White Point Landslipe Palos Verdes, CA By Christian Kesler, Savannah Keane, and Sarva Pulla

Site information Palos Verdes, CA On a bluff overlooking the Pacific Ocean Roadway along top of the bluff

Before failure - 2011

After failure - 2013

After failure - 2014

After failure - 2015

Utexas analysis before failure Setup the location Found distances and slope from Google Earth Distributed load for the roadway

Utexas analysis before failure

Utexas pre-emptive solution 7 Reinforcement Lines 108 feet in length Total cost is approximately $453,000

UTExas pre-emptive solution

results pre-emptive failure with reinforcements Actual failure OF SLOPE pre-emptive failure with reinforcements FS = 1.371 COST TO FIX = $32,000,000 FS = 1.465 COST TO PREVENT = $453,000

CURRENT CONDITIONS Currently the road is blocked off on both sides of the slide Construction to begin in 2019 Expected construction time is 2 years

Recommendations Dewatering on the eastern flank Slope anchoring using post-tensioned tieback anchors Reinforced Soil Slope (Granular Fill with steel or geosynthetic reinforcement) Retaining Wall Bridge Regrading
