Subject: Continuation of Proclamation of a Storm-Related Local Emergency for Repair of the Slope Between El Camino Real and Trieste Drive, Approval of Plans and Authorization of Additional Appropriations for this Emergency
District: 1
Recommended Action
Adopt a resolution continuing the proclamation of a storm-related local emergency for repair of the slope between El Camino Real and Trieste Drive, approving the plans and authorizing additional appropriations in the amount of $955,000 for the Trieste Drive Slope Repair, Capital Improvement Program Project No. 6107.
Executive Summary
The atmospheric river in early February 2024 and the winter storm in January 2024, resulted in unexpected slope movement in an area between El Camino Real and Trieste Drive, with potential to affect nearby property, infrastructure, and the environment. Emergency repair of the slope area behind four homes on Trieste Drive is necessary to ameliorate the risk. Exhibit 4 shows the area requiring emergency slope repair.
The City Manager, in his role as Director of Emergency Services, proclaimed a local emergency on Feb. 14, 2024, as shown in Exhibit 2, to expedite the slope repair. On Feb. 15, 2024, the City Council ratified the emergency proclamation so that the repair can continue to be exempted from the city’s normal bidding procedures and the necessary repairs can be completed as swiftly as possible. On Feb. 27, 2024, the City Council continued the emergency proclamation.
Staff are requesting that the City Council continue the emergency proclamation again to complete the work.
Construction projects that cost less than $200,000 can be awarded by the City Manager using informal bidding procedures under Carlsbad Municipal Code, or CMC, Section 3.28.080 – Construction Projects, subsections (B) and (H), which implement California Public Contract Code Section 22032.
This project will cost approximately $3 million. Public Contract Code Sections 22035 and 22050 and CMC Sections 3.28.110(A) and 3.28.120 provide for an exemption from formal bidding March 12, 2024

procedures for emergency construction procurements. The emergency proclamation allows the city to use the exemption. However, California Public Contract Code Section 22050(c)(1) requires the City Council to review the emergency action at every subsequent City Council meeting to determine, by a four-fifths vote, whether there is a need to continue the emergency action.
Staff recommend that the City Council continue the proclamation of the storm-related local emergency to allow for the swift repair of the slope, and approve the plans in Exhibit 3 and authorize additional appropriations in the amount of $955,000 by approving the resolution provided as Exhibit 1.
Explanation & Analysis
The slope area between El Camino Real and Trieste Drive, generally behind the backyards of four residential properties that front onto Trieste Drive (4215-4245 Trieste Drive), has experienced soil movement. The city has a Capital Improvement Program project (Project No. 6107) to repair the slope. The project was in the 50% design and environmental review stage.
However, the recent severe storm events have created additional fissures in the soil that need to be repaired quickly.
The City Engineer recommended expedited, or emergency, stabilization of the slope while the larger slope repair project proceeds through the design and environmental review and permitting process. The emergency proclamation allows the city to procure a contractor to perform the necessary emergency work to prevent or mitigate loss of, or damage to, property, essential public services and the environment.
Staff and Urban Corps completed emergency protective measures at a cost of $5,774, which included debris removal and placement of tarps and stakes in the right-of-way.
Upon proclamation of the emergency, Engineering Systems Inc., the city’s geotechnical engineering consultant, met with contractors to check on their availability and capabilities to perform the emergency work. Condon-Johnson & Associates, Inc. provided a cost estimate of $871,000 for the emergency work.
The emergency work was initially intended to address the unexpected slope movement that occurred as a result of the recent atmospheric rivers and storms, not to perform the original scope of work of the Capital Improvement Program project. However, due to recent further slope movement, the city’s geotechnical engineering consultant has recommended performing the additional final repairs at the same time as the emergency work.
The contractor Condon-Johnson’s estimate increased to $2,087,090 for the total cost, which includes the initial estimate of $870,990 for installation of 26 emergency shore stability pins, which stabilize the slope, and $1,216,100 for installation of an additional row of 28 shore stability pins and other more permanent repairs such as grading and re-compaction of the slope within the repair area, as shown in the plans in Exhibit 3.
On March 6, 2024, staff issued a notice to proceed to the contractor to perform the emergency work.
The emergency work is expected to start on March 12, 2024, and is expected to be completed by May 17, 2024.

Fiscal Analysis
Funding for the estimate of up to $2,023,626 for the emergency work will come from the funding in the General Capital Construction Fund for Capital Improvement Program Project No. 6107. Since the total emergency work will now include placement of an additional row of shore stability pins and slope grading and re-compaction, additional funds in the amount of $955,000 will need to be appropriated to Capital Improvement Program Project No. 6107 to cover the rest of the needed funding.
Due to an increase in the emergency scope of work, staff have also increased the additional design, administrative, construction management, inspection and environmental monitoring costs that are anticipated.
This emergency work could qualify for outside funding. The City Manager sent a letter to the California Governor’s Office of Emergency Services on Feb. 22, 2024, requesting any and all state and federal resources including, but not limited to, state assistance through the California Disaster Assistance Act. The state replied and subsequently requested supplemental information on the city’s budget and how recent storms impacted it. On Feb. 26, 2024, staff provided the requested supplemental information and the initial damage estimate of $1,293,774, which has now increased to almost $3 million.

Local Emergency - REPAIR OF THE SLOPE BETWEEN EL CAMINO REAL AND TRIESTE DRIVE
3. Prior to the early February 2024 storms, powerful winter storms that occurred less than a month ago had amplified the impact of local flooding due to the record-breaking a·mount of rainfall including a severe rainstorm which began on January 22, 2024 ("January Storm"), in all dropping 2 to 3 inches of rain in a three-hour period, a total that exceeds that of an average wet month and rivals the rainfall needed to spur a 100-year flood event.
4. On Jan. 22, 2024, the County of San Diego proclaimed an emergency due to the January Storm, which the county characterized as a thousand-year storm, and which caused drastic flooding and flash flooding in the county.
5. The conditions of the early February 2024 storms, in addition to the impacts of the January Storm, created an emergency condition on a slope that is located between El Camino Real and Trieste Drive, generally behind the backyards of four residential properties that front onto Trieste Drive (4215 - 4245 Trieste Drive) causing rapid slope movement and additional fissures in the soil that warrant immediate emergency repair.
6. That the City Council of the City of Carlsbad was not in session and could not be immediately called into session.
NOW, THEREFORE, IT IS PROCLAIMED that, subject to review and ratification by the City Council at its next meeting, a local emergency now exists in the City of Carlsbad, California, on a slope between El Camino Real and Trieste Drive, generally behind the backyards of four residential properties that front onto Trieste Drive (4215 - 4245 Trieste Drive).
IT IS FURTHER PROCLAIMED AND ORDE D that, under California Public Contract Code Section 22050 and Carlsbad Municipal Code cti ns 3.28.llO(A) and 3.28.120, city staff may proceed at once to obtain the necessary pe mits, quipment, services, and supplies to repair the slope between El Camino Real and Trieste Dn enerally behind the backyards of four residential properties that front onto Trieste Driv - 4245 Trieste Drive), without giving notice for bids to let contracts.
