Coastal areas are especially vulnerable to hazards, now and in the future, posed by waves and surges associated with sea level change and coastal storms. Coastal risk reduction can be achieved through a variety of approaches, including natural or nature-based features (e.g., wetlands and dunes), nonstructural interventions (e.g., policies, building codes, and emergency response such as early warning and evacuation plans), and structural interventions (e.g., seawalls and breakwaters). This report discusses the U.S. Army Corps of Engineers' capabilities to help reduce risks to coastal areas and improve resilience to coastal hazards through an integrated planning approach.
The Sacramento-San Joaquin River Delta is the grand confluence of California’s waters, the place where the state’s largest rivers merge in a web of channels—and in a maze of controversy. In 2009, seeking an end to decades of conflict over water, the California Legislature established the Delta Stewardship Council with a mandate to resolve long-standing issues. The first step toward that resolution is the Delta Plan—a comprehensive management plan for California’s Sacramento-San Joaquin Delta, developed to guide state and local agencies to help achieve the co-equal goals of providing a more reliable water supply for California and protecting, restoring, and enhancing the delta's ecosystem.
