Identify Areas and Causes of Stream Instability <br /> <br />Total estimated professional fees and expenses associated with Tasks Al through A3 are <br />approximately $26,000. One progress meeting with the project stakeholders will be conducted <br />under this Stream Instability task item to present the findings of the stream instability analysis and <br />demonstrate developed GIS instability mapping for comments and recommendations. <br /> <br />Task A.l. - Define Stream Instability <br /> <br />This task basically is defining a useable policy and guidelines for identification and management <br />of stream instability. We believe the CSU team can help us efficiently locate definitions of instability <br />used in other places throughout the world. We see this task as pulling together definitions and <br />management tools established elsewhere and customizing them specifically to the Roaring <br />Fork Valley. Defining instability will be more than describing vertical and lateral changes in the <br />channel; we will incorporate input from the wetlands and fisheries experts in defining impacts of <br />channel instability. Our work will be to produce a methodology and criteria for examining channel <br />instability that can be adopted regionally by regulators and land planners. <br /> <br />Work product under this task will be a section of the final report useable in land planning criteria. <br /> <br />Task A.2. - Identify Unstable Areas <br /> <br />This task will be a major portion of our work and comprise approximately one-fourth of the total <br />budget. Development of base mapping and information gathering will be conducted under this <br />task. Information will be pulled together into a useable format in GIS to identify unstable areas. <br /> <br />The importance of this project is to manage the river on a comprehensive and regional basis rather <br />than by individual segments and jurisdictional boundaries. This task can be completed as defined <br />in the Scope for the Roaring Fork River beginning with the reach from Difficult Campground above <br />Aspen downstream to the confluence with the Colorado River. Major tributaries (Castle Creek, <br />Maroon Creek, Woody Creek, Crystal River and Cattle Creek) will be include in the mapping for <br />one to two miles above the confluence with the Roaring Fork River. The Fryingpan River will also <br />be included for 13 miles above the confluence to the Ruedi Reservoir dam. <br /> <br />We will meet with all municipalities (Glenwood Springs, Carbondale, Basalt, Snowmass Village and <br />Aspen) and counties (Garfield, Eagle and Pitkin) to gather existing GIS information, mapping, aerial <br />photographs, land use information and boundaries. Base mapping will come from USGS <br />(Glenwood Springs, Cattle Creek, Carbondale, Leon, Toner Reservoir, Red Creek, Basalt, Woody <br />Creek, Ruedi Reservoir, Highland Peak and Aspen quadrangles only) and other available mapping. <br />We plan to use best available mapping (Le., 2-foot contour floodplain mapping) where available, <br />and tie into USGS mapping where no better information exists. Mapping will likely extend one mile <br /> <br />K:\Proposa1\02830-98\O 15\Scope.doc <br /> <br />Page I <br /> <br />July 14, 1998 <br />Offices WorldWide <br />
