This circular provides United States Army Corps of Engineers (USACE)
guidance for incorporating the direct and indirect physical effects of
projected future sea-level change in managing, planning, engineering,
designing, constructing, operating, and maintaining USACE projects and
systems of projects. Recent climate research by the Intergovernmental
Panel on Climate Change (IPCC) predicts continued or accelerated global
warming for the 21st Century and possibly beyond, which will cause a
continued or accelerated rise in global mean sea-level. Impacts to
coastal and estuarine zones caused by sea-level change must be
considered in all phases of Civil Works programs.
