A verbal request was presented at the April 23, 2009 GLWMO meeting when <br />the final draft Lake Owasso UAA report was presented to the Board. The Board requested that a written <br />budget amendment request be prepared at their April 2009 regular meeting. The request for addition project <br />budget is primarily related to the following: <br />I }Unforeseen calibration issues with the runoff and pollutant loading models and the in-lake water <br />quality models, <br />2) Additional reporting as the result of the additional calibration and modeling performed, and <br />3} Preparation for and attendance of several unbudgeted meetings <br />Details for each of the items above are outlined in Attachment A. The additional work and unanticipated <br />items are organized by the project task they were associated with in both the original project scope as well <br />as in the 200$ scope extension. <br />Attachment B shows the Lake Owasso UAA Budget Performance, tracking the budget at each of the invoice <br />dates, as well as providing a description of the major casks occurring during each time period. Also shown <br />on this figure are the meetings that were attended. This includes the GLWMO quarterly meetings, lake <br />association meetings, and "other" meetings which inc]ude an unplanned lake user survey stakeholder <br />meeting and an unplanned field survey of direct discharges to the lake with lake residents and RWMWb. <br />Ban Engineering Co. is requesting that the GLWMO board consider authorizing a cost increase for the <br />additional scope of services listed above of $41,125. <br />Sincerely, <br />Henry M. {Ha!)
