The City of Gresham is located east of Portland, Oregon, and is the fourth largest city in the state. Gresham government and community are continually working together implementing programs recognized for their innovative leadership in sustainable practices.
A hallmark of a sustainable project is the ability to reduce impact on the environment by lowering the quantity of needed new materials or reducing the need to eliminate existing materials. With this in mind, when the City required additional space for office and educational purposes at their wastewater treatment facility, they looked to their first structure used to treat wastewater; a mothballed 1950s era primary digester building. After an initial evaluation to determine the cost, benefit, and possibility of rehabilitating the building for new uses, the City decided to transform the outdated, yet sound, process building into an environmental interpretive and personnel training center, administrative offices, and secure City archives facility.
