Mike Lydon is a Principal at The Street Plans Collaborative and one of the founders of Tactical Urbanism. It is through his work and his articulation of the work of others that many of us have come to learn about tactical urbanism. He remains on the cutting edge of trying to figure out how short-term experiments can be used to catalyze and create sustainable change. Essentially, he has helped create a new paradigm for community change that is continuing to have significant impacts.
