Cottonwood Pile Dike Repairs

W9127N26BA005 Cottonwood Pile Dike Repairs The project is located between River Mile 68 and River Mile 72 on the Lower Columbia River in Cowlitz County, Washington. The project allows for focused, cost-effective repairs to select sections of individual structures. Repair areas are limited to sections of pile dikes that have experienced loss of all, or the majority of, visible piles to the extent that hydraulic function is assumed to be severely compromised. The work includes enrockment repair/enhancement areas at ten pile dikes and a shore connection with an offset pile dike at five of the pile dikes. The offset pile dikes and shore connection are in areas where there is visual evidence of shoreline erosion and a lack of sufficient remnant shore connection and the potential for additional erosion exists. The enrockment repair/enhancement sections in repair areas are offset a sufficient distance from the existing pile line to allow for placement of stone without removal of any pile. All debris within the rock placement areas that would interfere with stone placement shall be removed prior to stone placement. Debris will be removed from the site and disposed of at an approved upland facility. Debris removal requirements will be based on pre-construction high resolution multi-beam bathymetric survey data.
