rich history of legends and myths, which adds a touch of mystery and allure to our beloved city. Boasting a rich and vibrant history, there are many reasons the City of Apache Junction has earned its recognition as being “surrounded by legends.”

Apache Junction’s history began with Native American use of the Apache Trail, followed by the 1890s gold rush that established the ghost town of Goldfield, near the legendary Lost Dutchman’s Gold Mine in the Superstition Mountains. The legend of the Lost Dutchman’s Gold Mine has captured the imaginations of treasure hunters and adventurers for over a century, and remains an enduring legend that continues to draw adventurers, treasure seekers, and history enthusiasts to the rugged and remarkable terrain of the Superstition Mountains.

The city itself was named for the “junction” of the Apache Trail with the highway in the 1920s, with its growth accelerating after the completion of the Roosevelt Dam and the development of tourism and retirement communities. Key landmarks like Goldfield, Ghost Town and the Superstition Mountain Museum preserve its Western heritage, while its proximity to the iconic history and landscape continues to draw visitors from all walks of life.

Today, Apache Junction stands as a vibrant community that honors its heritage while welcoming new opportunities and growth. Whether you’re a resident or a visitor, you’ll find the spirit of adventure and discovery alive in every corner. We invite you to be a part of our history, create your own stories, and embark on a journey through time, where the past intertwines with the present, and legends are real.

CASA GRANDE: CASA GRANDE CITY HALL

– FROM OLD MAIN TO CIVIC LANDMARK

Casa Grande City Hall began its life in 1921 as “Old Main,” the city’s first high school, built for $135,000 in the Spanish Colonial style. For 76 years, Casa Grande Union High School has educated generations of students here, making the building a cornerstone of community life.

When the high school relocated in 1997, the city stepped in to preserve and repurpose the landmark. Supported by a Heritage Fund Grant, Casa Grande invested more than $4 million to rehabilitate the building, restoring its historic exterior while creating a modern interior for civic use.

Today, Old Main serves as Casa Grande City Hall, home to the offices of the city manager, city attorney, planning and zoning, and the city clerk. Once a place of learning, it now stands as a center of leadership, service, and civic pride.

COOLIDGE:

CASA GRANDE RUINS

NATIONAL MONUMENT

An Ancestral Sonoran Desert People’s farming community and “Great House” are preserved at Casa Grande Ruins. Whether a gathering place for people or simply a waypoint marker in an extensive system of canals and trading partners, the structures are a large part of the story of this site. Explore the history and stories of an extended network of communities and irrigation canals. Anthropologist and historian Adolph Bandelier visited the Casa Grande ruins in 1883-1884 and reported on its condition and probable significance. The Hemenway Southwestern Archaeological Expedition of 1887-1888, sponsored by Massachusetts philanthropist Mary Hemenway and led by anthropologist Frank H. Cushing, produced further information on the deterioration of the Casa Grande. As a result, several influential Bostonians urged Massachusetts Senator George F. Hoar to present a petition before the U.S. Senate in 1889 requesting that the government take steps to repair and protect the ruins. Repair work began the following year, and in 1892, President Benjamin Harrison set aside one square mile of Arizona Territory surrounding the Casa Grande Ruins as the first prehistoric and cultural reserve established in the United States.

DUDLEYVILLE

Dudleyville is a rural neighborhood in Winkelman. During the 1870s ranchers moved cattle into the lands along the lower San Pedro River. It has small-town charm, and ideal bird watching and hiking due to nearby wildlife from the Lower San Pedro River.

SOUTHERN PACIFIC RAILROAD

The community was named by the Southern Pacific Railroad, which built a switch here in the early 1900s. The name Eloy is derived from the European name meaning the “Chosen” or the “Chosen One”. The Southern Pacific Railroad built the first railroad across Southern Arizona in 1878/1880. It was known as the East Line of Yuma. In 1902 they added a siding and section house six miles west of Picacho and named the siding Eloy, the acronym for the East line of Yuma. During construction of the railroad it was easier, and faster, to handprint E.L.O.Y. on construction drawings and maps, rather than writing out “East Line of Yuma”, each time the railroad made reference to, or revised a drawing.

FLORENCE:

THE HEART OF PINAL COUNTY

Founded in 1866 and named the county seat in 1875, Florence has long stood at the center of Pinal County’s story. Its nationally recognized historic district features one of the largest collections of preserved adobe buildings, Victorian-era storefronts, and the iconic 1891 Pinal County Courthouse – landmarks that reflect the town’s resilience, craftsmanship, and community pride.

Florence is a place where history is embodied. Museums, guided walking tours, and century-old neighborhoods invite visitors to trace the town’s past, while artisan shops, cafés, live music, and signature events bring the town to life. From the internationally known Country Thunder music festival to the Jr. Parada, the nation’s oldest youth rodeo, Florence blends living traditions with contemporary culture in ways that engage every generation.

Situated at the heart of Pinal County, Florence offers a welcoming sense of community alongside modern conveniences, making it a worthy destination to explore and revisit.

GOLD CANYON

Gold Canyon offers stunning views of the Superstition Mountains and is a hub for outdoor recreation like hiking, golf, biking, and camping. Hikers, bikers and campers are always eager to explore its stunning beauty.

KEARNY OASIS IN THE DESERT

The town of Kearny got its start around the same time as a few other towns met their end.

Kearny, which is named after Gen. Stephen Watts Kearny, who passed through the region in 1846 while exploring along the Gila River, was established by the Kennecott Mining Company as the new home for residents of the towns of Ray, Sonora and Barcelona; those three Pinal communities were eventually swallowed up by the company’s expansion of an open pit mine in the area.

Located in what is called the Copper Corridor, an area of central Arizona that has a rich mining history, Kearny sits along the Gila River between the Tortilla and Dipping Springs Mountains.

Mining remains a big part of Kearny’s modern-day economy, as ASARCO operates a large open-pit copper mine near the community.

Today, Kearny is often referred to as an “oasis in the desert” due in part to its proximity to the Gila River and also a recreational lake, with a small park with lake access located within the community. Thanks to its proximity to the Gila River, Kearny is a popular destination for bird watching, fishing and hiking, among other outdoor activities.

KELVIN

Kelvin is home to the historical bridge on the Florence-Kelvin Highway over the Gila River, built in 1916. A modern two-lane bridge was completed in 2018 to replace the original single-lane structure, and the historic bridge was converted into a footbridge serving as a pedestrian-friendly connection for the Arizona Trail.

LA PALMA

La Palma is located near the cities of Eloy and Casa Grande. It’s a small, quiet community with lots of farming. A major feature in the area is the La Palma Correctional Facility, a medium-security prison managed by CoreCivic under contract with the state of Arizona. The name “La Palma” is Spanish for “The Palm”.

MAMMOTH: RUINS

Mammoth was founded around 1872 as Mammoth Camp to serve the nearby Mammoth Mine until 2003, when it closed. Mammoth was incorporated as a town in 1958. The must-see town is nicknamed the “Gateway to the Galiuro Mountains” because it is situated on the banks of the San Pedro River and at the base of the Galiuro Mountains.

MARICOPA: RAILWAYS

Before railroads and highways, Maricopa was home to those who settled around Maricopa Wells. Fed by the Gila, Santa Cruz, Vekol, and Santa Rosa Rivers, the area became a rare and vital desert oasis. In the 1800s, thousands of travelers crossing Arizona to reach California’s gold fields relied on Maricopa Wells for water, supplies, and safety. By the mid-19th century, it had become a key stagecoach stop on the San Antonio and San Diego Mail Line, and later the famous Butterfield Overland Mail Route.

As the railroad era dawned, the town relocated south to form “Maricopaville” in 1879, as a short-lived boomtown built in anticipation of a major rail junction. Though the junction never came, a second relocation just a few miles east solidified Maricopa’s place on the map as a key connection point between the Southern Pacific Railroad and the Maricopa & Phoenix Railroad. For decades, Maricopa thrived as a rail hub—helping to move goods, people, and ideas across the developing West.

Though the town’s prominence as a junction faded in the early 20th century, agriculture took root. Cotton, alfalfa, citrus, melons, and pecans flourished in the desert soil, and cattle ranching became a staple industry. Through it all, Maricopa remained a place of perseverance and community and was officially incorporated in 2003.

QUEEN CREEK: HERITAGE REFLECTS TIES TO THE LAND

QUEEN VALLEY

Queen Creek’s roots lie in agriculture, with citrus, cotton, pecans, and vegetables sustaining families for generations. Early Native communities, homesteaders, and immigrant farmworkers shaped the town’s culture, while traditions of neighborliness, dances, and celebrations created a strong community spirit. Founding families like Ellsworth, Power, Sossaman, Hawes, Combs, and Schnepf left their names on local roads and in town history.

Memories of 4th of July celebrations at the Schnepf farm, train rides on the “dinky,” and community gatherings reflect Queen Creek’s rural heritage. Today, as the town grows, it works to balance development with its small-town charm, preserving open space, trails, and traditions while welcoming new cultural diversity. Incorporated in 1989, Queen Creek remains committed to providing opportunity, recreation, and a high quality of life.

Queen Valley is a unique small community near Superior. In the 1870s, it was recognized as a farming and mining corridor, earning the name the Jewel of the Desert. It sits in a great location, close to the Tonto National Forest and with stunning views of the Superstition Mountains. Outdoor enthusiasts come for hiking, camping and recreational opportunities.

SAN TAN VALLEY: HISTORIC TOWN OF SAN TAN VALLEY’S INCORPORATION

History was made in Pinal County on September 17, 2025, when San Tan Valley officially became Arizona’s newest incorporated municipality and the largest by population in the state’s history.

Nestled in the northeastern portion of Pinal County, San Tan Valley spans approximately 35 square miles, bordered by the San Tan Mountains to the west, Florence to the south, and Queen Creek and Maricopa County to the north. Once a collection of rural communities and master-planned developments, the area has grown rapidly over the past two decades into a vibrant residential hub, representing a blend of small-town charm and suburban growth.

The community’s name honors the San Tan Mountains, whose peaks and trails define the region’s landscape and identity. Efforts to incorporate San Tan Valley had been discussed for years, but it was not until 2025 that residents and community leaders came together to make the vision a reality.

STANFIELD

Stanfield is a small rural, agricultural-based community just west of Casa Grande. Originating from Phoenix, Shamrock Farms moved its entire 10,000-cow herd to a new state-of-the-art farm in Stanfield in 2003. The farm is quite popular for its family-friendly tours.

WINKELMAN:

SMALLEST INCORPORATED TOWN IN ARIZONA

Winkelman is the smallest incorporated town in Arizona, and most of Winkelman’s economic activity is based on copper. The community serves primarily as a service center and residential area for families of employees associated with the mining and processing activities. The principal employer with the Town is the Hayden-Winkelman School District.

FIGURES WHO SHAPED PINAL COUNTY:

As early as 1873, the Weekly Arizona Miner reported that citizens of the Gila River wanted a new county. The western side of the valley was part of Maricopa County and small bit of Yavapai, and the rest was Pima County. A horse could only travel about 20 to 30 miles a day. Phoenix and Tucson, the respective county seats, could be an arduous and dangerous overnight journey to reach. Peter Reignsford Brady, Pima County legislator, took a petition to the eighth territorial legislature with the signatures of Joseph Collingwood, Florence Merchant, Sam B. Wise, an Adamsville farmer specializing in peaches, William Tuttle, a justice of the peace, and Jon B. Divine of Florence and 79 other concerned citizens and taxpayers. The petition cited the vexatious delay, the unavoidable expense of travel, and the great inconvenience of traveling to the respective county seats for the transaction of business. They respectfully asked for a new county to be formed of those portions of the other counties and settlement in the Gila Valley to be called Pinal County. The act to create the county passed on February 1, 1875, and Florence was chosen as the county seat on March 5th.

PINAL COUNTY: Poised for Prosperity

A NEW ERA OF GROWTH AND DEVELOPMENT

As Pinal County celebrates its 150th anniversary, its future has never looked brighter. Once a largely agricultural region, the county has transformed into one of Arizona’s fastest-growing and most economically dynamic areas. With strong population gains, record-setting industrial investment, and a renewed focus on workforce development, Pinal County is emerging as a key player in Arizona’s future.

A POPULATION ON THE RISE

In just over a decade, Pinal County has grown into the third most populous county in Arizona, approaching 500,000 residents as of 2025. This marks a nearly 24% increase since 2010, driven by affordable housing, a strategic location between Phoenix and Tucson, and an expanding job market. Communities such as Casa Grande, Maricopa, Florence, and Apache Junction continue to attract new residents seeking a high quality of life and economic opportunity.

San Tan Valley, the county’s recently incorporated community, now boasts a population of approximately 106,000 residents. Incorporation grants residents more control over local governance, infrastructure planning, and public services—setting the stage for continued growth and community investment.

ECONOMIC INDICATORS SHOW ACCELERATED GROWTH

Pinal County’s economic momentum is outpacing much of Arizona. In 2023 alone, the county’s GDP rose by 9%, nearly three times the statewide average, reaching an estimated $14.3 billion. Per capita income continues to rise, reflecting broader prosperity and job creation across key industries like advanced manufacturing, clean energy, logistics, and mining.

New construction and reinvestment are also reshaping the landscape. In FY 2024–2025, primary property tax valuations increased by over 11%, driven by nearly $190 million in new construction and over $300 million in added value from improvements to existing properties. These numbers underscore both the county’s desirability and its smart planning to accommodate growth.

INDUSTRY INVESTMENT AND INNOVATION

The facility produces luxury EVs that are helping shape the future of clean, hightech mobility — and bringing high-wage jobs and global attention to the region.

COPPER FOR A SUSTAINABLE FUTURE

The Florence Copper Project, now over halfway through construction, will be a vital domestic source of copper—an essential mineral in clean energy, battery storage, and electric vehicles. This project is a model of environmentally responsible mining and economic contribution to the region.

RESOLUTION COPPER MOVES FORWARD

Near Superior, the Resolution Copper project recently advanced past a key legal hurdle, clearing the way for development. Once operational, it could meet up to 25% of U.S. copper demand and contribute billions to the local and national economy. It highlights Pinal County’s growing role in securing America’s clean energy supply chain.

INVESTING IN RENEWABLE ENERGY

Box Canyon Solar Project represents an investment in clean power and local prosperity. By generating renewable energy and returning tax revenue to schools and infrastructure, this project embodies the county’s forward-thinking approach to energy and economic development.

BUILDING THE WORKFORCE OF THE FUTURE

A growing economy requires a skilled and adaptable workforce. Pinal County’s updated Workforce Development Strategic Plan is focused on aligning education, job training, and employer needs to support long-term economic resilience. Partnerships with local school districts, Central Arizona College, and the Pinal County Workforce Development Board are preparing residents for in-demand careers in fields like manufacturing, healthcare, transportation, and information technology.

To help tell the story of its people, assets, and opportunities, the county also launched an updated Economic Development Profile and Visitors Guide—tools that showcase Pinal County as not only a great place to work and do business, but a great place to live and explore.

LOOKING AHEAD

With its ideal location, businessfriendly climate, and commitment to responsible growth, Pinal County is entering its next chapter with confidence. As it honors 150 years of history, the county is equally focused on what’s ahead: a future built on innovation, sustainability, and shared prosperity.

Pinal County is Not Just Growing - It’s Thriving... The Best is Yet to Come.

A MESSAGE FROM YOUR SUPERVISORS

"We will continue to do business as usual, advancing the ball. We really never know what challenges may come before the Board of Supervisors and/or in the three communities that I represent, which are Coolidge, Eloy, and Casa Grande. Something is always going on in all those areas, and if the County can assist each one of those communities, I’m here to help. Water and transportation are two main topics, and I will continue to focus on making some headway."

"I am honored and proud to be a member of the Board of Supervisors in such an auspicious year. This county is growing at an incredible rate. I know that is not a comfort for some residents, however the growth brings remarkable prosperity to the region and much needed services to the residents. I look forward to the bright future of Pinal County and its prominence in the State of Arizona."

“I am honored to take part in this historic celebration marking 150 years since the founding of this great county. My heartfelt thanks to everyone who joined us for the many events held throughout the year in recognition of this remarkable milestone. Here’s to the next 150 years—and beyond—as we continue to build upon Pinal County’s proud legacy.”

THE HON. RICH VITIELLO, PINAL COUNTY SUPERVISOR DISTRICT 1

“As a long-time resident, I have been privileged to not just hear about the tremendous growth of Pinal County, but to experience it first-hand. Many of my children and grandchildren have grown up here, I’ve farmed this land, and went through significant life events in this very community. My decision to run for office stemmed from the desire to get involved and work alongside the great people of Pinal County to help create a brighter future for our families and generations to come. A future where our people can truly live, work and play. I am in awe over everything that has taken place over the years, and feel grateful to witness our community turn into a destination point for residents, developers, and broader industry. My hope is that we continue to grow responsibly and keep our unique identity where families can thrive . ”
