SECTION II <br />DRAINAGE AREA <br />GENERAL <br />The specific drainage area designated for detail study lies west of <br />Greeley between 23rd Avenue and 35th Avenue and runs from 28th Street on the <br />south to the Cache La Poudre River on the north. However, proper evaluation <br />of a specific drainage area, requires a detailed analysis of all drainage <br />basins feeding into the specific area and a study of the channel or channels <br />Into which the run -off is discharged. <br />To accomplish the required drainage study, all contributing drainage <br />basins to the south and west of Greeley were thoroughly investigated. In <br />addition, the effect of this discharge into Greeley Ditch No. 3 and the <br />drainage channels leading to the Cache La Poudre River was studied. This <br />expanded drainage area extends from near 14th Avenue on the east to 51st <br />Avenue on the west, and from the Greeley Loveland Ditch near 28th Street on <br />the south, to the Cache La Poudre River on the north. <br />The natural slope of the land is northeast from a ridge south and west <br />of Greeley to the river on the north and east of the City. The Greeley - <br />Loveland Ditch and its lateral, the Grapevine Ditch, follow the ridge on the <br />south and west and form the upper boundary of the drainage basin. Across the <br />north end of the drainage basin, the Greeley No. 3 Ditch flows from west to <br />east closely paralleling the Cache La Poudre River. In addition to Greeley <br />Ditch No. 3, several streets, avenues, and ditch laterals intercept the <br />natural slope and act as boundaries for small drainage areas within the large <br />natural basins. <br />- 5 - <br />
