City of Tacoma – RFB – Foss Shoreline Restoration Outfall 230A Repair Project ES24-0056F – Due 6/4/2024
Due Date: June 4, 11 AM
Pre-Proposal Meeting: A pre-proposal meeting will not be held.
Project Scope: The project Foss Shoreline Restoration Outfall 230A Repair Project will implement erosion maintenance and repair work to the slope cap off the Outfall 230A apron to include excavation, placement and disposal of required slope cap materials and underlying sediments, followed by placement of quarry spall filter, geotextile and heavy loose rip rap sized to prevent further erosion of the slope. A final layer of round streambed cobbles will be placed to fill the void spaces within the heavy loose riprap armoring for habitat enhancement. The extent of the slope cap repair area off the Outfall 230A apron is approximately 180 square
feet and will occur primarily below 0 feet mean lower low water. All repair work will be completed during lowtide conditions but nearly all work will be conducted below the water line from a barge.
Estimate: $131,000
