The final step in determining the credit for Water Supply is to add up the following three <br /> components: <br /> Earned Credit <br /> Item Credit Available <br /> 616. Credit for Supply System (CSS) 35.00 35 <br /> 621. Credit for Hydrants (CH) 2.00 2 <br /> 631. Credit for Inspection and Condition (CIC) 2.40 3 <br /> Total Credit 39.40 40 <br /> If the score Orchid achieved for the water supply system was translated into a 100 point scale <br /> instead of the 40 points actually used, the relative Fire Suppression Rating Schedule <br /> classification for this section of the review would be a(relative) Class 1. <br /> Divergence <br /> Divergence considers a difference between the protection provided by the Fire Department <br /> and the Water Supply. This difference would prevent the better feature from being utilized to <br /> its fullest extent. Therefore, an adjustment is made to reflect any difference between these <br /> two features. Because of the difference in total weights assigned to the two features, the total <br /> for the Fire Department, which has the higher total weight, is adjusted to make the <br /> comparison reflect the relative adequacies of the two features. <br /> The expression b(CWS)-0.8(CFDA] in the following formula is the Divergence calculation: <br /> PPC = [ (CFA + CFD + CWS) - 0.5 (I (CWS) -0.8 (CFD) _]_ <br /> 10 <br /> PPC = C (9.35 + 28.36 + 39.40) - 0.5 {I (39.40) -0.8 (28.36) I) <br /> 10 <br /> ©ISO Properties,Inc.,2007 Page 34 <br /> 1LI'7 <br />
