In a letter dated September 11, 1995, <br />Mr. Fred G. Tafoya III, P.E., Project Manager, Kirkham Michael Consulting Engineers, requested that <br />FEMA revise the FIRM and PIS report to show the effects of a modified channel and culvert along <br />Goldsmith Gulch associated with the Copper Terrace apartment project. This request follows up on a <br />Conditional Letter of Map Revision issued on April 25, 1996. <br /> <br />All data required to complete our review of this request were submitted with letters from Mr. Tafoya. <br /> <br />We have completed our review of the submitted data and the flood data shown on the effective PIRM and <br />FIS report. We have revised the FIRM and FIS report to modify the elevations and floodplain boundary <br />delineations of the flood having a I-percent chance of being equaled or exceeded in any given year (base <br />flood) along Goldsmith Gulch from approximately 150 feet downstream of East Peakview Avenue to just <br />downstream of East Arapahoe Road. As a result of the modifications, the base flood elevations (BFEs) for <br />the revised reach and the width of the Special Flood Hazard Area (SFHA), the area that would be <br />inundated by the base flood, increased in some areas and decreased in other areas. The base flood will be <br />contained in the engineered channel from approximately 400 feet upstream of East Peakview Avenue to <br />just downstream of East Arapahoe Road. The modifications are shown on the enclosed annotated copies <br />of FIRM Panel(s) OS005C0480 J, ProftIe Panel(s) 69P, and affected portions of the Floodway Data Table. <br />This Letter of Map Revision (LOMR) hereby revises the above-referenced panel(s) of the effective FIRM <br />and the affected portions of the FIS report, both dated August 16, 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 />The following table is a partial listing of existing and modified BFEs: <br /> <br />Location <br /> <br />Existing BFE <br />(feet)* <br /> <br />Modified BFE <br />(feet)* <br /> <br />Approximately 130 feet downstream of East Peakview <br />Avenue <br />Approximately 400 feet upstream of East Peakview <br />Avenue <br /> <br />5,733 <br /> <br />5,734 <br /> <br />5,748 <br /> <br />5,742 <br /> <br />*Referenced to the National Geodetic Vertical Datum, rounded to the nearest whole foot <br />
