<br /> <br />Federal Emergency Management Agency <br />Washington, D.C. 20472 <br /> <br />CERTIFIED MAIL <br />RETURN RECEIPT REQUESTED <br /> <br />IN REPLY REFER TO: <br />Case No.: 99c08"192P <br /> <br />The Honorable Steve Ward <br />Chairman, Arapahoe County <br />Board of Commissioners <br />5334 South Prince Street <br />Littleton, CO 80166 <br /> <br />Community: Arapahoe County, Colorado <br />Community No.: 080011 <br />Panel Affected: 08OO5C0345 J <br />Effective Date of 0 CT 1 2 1999 <br />This Revision: <br /> <br />102-D-A <br /> <br />Dear Mr. Ward: <br /> <br />This responds to a request that the Federal Emergency Management Agency (FEMA) revise the effective <br />Flood Insurance Rate Map (FIRM) and Flood Insurance Study (PIS) report for Arapahoe County, Colorado <br />and Incorporated Areas (the effective FIRM and PIS report for your community), in accordance with <br />Part 65 of the National Flood Insurance Program (NFIP) regulations. In a letter dated February 24, 1999, <br />Mr. Richard M. Romberg, P.E., Lane Engineering Service, Inc., requested that FEMA revise the FIRM <br />and PIS report to show the effects of channel improvements along Dutch Creek that included construction <br />of a four-cell concrete box culvert at Platte Canyon Road. This request follows up on a Conditional Letter <br />of Map Revision issued on July 23, 1996. <br /> <br />All data required to complete our review of this request were submitted with letters from Mr. Romberg. <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 boundary <br />delineations of the flood having a I-percent chance of being equaled or exceeded in any given year (base <br />flood) along Dutch Creek from Platte Canyon Road to approximately 2,400 feet upstream. As a result of <br />the modifications, the base flood elevations (BFEs) for the revised reach and the width of the Special Flood <br />Hazard Area (SFHA), the area that would be inundated by the base flood, decreased. The modifications <br />are shown on the enclosed annotated copies of FIRM Panel(s) 08OO5C0435 J and Profile Panel(s) 55P. <br />This Letter of Map Revision (LOMR) hereby revises the above-referenced panel(s) of the effective FIRM <br />and the affected portions of the FIS report, both dated August 16, 1995. <br /> <br />Because this revision request also affects the Town of Columbine Valley, a separate LOMR for that <br />community was issued on the same date as this LOMR. <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 />
