Coastal Preparedness

Informed coastal planning, facilitated by access to reliable decision-making tools, will help protect life, infrastructure, and the environment. DGGS projects that seek to close communication gaps, convert available data into a useful format, and educate the public about coastal processes, are designed to support decision-making and minimize losses due to new or exacerbated hazards in the coastal environment.
