Redmond Wetlands Complex

City of Redmond has grown substantially since its conventional wastewater treatment plant was last expanded in 2000. Seeking to accommodate increased wastewater treatment needs in a sustainable manner, the mechanical system will be replaced by a new system of constructed water treatment wetlands that will provide treatment that is safe for people, wildlife, the land, and water. Walker Macy is part of a team currently designing the Redmond Wetlands Complex, with an emphasis on public open space and amenities as a community co-benefit to the facility engineering. Located just north of the city, the site has phenomenal views of the mountains and will be a great place for residents to walk the trails and enjoy the wildlife. The project provides a recreational trail system integrated with a water treatment system that requires lagoons, treatment wetlands, and disposal wetlands. The open space design includes a series of trails, trailheads, boardwalks, and overlooks, a large picnic and gathering area with demonstration gardens of low water use landscaping, and multiple spaces for people to sit, rest, and enjoy the views.
