Design Considerations for Sea-level Rise What will the shore look like in 50 years? 100 years?

How could use of the site change over time as water levels rise?

Are there wetlands or submerged vegetation that will need to migrate inland

over time to survive?

How will shoreline and land use decisions now play out? Will some shoreline

treatments limit options in the future?
