<br />included as part of Tables 4 and 6, and which have drainage areas equal to or greater than the <br />minimum drainage areas for their respective hydrologic Subregions but less than the maximwn <br />drainage areas for their respective hydrologic Subregions; and <br /> <br />WHEREAS, said new report includes approximate floodplain information for stream <br />reaches which lie within Arkansas River basin Subregion ARK-4a, as set forth in the <br />Guidelines, as included as part of Table 6, and which have drainage areas equal to or greater <br />than one-half (0.5) square mile but less than the minimwn drainage area for Subregion ARK-4a; <br />and <br /> <br />WHEREAS, the hydrology information for the approximate floodplains contained in <br />said new report for the stream reaches listed in Tables 4 and 6 which have drainage areas equal <br />to or larger than the lower limits and less than or equal to the upper limits for the use of the <br />Guidelines can been estimated in accordance with the Guidelines, for the purpose of Board <br />designation and approval, by utilizing the regression equation for Arkansas River basin <br />Subregion ARK-3 for those stream reaches in Subregion ARK-3 (Central Foothills Subregion) <br />and the regression equation for Arkansas River basin Subregion ARK-4a for those stream <br />reaches in Subregion ARK-4a (Northern Foothills Subregion; West of Monument Creek and <br />Fountain Creek); and <br /> <br />WHEREAS, the use of the U.s. Geological Survey publication, Techniques For <br />Estimating Regional Flood Characteristics of Stnilll Rural Watersheds in the Plains Region <br />of Eastern Colorado (Techniques) or any subsequent publication by the U.S. Geological <br />Survey which may supercede said puplication, for stream reaches that have drainage areas less <br />than the lower limits for the use of the Guidelines but larger than one-half (0.5) square mile in <br />the portions of the South Platte River basin generally below 8000 feet in elevation was endorsed <br />by the Guidelines; and <br /> <br />WHEREAS, the 100-year peak flows for all of the approximate stream reaches in <br />Arkansas River basin Subregion ARK-4a which <lI'e described in said new report and included <br />in Table 6 that have drainage areas less than the lower limits for the use of the Guidelines but <br />greater than one-half (0.5) square mile has beeIl estimated using the appropriate regression <br />equation in accordance with the U.S. Geological Survey Publication, Techniques; and <br /> <br />Approximate Stream Reaches Not Compliant with the Guidelines <br />WHEREAS, said new report includes approximate floodplain information for stream <br />reaches in Arkansas River basin Subregion ARK-3, as set forth in the Guidelines, within <br />unincorporated portions of Teller County as they were on September 30, 1988, as included as <br />part of Table 4, and which have drainage areas less than the minimum for Subregion ARK-3; <br />and <br /> <br />11 <br />
