The channel <br />modifications included construction of a new regional detention facility upstream of Motsenbocker Road <br />and-the'channelization'and-relocation-of-Unnamed-Tributary_D_from_the_confluence_with_Chem Creek to <br />just downstream of Motsenbocker Road. This area is shown on the effective FIRM as a Special Flood <br />Hazard Area (SFHA), the area that would be inundated by the flood having a I-percent chance of being <br />equaled or exceeded in any given year (base flood), designated Zone A, where no Base Flood Elevations <br />have been detennined. This request follows up on a Conditional Letter of Map Revision issued on <br />September 7,2001. <br /> <br />All data required to complete our review of this request were submitted with letters from Mr. Michael <br />Hickey, P,E., Senior Project Engineer, and Mr. Justin Scholz, E.!., both with Carroll & Lange, Inc., and <br />Mr. Williams. <br /> <br />We have completed our review of the submitted data and the flood data shown on the effective FIRM. We <br />have revised the FIRM to modify the floodplain boundary delineations of the base flood along Unnamed <br />Tributary D. As a result of the modifications, the width of the SFHA for Unnamed Tributary D increased <br />in some areas and decreased in other areas_ The above-referenced channelized and relocated portion of <br />Unnamed Tributary D contains the base flood. The modifications are shown on the enclosed annotated <br />copy of FIRM Panel 0185 B. This Letter of Map Revision (LOMR) hereby revises the above-referenced <br />panel of the effective FIRM dated March 2,1993. <br /> <br />The modifications are effective as of the date shown above. The map panel listed above and as modified <br />by this letter will be used for all flood insurance policies and renewals issued for your community. <br /> <br />A review of the detennination made by this LOMR and any requests to alter this determination should be <br />made within 30 days. Any request to alter the determination must be based on scientific or technical data. <br />
