Greenlee <br />Mayor, City of Boulder <br />P.O. Box 791 <br />Boulder, CO 80306 <br /> <br />Community: City of Boulder, Colorado <br />Community No.: 080024 <br />Panel Affected: 08013C0395 F <br />E~ective. ~ate of J U l 0 1 1999 <br />This ReVISIon: <br /> <br />102-I-C <br /> <br />Dear Mayor Greenlee: <br /> <br />This responds to a request that the Federal Emergency Management Agency (FEMA) revise the effective <br />Flood Insurance Rate Map (FIRM) for Boulder County, Colorado and Incorporated Areas (the effective <br />FIRM for your community), in accordance with Part 65 of the National Flood Insurance Program (NFIP) <br />regulations. In a letter dated April 20, 1999, Mr. Alan Taylor, P.E., Floodplain and Wetlands <br />Coordinator, Department of Public Works, City of Boulder, requested that FEMA revise the FIRM to <br />correct mapping errors along Farmers Ditch and Fourmile Canyon Creek. <br /> <br />All data required to complete our review of this request were submitted with letters from Mr. Taylor. <br />Because this Letter of Map Revision (LOMR) is being issued to correct a mapping or study analysis error, <br />fees were not assessed for the review. <br /> <br />We have completed our review of the submitted data and the flood data shown on the effective FIRM. We <br />have revised the FIRM to modify the floodplain boundary delineations of the flood having a I-percent <br />chance of being equaled or exceeded in any given year (base flood) along Farmers Ditch and Fourmile <br />Canyon Creek. As a result of the modifications, the width of the Special Flood Hazard Area (SFHA), the <br />area that would be inundated by the base flood, for Farmers Ditch increased in the area between Fourmile <br />Canyon Creek and Wonderland Creek. The SFHA in this area is approximately 40 feet wide and is too <br />narrow to be shown to scale on the effective FIRM. With this revision, the stream centerline delineation <br />for Farmers Ditch shifted approximately 80 feet southeast. We have also revised the FIRM to correct the <br />SFHA boundary delineations along Fourmile Canyon Creek approximately 200 feet upstream of <br />28th Street. As a result of this modification, the width of the SFHA along Fourmile Canyon Creek <br />decreased. The modifications are shown on the enclosed annotated copy of FIRM Panel(s) 08013C0395 F. <br />This LOMR hereby revises the above-referenced panel(s) of the effective FIRM dated June 2, 1995. <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 />A review of the determination made by this LOMR and any requests to alter this determination should be <br />made within 30 days. Any request to alter the determination must be based on scientific or technical data. <br /> <br />We will not physically revise and republish the FIRM and Flood Insurance Study (FIS) report for your <br />community to reflect the modifications made by this LOMR at this time. When changes to the previously <br />cited FIRM panel(s) and FIS report warrant physical revision and republication in the future, we will <br />incorporate the modifications made by this LOMR at that time.
