The work consists principally of providing bonds, plant, labor, materials, equipment, and supervision necessary to furnish and perform the Blakeley/Mud Lakes Confined Disposal Facility (CDF) Dike Raising. The CDF encompasses approximately 220 acres and is generally rectangular in shape with a north-south dimension of 3,500 feet and an east-west dimension of 2,900 feet. The CDF has an exterior perimeter dike approximately 13,000 feet long and is separated into a 100-acre East Cell with a dike 6,700 feet long and a 120-acre West Cell with a dike 6,200 feet long. An interior north-south dike 3,500 feet long separates the two cells. For this project the East Cell dikes and interior northsouth dike are designated as the East Cell. The West Cell is defined by the three sides not including the interior north-south dike. The stationing is numbered to reflect these designations. The top of the dike elevations for the east dikes and interior dike have recently been raised to an elevation approximately 58 ft North American Vertical Datum of 1988 (NAVD88). A project has been recently completed to raise the west dikes to elevation 54 ft NAVD88.
