Lessons Learned

  • Carpinteria Beach recovered more quickly due to larger waves and sandier sediments
  • Goleta Beach recovered more slowly due to smaller waves, larger volume of sediment and more cobbles
  • The sorting area at Ventura Fair Grounds was important for dealing with the debris flow sediments
  • Pre-existing funding and environmental permits are critical for taking full advantage of opportunistic sediment sources
