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.  The Chapter founders are Wolf-Lyon Architects and Van Meter Williams Pollack LLP.
