ATTACHED SUPPORTING DOCUMENTS:
A. December 2, 2025 City Council Staff Report – Emergency Landslide
Stabilization Contract Continuation (Linked)
B. September 16, 2025 City Council Staff Report – Landslide Update (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 and providing
the City Manager authorization to approve matters related to the emergency for
ratification by the City Council. The state of emergency, as well as the continuation of
associated emergency contracting has been timely renewed and is current.
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 City Council most recently approved continuing the emergency justification for work
and emergency contracting for the Greater Portuguese Bend-Ancient Altamira Landslide
Emergency Project on December 2, 2025 (Attachment A) and is therefore due to reaffirm
the need to continue to remediate the emergency at this evening’s meeting.
DISCUSSION:
Re-affirm Need to Continue Emergency Work
To support the need for continued emergency contracting authority, the current status of
the Deep Dewatering Wells (DDWs) and winterization programs is being provided:
Since the start of the DDW program in September 2024, approximately 407 million
gallons, or 1,248 acre-feet of water have been extracted. Extraction rates are currently
influenced by the following circumstances:
o DDW11 has 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 operation costs, there are
currently no plans in place to relocate the well.

Status of Winterization Measures
Following City Council direction on September 16, 2025 (Attachment B), staff finalized
the scope of work for implementing winterization measures ahead of the rainy season.
The work started early last month and will be completed by mid-December 2025.
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.
