2. Move Building The entire building could be moved to a new location outside the flood plain. Moving the building would be a relatively expensive operation. Probably the most negative effect of moving the building would be the loss of the relationship between the building and the stream. The proximity of the building to Sweetwater Creek is an important part of the camping experience offered by the resi~ dence hall in its present location. 3. Channelize Stream Lowering the channel bottom of Sweetwater Creek approximately 2 feet and slightly widening the channel would provide suf- ficient capacity to carry the entire 100 year flood runoff without encroachment into the area of the residence hall. Some type of levee arrangement would still be necessary upstream to capture the diffuse overland flow water which spread out some distance upstream from the camp area. Significant amounts of sediment would be developed in the stream during the channelization operation and would con- tinue for some time after the completion of construction until the stream has re-stabilized itself. 4. Levee A levee can be constructed upstream from the residence hall and continued a short distance downstream from the hall to direct flood flows around the residence hall. The levee construction would not affect the stream channel itself, would allow the building to remain in its present location and would be relatively inexpensive to construct. CONCLUSIONS AND RECOMMENDATIONS Based on a 100 year flood discharge of 2,700 cfs, the new residence hall would be surrounded by flood waters during the 100 year flood event, although the finished flood would be approximately 0.3 foot above the flood plain level. The velocity of flow in the overQank area around the residence hall would be approximately 4 feet per second. -6-
