Project 183 - Agenda Staff Report - 2008-07-08 (7 414 q 4 w� q¢ �8 u w COSTA MESA SA9[I7�DIS2 ,IC`rr 0 i'posatt��� an Independent Special District Memorandum 441t-um To: Board of Directors From: Robin B. Hamers, Manager/District Engineer Date: July 8, 2008 Subject: Project #183 — System-Wide Sewer Repair— Project A Recommendation to Authorize Construction Project #183 System Wide Sewer Repair is included in the District's Capital Improvement Program (CIP) for the 2008-2009 fiscal year and the subsequent three fiscal years. The project was included in the 5-year CIP to establish a yearly revenue stream to fund the repair projects identified from the District-wide televising project. The repair project under consideration is the `hotspot ("hotspot' being defined as a section of sewer that requires constant cleaning or cleaning more often than once per year) in Victoria Street at Harbor Blvd. The District's Maintenance Supervisor considers this hotspot as one of his two worst problem areas in the District as he is forced to mobilize the sewer cleaning crew and spend over three hours, usually on overtime, at three-month intervals to remove the debris and grease that collects in the line. The hotspot is directly in the center of the intersection of Harbor Blvd. and Victoria Street and requires extensive traffic control to maintain a safe working area. The hotspot is being caused by two components; there is a 'sag' (low point or belly) in the 40-foot long section of 12-inch gravity sewer plus the Victoria Pumping Station force main discharges into the line just past the sag. Both of these components serve to slow down the flow to a point where debris and grease collect and form a plug. Even though the District's FOG program is successfully reducing grease from the tributary food service establishments, there is grease being discharged from the residences in the area. The corrective measure is to remove and reconstruct the 40-foot long section of gravity sewer and to remove the force main from its current discharge point and reconnect it further downstream in the system. Project #183 — System-Wide Sewer Repair— Project A July 8, 2008 Page 2 The funds to correct this hotspot only became available on July 1 2008 when the new CMSD budget became effective. At the same time, the City of Costa Mesa is nearing completion of a street rehabilitation project for Victoria Street and held up their contractor from his 'final paving' for the intersection to allow the District to perform the corrective measures. After the final paving is installed, there will be a five year moratorium on working in the street, which would prevent the District from correcting the problem for at least five years. As it stands, the District will be charged a 're-mobilization' charge of approximately $4,000 by the City's contractor for his delay However this is much less than the District would spend repaving the sewer trenches and work area due to the extent of the sewer work. The Manager/District Engineer has made arrangements with one of the contractors under an Emergency Work Agreement with the District, GCI Construction, Inc. to mobilize his forces to reconstruct the sewer as shown in the attached construction plans. Also attached is the Engineer's Estimate for the work. Based on the reasons stated above it is recommended the Board of Directors make the following findings by a 4/5 vote: 'Based on the condition of the existing gravity sewer and force main in the intersection of Victoria Street and Harbor Blvd. including but not limited to those being in a deficient operational condition and constantly causing the sewer to back up the potential harm to Costa Mesa Sanitary District workers from working in a high volume traffic intersection, and the need to repair those facilities immediately to prevent a sewer spill that would be detrimental to the public health as well as the disruption of essential public services, and considering the five-year pavement trenching moratorium that will be imposed, there is hereby declared to be a public emergency requiring immediate action on the part of the District to authorize GCI Construction, Inc. to perform the reconstruction and the Manager/District Engineer to utilize his engineering and management services on a hourly basis to design, inspect, provide construction staking, and administer the construction.
