lis <br />WATER RATE STUDY I City of Santa Ana, CA <br />Table B -10: Summary of CoF Criteria used in this Study <br />By applying the weighting described above (100% Diameter, 0% Critical Locations) to each of the 21,477 <br />active main pipeline segments in the Santa Ana Water System, a 1 to 10 CoF Score was calculated for <br />each, with the distribution shown in Figure B - 30. Figure B - 31 provides a map of water mains color <br />coded by total CoF score. <br />Figure B - 30: Distribution of Water Pipeline CoF Scores <br />65B -130 <br />NOVEMBER 2014 <br />Pipe Diameter <br />100% <br />Assigned values 0 -10 <br />= <4" assigned score of 0 16" assigned score of 6 <br />range <br />6" assigned score of 1 18" assigned score of 7 <br />8" assigned score of 2 20" assigned score of 8 <br />10" assigned score of 3 24 - 30" assigned score of 9 <br />12" assigned score of 4 36 -78" assigned score of 10 <br />14" assigned score of S <br />Critical <br />n/a <br />Additive: based on <br />2 critical customers within 300 feet of pipe: Increase CoF by 2 <br />Customer <br />assumption that <br />1 critical customer within 300 feet of pipe: Increase CoF by 1 <br />Impact <br />No critical customers within 300 feet of pipe: CoF is based solely on <br />diameter score <br />Total (sum of <br />100% <br />The resulting CoF <br />Total CoF score not to exceed 10 <br />above) <br />scores are 0 to 10. <br />By applying the weighting described above (100% Diameter, 0% Critical Locations) to each of the 21,477 <br />active main pipeline segments in the Santa Ana Water System, a 1 to 10 CoF Score was calculated for <br />each, with the distribution shown in Figure B - 30.
