As part of this task, we will <br />develop a stream stabilization brochure for use by landowners and other non-technical river users <br />to educate them on channel stability, causes of instability and potential solutions. Technical <br />information on stream stabilization will be detailed in the comprehensive project report. <br /> <br />B. Examine Other River Issues <br /> <br />Total estimated fees associated with Tasks B.1 through B.6 are approximately $22,000. One major <br />progress meeting and one major public workshop will be conducted under this Other River Issues <br />task item to present the findings of the analyses and to focus on the final work product. <br /> <br />Task B.1. - Identify Areas of High Flood Hazard <br /> <br />This task basically pulls together all the available floodplain information into the GIS for use with <br />the analysis. We look forward to working with the CWCB to obtain all available floodplain <br />mapping. As we showed in the interview, mapped floodplain delineations (floodway and 100-year <br />floodplains) will be overlaid at exact scale with the USGS mapping and aerial photography to <br />clearly show the present relationship of river and regulated floodplain. In most cases, as we <br />understand, the floodplains are not in digital format and will need to be carefully digitized into the <br />GIS. In areas where the mapping is in CAD such as Eagle County, this information can readily be <br />brought into the GIS. <br /> <br />No new HEC-2/HEC-RAS modeling will be completed under this task. <br /> <br />Task B.2. - Identify Habitat and Recreation Concerns <br /> <br />This task identifies a cursory economic assessment of the habitat and recreational value of the river. <br />Information from the Chamber of Commerce and sales tax revenue will be used in the evaluation. <br />We will identify on the GIS areas of public access on the river. We will also gather information on <br />rafting and kayak excursions, guided fishing tours and other commercial ventures utilizing the river <br />corridor. In addition, we will gather existing information on habitat value. This information will <br />be used to assess impacts of instability on habitat and recreation. For example, unstable reaches <br />may result in only fast moving water and a loss of trout habitat. The Division of Wildlife has much <br />information on fish counts and changes in the fish population over time (i.e., a shift in population <br />from rainbow trout to white fish) which can be used in this study. This task will primarily be <br />completed in-office utilizing existing studies and telephone interviews. <br /> <br />A workshop will be conducted as part of this task to involve active users of the river in this <br />comprehensive project. The workshop will be conducted in the Roaring Fork Valley, likely in <br />Basalt, to identify the issues, educate the public on the goals of this project and focus on needed <br />solutions. BRW will prepare flyer information and a newspaper article to notify the public of the <br />workshop, but local participation by other stakeholders will be necessary to get the information out. <br /> <br />K:\Proposal\02830-98\O 15\Scope.doc <br /> <br />Page 3 <br /> <br />July 14, 1998 <br />Offices Worldwide <br />
