  • 13.1 million Californians in 1999-2000150 million beach visits 2000
  • Thirty-three percent of the coastlines of Ventura, Los Angeles, Orange and San Diego counties have now been armored.
  • California World Ocean: Shoreline Armoring and the Ocean Economy

    1. 1. THE IMPACT OF SHORELINE ARMORING ON CALIFORNIA’S OCEAN ECONOMY<br />CHAD NELSEN<br />SURFRIDER FOUNDATION<br />CALIFORNIA AND THE WORLD OCEAN<br />SEPTEMBER 2010 <br />
    2. 2. CA TOURISM & RECREATION<br />(Kildow & Colgan 2005)<br />
    3. 3. THE CA BEACH ECONOMY<br />USE<br />13.1 Million Californians visited beaches (Leeworthy 2001)<br />150 million beach visits (Pendleton & Kildow 2006)<br />ECONOMICS<br />$14 Billion in direct revenues (King, 1999)<br />~$8 Billion in non-market value (Pendleton & Kildow 2006)<br />Beach loss: $8.3 billion (King & Symes 2003)<br />
    4. 4. CA COASTAL EROSION<br />(Griggs 2005)<br />
    5. 5. SHORELINE ARMORING<br />Ventura, LA, Orange & San Diego County<br />Statewide<br />(Griggs 2005)<br />
    6. 6.
    7. 7. CA COASTAL ACT Section 30225<br />Shoreline armoring shall be permitted when required to protectexisting structures in danger from erosion<br />
    8. 8. CA COASTAL ACT: MITIGATION<br />…and when designed to eliminate or mitigate adverse impacts on local shoreline sand supply. <br />

    10. 10. CCC APPROACHES TO MIGITATION<br /><ul><li>SAND (Engineering question)</li></ul>CCC Procedural Guidance Document<br /><ul><li>LOST RECREATION (Economics question)</li></ul>2004: Ocean Harbor House: Acreage Approach<br />2005: Las Brisas: Amenity Approach<br />2009: Neptune: Replacement Approach<br />2010: City of Solana Beach: Site Specific Study<br />BEACH ECOSYSTEMS (Ecosystem services question)<br />Not included<br />
    11. 11. CONCLUSIONS<br />Beaches: important to CA Ocean Economy<br />CCA continues to allow shoreline armoring<br />Mitigation for beach loss is incomplete<br />Mitigation program needs improvement<br />Alternatives to armoring are essential<br />
    12. 12. RECOMMENDATIONS<br />Standardize Recreational Value Approach<br />Day use value <br />Climate change <br />Procedural Guidance Document<br />Develop ecosystem services model<br />Research on beach ecosystem service values<br />Seek alternative to armoring: Managed Retreat<br />
    13. 13. QUESTIONS<br />What does mitigation of adverse impacts mean? <br />Where does the money go?<br />Will it be enough?<br />What does the future look like with a robust mitigation program?<br />Are there better alternatives? What are they?<br />
