A sea wall system incorporated into a continuous and foundation supported structure, including a plurality of panels which are displaced in either of vertical or horizontal fashion from interior locations associated with the foundation structure. The panels are each constructed of a lightweight and fluid resistant material and are each displaceable from a first retracted position to an extended position, whereby the components collectively establish a heightened water barrier. A fluid communicating opening is defined in the foundation support and, in response to a rising water level, vertically displaces the panels.
