<br />HMG_TO08-A13_Long 9 <br />project to establish a distinct recognizable identity. The scale <br />of the project may potentially warrant multiple <br />complementary aesthetic treatments rather than just one <br />uniform theme dependent upon further review. <br />d. Prepare comparative cost estimates for each alternative. <br />e. Prepare hydraulic structures aesthetics design drawings. <br />i. At a minimum, prepare drawings for one (1) control structure <br />and one (1) aqueduct. <br />ii. Coordinate with design team members on technical aspects <br />of the hydraulic structures designs. <br />iii. Prepare conceptual plan, elevation, and section drawings that <br />illustrate different hydraulic structures types using the <br />selected preferred alternative theme(s). <br />f. Prepare prototypical hydraulic structures aesthetics design models. <br />Prepare conceptual 3D computer models using the Sketchup Program <br />that illustrate prototypical conditions and select design details utilizing <br />the selected preferred alternative theme(s). <br />g. Develop one (1) photo-realistic 3D visualization graphic illustrating the <br />incorporation of the preferred alternative design at a specific project <br />location. <br />h. Prepare a Hydraulic Structures Aesthetics Technical Memorandum to <br />serve as a guide for final design and as a record of the process by <br />which aesthetic design decisions were made. Include an executive <br />summary, narrative, design guidelines, meeting records, and a <br />summary record of decisions matrix. <br />i. The narrative should summarize the basis for the selected <br />preferred alternative theme(s) and intended application <br />including but not limited to: project background, site and <br />community context, associated studies, alternative themes <br />considered, bridge types, retaining wall types, and other <br />design features. <br />ii. Prepare hydraulic structures aesthetics design guidelines. <br />Refine and format the graphic illustrations of the prototypical <br />and bridge-specific studies prepared in task above that will <br />serve as guidelines for the final design phase of each <br />hydraulic structures. <br />iii. Summary Record of Decisions Matrix. In simple matrix table <br />format, list the selected hydraulic structures aesthetic options <br />as a quick summary reference. <br />X. BASELINE STREAM BANK EROSION EVALUATION <br />1. Purpose: To establish baseline data with historical references of stream bank <br />erosion and channel planform changes along the Red River and associated <br />tributaries in the Fargo, ND and Moorhead, MN region using GIS aerial imagery <br />and analysis. <br />2. Background: The Project is being designed and constructed to reduce the <br />impacts of Red River flooding in the Fargo/Moorhead area. River systems in DRAFT
