Landside
For the 2100 case, where the estimated storm surge elevation is +16.3 feet, all six structures will need to be raised to an elevation of +17.3 feet minimum. Raising the revetment from elevation +15.8 feet to elevation +17.3 feet and filling the area behind the revetment to an elevation of +17.3 feet and would require an estimated fill of 17,000 cy (Figure 5).

2100 Sea Level Rise Case Costs
Element Replaced/Modified Cost
Breakwater $0
Fishing Pier $0
Navigational Piles $0
Marina $0
Landside $3,600,000
Total $3,600,000
Summary
In summary, the marina and piles, the fishing pier, and the breakwater will require replacement or modification as part of required asset management due to the aging of the materials. The required replacements will be designed to accommodate future sea levels.
The landside will require progressive investments over time to accommodate SLR and climate change.
Utility-related impacts will be discussed by EKI in their report. 41 of 46
