Alternatives for Coastal Development: One Site, Three Scenarios
Why Develop Alternatives?
Changes Over TimeThe need for coastal communities to consider a variety of development scenarios is only going to increase as coastal population densities continue to grow. Currently, more than half of the United States' population lives in the 640 counties covering the areas in which major rivers and streams flow into the oceans and Great Lakes. Between 1970 and 2000, population increases to the finite land area of those counties increased their overall population density from 123 to 167 people per square mile. Nearer to the shore, population densities are higher. In areas adjacent to the coast, the population density is over 230 persons per square mile – three times that of the nation as a whole. (Colgan 2003) This project's coastal study site, Camden County, Georgia, experienced a 44.7 percent population increase from 1990 to 2000, and Georgia is not alone (U.S. Census Bureau 2003). Today, almost one-half of the nation's new construction occurs in coastal areas, and over the next 15 years, coastal populations are expected to increase by approximately 27 million people (Pew Commission 2002). Land use trends of coastal Georgia shown in the interactive time series of satellite images below display vegetated lands successively converted to development. National statistics indicate that a time series of satellite images for your coastal area would likely tell a similar story. View the Changes
