Box 17 <br />Black Hawk, Colorado 80422 <br /> <br />Community: ICity"ol',Black HaWk,colorado <br />Community No.: 080076 <br />FIRM Panel Affected:!iiOOOl B' <br />FBFM Panel Affected: \100011 <br />Ef~ective.~ate of NOY 0 9 1998 <br />Thts RevIsIon: <br /> <br />102-I-A-C <br /> <br />Dear Mayor Eccker: <br /> <br />This responds to a request that the Federal Emergency Management Agency (FEMA) revise the effective <br />Flood Insurance Rate Map (FIRM), Flood Boundary and Floodway Map (FBFM), and Flood Insurance <br />Study (FIS) report for your community in accordance with Part 65 of the National Flood Insurance <br />Program (NFIP) regulations. In a letter dated May 19, 1998, Mr. Lawrence E. Dezman, P.E., Vice <br />President, Futura Engineering Inc., requested that FEMA revise the FIRM, FBFM, and FIS report to show <br />the effects of several projects associated with construction of a hotel/casino between North Clear Creek <br />and Main Street. The projects consist of culvert construction under Richman Street between State <br />Highway 119 and Main Street, channelization of North Clear Creek from approximately 1,120 feet <br />downstream to approximately 1,620 feet downstream of Gregory Street, construction of an 8-foot-diameter <br />bypass pipe that parallels the entire length of the channelization project, and construction of an inlet <br />structure at the upstream end of the bypass pipe and channelization project. The entire revised reach <br />extends from approximately 550 feet downstream to approximately 2,050 feet downstream of Gregory <br />Street. This request follows up on a Conditional Letter of Map Revision issued on December 13, 1996. <br /> <br />All data required to complete our review of this request were submitted with letters from Mr. Dezman and <br />Mr. Jon Gray, Design Engineer, also with Futura Engineering Inc. <br /> <br />We have completed our review of the submitted data and the flood data shown on the effective FIRM; <br />FBFM, and FIS report. We have revised the FIRM, FBFM, and FIS report to modify the elevations and <br />floodplain boundary delineations of the flood having a I-percent chance of being equaled or exceeded in <br />any given year (base flood) along North Clear Creek from approximately 550 feet downstream to <br />approximately 2,050 feet downstream of Gregory Street. As a result of the modifications, the base flood <br />elevations (BFEs) for North Clear Creek increased, and the width of the Special Flood Hazard Area <br />(SFHA), the area that would be inundated by the base flood, decreased. The increased BFEs are contained <br />within the channelized portion of North Clear Creek. The modifications are shown on the enclosed <br />annotated copies of FIRM Panel(s) 0001 B, FBFM Panel(s) 0001, Profile Panel(s) 02P and 03P, and <br />affected portions of the Floodway Data Table. The FBFM has also been revised to show the cross-section <br />location modifications. This Letter of Map Revision (LOMR) hereby revises the above-referenced panel(s) <br />of the effective FIRM and FBFM dated October 16, 1984, and the affected portions of the FIS report dated <br />April 16, 1984. <br /> <br />The modifications are effective as of the date shown above. The map panel(s) as listed above and as <br />modified by this letter will be used for all flood insurance policies and renewals issued for your community. <br />
