Document Description
The project involves placing a rock riprap revetment wall along approximately 510 linear feet of eroding shoreline. The major compoents of the revetment include an outer armor layer of large rock, which provides protection against wave action, and underlying geotextile and filter stone layers, which supports the armor layer and allow water to pass through the structure while preventing underlying materials from being washed out through the armor layer. The revetment will beplaced parallel to the existing shoreline with the south end transitioning to existing stone shore protection and the north end transitioning to the existing shoreline grade. The revetment design includes a toe-trench that will be excavated parallel to the revetment face and backfilled with 2-3 ton toe stones to prohibit scour below the revetment.
