​North Transfer Station
Seattle, Washington
Client: City of Seattle
Partner: ​Camp, Dresser, & McKee

Seattle Public Utilities is replacing the current North Transfer Station with a more modern and efficient facility. Parametrix provided site civil design and permitting for the demolition of the existing station and design of the replacement transfer station. We modeled vehicle movements including all transfer trucks and trailers beneath the tipping floor of the building. The facility will have a combination of concrete pavement in locations of commercial vehicle traffic and asphalt pavement in public vehicle areas to reduce surfacing costs.
