Storm surge protection system

A storm surge protection barrier for a shore line bordering a sea that is prone to storm surges, comprising:

• a plurality of individual wall sections each comprising a plurality of plastic-based structural beams joined by at least one cross structural cross tie;
• wherein the plurality of individual wall sections each have an above-grade upper portion of a predetermined first length, LAB and a below-grade lower portion of a predetermined second length LBG, and wherein LAB>2LBG;
• wherein the plurality of individual wall sections are arranged upright and configured to be buried in a trench of the shore line in side-by-side succession to form a continuous barrier wall with the below-grade lower portions disposed in the trench and the above-grade upper portions projecting upwardly out of the trench at a predetermined tilt angle away from the sea of between 1 and 10 degrees;
• metal reinforcements engaging at least some of the wall sections;
• wherein a backside of the barrier wall away from the sea is configured to be supported by an earthen berm extending above grade of the shoreline on which it is installed;
• wherein at least some of the wall sections include pilings configured to be driven into the earth below grade to enhance support of the barrier wall against forces of a storm surge;
• and
• at least one steel cable threaded through the wall sections and pilings to further reinforce the barrier wall.
