Where Reunion Begins
Today, Reunion feels like a distinctly modern Colorado neighborhood: welcoming streets, front porches, pocket parks, schools, trails, and families gathering outdoors. Yet its story reaches back much farther than the first home construction. The community sits in Commerce City’s northern range, in an area shaped for generations by open prairie, farming, ranching, waterways, transportation routes, and the steady expansion of the Denver metropolitan region.
Reunion is a master-planned community within the city limits of Commerce City, near the boundary with Brighton and not far from E-470, Tower Road, and the Rocky Mountain Arsenal National Wildlife Refuge. Before houses, playgrounds, and neighborhood streets appeared, much of this land was agricultural and largely undeveloped. Its broad skies and level fields were part of the same eastern-plains landscape that helped sustain the early settlements of Adams County.
That setting remains important to Reunion’s identity. The community was designed not simply as a collection of subdivisions, but as a place intended to connect residential life with Colorado’s agricultural and ranching traditions.
The Older History of Commerce City
To understand Reunion, it helps to understand the larger history of Commerce City. The area is part of the historic homeland of Indigenous peoples, including the Cheyenne, Arapaho, Lakota, Ute, and other tribes who traveled across the Front Range and eastern plains for thousands of years. The South Platte River and nearby waterways provided important routes through the region.
In 1859, John D. “Colonel Jack” Henderson established a ranch, trading post, and hotel on an island in the South Platte River. Henderson Island became an early permanent settlement in the valley and served travelers heading toward the gold fields during the Pike’s Peak Gold Rush. The site is now associated with Adams County Regional Park and Fairgrounds.
During the late nineteenth and early twentieth centuries, the surrounding area developed through farming, dairying, hog raising, railroads, and small settlements. Communities such as Derby, Irondale, and Adams City emerged at different times. One-room schools served rural families, while cemeteries such as Riverside Cemetery, established in 1876, and Rose Hill Cemetery, founded in 1892, became enduring markers of local history.
By the late 1920s, agriculture still dominated the landscape, but industry was beginning to change the region. A refinery was established in 1930, grain elevators appeared during the late 1930s, and the Rocky Mountain Arsenal was founded in 1942. Commerce City incorporated as Commerce Town in 1952 and later became Commerce City after annexations increased its population and geographic reach.
How Reunion Got Its Name
Reunion was created during a major period of planning and growth in northern Commerce City. The city, Shea Homes, and Fulenwider began a broad planning effort around 2000 for approximately 3,000 acres in the northern part of the community. Reunion emerged from that planning process, with the first homes arriving in the early 2000s. Local historical accounts identify Reunion as one of several northern Commerce City communities established around 2002 and 2003.
The name “Reunion” expresses the idea of people and traditions coming together. It also reflects the development’s effort to reconnect new residential life with the agricultural and ranching character of the land. The community’s own history describes Colorado’s farming and ranching heritage as a prominent influence on Reunion’s design.
While Reunion does not represent a nineteenth-century town center or a preserved historic district, its heritage is found in the landscape and in the way the neighborhood was planned. Streets, parks, schools, and gathering places were arranged to encourage a sense of belonging—an especially meaningful goal in a rapidly growing metropolitan area.
The Early 2000s: From Fields to Neighborhood
The first decade of Reunion’s history was one of transformation. In a short period, agricultural land became a network of residential villages, landscaped boulevards, parks, trails, and community facilities. New streets connected the neighborhood to Tower Road, East 104th Avenue, Chambers Road, and regional routes leading toward Brighton, Denver International Airport, and the rest of the Front Range.
The arrival of new residents changed more than the appearance of the land. Families brought schools, youth sports, neighborhood events, local businesses, and civic involvement. Homes were built in a variety of styles, but the common elements—front porches, sidewalks, garages accessed from alleys in some areas, and nearby parks—helped give Reunion a cohesive character.
The neighborhood’s growth took place alongside broader development in Commerce City. Belle Creek was established in 2002, Reunion and Fronterra followed in the early 2000s, and major regional investments such as Quebec Parkway, the new Civic Center, and Dick’s Sporting Goods Park helped place northern Commerce City more prominently on the metropolitan map.
Parks, Schools, and Everyday Landmarks
For many residents, Reunion’s most important landmarks are not grand historic buildings but the places used every day. Pocket parks and neighborhood greens provide the setting for birthday parties, informal soccer games, dog walks, and conversations between neighbors. Heartland Park, Unity Park, and Southlawn Park are among the smaller green spaces associated with the broader Reunion area.
The Reunion Recreation Center and nearby community amenities add another layer to the neighborhood’s identity. Local parks and trails connect residents to a broader Commerce City system that includes hundreds of acres of parks and open space and approximately 25 miles of trails.
Education has also been central to Reunion’s development. The STEAD School, located in Reunion, brings together science, technology, environment, agriculture, and systems design through hands-on learning. Its focus is especially fitting for a neighborhood whose story is rooted in both Colorado’s agricultural past and its future-oriented growth.
Nearby landmarks help place Reunion in the larger history of the city. Dick’s Sporting Goods Park, home of the Colorado Rapids, represents Commerce City’s emergence as a regional destination for sports and entertainment. To the east, the Rocky Mountain Arsenal National Wildlife Refuge offers a reminder that the metropolitan landscape still contains expansive open space and significant ecological history.
A Neighborhood Still Becoming
Unlike older Commerce City neighborhoods, Reunion’s heritage is still being written. Its history does not end with the arrival of the first homeowners. Each new park gathering, school project, neighborhood celebration, and family tradition adds another layer to the community’s story.
What makes Reunion special is the balance between newness and continuity. The streets and houses are relatively young, but the land carries the memory of farms, ranches, waterways, railroads, and wide-open prairie. The neighborhood’s name suggests a coming together, and that remains an apt description: old regional traditions meeting new families, urban growth meeting open land, and carefully planned development meeting the informal warmth of a genuine community.
For longtime residents, Reunion’s appeal is easy to recognize. It is a place where Colorado’s past is not preserved only behind museum glass. Instead, it lives in the open horizon, the agricultural references in the community’s design, the trails and parks, and the everyday connections formed between neighbors. Reunion may be one of Commerce City’s newer neighborhoods, but its sense of place is grounded in a much older Colorado story.
