October 21, 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 author ized 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 October 21, 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, approximately 369 million gallons, or 1,131 acre- feet of water have been extracted. Extraction rates are currently influenced by the following circumstances: • DDW-9 is currently offline due to low water level. The City’s Geologists are studying how quickly its water level rises and will then recommend adjustments to the pump’s operation to minimize the risk of it running dry and burning out. • 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. 3 Table 1 - DDW Current Water Extraction Rates as of October 27, 2025 DDW No. Date Operational Current Approximate Water Extraction Rate (Gallons Per Minute) Total Water Extraction to Date Acre-Ft Million Gallons 1 9/13/2024 105 (re-drilled 3/21/25 and 9/25/25) 141 46 2 9/17/2024 85 (re-drilled 5/29/25) 152 50 3 9/21/2024 60 (re-drilled 3/24/25) 143 47 4 9/21/2024 N/A, Decommissioned 3/27/25 104 34 4A 3/29/2025 50 5 9/25/2024 100 (re-drilled 3/26/25 and 9/18/2025)  130 42 6 9/28/2024 70 (re-drilled 12/29/24 and 5/23/25) 124 40 7 10/15/2024 N/A, Decommissioned 6/3/25  15 5 8 10/17/2024 95 (re-drilled 8/14/25) 89 29 9 10/25/2024 N/A, Decommissioned 11/07/24  74 24 9A 11/16/2024 N/A, (re-drilled 12/29/24, 5/10/25, 8/22/25) Currently offline 10 10/24/2024 105 (re-drilled 5/11/25) 157 51 11 12/3/2024 N/A, Decommissioned 3/14/25  2 1 Totals 670 1,131 369 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 earlier this month and will be completed by the end of November or early 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. 4
