Erosion and Sediment Control Tip #78

  This picture clearly shows the difference between adequate mulch (left) and too little mulch (right).  Adequate mulch when used alone for soil protection should have 100% ground cover. Inadequate mulch cover results in splash erosion which often initiates the erosion process.   Perry L Oakes, PE Program Coordinator AL Erosion and Sediment Control Program

  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

Erosion and Sediment Control Tip #75

  If you “do it right the first time”, you shouldn’t have to repair a site.  Here is one example from the 2010 Clear Water Alabama event where the project is now over 14 years old.  Riprap outlet protection was installed at the pipe outlet to dissipate the energy of the flowing water.  The eroded channel was shaped to design dimensions, covered in TRM, infilled with topsoil, and sodded.  Other than a little vegetation management needed at the riprap outlet, the site is still pristine.     Perry L Oakes, PE Program Coordinator AL Erosion and Sediment Control Program

  Project Sites need proper planning for Construction Sequencing, Erosion and Sediment Control, and Stormwater Management.  I kind of wonder about the planning on this site?   Perry L Oakes, PE Program Coordinator AL Erosion and Sediment Control Program

  We all enjoy a trip to the beach.  Please stay on the designated pathways and Dune Walkovers.  Newly planted Dune Vegetation can be easily destroyed by foot traffic.    __________________________________________________________________________ Clear Water Alabama 2024 is only about 4 weeks away!!  Registration ends September 20 th !!

  Could someone please explain to me why landscaping is usually the “LAST” item to be complete on a construction job? Exposed soil should be stabilized at EVERY opportunity during a construction project.     ONLY 9 DAYS LEFT FOR EARLY BIRD REGISTRATION FOR CLEAR WATER ALABAMA!!   Perry L Oakes, PE Program Coordinator AL Erosion and Sediment Control Program
