North Seattle College Opportunity Center for Employment and Education

The design for the college’s Opportunity Center reimagined an existing classroom building, adding and renovating it to create this three-story, LEED Gold administration building with a 7,000-ft² green roof. MKA’s civil site design introduced stormwater planters that detain building runoff and reduce site detention pipe sizes by more than 50%. A hybrid stormwater planting strip/bioretention cell system in the south parking lot provides decentralized detention and water quality treatment while maintaining the required parking stall quantity and creating a natural drainage course to convey treated water from the south parking lot to the storm drainage system.
