BACKGROUND:
On October 3, 2023, the City Council adopted Resolution No. 2023-47, declaring a state
of local emergency relating to the land movement in the landslide complex. The state of
emergency has been timely renewed and is current. On May 7, 2024, the City Council
extended the Local State of Emergency pursuant to Resolution No. 2024 -20 and
approved, among other things, a Public Works Contract with Malcolm Drilling Inc.
(Malcolm) to perform the work of the Portuguese Bend Landslide Emergency Hydraugers
Project (Attachment F). On May 21, June 4, June 18, July 2, July 16, August 6, 2024, and
August 20, the City Council reconfirmed, by a four-fifths vote, that there is a need to
continue the work on the Portuguese Bend Landslide Emergency Hydraugers Project
(Attachments A through H).
DISCUSSION:
Pursuant to Public Contract Code § 22050, the City Manager and Director of Public Works
must report to the City Council at its regular meeting the reasons justifying why the
emergency continues to exist and why action outside of the normal bidding process is
necessary to respond to the emergency. Furthermore, Public Contract Code § 22050
states that the City Council shall, at every regularly scheduled meeting , consider and
reaffirm that there is a need to continue to remediate the emergency until the authorized
emergency repairs have been completed. Accordingly, because the work has not yet
been completed, this item is on tonight’s agenda. This item will be placed on each
subsequent agenda until all aspects of the project are completed.
Since the most recent update to the City Council on August 6, 2024, the need for the
emergency work is ongoing. The status of the project at the time of publication of this staff
report on August 27, 2024 is as follows:
• Drilling of the vertical boreholes landward of Palos Verdes Drive South (PVDS)
for Emergency Hydrauger E-1 (E-1) is complete.
• Four originally planned boreholes seaward of PVDS for E-1 have been completed
• Work on a newly added fifth borehole seaward of PVDS is ongoing.
• A second drill rig has been mobilized and drilling of boreholes towards the head
of the slide has started.
• A revised borehole plan to collect data across the breadth of the landslide complex
is being prepared.
• Instrumentation to collect data on subsurface characteristics continues to be
installed in each borehole.
• Mapping of the depths and shapes of underwater terrain (bathymetry survey) is
underway to obtain more information about the lower section of the landslide
located along the coast.
2
• Specifications for deep vertical dewatering wells to address the deeper slide are
being finalized. Schedules and cost estimates are being prepared.
• Environmental monitoring is being conducted in conjunction with construction
activities.
The emergency conditions necessitating the project are likely to persist at least until
completion of the project.
CONCLUSION:
The effects of the ongoing land movement continue to be felt in the Greater Portuguese
Bend Landslide Complex. Staff recommends reconfirming that there is a need to continue
to remediate the emergency identified by City Council-adopted Resolution No. 2024-20
(originally by Resolution No. 2023-47), and reconfirm, by a four-fifths vote, the need for
continuing the work on the Portuguese Bend Landslide Emergency Hydraugers Project.
ALTERNATIVES:
In addition to Staff recommendation, the following alternative action is available for the
City Council’s consideration:
1. Take other action or provide direction, as deemed appropriate.
