Title:

Rehabilitate Shoreline & Seawalls / Bluff Stabilization - Phase I

Description:

Project included raising the level of riprap around the shoreline of the bluff, constructing an eight foot wide path around the toe of the bluff, constructing a concrete cell wall at the base of the slope, and regarding the top thirty feet of the bluff. The repairs were concentrated along a section of fluff located along the northwest corner of the unit. The repairs generally included raising he height of approximately 650 feet of the existing riprap revetment along the shoreline of the two rivers; removal of vegetation and loose and unstable soil from the toe and face of the bluff; constructing a 450 foot long low height pre-cast concrete retaining wall at the base of the bluff; and then backfilling behind the wall and against the existing slope with an open graded coarse aggregate to control drainage. The top of the wall was built to elevation 16 feet NVGD. A geotextile was used as a filter media to separate the natural soils from the coarse aggregates. The finished slop behind the wall was maintained at a 2 horizontal to 1 vertical slope. An additional 890 tons of riprap was added to the height of the revetment along the project shoreline and thereby provide additional storm protection to the area. The area between the revetment and the retaining was backfilled and a small path was maintained between the toe of the wall and the riprap revetment for public and park access. The finished slope was covered with a geo-cell geo-textile which was filled with topsoil and seeded.
