Document Description
Two landslides have occurred - one in 2006 and another in 2011. A total of seven homes have been red-tagged and/or demolished as a result of these landslides. At least five other properties have sustained significant damage. Near vertical head scarps are present at both landslides. The project will repair slope failures adjacent to the 5th Hole of Shore cliffs Golf Course so that it prevents further failures and loss of property. Project activities consist of the installation of a 7 foot by 6 foot box culvert from the I-5 Freeway to the Via Cascadita storm drain, for the purpose of carrying nuisance water and storm flows that have eroded the toe of the slope over time.
