O'Day Park, located in the heart of St. Charles County, Missouri, is a shining example of the balance between suburban development and the preservation of natural landscapes. As suburban sprawl gives way to the open rural countryside, O'Day Park offers a serene escape while providing a host of modern amenities and attractions.

An Immersive Vision
At the core of the park's mission was the client's vision to honor and highlight the natural character of the site while fostering environmental stewardship. The park's design focuses not only on the user experience but also on the preservation and enhancement of the surrounding habitat. This dual-purpose approach is seen throughout the park's layout, from the adventure playground that weaves through the natural landscape to the miles of paved and natural trails that guide visitors on a journey through the site's rolling topography. Whether guests are walking the trails, enjoying a live performance in the outdoor amphitheater, or attending an event in the conference center, the park aims to immerse them in a space that encourages exploration, relaxation, and interaction with nature.

 

Playground of Dreams
The adventure playground, located in the southwest portion of O'Day Park, is one of the most distinctive features of the entire project and has been highlighted as one of the most unique and experiential playgrounds in the St. Louis region. Designed with discovery and accessibility in mind, the playground features winding, ADA-accessible paths that lead users of all abilities through a variety of play elements. These paths invite visitors to explore the different sections of the playground, each of which is designed to stimulate physical activity, creativity, and imagination.

Combining Nature and Play
One of the standout elements of the playground is the interactive water feature, which flows in harmony with the site's natural topography. The water cascades over stone steppers made of native Missouri limestone, creating both a sensory and visual experience that echoes the park's commitment to natural materials and sustainable design. Beyond its aesthetic and play value, the water feature is also a key part of the park's sustainable infrastructure. The water used in the feature is captured and recirculated into a holding tank, where it is reused for irrigation throughout the park. This closed-loop system helps reduce water waste and reinforces the park's dedication to ecological responsibility.
Process
St. Louis-based landscape architecture firm SWT Design played a central role in the creation of O'Day Park, serving as the prime consultant for both the 2013 Park Master Plan and the subsequent design and implementation phases. As the lead firm, SWT Design guided the design process from initial concept development through construction, coordinating with a multidisciplinary team comprising experts in architecture, civil engineering, MEP (mechanical, electrical, and plumbing), structural engineering, and water feature design. This collaborative approach with the City of O'Fallon Parks and Recreation staff and design team members ensured the park would be both functional and cohesive, integrating diverse elements into a unified vision. Throughout the project, SWT Design's work was focused on achieving seamless integration of the built environment and the natural landscape.
Regional Impact
The success of O'Day Park has been recognized by several prestigious awards within the landscape architecture community. In 2020, the park received a Merit Award from the St. Louis Chapter of the American Society of Landscape Architects (ASLA). The following year, it was honored with a Merit Award from the Central States ASLA, further solidifying its reputation as a model for innovative and sustainable park design.
O'Day Park is more than just a public space; it is a celebration of the natural environment and a testament to the power of thoughtful design. By prioritizing sustainability, accessibility, and user experience, the park serves as a vital resource for the O'Fallon community and beyond, offering a place where people can connect with both nature and each other in meaningful ways.
