909 Walnut is the expression of a developer’s dream—turning a landmark 36-story art deco office building into the tallest mixed-use apartment building in the state of Missouri. The developer had a vision of providing a “green roof” atop an adjoining 8-story parking garage to serve the residents of the building in a downtown area lacking green space. As prime consultant, Jeffrey L. Bruce & Company provided design and construction administration services for the green roof on the parking deck.
Envisioned as a secluded retreat for residents, JBC incorporated many green technologies to solve the inherent challenges of constructing green roof projects in urban conditions. Special soil profiles were specifically designed to meet the diverse needs of this demanding site. The project required considerable agronomic innovation to ensure sustainability of the landscape under heavy daily use by residents and pets. The 909 Walnut green roof has become an icon of Kansas City—frequently seen on banquet invitations, professional model shoots, and educational sessions that are fueling an explosion of green roof construction in the region.
