Transcript

  • 1. THE IMPACT OF SHORELINE ARMORING ON CALIFORNIA’S OCEAN ECONOMY
    CHAD NELSEN
    SURFRIDER FOUNDATION
    CALIFORNIA AND THE WORLD OCEAN

    150 million beach visits (Pendleton & Kildow 2006)
    ECONOMICS
    $14 Billion in direct revenues (King, 1999)
    ~$8 Billion in non-market value (Pendleton & Kildow 2006)
    Beach loss: $8.3 billion (King & Symes 2003)

  • 10. CCC APPROACHES TO MIGITATION
    • SAND (Engineering question)
    CCC Procedural Guidance Document
    • LOST RECREATION (Economics question)
    2004: Ocean Harbor House: Acreage Approach
    2005: Las Brisas: Amenity Approach

  • 11. CONCLUSIONS
    Beaches: important to CA Ocean Economy
    CCA continues to allow shoreline armoring
    Mitigation for beach loss is incomplete
    Mitigation program needs improvement
    Alternatives to armoring are essential
  • 12. RECOMMENDATIONS
    Standardize Recreational Value Approach
    Day use value
    Climate change
    Procedural Guidance Document
    Develop ecosystem services model
    Research on beach ecosystem service values
    Seek alternative to armoring: Managed Retreat
  • 13. QUESTIONS
    What does mitigation of adverse impacts mean?
    Where does the money go?
    Will it be enough?
    What does the future look like with a robust mitigation program?
    Are there better alternatives? What are they?
