As Project Manager and lead designer for Rana Creek and now as a consultant for Rana Creek, Marie designed 25,000 sf of native meadows and a 90,000 gallon water reuse system for the rooftop gardens at CPMC Cathedral Hill Hospital (CHH) in San Francisco. The project also included interior gardens designed to symbolize the lost native landscape of San Francisco. Over a ten year period, Marie worked as part of an Integrated Project Delivery Team (IPDT) consisting of engineers, architects, and health care professionals to develop options for healing rooftop gardens for the patients, visitors and employees at CHH. Using the Choosing By Advantages approach to decision making, the designs for the gardens and the water reuse system took on many iterations before ultimately becoming very simple, native grasslands planted in 6” of soil. The project is in the finishing stages of construction.
