Blue Dunes: Climate Change by Design is a book documenting the proposal to create an offshore barrier island chain in the New York/New Jersey Harbor. Today, this proposal stands at a crossroads and its potential for the future of coastal protection requires further development. Participating scientists, engineers, planners, economists, and maritime stakeholders identified critical key issues including: water quality, habitats, recreation, navigation, constructability, and funding. The Blue Dunes Research Initiative (BDRI) explored these issues and developed a new approach to coastal protection. Funded originally by HUD and the Rockefeller Foundation through the Rebuild by Design competition, the work behind this book describes the necessity of creating a knowledge network around resiliency for the entire region’s urban coastal communities; from the organizations that serve them to the scientists invested in researching them.
