1 Shown is the central range (middle 67%) of values from model-based probabilities rounded to the nearest inch.2 The rapid ice melt scenario is based on acceleration of recent rates of ice melt in the Greenland and West
Antarctic Ice sheets and paleoclimate studies.

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?
