CA TOURISM & RECREATION
(Kildow & Colgan 2005)

THE CA BEACH ECONOMY
USE
13.1 Million Californians visited beaches (Leeworthy 2001)
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)

CA COASTAL EROSION
(Griggs 2005)

SHORELINE ARMORING
Ventura, LA, Orange & San Diego County
Statewide
(Griggs 2005)

CA COASTAL ACT Section 30225
Shoreline armoring shall be permitted when required to protectexisting structures in danger from erosion

CA COASTAL ACT: MITIGATION
…and when designed to eliminate or mitigate adverse impacts on local shoreline sand supply.

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
2009: Neptune: Replacement Approach
2010: City of Solana Beach: Site Specific Study
BEACH ECOSYSTEMS (Ecosystem services question)
Not included

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

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

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?
