3. PROJECT BACKGROUND & DESCRIPTION

The USACE Charleston District has a coastal storm risk management project within the Charleston Peninsula, South Carolina consisting of a storm surge structure approximately 8.7 miles in length with a top elevation of 12 feet NAVD88, multiple pedestrian, vehicle, railroad, and storm (tidal flow) gates, approximately five temporary and five permanent small to medium hydraulic pump stations, approximately 9,300 feet of oyster reef-based living shoreline sills, floodproofing or elevating approximately 100 structures in residential areas where construction of the storm surge structure would be impracticable, and mitigation for natural, cultural, historic, and aesthetic resources, as generally described in the Charleston Peninsula, South Carolina, Coastal Storm Risk Management Study Final Feasibility Report / Environmental Impact Statement.

This A-E SATOC is to provide Design Services which may include, and are not limited to, performance of all activities related to detailed Pre-Construction Engineering and Design (PED), up through preparation of plans and specifications for the initial construction contract, and request for proposal for Design Build phases for the Project.

Hydrodynamic and Hydraulic Modeling: Simulation of storm surge, tidal influences, and wave heights to design for maximum surge and wave impact.

Environmental Impact Assessment (EIA): To comply with NEPA (National Environmental Policy Act) or other local environmental regulations, assessing the impacts on ecosystems, water quality, etc.

B. Detailed Design Engineering Flood Protection System Design: Design of the storm surge barrier, considering factors such as height, thickness, materials, and reinforcement to withstand extreme conditions. Integration with the surrounding landscape, including access roads, drainage systems, and utilities.

Flood Protection Components: Detailed design of flood gates, barriers, pumping stations, and tide gates that could work in conjunction with the surge wall.

Natural Features: Detailed analysis and design of natural features for storm surge protection and mitigation features.

C. Environmental and Regulatory Design Compliance Permitting and Approvals: Work to obtain all required permits (e.g. Army Corps of

Engineers, local agencies, etc.).

Environmental Mitigation: Design to minimize environmental damage, with plans for habitat restoration or other mitigative actions.

D. Risk Management Risk Analysis: Conduct a thorough risk assessment, particularly with regard to potential failure modes of the surge wall during extreme weather.

E. Operations and Maintenance Plan

Maintenance Guidelines: Provide clear guidelines for the maintenance and inspection of the wall, including recommendations for preventive measures.

Operations Plan: Provide an O&M plan for gate structures and pump stations

F. Construction Phase Support RFI and Shop Drawing Reviews
