In all six instances, the modifications were made using the National Oceanic and Atmospheric Administration's zero-foot sea level rise dataset. These modifications were as follows: Added the Delaware portion of the tidal Nanticoke River up to the mean higher high tidal limit; added a braided channel in the Anacostia River in Washington, D.C., at Kingman Island; widened the Anacostia River in Washington, D.C., at the Washington Navy Yard; shortened the Rappahannock River to the mean higher high tidal limit; shortened the York River to the mean higher high tidal limit; and shortened the Pamunkey River to the mean higher high tidal limit.</p>
