<br />. <br /> <br />. <br /> <br />Exhibit I - Scope of Services <br />Metropolitan Water Supply Investigation <br /> <br />November 17, 1993 <br />Page 21 <br /> <br />Methodology and Evaluation Techniques <br /> <br />Work under this task would include an initial expansive "brainstorming" phase followed <br />by a narrowing or "specifying" phase. During the brainstorming phase efforts would focus on <br />generating ideas, exploring general availability of data and models, and establishing working <br />relationships with T AC members other water provider participants, <br /> <br />During the specifying phase work would focus on refining and specifically defining <br />water supply opportunities to be investigated. Related data gaps and overall criteria for <br />evaluating the benefits and impacts of identified opportunities would also be identified. Key <br />interests would be surveyed regarding technical issues including modeling capabilities, data <br />availability, consistency of systems integration options with individual water supply planning <br />and other relevant information. The Project team also needs to be aware of institutional and <br />legal issues so that relevant technical problems can be addressed, but the Project must retain <br />creative flexibility in this area so as to avoid undue legal and political restraints. <br /> <br />The need to narrow and better define water supply opportunities is particularly <br />important. For example, the Barr Lake Plan is probably the least defined and, to date the least <br />studied of the Project's three initially identified water supply opportunities. An effort should <br />be made to eliminate those parts which do not appear viable and concentrate on those concepts <br />or scenarios that are the most attractive to the Barr Lake owners and municipal users, Because <br />of the Plan's number of suggested exchanges or mechanisms and various combinations thereof, <br />we suggest that an effort be made to identify and study in detail no more than three scenarios <br />specific to the Barr Lake Plan. <br /> <br />This task would also focus on how to best dovetail the overall MWSI Project process <br />with other ongoing water supply planning efforts in order to efficiently and comprehensively <br />explofe metro Denver area water supply planning options. <br /> <br />As the most promising water supply opportunities are more specifically defined it will <br />also be necessafY to identify associated technical, environmental and institutional issues that <br />will need to be addressed in the study process. As these issues emerge, evaluation criteria <br />should be defined to measure the comparative benefits and costs of various options. Evaluation <br />criteria could include factors such as impacts on irrigated agriculture, impacts on wetland, <br />impacts on water quality, the cost of facilities required and federal, state and local permitting <br />requirements. <br /> <br />Work under this task would be accomplished through a series of wOfk sessions with <br />T AC and with major interested parties including Denver W atef, Northern Colorado Watef <br />Conservancy District, Metro Denver Reclamation District, the Barr Lake Companies, and the <br />Arapahoe County and Douglas County water groups. <br /> <br />Linkages With Other Tasks <br /> <br />This task will more specifically define all other tasks in the Project and should precede <br />all other substantive investigations. <br /> <br />Likely Sources of Information To Be Used <br /> <br />A wide variety of input would be received from T AC members and other water interests, <br />OSE data related to surface water diversions, wells and groundwater use would also be initially <br />reviewed, <br />
