A Neighborhood with Deep Roots
Today, Knoch Knolls is known for its gracious homes, winding streets, mature trees, and easy access to trails along the DuPage River. The neighborhood sits in south Naperville, near Knoch Knolls Road, 95th Street, and Plainfield-Naperville Road, yet it feels pleasantly removed from the bustle of the surrounding suburbs.
That sense of retreat is not accidental. Long before the subdivision’s homes were built, this was a landscape defined by riverbanks, wooded groves, open farmland, and the meeting of the East and West Branches of the DuPage River. The neighborhood’s history is a story of how Naperville grew while still preserving pieces of the countryside that came before it.
Why It Is Called Knoch Knolls
The name comes from the Knoch family, longtime owners of a large farm in the area. Judge Win Knoch and his wife, Irene Knoch, were prominent members of the Naperville community, and their property became associated with the rolling land along the river. The Knochs themselves referred to their farm as “Knoch Knolls,” a name that eventually became attached to both the park and the residential neighborhood.
The name also reflects the land’s character. Even in a relatively flat part of the western suburbs, the river confluence creates gentle rises, wooded slopes, and changing views. Driving along Knoch Knolls Road, it is easy to understand why the word “knolls” endured.
The Knoch family’s connection to the area went beyond naming rights. On March 24, 1980, Win and Irene Knoch donated 13 acres of farmland to the Naperville Park District for public park purposes. The Park District later purchased the remainder of the Knoch farmland, creating the foundation of today’s Knoch Knolls Park.
Before the Subdivision: The River Confluence
The land around Knoch Knolls has a much older history than its late-twentieth-century homes suggest. The confluence of the DuPage River branches made the area attractive to people for generations, providing water, transportation routes, wildlife, and fertile ground.
One of the earliest documented European settlers connected with the site was Stephen Scott, who established a homestead south of the West Branch of the DuPage River in 1830. Scott built a log cabin and operated a water-powered sawmill, turning local timber into lumber for houses and barns. His settlement predates Captain Joseph Naper’s arrival and the founding of the community that became Naperville.
The original mill disappeared long ago, reportedly washed away during a season of high water. Near the entrance to Knoch Knolls Nature Center, however, visitors can see *Reflections on Scott’s Mill*, a rustic artistic recreation that recalls this early chapter. It is not an original building, but it provides a tangible reminder that the park’s trails pass through one of the earliest settlement landscapes in the region.
The Park Takes Shape
The creation of Knoch Knolls Park was one of the most important milestones in the area’s modern history. After receiving the Knochs’ 13 acres in 1980, the Park District used a Land and Water Conservation Fund grant to purchase the remaining farmland. In 1988, the District added Glyman Woods, a 55.8-acre wooded tract to the east. The Biannucci Confluence was added in 1989, bringing the park to approximately 218 acres.
Those acquisitions helped ensure that the river corridor would not be completely transformed by development. Instead, residents would have access to woods, ponds, wetlands, open meadows, and river overlooks. The park became a defining neighbor to the subdivision and a lasting example of Naperville’s investment in open space.
The park’s amenities have expanded over time:
- Hiking and biking trails wind through woods and along the river.
- A canoe and kayak launch provides access to the DuPage River.
- Fishing areas and ponds offer quieter forms of recreation.
- Playgrounds and picnic shelters make the park a gathering place for families.
- The disc golf course, expanded to 18 holes in 2015, adds another popular activity.
- The Frank Rus Preserve protects nearly 40 acres of wooded land on the park’s west side.
The Residential Neighborhood Emerges
Knoch Knolls subdivision developed during the late 1980s and early 1990s, a period when Naperville was growing rapidly south of 75th Street. City planning documents identify Knoch Knolls among the major low-density residential developments that emerged in south Naperville during this era. The subdivision’s original covenants for Units I and II were recorded in October 1987, placing the neighborhood’s formal beginnings within that broader period of expansion.
The neighborhood was designed around spacious lots, traditional single-family homes, and a setting that preserved much of the area’s rural feel. Streets such as Knoch Knolls Boulevard and the adjoining residential drives curve through the community rather than forming a rigid grid. Mature trees, generous setbacks, and views toward the park help distinguish Knoch Knolls from newer subdivisions built more tightly around cul-de-sacs and engineered ponds.
The neighborhood’s location also shaped its identity. It is close to downtown Naperville, yet it is separated from the center of town by the river corridor and parkland. Nearby McDonald Farm, operated by The Conservation Foundation, adds another preserved landscape just beyond the homes. Together, the park, river, and farm create a green framework that has remained central to the neighborhood’s appeal.
The Nature Center and a New Chapter
A major modern milestone came with the opening of Knoch Knolls Nature Center in 2014. The center was built in response to community interest in environmental education and provides exhibits, programs, and a gathering place for learning about the prairie, woodland, wetland, and river habitats found in the park.
The Nature Center also helps connect the area’s natural history with its human history. Interpretive displays discuss the people who lived near the confluence, the early settlements that followed, and the ways the river shaped Naperville’s development. In 2024, the center marked its tenth anniversary, underscoring how quickly it has become one of the neighborhood’s signature institutions.
For longtime residents, the center is more than an educational building. It is a place where school groups, families, walkers, and nature enthusiasts meet. In spring, the woodland trails are especially memorable when Virginia bluebells and other native plants brighten the forest floor.
A Heritage That Continues to Evolve
Knoch Knolls has changed considerably since the days when the Knoch family farmed the land. Fields became homes, farm lanes became neighborhood streets, and former working land became one of Naperville’s most valued park systems. Yet the area has avoided losing its sense of place.
Its heritage survives in layers: the memory of Stephen Scott’s cabin and mill, the Knoch family’s generosity, the preserved river confluence, the wooded Glyman Woods, the Frank Rus Preserve, and the homes that took shape during Naperville’s great suburban growth.
That combination is what makes Knoch Knolls special. It is not simply a subdivision beside a park. It is a neighborhood whose identity was built around the landscape itself. A walk from Knoch Knolls Boulevard to Knoch Knolls Nature Center, or along the trails toward the DuPage River, still offers a glimpse of several Napervilles at once: the frontier settlement, the farm community, the conservation-minded city, and the welcoming residential town that exists today.
