Concrete Couch, our local community-building art and sustainability nonprofit, devotes its many talented volunteers and staff to beautifying, diversifying and sustaining our communities — and they recruit members of those communities, too, ensuring that development happens from the inside out. Having built projects from mosaics (like the one at Penrose Library) to playgrounds (at the former Helen Hunt Elementary School), they've proven their commitment to making our city a better place. But even these superstars aren't shy about learning from the experts. Today, they bring in Mark Lakeman, co-founder of the City Repair Project in Portland, Oregon, who has contributed to more than 300 permacultural or architectural designs in Portland alone, plus a whole host of projects across the U.S. and Canada. Lakeman will focus his presentation on permaculture, architecture and healthy communities, and there will be plenty of time for questions for curious community-builders. A few of Lakeman's most renowned and successful projects have included Dignity Village and Kenton Women's Village, creative and self-sustainable homeless communities, meaning he has just the insight we need to continue working toward long-reaching, empathetic solutions to the growing homeless crisis in our city.
