The VSMP erosion and sediment control plan modification to allow interim measures (as final erosion control measures have yet to be installed), or to change the final design of sediment trapping measures, has been reviewed; This plan is incomplete and could not be approved. The computations provided for interim SB -4 must follow the state guidelines, which also applies to the release channel. (The plans refer to this as a basin, but there is no riser or pipe.) The added measures along Rt. 20 to accommodate the pond outfall and ditch, and culvert protections were not shown on the plans, and were not engineered. The phase lines drawn through SB -2 are unexplained, and do not appear workable. Furthermore, the contractor has stated the baffle is impossible to install in the rock bottom. The existing sediment trap removal next to northern property boundary was not included. The stockpiles and changes to SB -3 and the adjacent trap were not included. These areas appear to be drawn the same as on approved final plans. If the intent is to rebuild these facilities to meet original plans, please have this commence at once.
