  2. Draft Guidance: City and County of SF

  3. SLR Depictions: SFO: 3 feet Port Study: 15 and 55 inches (URS, 2011) BCDC: 2 meters (2007) NOAA Coastal Viewer (1-6 ft, 5 ft pictured)

  4. April 10, 2014 issue of The Urbanist (SPUR)

  5. The Wild Wild West …

  6. Current SLR Estimates: CCSF Depts, Projects 205020802100 SFMTA 24 60 SFO 16 55 SLR in inches PUC (SSIP) 11-24 36-66 TI/YBI 16 36 55 Port (URS) 10-17 31-69 Ocean Beach 14 55

  7. CCSF Sea Level Rise Guidance • Focus set by Mayor’s Office: • Draft guidance for incorporating sea level rise into capital planning for the CCSF • Bring draft guidance to Capital Planning Committee for consideration • Enable CPC and departments to better understand and prioritize projects with reference to sea level rise • Coordinate and encourage collaboration among all CCSF departments • Maintain responsibility for assessment and adaptation within departments, with review and coordination by entity TBD.

  8. Sea Level Rise Committee Members • David Behar, PUC (Chair) • Lauren Eisele, Port • Rosalyn Yu, SFO • Frank Filice, DPW • Craig Raphael, MTA • AnMarie Rodgers, Planning • Chris Kern, Planning • Tania Shayner, Planning • Nohemy Revilla, PUC/SSIP Liaison • Anna Roche, PUC/Wastewater • Brian Strong, Capital Planning • Kris May, AECOM/SSIP • Dilip Trivedi, Moffat & Nichol Meetings • Began September 27 and approx every two weeks since. Activities • Benchmarking review of other jurisdictions: local, state and national • Survey of CCSF activities with SLR nexus (many found) • In-depth review of the science • Survey of regulatory context • One half-day workshop • Writing Draft Guidance

  9. A Range of Ranges: “Confusion Meets Catastrophication” Sea Level Rise – 210S 2100 - RANGES 39 10

  10. Science and Regulatory Landscape – a sampling

  11. CCSF Draft Guidance: Flexible; Considers Both Likely and Extreme Scenarios; Reflects Best Available Science

  12. CCSF Draft Guidance: SLR Figures Sea Level Rise Scenarios – 21st century (inches)1 1from National Research Council 2012

  13. Sea Level Rise and Extreme Tide Matrix Source: SFPUC, Sewer System Improvement Program (AECOM)

  14. Source: Sewer System Improvement Program, Draft Inundation Maps Assumes no adaptation measures implemented 2100 Most Likely SLR + Events* 36” SLR 36” SLR + King Tide (48” total) 36” SLR + 100 year flood (77” total)

  15. SLR Guidance: Steps in the Process • 1. SLR Science Review • 2. Vulnerability Assessment • 3. Risk Assessment • 4. Adaptation Planning • . . . Permitting and Regulatory Considerations

  16. Elements of Draft SLR Guidance (cont) 2. Vulnerability Assessment: Which assets are vulnerable to sea level rise? • A. Exposure • B. Sensitivity • C. Resilience

  17. Elements of Draft SLR Guidance (cont) 3. Risk Assessment: Which vulnerable assets are at greatest risk (prioritization opportunity)? • A. Likelihood • B. Consequence

  18. Elements of Draft SLR Guidance (cont) 4. Adaptation Planning: For those assets at risk, what will we do to increase their resilience to sea level rise? • Building on previous steps to create resilience • Adaptive capacity, adaptive management

  19. Elements of Draft SLR Guidance (cont) 5. Permitting and Regulatory Considerations • Coastal Commission • BCDC • CCSF General Plan

  20. “Adaptive Capacity” Two definitions in literature we’ve reviewed: 1) Inherent resilience: asset will be flooded but not be harmed, or flooding will not be a problem. Examples: a) a park floods, but it’s not harmed; b) A road floods, but another road is available for use 2) Adaptive management: asset can be made resilient to shorter term SLR, and planning/footprint can allow future resilience measures when more is known.

  21. “ADAPTATION” Raise Embankments

  22. “ADAPTIVE MANAGEMENT” Raise Embankments…Again!

  23. Treasure Island - Sea Level Rise Approach Elevated Development Area Wide Setback Areas to Allow Future Adjustment for Sea Level Rise Adaptive Strategies at Perimeter Establish Project Generated Funding Mechansim
