Federal Emergency Management Agency Washington, D.C. 20472 JUL 232002 CERTIFIED MAIL RETURN RECEIPT REQUESTED IN REPLY REFER TO: Case No.: 02-08-185P The Honorable Michelle Lawrence Chairman, Jefferson County Board of Commissioners 100 Jefferson County Parkway Golden, CO 80419 Community: Jefferson County, CO Community No.: 080087 Panel Affected: 0165 B Effective Date of J U l 2 3. 2002 This Revision: 102-D-A Dear Ms. Lawrence: This responds to a request that the Federal Emergency Management Agency (FEMA) revise the effective Flood Insurance Rate Map (FIRM) and Flood Insurance Study (PIS) report for your community in accordance with Part 65 of the National Flood Insurance Program (NFIP) regulations. In a letter dated February 20, 2002, Mr. Dan Hartman, Director of Public Works, City of Golden, requested that FEMA revise the FIRM and FIS report to show the effects of channel modifications associated with the Ford Street bridge replacement along Clear Creek from approximately 120 feet downstream of the confluence with Tucker Gulch to approximately 1,850 feet upstream of Washington Avenue. The channel modifications included an enlarged bridge crossing at Ford Street, channel relocation, and grading. This request follows up on a Conditional Letter of Map Revision issued on May 20,1999. All data required to complete our review of this request were submitted with letters from Mr. Hartman and P.E., Senior Engineer, Anderson Consulting Engineers, Inc. We have completed our review of the submitted data and the flood data shown on the effective FIRM and in the effective PIS report. We have revised the FIRM and PIS report to modify the elevations and floodplain boundary delineations of the flood having a I-percent chance of being equaled or exceeded in any given year (base flood) along Clear Creek in your community from approximately 120 feet downstream to approximately 50 feet upstream of the confluence with Tucker Gulch. As a result of the modifications, the Base Flood Elevations (BFEs) for Clear Creek and the width of the Special Flood Hazard Area (SFHA), the area that would be inundated by the base flood, decreased. The modifications are shown on the enclosed annotated copies of PIRM Panel 0165 B and Profile Panel 84P. This Letter of Map Revision (LOMR) hereby revises the above-referenced panel of the effective FIRM dated August 5, 1986, and the affected portions of the PIS report dated July 4,1989. Because this revision request also affects the City of Golden, a separate LOMR for that community was issued on the same date as this LOMR. The modifications are effective as of the date shown above. The map panel listed above and as modified by this letter will be used for all flood insurance policies and renewals issued for your community.
