I-5 Collonade Park

Location: Seattle, WA
Owner: Seattle Parks and Recreation

Located in the least expected of places (underneath Interstate 5 in Seattle), the park reconnects two severed neighborhoods and creates community gathering and activity spaces. The design approach focused on reusing “lost space” and utilized recyclable materials. Osborn Consulting, Inc. (OCI) team members applied Crime Prevention Through Environmental Design (CPTED) principles to address homeless encampments and public safety issues. Since the park is noisy, it was programmed and designed for complimentary noisy uses, such as a dog park, a mountain bike challenge course, stairs for running, and bicycle trails that reconnect the adjacent neighborhoods to existing bicycle infrastructure. The project has been presented on CNN news as a unique contribution as creative ways to reuse forgotten urban open spaces.
