Public spaces, like sidewalks, parks, and trails, are supposed to be a city’s most equitable areas, says John Slack. Slack incorporates that lens of equity into his design work, so that “when the designers are gone, the community can move forward and implement the space.” The Minneapolis studio of architecture firm Perkins&Will is overseeing the Upper Harbor Terminal waterfront park project, aimed at reconnecting North Minneapolis residents with the river after decades of being cut off after I-94 was built. Wrapping up next summer, the project, built on a foundation of more than four years of community engagement, will be a “regeneration.”
