Federal Emergency Management Agency Washington, D.C. 20472 CERTIFIED MAIL RETURN RECEIPT REQUESTED IN REPLY REFER TO: Case No!;"Q7c08c363P The Honorable Linda Morton Mayor, City of Lakewood 445 South Allison Parkway Lakewood, Colorado 80226-3105 Community: ,!,City of Lakewood, Colorad~ Community No.: 085075 Panel Affected: 0005C, Ef~ective.~ate of SEP2 it 1998 This RevIsIOn: · 102-I-A-C Dear Mayor Morton: 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 August 4, 1997, Mr. Michael S. Dungan, P.E., Project Manager, Muller Engineering Company, Inc., requested that FEMA revise the FIRM to show the effects of the O'Kane Park and Benton Street detention ponds, channelization, a pipe system from Harlan Street to Kendall Street, and an updated hydraulic model along First Avenue Tributary to Weir Gulch. All data required to complete our review of this request were submitted with letters from Mr. Bill DeGroot, P.E., Chief, Floodplain Management Program, Urban Drainage and Flood Control District, and Mr. Dungan. We have completed our review of the submitted data and the flood data shown on the effective FIRM. We have revised the FIRM 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 First Avenue Tributary to Weir Gulch. As a result of the modifications, the base flood elevations (BFEs) for First A venue Tributary to Weir Gulch increased in some areas and decreased in other areas, and the width of the Special Flood Hazard Area (SFHA), the area that would be inundated by the base flood, increased in some areas and decreased in other areas. The increase in SFHA width from just upstream to approximately 500 feet upstream of Newland Street and from just downstream to approximately 700 feet downstream of Depew Street is contained in the O'Kane Park and Benton Street detention ponds, respectively. The shift in SFHA delineations and increase in BFE approximately 400 feet downstream of Newland Street is a result of updated information. The shift in SFHA delineations approximately 400 feet upstream of Sheridan Boulevard is also a result of updated information. The modifications are shown on the enclosed annotated copy of FIRM Panel(s) 0005 C. This Letter of Map Revision (LOMR) hereby revises the above-referenced panel(s) of the effective FIRM dated January 3, 1983. 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.
