The 58-story condominium tower planned at 3rd and Cherry received a determination of non-significance (DNS) under the State Environmental Policy Act (SEPA). This finding means site plans do not demonstrate a significant negative impact on the environment, which important for the progress of a site’s development. Rushing is providing mechanical, electrical and plumbing engineering as well as energy services and lighting design for the tower.

With 423 condominiums, eight levels of parking, ground floor retail, rooftop amenities, and a 27,000 square foot public plaza in the works, this site will become a significant part of Seattle’s downtown corridor. The 3rd and Cherry project will span a full block diagonal to the Columbia Center—currently, Seattle’s tallest building—in the old Civic Square which has been vacant since that demolition of the Public Safety Building in 2005.

Bosa Development is developing the property, designed by Joseph Wong Design Associates. As part of Bosa’s contract to develop the site, they will contribute $5.7 million to the city’s affordable housing fund.

Rushing is also part of Bosa’s One88 project team, which completed the 21-story condominium tower in Bellevue earlier this year. Rushing provided electrical engineering, energy services and lighting design.
