Crumby, PE, Director of Public Works SUBJECT: EMERGENCY WATER MAIN REPAIRS ON MARINA AVENUE AND 6T" STREET SUMMARY OF REQUEST: That the City Council approve Resolution No. 6511 approving Budget Amendment 15-05-04 to allocate $146,100 to repair a water main break at the intersection of Marina Avenue and 6th Street. BACKGROUND AND ANALYSIS: On Monday August 25, 2014, at around 12:00 pm, staff was notified of a potential water discharge in the area of 6th and Marina. Public Works (PW) staff visited -the site and immediately identified the problem as a main break. Water Department staff set out to localize the break and turn off the surrounding valves in the area in order to stop the flow of water. Staff then contacted Charles King Company to fix the break for the City. All of the work necessary to repair the main break repair and restore all damaged water lines, valves, and roadway pavement that was damaged during the main break and subsequent flooding, took eight days at a cost of$146,036. A quick synopsis of the work that took place is as follows: August 25, 2014 At 12:00 pm on Monday, August 25th, a 12-inch water main break was identified in the intersection of Marina Avenue and 6th Street. Public Works crews isolated the section of pipe and stopped the flow of water. Doing so, unfortunately, put several local businesses out of water until the break could be fixed. The water main break was larger than the City's public works crews could repair. As such, the Public Works Department called in Charles King Company on an emergency basis to locate and repair the broken water main. Charles King Company has successfully completed utility projects in Seal Beach and had crews within the City working on another project. Charles King Company mobilized a crew, equipment and materials to Seal Beach to excavate and locate the broken water Agenda Item H main. It took several hours to expose and locate the break within the water main. Once the leak was located, the broken section of pipe was cut out and new piping was installed. Water was restored to local businesses by approximately 10:30 pm that evening. August 26, 2014 During a water main break, water valves in the surrounding area are closed. Closing of valves stops water from continuing to flow out of the pipe, and allows the repair to begin. Valves are critical to keeping the area of the shut down as small as possible in regards to turning off water for surrounding businesses and residents. During the shut-down for this water main break, a valve on 5th St. near PC , on another 12-inch water line, broke and was leaking. Due to the nature of the break, this valve had to be removed and replaced, as well as a new valve adjacent to the existing broken valve. During the excavation for this valve, replacement contaminated soils were encountered originating from a gas station cleanup in progress at the intersection. Per California state law, upon encountering the contaminated material, a Geotechnical firm, Stantech, had to be notified of the contamination (they are contracted with Chevron to oversee the remediation of the old gas station) and Charles King was required to stop excavating until a soils investigation could be conducted. Charles King Company crews awaited authorization to complete the valve replacement. August 27, 2014 Stantech and Charles King Company received soil testing results and developed a plan to allow for completion of the new valve. On Marina and 6th Street, the underlying soil had been compromised by the large water main break. A large section of the asphalt and concrete for the street needed to be removed and replaced. Charles King Company began removal of the failed areas. August 28, 2014 —August 29, 2014 1h The intersection of Marina Avenue and 6 Street had concrete poured on August 281h and the first layer of asphalt was placed on August 29th. The work on Marina and 6th was performed remarkably fast in order to have the intersection reopened for the Labor Day Holiday. The new valve was installed on Pacific Coast Highway and 5th Street and covered with a steel plate for the weekend. September 2, 2014 — September 4, 2014 The entire project was completed which included completion of the new valves and final paving for both locations.
