A field review discovered that C -16 extends up the hill and receives flow from Ditch C -18. <br />The reclamation bond for C -16 is for a ninety foot length of pipe, which matches the culvert length that is <br />shown on Map 21 -1. Therefore, Map -20 was updated to be consistent with on the ground conditions and Map <br />21 -1. <br />It was discovered in the field that Culvert C -18 is a ditch. Therefore, the appropriate maps and tables have <br />been revised and a design summary sheet for new Ditch C26 is included. A reclamation bond credit of <br />$122.25 is attached. <br />A new ditch design summary sheet is included for Ditch B38 which is the ditch under the conveyor and <br />parallel to Culvert B -13. A bond increase is not necessary for new ditch B38 as the area is already included in <br />the regarding of the conveyor corridor. <br />Revised Pages, Volume III, Appendix 8: <br />Exh. 8 -29, 31, 58xii, 65i, 74viii(g), Reclamation Bond <br />Revised Maps Volume II: <br />15 -1, 15 -2, 21 -1, 21 -2, and 20 <br />Please feel free to contact me if you have any questions. <br />Sincerely, <br />�vrn� QC04 <br />Tamme Bishop, P.E. <br />Project Engineer <br />Cc..
