Cities along a major water’s edge are well know for their economy, diversity and urban culture. These regions are highly defined by their relationship with the coast, are highly desirable places to live and are generally very densely developed. While these region’s growth and status as economic centers are continually ascending, real threats to this status are posed by the impacts of climate change. Among the many expected climate change impacts, perhaps the largest of all the threats is rising sea levels resulting in the widespread inundation of existing urban development along the shoreline. With so much at stake, how can these jurisdictions evaluate, adapt to, and integrate new boundaries while maintaining existing development, economy, and most importantly: community?
