San Francisco Bay Scenarios for Sea Level Rise Index Map

BCDC used data from the United States Geological Survey (USGS) to produce a series of sea level rise maps showing areas vulnerable to 16 inches of sea level rise at mid-century and 55 inches at the end of the century.

BCDC has produced a three-map series to illustrate two sea level rise scenarios. The series depicts:

• a mid-century sea level rise of 16 inches;
• an end of century sea level rise of 55 inches; and
• a composite of both 16 and 55 inches.
