<br />- <br />r <br /> <br />2 <br /> <br />The base flood elevations (BFEs) decreased along the affected portion of Rifle Creek Splitflow from the <br />City of Rifle, Colorado's corporate limits, at County Road 291, to approximately 200 feet downstream <br />of the divergence of Rifle Creek Splitflow from Rifle Creek. The maximum decrease in BFE, 4 feet, <br />occurred just downstream of County Road 291. The Special Flood Hazard Area (SFHA) width increased <br />and decreased along Rifle Creek Splitflow and its boundary delineations shifted approximately 100 feet <br />south of the SFHA shown on the effective FIRM and FBFM. The maximum decrease in SFHA width, <br />approximately 150 feet, occurred approximately 300 feet downstream of the divergence of Rifle Creek <br />Splitflow from Rifle Creek. The maximum increase in SFHA width, 300 feet, occurred just upstream <br />of County Road 291. The floodway width increased and decreased along the entire reach of Rifle Creek <br />Splitflow. The maximum increase in floodway width, approximately 150 feet, occurred just upstream of <br />County Road 291. The maximum decrease in floodway width, approximately 50 feet, occurred <br />approximately 700 feet upstream of County Road 291. <br /> <br />The BFEs increased and decreased along the reach of Rifle Creek affected by the changes in the f10wpath <br />of Rifle Creek Splitflow. The BFEs increased along Rifle Creek from approximately 2,600 feet upstream <br />of Old Creek Meadows Bridge to approximately 3,470 feet downstream of County Road 291. The <br />maximum increase in BFE, 4.3 feet, occurred at the confluence of Rifle Creek and Rifle Creek Splitflow. <br />The BFEs decreased from approximately 3,470 feet downstream to approximately 1,350 feet downstream <br />of County Road 291. The maximum decrease in BFE, 0.5 foot, occurred approximately 2,000 feet <br />downstream of County Road 291. The SFHA width increased and decreased along Rifle Creek. The <br />maximum increase in SFHA width, approximately 200 feet, occurred approximately 400 feet upstream <br />of the confluence of Rifle Creek and Rifle Creek Splitflow. The maximum decrease in SFHA width, <br />approximately 150 feet, occurred approximately 1,900 feet downstream of County Road 291. The <br />flood way width does not change along Rifle Creek. <br /> <br />A separate LOMR was issued on the same date as this LOMR to describe the effects of this revision on <br />the City of Rifle. <br /> <br />The modifications are shown on the enclosed annotated copies of FIRM Panel 1352 B; FBFM Panel 1352; <br />Profile Panels 84P, 85P, and 104P; and the Floodway Data Table for Rifle Creek Splitflow and Rifle <br />Creek. This LOMR hereby revises these panels of the effective FIRM and FBFM and the Flood Profiles <br />and Floodway Data Table in the FIS report, all dated January 3, 1986. <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 />Rifle Creek Splitflow: <br />Just downstream of County Road 291 <br />Approximately 550 feet upstream of County Road 291 <br />Approximately 200 feet downstream of divergence from <br />Rifle Creek <br /> <br />5,461 <br />5,468 <br /> <br />5,457 <br />5,467 <br /> <br />5,475 <br /> <br />5,475 <br />
