Abstract
This study examines how climate driven sea level rise and extreme storm events affect beach width and economic value across Southern California. It evaluates two key impacts: permanent beach loss from one meter of sea level rise and short term erosion and accretion from extreme storm conditions based on the 1982 to 1983 El Niño year. Using a random utility model of beach attendance, the research analyzes how different user groups respond to changes in beach width across 51 public beaches in Los Angeles and Orange Counties. The study finds that narrower beaches reduce overall recreational value, with impacts varying by activity type and location. While some beaches may experience increased attendance, others face declines in visitation and related expenditures. The findings show that economic losses from a single stormy year can rival those from long term sea level rise. The study also provides cost estimates for beach nourishment as a potential adaptation strategy.
