Federal Emergency Management Agency Washington, D.C. 20472 CERTIFIED MAIL RETURN RECEIPT REQUESTED IN REPLY REFER TO: Case No.: 99-08-035P The Honorable Victor F. Smith Mayor, Town of Erie 645 Holbrook Street Erie, Colorado 80516-0100 Community: Town of Erie, Colorado Community No.: 080181 Panel Affected: 0001 D Ef~ective. ~ate of,!" OW 1 6 1998 This ReVISion: 102-I-C Dear Mayor Smith: This responds to a request that the Federal Emergency Management Agency (FEMA) revise the effective Flood Insurance Rate Map (FIRM) for your community in accordance with Part 65 of the National Flood Insurance Program (NFIP) regulations. In a letter dated October 19, 1998, Ms. Wendi Palmer, Construction Engineer, Public Works Department, Town of Erie, requested that FEMA revise the FIRM to correct a mapping error. A Letter of Map Revision (LOMR) was issued on May 24, 1996, to show the effects of construction of levees and channelization along Coal Creek from approximately 3,600 feet downstream to approximately 600 feet upstream of the Union Pacific Railroad (UPRR). However, the revised floodplain and flood way boundary delineations of the flood having a I-percent chance of being equaled or exceeded in any given year (base flood) were shown incorrectly on the annotated copy of the FIRM accompanying the May 24 LOMR. All data required to complete our review of this request were submitted with letters from Ms. Palmer. Because this LOMR is being issued to correct a mapping or study analysis error, 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. ~ have revised the FIRM to modify the floodplain and floodway boundary delineations of the base flood along Coal Creek from the southern corporate limit at the UPRR to approximately 1,850 feet downstream. As a result of the modifications, the floodplain and floodway boundary delineations for Coal Creek shifted to the east. The maximum shift, approximately 100 feet, occurred adjacent to Anderson Street. The modifications are shown on the enclosed annotated copy of FIRM Panel(s) 0001 D. This LOMR hereby revises the above-referenced panel(s) of the effective FIRM dated September 28, 1990. The May 24 LOMR also affected Weld County, but this revision does not extend beyond the corporate limit of the Town of Erie. Therefore, the May 24 LOMR issued for Weld County is still valid. The modifications are effective as of the date shown above. The map panel(s) as listed above and as modified by this letter will be used for all flood insurance policies and renewals issued for your community. A review of the determination made by this LOMR and any requests to alter this determination should be made within 30 days. Any request to alter the determination must be based on scientific or technical data.
