GreenWorks, as a subconsultant, developed a planting design for a 9-acre wetland treatment system, in collaboration with CH2M Hill and Bob Knight, Ph.D for the Willow Lake Wastewater Treatment Facility. GreenWorks also co-led an effort to work with public interests, to plan and design non-process related facilities, including public access; trails; interpretive facilities/signage; site buffers; and public parking.
