Last week REI submitted designs to the city of Bellevue for its new campus in Bellevue’s Spring District. The outdoor co-op has outgrown its headquarters in Kent and last year announced its plans to develop eight acres in the Spring District, between Highway 520 and Bel-Red Road.

The proposed design, which needs design-review approval from the city, includes 400,000 square feet in three buildings to house offices, a marketplace that would be open to the public and a meeting area/fitness center, according to REI.

The design incorporates the co-op’s goal of tying its campus in with the surrounding community. The proposed campus includes three public pedestrian paths linking nearby transit and residential areas, according to an REI news release. It may also include retailers, coffee shops and other food options.

REI now has more than 1,400 headquarters employees working at five locations in the Puget Sound region, according to the news release.

The co-op on Thursday also said it is putting its existing Kent campus up for sale.

REI’s move to its new headquarters would take place in 2020, if all goes as anticipated.
