GreenWorks provided landscape architecture services, working with Soderstrom Architects of Portland, for Kaiser’s expansion of this regional community hospital facility. This new addition expanded services for Hematology and a number of Oncology services including infusion bays for patients to receive chemotherapy treatments. The project blends the new building into the existing site landscaping, so a thorough review of plant materials and combinations was conducted to make the new and old appear visually consistent. Also, the site’s existing centralized irrigation systems was tapped into, which required working closely with facilities maintenance staff to provide appropriate levels of service without impacting the existing system. The new construction included an increase in impervious surfaces due to new roof area, so the team, including KPFF engineers, created a sophisticated multi-functional amenity to manage stormwater within the landscaping along the edge of the building. This undulating rain garden collects, treats, and detains runoff and was well received as a model for low-impact development in the City of Longview. The garden includes a winding bed of water-loving plants, as well as additional grasses, shrubs and perennials for seasonal interest. It is oriented to enhance the view from within the building, acting as buffer for patients and providing views of nature, while it functions to manage stormwater.
