Interstate Maintenance Facility Renovation

Portland Water Bureau

Portland, Oregon

Client: MWA Architects

Building Size: 71,000 sf

Project Cost: $50 million

Certifications: LEED Gold

The City’s 90-year-old Maintenance Building was replaced with a new highly efficient facility to meet the Water Bureau’s current Operation and Maintenance programs. The new facility incorporates the most current energy design criteria, substantially more economical to operate, and heavily reinforced to ensure the concrete and steel structures would survive an earthquake intact while still serving as a hub for Water Bureau crews.

The project incorporated numerous sustainable design features, including a solar-heated water system, solar electricity and an eco-roof. The visitor parking lot uses impervious concrete, and all stormwater runoff is managed on site through a series of bioswales.
