By 2020, North Carolina's population will increase by two million, with much of the growth predicted to occur in the coastal counties. How well cities and counties handle this growth will depend on how well they plan for it. A number of development approaches exist -- sustainable development, smart growth, new urbanism, and mixed-growth. All plans stress balancing environmental and economic goals while at the same time creating livable communities. Smith discusses two new environmentally friendly building projects. River Dunes is a 1,300-acre pine plantation in Pamlico County that is being turned into a residential and boating community. The other describes how individual home owners can build a green and clean house of their dreams.
