4 . . . .~ Federal Emergency Management Agency Washington, D.C. 20472 MAR 1 2 2001 CERTIFIED MAIL RETURN RECEIPT REQUESTED IN REPLY REFER TO: Case No.: 01-08-067R The Honorable Steve Burkholder Mayor, City of Lakewood 480 South Allison Parkway Lakewood, CO 80226-3127 Community: City of Lake wood, CO Community No.: 085075 104 Dear Mayor Burkholder: This responds to a request that the Federal Emergency Management Agency (FEMA) comment on the effects that a proposed project would have on the effective Flood Insurance Rate Map (FIRM) and Flood Insurance Study (FIS) report for your community in accordance with Part 65 of the National Flood Insurance Program (NFIP) regulations. In a letter dated October 10, 2000, Mr. Bruce Behrer Jr" P.E., Project Manager, Muller Engineering Company, Inc., requested that FEMA evaluate the effects that more detailed topographic information along Bear Creek from approximately 75 feet downstream to approximately 450 feet upstream of Estes Street and proposed redevelopment on the LAGO property along the northern overbank of Bear Creek from approximately 150 feet upstream to approximately 1,350 feet upstream of Estes Street would have on the flood hazard information shown on the effective FIRM and FIS report. The Special Flood Hazard Area (SFHA), the area that would be inundated by the flood having a I-percent chance of being equaled or exceeded in any given year (base flood), along these reaches is designated Zone A, an SFHA with no Base Flood Elevations determined. All data required to complete our review of this request for a Conditional Letter of Map Revision (CLOMR) were submitted with letters from Mr. Behrer. The effective FIRM previously was revised by a Letter of Map Revision (LOMR) that became effective on October 27, 2000, to correct the SFHA along Bear Creek from just downstream to approximately 1,300 feet upstream of Estes Street. We reviewed the submitted data and the data used to prepare the effective FIRM for your community and determined that the proposed project meets the minimum floodplain management criteria ofthe NFIP. The submitted existing conditions HEC-2 hydraulic computer model, dated October 5, 2000, based on updated topographic information, was used as the base conditions model in our review ofthe proposed conditions model for this CLOMR request. We believe that, if the proposed project is constructed as shown on the submitted topographic work map entitled "Lago Property, Floodplain Delineation Plan, Sheet 2 00," prepared by Muller Engineering Co., Inc., dated October 10, 2000, and the data listed below are received, a revision to the FIRM would be warranted. As a result of the more detailed topographic information, the existing conditions base flood water-surface elevations (WSELs) along Bear Creek decreased compared to the effective base flood WSELs. The maximum decrease in base flood WSEL, 0.1 foot, occurred approximately 650 feet upstream of Estes Street.
