After months of galvanizing. collaborative community and neighborhood leadership by Terry Miller, Dave Behar, Mike Browne, Richard Havenick and the Coastal Neighborhood ad hoc Landslide Committee, the City’s Engineering Team and related agencies, including Council District 15, have released the report we have been waiting for.
Department of Engineering committed to completing the Palisades Residents Association initiated “turnarounds” at the ends of Paseo Del Mar, within the next few months for the needed temporary traffic flow and crime mitigation solution.
The White Point Landslide Report is now available at: http://eng.lacity.org/whitepoint/whitepointlandslide.htm
Preliminary (new) FAQ form the City:
1. Is the land currently stable?
Yes. No movement has been detected since the November landslide.
2. What are the causes?
Water and gravity. Precipitation, irrigation, and to a lesser extent, coastal bluff erosion may have contributed to the development of the White Point Landslide. Residential development in the area may have also contributed to the landslide because of its influence on groundwater infiltration.
3. What needs to be done immediately to protect the area around the slide?
Dewatering, ground anchors, and grading should be done before the next rain season. This will cost $6 to $7 million and will be undertaken immediately by the City.
4. What are the options for long term remedies?
1) re-routing the road around a landslide buffer zone ($4 to $8 million)
2) partially re-grading the landslide debris and adjacent area to restore the road to its previous alignment across the existing landslide ($4 to 8 million)
3) supporting the road at its previous alignment with a soil buttress ($42 to $50 million)
4) supporting the road with a retaining wall ($22 to $27 million)
5) or spanning the landslide with a bridge ($57 to $62 million)
These 5 options have obvious financial concerns and some legal implications that will need to be considered in the upcoming months. Most importantly, the public will be consulted to come up with the best solution for the immediate neighborhood and the community at large.
