the Kuskokwim River Floodproofing and Bank Stabilization EWP Project in McGrath, Alaska.

This IFB is for the McGrath Emergency Watershed Project.  Major items of construction include restoration of the levee and armor bank on the South bank of the Kuskokwim River approximately 1,400 feet downstream from the previously completed bank along Takotna Avenue in McGrath.  The proposed work would lay the vertical eroding bank back at a 2:1 slope, place geocomposite and a layer of bedding material on the shaped bank, then cover the bedding layer with rock riprap.  The bank shaping will extend from the toe of the bank (below OHW) to the existing ground surface in the area.  The riprap blanket will be 2 feet thick above OHW and 3 feet thick below OHW. A stream barb is planned for installation near the downstream end of the riprap revetment. 

May through September of 2013 is anticipated to be the primary constructoin period when work is performed on the eroding river bank and levee. Mobilizatoin is anticipated in summer/fall 2012 and rock riprap bedding producton and hauling is anticipated during winter 2012/2013.
