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 D). On May 21, June 4, and June 18, 2024, 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, B and C).
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 by a four-fifths vote 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 June 18, 2024, the need for the
emergency work is ongoing. The status of the project at the time of publication of this staff
report on June 25, 2024 is as follows:
• Clearing and grubbing for access to most of the borehole sites is complete.
• Drilling for the first two boreholes is complete. Drilling activities for the third and
fourth boreholes are expected to be completed by the end of the first week of July.
• Additional borehole locations are being prepared and associated instrumentation
with long lead delivery timelines are being ordered ahead of drilling additional
boreholes.
• Environmental monitoring is being conducted in conjunction with construction
activities.
During drilling operations for the first three boreholes, production was impacted by the
presence of soil with a harder composition than originally anticipated. In response, an
additional drill rig is being mobilized to improve the progress for the remaining boreholes.
The second drill rig is scheduled to arrive by the second week of July. The estimated
schedule for completing the boreholes for Hydrauger Array E -1 and analyzing the
resultant data is approximately six to eight weeks , which is greater than the originally
anticipated schedule of four to six weeks. This is partly due to field conditions and the
depth of drilling required.
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, by a four-fifths vote, 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.
