<br />. <br /> <br />. <br /> <br />, . <br /> <br />Floodine Problems and Floodine Historv <br />Flpqding problems in the lower Pawnee Creek basin can occur as a result of general rains over the <br />entire basin, or from local storms on individual tributaries to Pawnee Creek. An example of a <br />general rain occurred in June 1992, and intense thunderstorms occurred in May 1935, June 1965, <br />and July 29, 1997. <br /> <br />The 1935, 1965, and 1997 flood events caused major flood losses throughout the basin, In addition, <br />the flood events caused overflows, which entered the City of Sterling, and the community of <br />Atwood, Colorado, <br /> <br />1997 Flood Event <br />An account for the 1997 flood event is presented in a Colorado Water Conservation Board report <br />entitled "Pawnee Creek, Logan County, Colorado, Flood of July 1997," dated October 28, 1997, <br />The 1997 flood event is recorded as the "Flood-of-Record" at a number of locations within the <br />basin. The Pawnee Creek overflow into Sterling was greater in the June 1965 flood than in the <br />July 30, 1997 flood event. Local residents noted this observation. <br /> <br />Obiective <br />The Project objective is to develop a flood hazard mitigation feasibility study and prepare <br />portions of a final report to assist the local govemment (City of Sterling and Logan County) with <br />the preparation of a full application for the Hazard Mitigation Grant Program (HMGP), The <br />completed application with included technical information must satisfy all of the FEMA <br />requirements in order for the community to be eligible to receive federal grant money for project <br />implementation. For the purposes of this Project, Pawnee Creek watershed flood issues for <br />Sterling and Logan County will be addressed as two distinct components. The first component is <br />the Pawnee Creek Charmel Conveyance channel in Logan County which will be located on the <br />mainstem of Pawnee Creek near the community of Atwood, Colorado. The second component is <br />the Pawnee Creek Overflow in the vicinity of Sterling, Colorado. <br /> <br />Proiect Assienments <br />Study tasks will be divided among the Project participants as stated in the "Project Assignment" <br />outline of this Scope of Work. The attached "Report Outline" will be the basis for performing <br />the required work and completing the final Project report. The task assignments are summarized <br />in the table below, The term "local sponsor" refers to the City of Sterling and Logan County, <br />Colorado, <br /> <br />2 <br />
