3 <br />8. The parties recognized that the map <br />described in section (b) of the preceding <br />paragraph does not represent an engineered <br />design. The Division agrees to implement the <br />drainage pattern contained in the map usincx <br />We recognize that the cost of the revised work in the West Pit may <br />very well exceed the $18,500 provided by Harrison-Western. If <br />necessary, the additional funds will be allocated from the GEC bond <br />funds. I understand that you do not agree with the expenditure of <br />GEC funds for work in the West Pit. However, if the West Pit work <br />is to be completed, the only two available options are to construct <br />the cross-slope drainage as proposed in the existing bid document <br />(at an estimated cost of $33,000) or to remove the pond and route <br />the drainage directly into Magpie Creek. <br />I hope you will agree that the new plan appears to have a much <br />greater chance of successfully passing runoff from large storm <br />events as have occurred in recent years in the GEC area. The <br />original plan calls for a twelve foot wide, two foot deep <br />trapezoidal ditch running across slope for over 700 feet with 15" <br />diameter riprap. The new plan calls for a twenty foot wide, 2.75 <br />foot deep trapezoidal ditch following existing drainage contours <br />with 9 inch diameter riprap. Based upon the more natural <br />configuration and the documentation of the design parameters, the <br />staff is confident that the new design is more appropriate than the <br />original plan. <br />to perform the work. <br />
