Background as an Expert Witness <br />As an expert witness I have previously testified in Colorado water courts Water Divisions <br />1, 4 and 5 for issues related to the Golden (Division No. I Case 98CW448), Vail (Division No. 5 <br />Case OOCW259), Breckenridge (Division No. 5 Case OOCW281), Gunnison (Division No. 4 Case <br />No. 02CW38) and Steamboat Springs (Division No. 6 Case No. 03CW86) Water Parks. I also <br />gave testimony before the CWCB for issues related to the Pueblo and Gunnison Parks. In all <br />cases I have been qualified as an expert witness with regard to my experience as a Professional <br />Engineer, Whitewater /Boating Park Designer, and Expert Kayaker based on the qualifications <br />listed above. <br />Boating Park Design <br />Boating Park design begins with an information gathering phase. In this phase <br />information about the site and the people who will use it are gathered. Necessary site <br />information includes existing gradient, width and depth of the existing riverbed, historical <br />average and peak flows, and existing features in the region of interest. User information includes <br />type and ability levels of the different expected user groups. User groups can include freestyle <br />boaters, slalomists, recreational boaters, rafters and people in inflatables among others. Public <br />meetings are held in order to determine the design objectives of the community and the people <br />who will use the park. <br />The designer then uses this information to design the layout of a particular course and <br />tailor it for a particular community. The layout is typically a balance between the desires of the <br />many user groups, the constraints of the riverbed in which the park is created and the budgeting <br />constraints of the project. Parks with sufficient drop and flow allow for the most dynamic <br />features and are typically the venues that attract the most users and the most big events. <br />Once the layout of the course is established the design of the particular features are <br />tailored to the existing riverbed. In- stream modifications are difficult and require careful <br />planning. The structures placed in the stream must be stable yet create the desired feature <br />without decreasing the capacity of the existing streambed or hindering the stream's natural <br />sediment transport mechanisms. The structures are also designed to create a navigable stream at <br />water levels that vary from typical lows to extreme floods. Within this spectrum of potential <br />water levels the structure must not create a dangerous hydraulic feature. Additionally, flow <br />control needs to be established and maintained throughout the boating park in order to prevent <br />bank erosion or flow conditions that are hazardous to in- stream navigation. <br />-3- <br />
