Sea level rise and other flood-related hazards can have potentially severe impacts. NOS helps coastal communities move beyond a “one size fits all” approach when analyzing and planning for these threats. For a start, NOS has been measuring sea level for over 150 years, with tide stations operating on all U.S. coasts. NOS also offers the Coastal Inundation Toolkit, which helps users of any technical skill level understand the causes of inundation, identify local vulnerabilities, and communicate risks. Another helpful tool is the Sea Level Rise and Coastal Flooding Impacts Viewer, which shows how various levels of sea level rise are likely to impact coastal communities.
