<br />- <br /> <br />City and County of Denver, Colorado <br />Description of Revision <br /> <br />This study was revised to incorporate a Letter of Map Revision (LOMR) dated January 8, 1997, which revised <br />the base flood elevations (BFEs) and floodplain boundaries along Goldsmith Gulch, South Monaco Street <br />Parkway Overflow, Cherry Creek, and Southmoor Park Tributary. The floodway boundaries along Goldsmith <br />Gulch and South Monaco Street Parkway were also modified as part of the LOMR. This revision supersedes <br />the results described in Section 10.1 of the Flood Insurance Study report. <br /> <br />The modifications to the BFEs and floodplain boundaries along the aforementioned flooding sources are a <br />result of the construction of Phase III of the Goldsmith Gulch Flood Control Project. Phase III of this project <br />includes construction of the Florida"South Monaco Street Parkway Storm Sewer System, channel and culvert <br />construction and improvements, construction of an earthen berm at Bible Park, and construction of a detention <br />pond at the corner oflliff Avenue and South Monaco Street Parkway. The improvements affect the reach of <br />Goldsmith Gulch from its confluence with Cherry Creek to just upstream of Belleview Avenue. <br /> <br />As result of the construction of the project, the BFEs for Goldsmith Gulch increased in some areas and <br />decreased in other areas and the widths of the Special Flood Hazard Area (SFHA) and regulatory floodway <br />increased in some areas and decreased in other areas. The BFEs along South Monaco Street Parkway <br />decreased. The widfus of the SFHA and regulatory floodway increased and decreased throughout the revised <br />reach. The reduction in the base flood discharge resulted in decreases in the BFEs along the revised reach of <br />Cherry Creek. The width of the SFHA along Cherry Creek decreased from approximately 50 feet upstream <br />to approximately 1,200 feet upstream of South Holly Street, where backwater from Cherry Creek affects the <br />area in the vicinity of Minnesota Drive. <br /> <br />The modifications are shown on Flood Insurance Rate Map Panels 0019 E, 0020 E, 0024 E, and 0025 E and <br />Profile Panels lOP, llP, 53P, 54P, 55P, and 99P through 107P and in the Summary of Discharges and <br />Floodway Data Tables. <br />
