DESCRIPTIONPresented at the fall 2010 meeting of the American Geophysical Union in San Francisco, CA.
- 1. Nicole Russell Ph.D. Student Department of Earth and Planetary Sciences Gary Griggs Director Institute of Marine Sciences University of California Santa Cruz
- Coastal counties: 24% of CAs area but home to 80% of Californians
- ~35 million visitors/yr and $23 billion/yr
Malibu, CA 3.
- OPC has adopted 10-17 inch rise by 2050 & 40-55 inch rise by 2100
- Current global rate: ~2-3 mm/yr
- Rate may be increasing
- Besides, local rates matter most
- 4.24 ft/100 yrs
- (-12.92 mm/yr)
noaa.gov Louisiana + 3.03 ft/100 yrs (+ 9.24 mm/yr) 6. California + 0.66 ft/100 yrs (+ 2.01 mm/yr) 7. 8.
- Inundation of low-lying areas
Main Beach, Santa Cruz 2008 Lynne Harden 9.
- Passive erosion
Projection: 3 foot sea level rise by 2100 10.
- Inundation: weve seen it before
Mission Beach, San Diego Winter 1988 11. San Francisco Airport with 16 inches of sea level rise 12.
- Increased cliff erosion

- Storm damage
Pacifica 1998 15.
- Santa Cruz Boardwalk, 1926 ElNio
- Boardwalk during 1997-98 El Ni o
- Every community has a unique geographic setting and people
- Planning officials must understand local vulnerabilities in order to form appropriate adaptation strategies
- Well-documented disconnect between science and practice
- Improve transfer of relevant information from scientists to decision-makers
- i.e. local SLRflood levelsnew flood hazard maps;
- coastal cliff retreatsetbacks
Plan Santa BarbaraDraft Environmental Impact Report 19.
- Perform SLR vulnerability assessments for two specific coastal communities in order to identify:
- Range of hazards
- Types of information needed for assessing vulnerability
- Range of available adaptation approaches
- Recommended adaptation strategies
- Create a guide for developing local mitigation plans
- Vulnerability assessments
