They expressed concern that it will direct run off towards replicated wetland. Mr. Kirby explained that he is not concerned about that because the area is flat. The commission expressed concern over the change in the sediment basin. They requested more details from the engineer regarding why and how the design changed. The commission asked why the engineering drawings still stated that they were 60% complete. Mr. Kirby said that it is the practice of the engineering company to not stamp or mark the drawings complete until the Conservation Commission approves the plans. He added that any changes in the plan would have to go to the Commission for approval. The commission requested clarification regarding the use of live stakes. Mr. Kirby clarified that they will just be using oak stakes and they will remove live stakes from the plan. The commission asked about the piezometer readings. Mr. Kirby explained that they are not too low considering we are in a drought; they are within the range of hydric soils. He added that a watering O and M plan for the plants has been added. The commission requested that they submit a list of invasive species that they will be removing. The commission suggested the MIPAG list.
