Document Description
NOTE: Review Per Lead The DPW proposes to repair portions of the Channel. The Channel requires repairs to correct damage from erosion that impede proper flood control. Approx. 8,150 ft of the Channel would be repaired as part of the proposed project. The proposed project is a short-term construction project that would not result in any operational changes to the flood control of the Channel. The project components include (1) weir reconstruction; (2) channel wall spall repair; (3) channel invert spot repair; (4) levee panel reconstruction; and (5) channel repair and replacement. The concrete finish of all repairs would match the existing finish of the Channel.
