Coastal Management

Almost a decade into the 21st century, California's coastal cities continue to face unprecedented population growth and associated development pressures placing demands upon coastal marine ecosystems, water supply and vibrant diverse communities. As the largest urban center on the West Coast and the second largest in the nation, the city of Los Angeles is recognized as a "megacity" and is at the heart of the debate about the effects of urbanization on our coastlines. There are 17 million residents who live in the counties that comprise the Southern California urban watershed – the region served by the University of Southern California (USC) Sea Grant program. With 75% of California's population living within coastal communities it is critical to address the ever-increasing challenges to coastal cities and ecosystems such as sea level rise and other threats from climate change.
