Box 1575 <br />Colorado Springs, CO 80901-1575 <br /> <br />Community: City of Colorado Springs, <br />Colorado <br />Community No.: 080060 <br />Panel Affected: 08041C0761 F <br />Effective Date of DEe 1'. 1999 <br />This Revision: "' <br /> <br />102-D-A <br /> <br />Dear Mayor Makepeace: <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 (FIS) report for EI Paso County, Colorado <br />and Incorporated Areas (the effective FIRM and FIS report for your community), in accordance with <br />Part 65 of the National Flood Insurance Program (NFIP) regulations. In a letter dated July 6, '1998, <br />Mr. Dan Bunting, Regional Floodplain Administrator, Pikes Peak Regional Building Department, requested <br />that FEMA revise the FIRM and FIS report to show the effects of channelization of Peterson Field <br />Drainage from approximately 900 feet upstream to approximately 6,500 feet upstream of Hancock <br />Expressway and construction of two 8-foot by 9-foot concrete box culverts under Powers Avenue <br />approximately 3,300 feet upstream of Hancock Expressway and two 8-foot by 9-foot concrete box culverts <br />under Zeppelin Drive approximately 5,200 feet upstream of Hancock Expressway. <br /> <br />All data required to complete our review of this request were submitted with letters from Mr. Michael A. <br />Chaves, Project Manager, Engineering Division, City of Colorado Springs; Mr. Ronald J. Sanchez, P.E., <br />Project Engineer, URS Greiner Woodward Clyde, Inc.; and Mr. Bunting. <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 />f100dway boundary delineations of the flood having a I-percent chance of being equaled or exceeded in <br />any given year (base flood) along the revised reach of Peterson Field Drainage from just upstream to <br />approximately 6,500 feet upstream of Hancock Expressway. As a result of the modifications, the base <br />flood elevations (BFEs) for the revised reach and the widths of the Special Flood Hazard Area (SFHA), <br />the area that would be inundated by the base flood, and the regulatory f100dway decreased. As a result <br />of the channelization, the base flood and the regulatory f100dway are contained in the engineered channel <br />from approximately 2,000 feet upstream to approximately 6,500 feet upstream of Hancock Expressway. <br /> <br />The modifications are shown on the enclosed annotated copies of FIRM Panel(s) 08041C0761 F, Profile <br />Panel(s) 177P and 178P, and affected portions of the Floodway Data Table. This Letter of Map Revision <br />(LOMR) hereby revises the above-referenced panel(s) of the effective FIRM and the affected portions of <br />the FIS report, both dated March 17, 1997, <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 /> <br />'- <br />
