Lee has been involved in plan implementation through zoning in a variety of settings over the past 30 years. His emphasis has been on redevelopment activity in urban areas throughout the United States. Lee sharpened his skills in the preparation of plans and zoning across the country, and has been personally responsible for over 50 code projects, including the complete revision and adoption of over 30 conventional codes and 20 form-based codes. His combination of conventional zoning know-how and new code approaches are rare in the profession, and his ability to facilitate the consideration and adoption of new zoning serves his clients well.
Lee served as an adjunct faculty member in the Department of Community & Regional Planning at the University of Texas. Lee is a frequent conference speaker on zoning, form-based codes and charrettes, including a 2016 two-week speaking tour across Australia on behalf of PIA.
