INTRODUCTION <br /> <br />Simons, Li & Associates, Inc. (SLA) is contracted by the Federal <br /> <br />Emergency Management Agency to perform flood insurance studies for the Town of <br /> <br /> <br />Estes Park and Larimer County, Colorado. A part of these studies is to <br /> <br /> <br />develop the peak flows for the 10-, SO-, 100- and SOO-year recurrence interval <br /> <br /> <br />floods for the streams in the study area. <br /> <br /> <br />A vicinity map is shown in Figure 1.1 which indicates the streams to be <br /> <br /> <br />studied. All of the streams are to be studied by detailed methods. Table 1.1 <br /> <br /> <br />lists the streams to be studied by community. The study length for each <br /> <br />stream is also included. <br /> <br />Other hydrologic studies are available for the study area. A review of <br /> <br />the existing studies and the methodologies used to determine flood frequency <br /> <br /> <br />curves was made in order to coordinate and check the quantities of flows. <br /> <br /> <br />The hydrologic analyses involved the collection and review of available <br /> <br /> <br />literature, collection and analysis of USGS gage records in the study areas, <br /> <br /> <br />comparison of the information, and selection of the peak flows for the spe- <br /> <br /> <br />cified recurrence interval floods. <br />
