About Us

The Congress for the New Urbanism, CNU, views disinvestment in central cities, the spread of placeless sprawl, increasing separation by race and income, environmental deterioration, loss of agricultural lands and wilderness, and the erosion of society’s built heritage as one interrelated community-building challenge.  In response, CNU promotes walkable, mixed-use neighborhood development as an environmentally, socially and economically responsible solution to the challenges of community building. CNU engages our multidisciplinary members in reforming industry practice.  Read the Charter of the New Urbanism

CNU Colorado is the statewide chapter of CNU.  Since 2009, we’ve been dedicated to sharing and growing our intellectual capital, provoking ideas & discussion, and celebrating urbanism in Colorado.

Gregory Leichty, PLA

He brings a broad knowledge-base and almost a decade of experience designing and implementing landscapes to the projects that he works on. He has developed an affinity for problem-solving, which he uses to bring unique solutions to landscape and urban design projects. Greg has played an integral role in the design and construction administration for the Port Lands Flood Protection project in Toronto, Ontario.

Greg was drawn to the principals of New Urbanism early in his career, and finds the framework to be an effective tool to understand and communicate the benefits of building complete neighborhoods and cities connected with safe, multi-modal transportation. Greg firmly believes that great cities are our best tool in the effort to mitigate the effects of climate change, improve quality of life and health, among numerous other benefits compared to the status-quo. In addition, Greg is driven to help create great cities to help reduce development pressures on our wild landscapes and agricultural lands to preserve those landscapes for the benefit of future generations.
