  This type of Inlet Protection should not be used. Inlet protection devices are to be structurally sound to withstand sediment and hydrostatic loads without failure due to buckling, fabric sagging, or undermining.  Whether man-made or manufactured, the device should pond water to the designed depth to allow the heavier soil particles to settle without going into the storm sewer.   Perry L Oakes, PE Program Coordinator AL Erosion and Sediment Control Program

Erosion and Sediment Control Tip #76

  New seeds covered with erosion control blanket will germinate and penetrate the blanket.  When a blanket is placed on existing vegetation, the result is “tenting”.  So, when using erosion control blanket, have a clean newly seeded surface with the blanket secured to the soil surface.   Perry L Oakes, PE Program Coordinator AL Erosion and Sediment Control Program
