<br />1'-1'- <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />i I <br /> <br />1623.001 <br /> <br />Report Summary #5 <br /> <br />"Interim Flood Hydrology Report" <br />by Resource Consultants, Inc. <br />Prepared in October, 1977 <br /> <br />The purpose of this report was to summarize recent hydrologic <br />investigations in the Spring Creek watershed. These investigations <br />were conducted primarily to estimate the potential 100-year flood <br />flows, with and without importation of water through existing canal <br />systems, at selected points along Spring Creek below Moore Park. <br />This interim report was developed for the purpose of floodway planning <br />on Spring Creek during the interim period until a final storm water <br />management plan could be developed. <br /> <br />Previous hydrologic studies, done in conjunction with the analysis of <br />the proposed Moore Park detention structure did not consider potential <br />flood flows below this location on Spring Creek. This study considers <br />flood flows at four specific points below the proposed Moore Park <br />detention structure. <br /> <br />1. Colorado and Southern Railroad crossing west of College Avenue <br /> <br />2. Stover Street bridge <br /> <br />3. Lemay Avenue bridge <br /> <br />4. Point where Timberline Road crosses Spring Creek <br /> <br />The Colorado Urban Hydrograph Procedure (CUHP) was used, incorporating <br />rainfall patterns and watershed characteristics to generate anticipated <br />runoff hydrographs. There are no stream-gaging stations in the basin <br />or on other similar streams in the general vicinity. Rainfa11-intensity- <br />duration curves used in this report were developed by Land and Water <br />Consultants for the Moore Park Study. The curves were prepared from <br />Colorado precipitation data published by the National Oceanic and <br />Atmospheric Administration. <br />
