City of Santa Ana, CA I SURER RATE STUDY <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. Table D 1 below is a <br />revised table (with the non -City owned mains removed) for all pipes having a BRE score of 50 or above. <br />The rank IDs were left as they were initially assigned to easily indicate which pipes were removed. <br />Table D -1: Partial List of Sewer Mains Ranked by BRE Score with Non -City owned Mains Removed <br />0. e <br />® ®®� • , ® •� •. e <br />ME ME ® M <br />1 <br />3383 <br />VCP <br />6 <br />1927 <br />1930 <br />0.04 <br />5 <br />10.0 <br />5.8 <br />58.4 <br />$35,352 <br />Pre <br />2 <br />3964 <br />VCP <br />6 <br />1925 <br />1930 <br />0.06 <br />5 <br />10.0 <br />5.8 <br />58.4 <br />$47,949 <br />Pre <br />3 <br />7740 <br />VCP <br />6 <br />1927 <br />1930 <br />0.03 <br />5 <br />10.0 <br />5.8 <br />58.4 <br />$24,820 <br />Pre <br />4 <br />2638 <br />VCP <br />6 <br />1929 <br />1930 <br />0.01 <br />5 <br />10.0 <br />5.0 <br />50.4 <br />$9,122 <br />Pre <br />5 <br />2840 <br />VCP <br />6 <br />1939. <br />19306 <br />0.07 <br />5 <br />10.0 <br />5.0 <br />50.4 <br />$60,187 <br />6 <br />3381 <br />VCP <br />6 <br />1939 <br />1930s <br />0.07 <br />5 <br />10.0 <br />5.0 <br />50.4 <br />$60,208 <br />7 <br />3382 <br />VCP <br />6 <br />1927 <br />1P9e0 <br />0.07 <br />5 <br />10.0 <br />5.0 <br />50.4 <br />$60,172 <br />8 <br />5745 <br />VCP <br />8 - <br />1927 <br />930 <br />0.01 <br />5 <br />10.0 <br />5.0 <br />50.4 <br />$10,068 <br />Pre <br />9 <br />1437 <br />VCP <br />30 <br />1969 <br />1960s <br />0.06 <br />3 <br />6.0 <br />8.4 <br />50.2 <br />$135,702 <br />10 <br />1438 <br />VCP <br />30 <br />1969 <br />1960s <br />0.03 <br />3 <br />6.0 <br />8.4 <br />50.2 <br />$66,034. <br />11 <br />1439 <br />VCP <br />27 <br />1969 <br />1960s <br />0.13 <br />3 <br />6.0 <br />8.4 <br />50.2 <br />$251,067 <br />R &R Strategy Groups and CIP Budgeting <br />The risk prioritization table just presented identifies pipe segments having the highest BRE score. Since <br />this score is based on the product of PoF times CoF factors, it gives equal consideration for both factors. <br />Typically, different R &R strategies are applied to address these two considerations. <br />Based on the BRE heat map graphic results, the ranked assets were then grouped into logical R &R <br />strategies. Figure D 4 shows the same BRE heat map graphic as before, but color coded by strategy <br />group. Table D 2 defines each of these groupings and provides additional summarizations and <br />recommendations. <br />BLACK & VEATCH I Appendix D: City -Owned Mains Ana!ysii <br />65B -286 <br />
