GreenWorks developed a Stormwater Retrofit Master Plan for the Oregon Zoo at the request of the Portland Bureau of Environmental Services in partnership with the Oregon Zoo. The Oregon Zoo is one of Oregon’s top tourist attractions and is ideally suited for public education related to environmentally-responsible and sustainable site design. Subsequently, GreenWorks was contracted by METRO to implement parking lot and Greenstreet improvements, at this major tourist attraction, to treat and detain surface runoff, provides public education and creates aesthetic improvements. GreenWorks was part of a design / build team to implement strategies that included stormwater filtration for street runoff and flow-through stormwater planters for parking lot runoff treatment. The project was funded by an EPA grant.
