In a letter dated August 18, 1999, <br />Mr. Bill DeGroot, P.E., Chief, Floodplain Management Program, Urban Drainage and Flood Control <br />District, requested that FEMA revise the FIRM and FIS report to show the effects of construction along <br />Big Dry Creek of major drainageway features that consist of bank protection, grade-control structures, <br />crossing structures, and detention facilities, including Pond 10 just upstream of South University <br />Boulevard, and revised hydrologic and hydraulic analyses for Big Dry Creek Tributary A and Big Dry <br />Creek Tributary C. <br /> <br />All data required to complete our review of tms request were submitted with letters from Mr. DeGroot and <br />P.E., Project Manager, WRC Engineering, Inc. <br /> <br />We have completed our review of the submitted data and the flood data shown on the effective FIRM and <br />FIS report. We have revised the FIRM and FIS report to modify the elevations and floodplain and <br />floodway boundary delineations of the flaxi having a I-percent chance of being equaled or exceeded in <br />any given year (base flood) along Big Dry Creek from the confluence with the South Platte River to <br />approximately 550 feet downstream of South Santa Fe Drive; fromjust upstream of South Windermere <br />Street to just downstream of East Belleview Avenue; from approximately 1,050 feet downstream to <br />approximately 700 feet downstream of Lehow Avenue; from just downstream to just upstream of Lehow <br />Avenue; and from approximately 700 feet upstream of Lehow Avenue to approximately 1,050 feet <br />downstream of East Powers Avenue. As a result of the modifications, the base flood elevations (BFEs) <br />for Big Dry Creek and the widths of the Special Flood Hazard Area (SFHA), the area that would be <br />inundated by the base flood, and the regulatory floodway increased in some areas and decreased in other <br />areas. The modifications are shown on the enclosed annotated copies of FIRM Panel(s) 08005C0145 J, <br />08005C0165 J, 08005C0435 J, and 08005C0455 J; Profile Panel(s) 03P through 06P; and affected portions <br />
