110 <br />SEWER RATE STUDY I City of Santa Ana, CA <br />• CIP Project Identification: individual CIP projects identified based on high -risk assets and /or <br />assets that are in close proximity. Pipe segment identification, budgets and schedules often <br />differ from the previous lists due to logical regrouping of assets. For example, it makes more <br />sense to inspect or replace an entire continuous stretch of pipe even though the risk <br />prioritization may have scheduled specific segments to have been done at different times. <br />Therefore a single project will likely have segments with differing risk strategy group <br />assignments. <br />Note: risk prioritization and R &R replacement planning was based on existing data provided by the City. <br />Although the source data is believed to be the best available it may not reflect current conditions of all <br />facilities. Additionally, recent R &R activities may have already addressed some of the issues identified. <br />Therefore, recommendations should be verified with current R &R records and /or pipe inspection prior <br />to actual replacement or lining. <br />BRE REPLACEMENT PRIORITIZATION <br />Using the results of the BRE analysis and replacement costing table, each sewer main pipe segment was <br />ranked from highest to lowest risk and assigned a replacement cost estimate. A partial list (risk scores of <br />50 or higher) of sewer main pipeline segments ranked by BRE score is included in Table C 2 below. This <br />list includes the top 107 of the 8,706 total ranked records. <br />Table C - 2: Partial List of Sewer Main Pipe Segments Ranked by EIRE Score <br />I OBJECT SIZE YEAR LENGTH COHORT POE COF ESTIMATED <br />RANK ID MATERIAL (IN) INSTALLED DECADE (MILES) RANK SCORE SCORE BRE COST <br />1 <br />4091 <br />VCP <br />36 <br />1938 <br />1930s <br />0.08 <br />5 <br />10.0 <br />8.4 <br />84.0 <br />$200,608 <br />2 <br />4092 <br />VCP <br />36 <br />1938 <br />1930s <br />0.07 <br />5 <br />10.0 <br />8.4 <br />84.0 <br />$174,496 <br />3 <br />4418 <br />VCP <br />36 <br />1938 <br />1930s <br />0.13 <br />5 <br />10.0 <br />8.4 <br />84.0 <br />$313,555 <br />4 <br />4420 <br />VCP <br />36 <br />1938 <br />1930s <br />0.02 <br />5. <br />10.0 <br />8.4 <br />84.0 <br />$46,930 <br />5 <br />4422 <br />VCP <br />36 <br />1938 <br />1930s <br />0.07 <br />5 <br />10.0 <br />8.4 <br />84.0 <br />$177,184 <br />6 <br />4769 <br />VCP <br />36 <br />1938 <br />19305 <br />0.12 <br />5 <br />10.0 <br />8.4 <br />84.0 <br />$285,290 <br />7 <br />4770 <br />VCP <br />36 <br />1938 <br />1930s <br />0.16 <br />5 <br />10.0 <br />8.4 <br />84.0 <br />$374,400 <br />8 <br />4771 <br />VCP <br />36 <br />1938 <br />1930s <br />0.22 <br />5. <br />10.0 <br />8.4 <br />84.0 <br />$511,713 <br />9 <br />5596 <br />VCP <br />36 <br />1938 <br />1930s <br />0.06 <br />5 <br />10.0 <br />8.4 <br />84.0 <br />$136,812 <br />10 <br />5600 <br />VCP <br />36 <br />1938 <br />19305 <br />0.03 <br />5 <br />10.0 <br />8.4 <br />84.0 <br />$74,931 <br />11 <br />7486 <br />VCP <br />24 <br />0 <br />LINK <br />0.09 <br />4 <br />8.0 <br />7.6 <br />60.5 <br />$159,863 <br />12 <br />6966 <br />PCC <br />84 <br />1971 <br />19705 <br />0.19 <br />3 <br />6.0 <br />10.0 <br />60.0 <br />.$914,118 <br />13 <br />7985 <br />PCC <br />84 <br />1971 <br />1970s <br />0.22 <br />3 <br />6.0 <br />10.0 <br />60.0 <br />$1,073,723 <br />14 <br />3383 <br />VCP <br />6 <br />1927 <br />1930 Pre <br />0.04 <br />5 <br />10.0 <br />5.8 <br />58.4 <br />$35,352. <br />is <br />3964 <br />VCP <br />6 <br />1925 <br />1930 Pre <br />0.06 <br />5 <br />10.0 <br />5.8 <br />58.4 <br />$47,949 <br />16 <br />:7740 <br />VCP <br />6 <br />1927 <br />1930 Pre <br />0.03 <br />5 <br />10.0. <br />5.8 <br />58.4 <br />$24,820 <br />17 <br />3682 <br />PCC <br />48 <br />1958 <br />1950s <br />0.24 <br />3 <br />6.0 <br />9.2 <br />55.2 <br />$717,697 <br />18' <br />4144 <br />PCC <br />51 <br />1958 <br />1950s <br />0.24 <br />3 <br />6.0 <br />9.2 <br />55.2 <br />$738,326 <br />19 <br />6537 <br />PCC <br />42 <br />1952 <br />1950s <br />0.11 <br />3 <br />6.0 <br />9.2 <br />55.2 <br />$276,417 <br />65B -269 <br />NOVEMBER 2014 <br />
