Preliminary Design Report Addendum No.2 <br />5.2 OPERATIONS AND MAINTENANCE COSTS <br />As part of the cost evaluation, annual operation and maintenance costs including labor, power <br />consumption, and miscellaneous costs have been developed for each alternative, as explained below: <br />• Power costs were based on total estimated power consumption to run each facility. <br />• Labor costs at each facility include maintenance personnel for seasonal cleaning, O &M at the <br />Diversion Facility; annual inspection; and maintenance at the pump station facility. <br />Miscellaneous costs include Rehabilitation and Repair (R &R) cost, parts, utilities, and general <br />operating supplies. <br />Table 4 -6 presents a summary of the Fiscal Year 2014 Operation and Maintenance Costs for each <br />alternative. The table shows the distribution of operation and maintenance costs spread with percentages <br />of costs for the power, labor and the miscellaneous costs, and their respective percentage of total capital <br />cost for each option. Table 4 -6 shows the O&M costs only account for 0.2 to 0.4 percent of the capital <br />cost. Therefore the cost estimate of the project options are mainly decided by the capital costs, and are not <br />impacted much by the O &M costs. <br />Table 4- 6 O &M Cost Estimates for Four Alternative Options <br />Description <br />Unit <br />Option A <br />Rubber <br />Dam <br />FM Route 3 <br />Option B <br />Rubber <br />Dam <br />FM Route 5 <br />Option C <br />Radial <br />Gates <br />FM Route 3 <br />Option D <br />Radial <br />Gates <br />FM Route 5 <br />Power Required for Pump <br />kwh/yr <br />930 <br />2,780 <br />930 <br />2,780 <br />Power Required for Blower <br />kwh/yr <br />2,500 <br />2,500 <br />Total Yearly Power Cost <br />$ /yr <br />343 <br />278 <br />343 <br />278 <br />Labor <br />Total Yearly Labor Cost 2 <br />$ /yr <br />3,048 <br />3,048 <br />3,048 <br />3,048 <br />Miscellaneous <br />Debris Cleaning (30 tons <br />annually) 3 <br />$ /yr <br />5,500 <br />5,500 <br />5,500 <br />5500 <br />Miscellaneous R &R Costs 4 <br />$ /yr <br />12,000 <br />12,000 <br />6,000 <br />6,000 <br />Total Annual O &M Cost <br />$ /yr <br />20,891 <br />20,826 <br />14,891 <br />14,826 <br />Annual O &M Percentage of <br />Capital Cost <br />% <br />0.4 <br />0.3 <br />0.3 <br />0.2 <br />Notes: <br />1. 50Kw blower, 10 times, each time runs for 5 hours <br />2.40 Hours for O &M labor, Labor Hour + OT and tools is estimated to be $76.20/hr <br />3. 50% of LA County average debris cleaning cost <br />Source: http:// dpw. lacounty. gov/ epd /aboutthebag/pdf%5CDWAB_BC.pdf <br />4.
