Guthrie Green: A High-Performance Park Powering a Renewed Urban District
Tulsa, OK
SWA Group
Lead Landscape Architect: John L. Wong
SWA Group Team: Elizabeth Shreeve, Sergio Lima, Rick Story
Client: George Kaiser Family Foundation

Grand Opening Celebration: Guthrie Green brings together community members, non-profits and performing arts groups—including this concert by the Tulsa Youth Symphony on opening day—to enrich and enliven Tulsa's urban scene.
Park Pavilion Energy Generation: Photovoltaic arrays on the park’s northern pavilion supply a steady source of renewable electrical energy to power the pumping system for the ground source heat pump system. The 11,000-square foot pavilion occupies the location of the former truck and houses a cafe, restrooms, and all-weather, multi-functional space for community events and activities.
Bio-Swales and Elevated Walks: Bio-swales along the east and west portions of the park treat storm water runoff and filter contaminants while recharging groundwater sources. Walkways above the bio-swales allow visitors easy access to the central green beyond.
Rectilinear Paths and Plantings: The park’s grid layout of gardens, paths and fountains reflects the pattern of the geo-exchange wellfield hidden below the surface.
Water Fountains: Fountains within the western gardens, each carved from a block of black granite, express the seeping, misting and jetting characteristics of water.
Eastern Gardens and Splash Fountain: A favorite among kids, the eastern splash fountain provides a welcome respite from Tulsa's warm climate. Adjacent plantings and bioswale enhance the visual richness of the park.
Bocce in the Park: Guthrie Green provides an "outdoor living room" where residents, workers and tourists can enjoy activities and quiet time. The central lawn slopes gently toward the stage, accommodating informal audience seating and free play.
Transition from Street to Park: A vine trellis runs along the park’s Brady Street promenade along the south edge, linking the center stage and the two-story corner “green rooms”. The promenade provides overflow space, and Brady Street can be blocked off for major gatherings and events.
Guthrie Green View Towards Pavilion: Seen here from a similar perspective, the completed park now forms the center of the district and has spurred investment in surrounding properties, demonstrating the ability of city parks to power the revitalization of neglected urban districts. Over the last three years, a total of $113.5 million has been invested through a combination of public-private sources including an ARRA Stimulus grant to support the park's geo-exchange system.
Site View before Construction: As part of a district-wide urban design, the landscape architects helped to identify the project site—a former truck loading facility—as an ideal location for a new urban park at the heart of downtown Tulsa's emerging Brady Arts District.
Geothermal Well Field: The ground source heat pump "geo-exchange" system consists of 120 wells drilled to a depth of 500 feet. The system generates approximately 600 tons (7.2 million BTU/hour) of heating and cooling distributed via underground pipes to a restored historic warehouse leased to arts-related non-profit groups.
Guthrie Green Illustrative Plan: Tulsa’s new Guthrie Green provides a place for Tulsa’s residents, workers and visitors to enjoy a central green outdoor space in the midst of a formerly blighted urban industrial center. Designed for high performance, the 2.6-acre park includes a ground source heat pump system, bioswales, district-wide streetscape with LED lighting, and a multi-purpose lawn.

Guthrie Green transforms a 2.6-acre former truck loading facility into a lively new urban park offering gardens, interactive fountains, a lawn amphitheater, an outdoor stage with vine-covered “green rooms”, and an 11,200-square foot cafe pavilion. Located at the heart of Tulsa’s emerging Brady Arts District, the project uses sustainable practices to inform design and push innovations in energy generation. Supported by public-private funding and ARRA and State Energy grants, the park incorporates a 500-foot deep “geo-exchange” wellfield to provide heating and cooling for non-profit tenants in nearby buildings. Photovoltaic panels on the pavilion roof provide electricity for the geo-exchange pumps, and a new stage supports a robust program of community performances, films, public markets, exercise classes, and exhibits. Guthrie Green provides a model for high-performance landscape, demonstrating the ability of city parks to power the revitalization of neglected urban districts.
