Document Description
The Project will place a temporary cofferdam deployed along approximately 55 linear feet (LF) of existing rock revetment at two separate locations for a total of approximately 110 LF of shoreline. Two intake/discharge shoreline structures will be demolished and the material reused for the existing rock revetment adjacent to intake/discharge structures matching the existing material and slope. The work will take place between Mean Lower Low Water (MLLW) and Mean Higher High Water (MHHW) elevations within the footprint of the existing intake/discharge structures. Following the removal of the concrete structures, the shoreline will be replaced with rock revetment placed between Mean Lower Low Water (MLLW) and Mean Higher High Water (MHHW) elevations with matching material and slope to the adjacent rock revetment. All demolished materials not reused will be transported offsite and properly disposed.
