A <br /> AGGREGATE <br /> Mr.Martin Howell,President,Boyd Irrigation Company INDUSTRIES <br /> March 3.2006 <br /> Page Two <br /> accommodate flows greater than those historically conveyed through the property are costs to be <br /> borne either by the ditch company or the members of the ditch company who desire the <br /> improvement. <br /> It is my understanding that the City has assumed it had I 1 cfs to take out at the east end of the <br /> property based upon a 24-inch culvert pipe at the railroad bridge north of the Hill property. Upon <br /> that basis it has apparently been presumed that Al is responsible for a minimum 24-inch pipe. As <br /> noted above,the historic exit point is east of the railroad bridge and the size of the culverts would <br /> indicate that less than 11 cfs was taken out at that point. I believe that the 24-inch pipe upon <br /> which the City's 11 cfs delivery assumption has been made was pipe used for discharging water <br /> from the mine operation. <br /> It is AI's position that a 15-inch pipe is sufficient to carry the historical flow that the ditch on the <br /> F Street property carried. AI's cost for installing the 15-inch pipe is$40,636. This cost includes <br /> pipe bedding per bedding spec 6-inches over the 15-inch pipe, installation of three(3)4-foot <br /> manholes,and grouting and sealing to connect the pipe to the new outlet structure. Upgrading to <br /> a 24-inch pipe,requiring a minimum increase to 5-foot manholes and additional pipe bedding, <br /> increases the cost to$52,968. This cost again assumes a grout and seal pipe connection to the <br /> existing structure. Increasing the pipe to 30-inch,together with additional pipe bedding,6-foot <br /> manholes and the City's preferred 3-sided junction box connection to the existing structure <br /> increases the cost to$78,847. <br /> As soon as Al receives direction from the ditch company as to how to proceed,together with a <br /> written commitment from either the ditch company or the City of Greeley to reimburse to Al all <br /> costs associated with upgrades which exceed AI's share of responsibility in the amount of <br /> $40,636,Al will request that it's contractor order the materials and schedule completion of the <br /> work at the earliest possible date. <br /> I would be happy to meet with you on site regarding this matter,or if you have any questions or <br /> need additional information,please contact me at(970)336-6526. <br /> Very truly yours, <br /> e�", 0, G/ , <br /> Connie N.Davis <br /> Land Resources Assistant <br /> cc: Aggregate Industries-WCR,Inc.—File No. 35.15.08 <br /> Connie N.Davis,Land Resources <br /> P.O.Box 337231,Greeley,CO 80633 <br /> (970)336-6526 <br />
