• State (Cal-Fed Independent Science Board)

• 20”- 55” (0.5 to 1.4m) by 2100 for short-mid range planning
• Minimize damage and loss of life for low-probability events
• Augment with adaptation strategies for higher SLR rates

• Regional (BCDC and CSCC)

• Build now for 16” SLR by 2050
• Incorporate adaptation strategy for 55” by 2100 into project plans
• Include financing mechanism to pay for adaptations

• Federal (Army Corps)

• Multi-scenario planning for 20, 40, 60in SLR
• local agency to select level of acceptable risk

Notes:

Bay Conservation and Development Commission (BCDC) in a recently released studyiv is recommending that Bayfront developments consider a 16-inch SLR value by 2050 (mid-term) and a 55-inch SLR value by 2100 (long-term). The California State Coastal Conservancy (SCC) has issued a similar guidance policy, with the same mid-term and long-term values. These values were based on work by the California Climate Change Center
