~' Federal Emergency Management Agency Washington, D.C. 20+72 CERTIFIED MAIL RETURN RECEIPT REQUESTED IN REPLY REFER TO: Case No,: 95-08-104P The Honorable Bernard Dannels Mayor, Town of Estes Park P,O, BOll 1200 Estes Park, Colorado 80517 Community: Town of Estes Park, Colorado Community No,: 080193 Panel Affected: 0001 B Effective Date of This Revision: MAY 2 2 1995 102-I-C Dear Mayor Dannels: This is in response to a request for a revision to the effective National Flood Insurance Program (NFIP) map for your community. Specifically, this responds to a letter dated February 24, 1995, from Mr. John A, Spooner, P.E" Ph,D" Van Horn Engineering and Surveying, regarding the effective Flood Insurance Rate Map (FIRM) for the Town of Estes Park, Colorado, Mr, Spooner requested that we revise the effective FIRM to redelineate the floodplain and floodway boundaries of a flood having a I-percent probability of being equaled or ellceeded in any given year (base flood) along the Fall River using more up.to-date topographic data, In a letter dated April 24, 1995, Mr, John R, Alhnan, Floodplain Administrator. Town of Estes Park, indicated that the community is aware of the revision request and would adopt the requested floodplain and floodway, All data required to complete our review of this request were submitted with Mr, Spooner's February 24 letter and Mr, Allman's April 24 letter, Because this Letter of Map Revision (LOMR) solely incorporates more detailed information, fees were not assessed for the review, We have completed our review of the submitted data and the flood data shown on the effective FIRM. and have revised the FIRM to modify the floodplain and floodway boundary delineations of the base flood along the Fall River from just upstream to approllimately 370 feet upstream of Fish Hatchery Road, The hydraulic analyses performed for the effective Flood Insurance Study (FIS) were completed in April 1985, after the Lawn Lake Dam failure of July 1982, which changed the topography along the Fall River and the channel location, Although the hydraulic analyses were performed using surveyed cross sections that reflected the changes, the work map used to prepare the effective FIRM, dated June 1979, did not represent the ellisting topographic conditions, The width of the Special Flood Hazard Area (SFHA) has decreased from just upstream to approllimately 100 feet upstream of Fish Hatchery Road and has increased from approllimately 100 feet to approllimately 370 feet upstream of Fish Hatchery Road, The mallimum decrease in the width of the SFHA is approllimately 60 fee,t and occurs just upstream of Fish Hatchery Road, The maximum increase in the width of the SFHA is approllimately 50 feet and occurs approllimately 200 feet upstream of Fish Hatchery Road, The hydraulic analyses performed for the effective FIS show the floodway boundary delineation along this reach of the Fall River to coincide with the channel banks, The floodway has shifted a
