Prepare cost estimate of recommended layouts. <br /> <br />Hydralogy <br /> <br />A detailed description of the hydrologic studies of the Niver Creek <br /> <br />basin is given in Chapter III of the Phase A report. The following is a summary <br /> <br />of that chapter and a description of the work performed under Phase B. <br /> <br />The Drainage Basin <br /> <br />The Niver Creek basin is located in the northern part of the Denver <br />metropolitan area; it extends from Federal Boulevard east to the South Platte <br />River, and from about 78th Avenue north to 100th Avenue. The major north- <br />south traffic artery, Interstate Highway 1-25, runs through the heart of the basin. <br />There are three municipalities, Federal Heights, Thornton and Adams County, in <br />the basin. A map of the basin boundaries is shown on Plate 11-1. <br /> <br />The basin boundaries on Plate II-I show the limits of the Niver Creek <br />drainage area. These boundaries were taken from the drainage basin descrip- <br />tions prepared for Project REUSE by the Denver Regional Council of Governments <br />and the Urban Drainage and Flood Control District. They were verified and ad- <br />justed slightly after field inspection. <br /> <br />11-2 <br />
