Subject: Continuation of the Declaration of a Storm-Related Local Emergency for Repair of a Sinkhole on Haymar Drive
Districts: All
Reco
mmended Action
Adopt a resolution continuing the declaration of a storm-related local emergency for repair of a sinkhole in the area of Haymar Drive.
Executive Summary
The City Manager declared a storm-related local emergency on March 24, 2023, to make immediate repair of a sinkhole that was discovered six days earlier on Haymar Drive west of El Salto Falls Street, as shown in Exhibit 3. This sinkhole, which exposed a major sewage pipe, had the potential to cause a sewage spill into the Buena Vista Creek and Buena Vista Lagoon, and the emergency declaration allowed the project to be exempted from the city’s normal bidding procedures so the necessary repairs could be completed as swiftly as possible.
The City Council confirmed the City Manager’s declaration of a local emergency on April 4, 2023, and continued it on April 11, 2023. The staff reports from those meetings are provided as Exhibits 5 and 6. Staff are now recommending the City Council continue the state of emergency to expedite the final phase of repairs: completing repairs to the entire segment of the pipeline in the city right-of-way and installing a new drainage structure.
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.
Explanation & Analysis
The sinkhole was reported to the city on March 18, 2023. Staff determined the sinkhole was likely caused by a failed storm drain pipe carrying runoff water across Haymar Drive and that the damage from the sinkhole endangered the Vista-Carlsbad Sewer Interceptor pipeline, which is above the failed storm drain.

Item #9 Page 1 of 17
This sewage line is a 36-inch diameter iron pipe that carries 4.8 million gallons of wastewater per day to the Encina Wastewater Authority’s Treatment Plant in Carlsbad, with a peak wet weather flow of 14.7 million gallons per day. A break in this pipe would have likely resulted in wastewater draining into the Buena Vista Creek, which is only 700 feet away, and the Buena Vista Lagoon, 2.4 miles away.
The California Department of Transportation informed the city that it relinquished the right-of- way at the sinkhole site to the city in 1967 and has no plans to repair the culvert segment located outside of its right-of-way. Exhibit 4 shows the location of the sinkhole, storm drain pipe and the interceptor pipeline.
City staff swiftly hired a contractor to carry out the emergency repairs needed to prevent a possible sewer leak, and in consideration of an expected rainstorm. Details on the city’s response are in Exhibit 5, the April 4 staff report on the declaration of a local emergency. This report also details how the contractor was selected to carry out the repairs.
The work to secure the interceptor pipeline and make immediate repairs to the storm drain pipe has been completed, and the roadway has been repaved. The remaining work consists of relining the inside of the pipe using a cured-in-place technique, as described in Exhibit 5, and constructing a drainage structure at the asserted boundary between the city and Caltrans’ rights-of-way.
On April 4, staff received a proposal from the contractor for the additional cost associated with the new drainage structure. As of the completion of this report, staff reviewed the proposal and are planning to issue a notice to proceed. The additional work is anticipated to be completed by the end of May or early June.
The continuation of a declaration of a public emergency and the need for an emergency exemption from the formal bidding requirements in Carlsbad Municipal Code Chapter 3.28 – Purchasing are appropriate in this instance because:
• Caltrans relinquished the right-of-way at the sinkhole site to the city in 1967 and has no plans to repair the culvert segment located outside of its right-of-way. • The sinkhole appears to be caused by a failed culvert located in the city right-of-way, which threatened to undermine a critical sewer pipeline. • Immediate repairs were needed to stabilize the sinkhole site and repair the failed storm drain line to prevent the potential spillage of almost five million gallons per day of untreated wastewater into the Buena Vista Creek and Buena Vista Lagoon.

Fiscal Analysis
No additional appropriations are needed at this time. Funding for the estimated $280,000 repair project will come from the fiscal year 2022-23 operating budget – Storm Drain System Rehabilitation and Repair Program.
Options
Staff recommend the City Council continue the declaration of a local emergency to complete the repair of the sinkhole in the area of Haymar Drive as swiftly as possible and prevent a potential sewage spill. Not continuing the declaration would likely result in delays and potentially more costs, with greater risk to the city and no benefits. A four-fifths vote of the City Council is required to continue the emergency declaration.
Next Steps
Staff have begun preparing the emergency contract, which will be presented for ratification to the City Council at a future date. The next phase of work to complete repairs to the entire segment of the pipeline in the city right-of-way and install a new drainage structure is expected to be completed by the end of May or early June.
Staff will return to the City Council on May 9, 2023, to review the emergency action and ask the City Council to determine by a four-fifths vote whether there is a need to continue it.
Environmental E
valuation
The project has been determined to be exempt from the California Environmental Quality Act under CEQA Guidelines Section 15269, which applies to actions necessary to mitigate an emergency and to repair public service facilities necessary to maintain services essential to public health and welfare. Additionally, the project is also exempt under 15301(c), which applies to the operation, repair and/or maintenance of existing utilities involving negligible or no expansion of use.
