The seven-story Watershed Building at 900 N. 34th St. in Seattle’s Fremont neighborhood was designed to meet the stringent requirements of the Living Building Challenge.
The recently completed 72,000-square-foot building is part of a city of Seattle pilot program that offers incentives for meeting requirements or “petals” of the challenge. Stringent energy and water conservation measures are aimed at minimizing a building’s impact on the environment.
Watershed is designed to meet the “materials,” “beauty” and “place” petals. It also meets city requirements for reducing total energy usage by at least 25% and total water usage by 75%, as well as reusing 50% of captured stormwater on site.
The building treats polluted stormwater from Troll Avenue and the Aurora Bridge through a series of stepped bioretention planters. The system will treat over 300,000 gallons of stormwater a year. Another 200,000 gallons of stormwater from the building’s roof will be collected and reused.
The seven-story building has about 60,000 square feet of office space and 5,600 square feet of ground-level retail space. There are 14 parking stalls and secure bike storage for 100 bikes.
