.' Federal Emergency Management Agency Washington, D.C. 20472 CERTIFIED MAIL RETURN RECEIPT REQUESTED IN REPLY REFER TO: Case No.: 96-08-I7IP The Honorable David Ling Mayor, City of Rifle P,O, Box 1908 Rifle, Colorado 81650 Community: City of Ritle, Colorado Community No.: 085078 Panels Affected: 1352 D and 1352 Effective Date of This Revision: MAY 3 1 1996 102-I-A-C Dear Mayor Ling: This responds to a request for a revision to the effective Flood Insurance Study (FIS) and National Flood Insurance Program (NFIP) map for your community. Specifically, this responds to a facsimile dated May 8, 1996, from Ms. Leslie A. Hope, E,I., Project Engineer, High Country Engineering, Inc., regarding the effective FIS report, Flood Insurance Rate Map (FIRM), and Flood Boundary and Floodway Map (FBFM) for the City of Rifle, Colorado, With her facsimile, Ms. Hope provided additional information to support her March 14, 1996, request for a Letter of Map Revision (LOMR). Ms. Hope requested that the Federal Emergency Management Agency (FEMA) revise the effective FIRM and FBFM to show the effects of updated, more detailed topographic information along Ritle Creek Splittlow. All data required to complete our review of this request were submitted with Ms. Hope's March 14 letter and her May 8 facsimile. Because this LOMR solely incorporates more detailed information, fees were not assessed for the review. We have completed our review of the submitted data and the tlood data shown on the effective FIRM and FBFM, and have revised the FIRM and FBFM to modify the elevations and tloodplain and tloodway boundary delineations of a tlood having a I-percent chance of being equaled or exceeded in any given year (base flood) along Ritle Creek Splittlow from its contluence with Ritle Creek to the City of Ritle's corporate limits at County Road 291 and along Ritle Creek from approximately 2,600 feet upstream of Old Creek Meadows Bridge to approximately 1,350 feet downstream of County Road 291, This revision incorporates updated topographic information retlecting changes in the tloodplain that occurred before January 3,1986, the date of the effective FIRM, FBFM, and FIS, These data show that the tlowpath of the base tlood along Ritle Creek Splittlow has changed, shifting the contluence with Ritle Creek upstream of the contluence shown on the effective FIRM and FBFM, The new data also show that tlow no longer splits from the east bank of Ritle Creek Splitflow just upstream of 30th Street. Ritle Creek Splittlow now rejoins Ritle Creek at one location.
