LD25 & Establishment Chute

Posted on September 1, 2010

Ashley provided background information and a brief discussion of the features in the study reach (RM 250.0-238.0). Representatives from environmental agencies, industry, and the Corps were present.

She explained the criteria she used to evaluate the alternatives and why she recommended Alternative 12. Then she asked for other alternative ideas, and it was suggested to adjust the Left Descending Bank (LDB) of the island at RM 244.5-243.8. So Ashley said she would test the alternative and let the group know the results.

Following, the group gathered around the model and observed Alternative 12 in the model.Some questions were raised about the bank line near the Batchtown Complex.Ashley told them she had recommended revetting some of the bank line near the scour at RM 243.6 LDB.Brian Markert and Ron Dieckmann also noted the recent water control structure, low berm, and revetment constructed on Batchtown's LDB. The project manager, June Jeffries, mentioned that the earliest the model study results could be built would be FY 12 or 13.

After the open discussion, Ashley confirmed with the group that Alternative 12 was the best alternative. She then told the group that she would run Alternative 19 (adjust the bank of island at RM 244.5-243.8L) and inform the group of the results. Everybody thought that was a good plan of action.
