Leslie Oberholtzer is a principal and Director of Planning at CodaMetrics, a boutique planning lab in Chicago, Illinois. With over 25 years experience in urban design and smart growth planning, she works to promote sustainable development through the availability of alternative transportation and housing choices, the development of valuable places, and the preservation of community traditions. In addition to being a registered landscape architect and a certified planner, she is National Charrette Institute (NCI) certified and a LEED Associated Professional. Over the past 12 years, Leslie has developed over twenty-five neighborhood and full city codes for communities across the country. Recently, her work has focused on the research and development of form-based codes for Transit Oriented Development (TOD) nodes, corridors, and neighborhoods. Sustainability is at the core of the work Leslie produces not only through a focus on walkable and transit-served places, but also through the development of alternative energy, conservation area, and tree preservation ordinances. She also currently serves on the Location and Planning Technical Advisory Group for the US Green Building Council and the Star Community Index Technical Advisory Group, both cutting edge tools for sustainability at all scales of community.
