“From the outset Greenbridge sought the input of its community with early design meetings conducted in six different languages to reflect its diverse residents. This inclusive process has resulted in a vibrant, art-filled neighborhood that connects its residents through play, gardening, walkable and bikable streets. This project will change lives,” said Joanna Frank, Executive Director, Center for Active Design.

Upon receiving a HOPE VI grant from the U.S. Department of Housing and Urban Development, the King County Housing Authority commissioned GGLO to develop a plan for the revitalization of an existing affordable housing site in Seattle. Major challenges to revitalizing the site included creating a walkable design that fit within the context of the existing low income, and low-density neighborhood. The resulting Plan focuses on supporting the health and liveability of residents, by increasing connectivity between uses, as well as the amount and type of open space. The plan also uses placemaking to create spaces for community gathering.

Active Design Highlights

  • New and improved pedestrian paths establish a variety of routes, allowing residents to walk within their neighborhood and to nearby retail centers.
  • Open spaces ranging in size were placed across the site and made accessible to people of all ages: community parks, food gardens, and pocket parks are connected by sidewalks, trails, and paths.
  • Recreation spaces were located to create strong relationships with adjacent uses, such as homes, schools, and community centers, increasing safety and accessibility.


  • Placemaking was key: walkability and nodes for community gathering are enriched by commissioned art and the preserved existing trees.
  • A number of regulatory changes were required by King County in order to achieve the desired design outcomes.
  • To engage residents as well as the local Housing Authority in the planning and design process meetings were translated into six different languages.
