FOR THE GOLDRING WELL PIPELINE AND STORM DRAIN PROJECT AS COMPLETE CEQA: Mitigated Negative Declaration / Notice of Determination Filed Recommendation: Approve SUMMARY On June 17, 2025, the City Council approved a contract with All Cities Engineering Inc. in the amount of $916,920 for the Goldring Well Pipeline and Storm Drain Project. The terms and conditions of this project have been complied with, and the work has been performed to the satisfaction of the Project Manager for a total project cost of $898,748. This reflects the approved contract amount of $916,920 minus contract change orders totaling $18,172, or 1.98% less than the approved contract amount. It is recommended that the City Council accept all work performed by All Cities Engineering Inc. for the Goldring Well Pipeline and Storm Drain Project as complete and authorize the final payment to be made in accordance with the contract documents, subject to the retention of $44,937.40. BACKGROUND The City serves water to over 57,000 residents, primarily with water pumped from the Main San Gabriel Basin, West Raymond Basin, and the East Raymond Basin. To enhance the existing water supply infrastructure, Arcadia is partnering with the City Accept Goldring Well Pipeline and Storm Drain Project May 5, 2026 Page 2 of 4 of Sierra Madre to construct a new water supply well (Goldring Well) in the Main San Gabriel Basin. On November 17, 2020, the Arcadia City Council approved a New Joint Groundwater Production Well Agreement between the Cities of Arcadia and Sierra Madre to jointly design, construct, operate, and maintain a groundwater production well in the Main San Gabriel Basin. Per the terms of the Joint Agreement, Arcadia and Sierra Madre are each responsible for 50% of the cost of all matters related to the new well. In March 2023, in response to increased concerns over Per- and polyfluoroalkyl substances (“PFAS”, also known as “forever chemicals”), the Environmental Protection Agency (“EPA”) published proposed regulations that would set Maximum Contaminant Levels (“MCL”) for select PFAS contaminants. PFAS can be found in products such as food packaging and commercial and household products, which often end up in groundwater and are toxic at relatively low concentrations, presenting a danger to both human health and the environment. On June 20, 2023, the City Council approved an amendment to include PFAS treatment for the new well to address PFAS that had been detected in other groundwater sources within the vicinity of the Goldring Well. The Goldring Well and PFAS Treatment Project consists of the construction of a new groundwater production well, a PFAS treatment plant, a new 30,000-gallon backwash tank with a new 4-inch diameter sewer pipeline, a new 12-inch diameter ductile iron water main, and a new 30-inch diameter Reinforced Concrete Pipe (“RCP”) pump-to- waste storm drain pipeline. The water, sewer, and storm drain pipelines need to be completed before the new well drilling begins. The storm drain pipe is approximately 1,400 feet in length, starting from the well site, going westerly on Randolph Street, and connecting to the existing 57-inch RCP on Peck Road. The 12-inch diameter ductile iron water main and 4-inch sewer main connect from the well site to the existing water and sewer mains on Kardashian Avenue. DISCUSSION On June 17, 2025, the City Council approved a contract with All Cities Engineering Inc. for the Goldring Well Pipeline and Storm Drain Project. The project included excavation; construction of 18-inch, 24-inch, and 30-inch diameter reinforced concrete pipelines with appurtenant manholes and catch basins; 12-inch diameter Accept Goldring Well Pipeline and Storm Drain Project May 5, 2026 Page 3 of 4 ductile iron pipeline; 4-inch diameter PVC drain line; ¾-inch diameter Type K copper pipe; interconnections with existing storm drains, sewers, and water lines; 4-foot by 5-foot Jensen precast concrete sampling vault; pavement rehabilitation; curb and gutter; cross gutter/spandrel PCC pavement rehabilitation; and striping/pavement markers. All terms and conditions of the contract have been complied with, and the work has been performed to the satisfaction of the Project Manager. All Cities Engineering Inc. completed the work as defined in the project plans and specifications, in an efficient and timely manner. During the course of the work, it was determined that less storm drain pipes were needed to complete the project and there were sections of cross gutter that did not have to be replaced. This resulted in an overall reduction to the original contract amount. The final cost of the Goldring Well Pipeline and Storm Drain Project is $898,748. This amount reflects the approved contract amount of $916,920 minus contract change orders totaling $18,172, or 1.98% less than the approved contract amount. ENVIRONMENTAL ANALYSIS Pursuant to the provisions of the California Environmental Quality Act (“CEQA”), an Initial Study/Mitigated Negative Declaration (“IS/MND”) was prepared to evaluate the potential environmental effects associated with the implementation of the Goldring Well and PFAS Treatment Project. The IS/MND found that there would be either no impact or less than significant impact on all resources, with the exceptions of Air Quality, Hazards and Hazardous Materials, Noise, and Tribal Cultural Resources. These four resource categories were found to have “Less than significant Impact with Mitigation Incorporated.” The Draft IS/MND was circulated for public review and comments for 30 days from February 10, 2025, to March 11, 2025. On April 1, 2025, the City Council adopted the IS/MND for the Project, approved the Mitigation Monitoring and Reporting Program, and authorized the execution of the Notice of Determination. On April 3, 2025, the Mitigated Negative Declaration/Notice of Determination was filed with the Los Angeles County Clerk and was published with the State Clearing House. The CEQA process has, therefore, been completed. Accept Goldring Well Pipeline and Storm Drain Project May 5, 2026 Page 4 of 4 FISCAL IMPACT Funds in the amount of $1,085,000 have been budgeted in the Fiscal Year 2023-24 Capital Improvement Program for the Goldring Well Pipeline and Storm Drain Project. The total cost for the Project is $898,748. This amount reflects the approved contract amount of $916,920 minus contract change orders totaling $18,172, or 1.98% less than the approved contract amount. The cost share for the City of Arcadia is $521,865.50, and the cost share for Sierra Madre is $376,882.50. Arcadia’s cost share is higher because it includes additional costs for increasing the storm drain pipe from 18-inches to 30-inches, and installing catch basins, curb and gutter, and cross gutter to address local storm runoff and a ponding issue that will impact Arcadia exclusively, but are included in this project for efficiency and expediency. RECOMMENDATION It is recommended that the City Council determine that the Project has been completed in accordance with the California Environmental Quality Act (“CEQA”); and accept all work performed by All Cities Engineering Inc. for the Goldring Well Pipeline and Storm Drain Project as complete, and authorize the final payment to be made in accordance with the contract documents, subject to the retention of $44,937.40.
