VIDEO: Buffalo CDF Scheme

The U.S. Army Corps of Engineers, Buffalo District, has just released a video about the ‎Buffalo confined disposal facility dike (‎CDF) #4 repair project.

This repair scheme consists of moving the large stones at the dike crest and placing them down-slope to fill voids.

Smaller stones are being placed at the crest and also fill voids created by wave action and grouted to help lock everything together, creating a solid base to install cast-in-place concrete blocks at the dike crest.

New large stones will be placed against the cast-in-place blocks for greater structural integrity.

The work began in August, 2015 and is scheduled to continue through the end of the 2016 construction season.

The CDF is located at the south end of the Buffalo Harbor and was constructed in 1977 by building a stone perimeter dike from the Lake Erie shoreline, south of the Buffalo Harbor South entrance, to the lakeward end of the South Entrance Arm Breakwater and is used to contained legacy dredged sediment.
