Contract Continuation (Linked)
B. July 1, 2025 City Council Staff Report – Emergency Landslide Stabilization
Contract Continuation and Award of Multiple Contracts for Emergency
Landslide Stabilization and Related Infrastructure Repairs (Linked)
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, as well as the continuation of associated emergency contracting has been
timely renewed and is current.
On July 1, 2025, the City Council awarded multiple contracts for emergency landslide
stabilization and related infrastructure repair work (Attachment A).
On July 15, 2025, the City Council approved continuing the emergency justification for
work and emergency contracting for the Greater Portuguese Bend-Ancient Altamira
Landslide Emergency Project (Attachment B).
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.
The current status of the Deep Dewatering Wells program is the following:
• The DDWs continue to be monitored and re-drilled or replaced as needed
within the current approved budget.
5
•The total combined water extraction rate of the DDWs is currently at
approximately 670 gallons per minute or 0.96 million gallons per day.
•Since the start of the DDW program, approximately 301 million gallons or 907
acre-feet of water have been extracted from certain locations around the toe of
the Landslide Complex. Overall extraction rates have recently decreased due
to the reasons described below:
•DDW-5 has been shut down for pump maintenance and is expected to be
back in service by the end of the week.
•DDW-7 recently sheared and based on the low production rate of this DDWs,
the City’s Geologists are advising that the well be re-located rather than re-
drilled in its approximate existing location. Relocation plans are being
developed using FY2025-26 DDW maintenance and operations funds
approved by the City Council as part of the FY2025-26 Capital Improvement
Program (CIP).
•Bids are being reviewed for re-drilling DDW-8 within a week.
•DDW11 sheared and based on the low production rate, the City’s Geologists
are advising that this DDW should not be re-drilled, but rather re-located,
should additional funding become available. Due to the significant cost of
relocating this DDW, considered to be well above maintenance and
operations, there are currently no plans in place to relocate the well.

Plans for winterization in Fiscal Year 2025-26 are commencing and will be prepared in
advance of the rainy season. Monitoring of winterized areas will be conducted prior to
and during rain events.

The conditions of the landslide complex continue to necessitate the City’s emergency
response.
CONCLUSION:
The effects of the ongoing land movement continue to be felt in the Greater Portuguese
Bend-Ancient Altamira 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 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.
