Erosion and Sediment Control Tip #32


 

There are many Sediment Control Practices that require the captured sediment to be removed and properly disposed of when ½ of the sediment storage volume has been reached.  First, if you are having to deal with sediment removal on your construction site, you should look upslope and fix the erosion control methods and practices.  However, if you must remove sediment, do so without destroying the sediment control practice. Where is the location for placement of the sediment and how should it be “properly” disposed of?  Most likely the sediment will be saturated.  This requires the material to dry out somewhat before it can be stabilized.  Locate a good area on the jobsite.  Preferably a site with good vegetation downslope and not near a receiving stream.  If there is no vegetation that could serve as a grass filter, then you’ll probably need to install a silt fence to control the runoff. Stack the removed sediment as much as it will stack and let it drain. As soon as it is drained to allow spreading, blend the material into the landscape and vegetate it with permanent vegetation by incorporating the required lime and fertilizer, and spreading the seed and mulch (See the Permanent Seeding practice in Alabama’s Blue Book).

Today’s Erosion and Sediment Control Tip: #16

  Today’s Erosion and Sediment Control Tip Sediment Basins require a device to dewater from the surface of the basin to remove the cleanest (less turbid) water.  This is often accomplished with a skimming device that is designed to remove the stored construction runoff over a period of 2 to 5 days.  It is important that the skimmer be installed and maintained properly. Skimmers must have a flexible connection to the rigid pipe or riser system that goes through the dam.  It should easily operate at all design elevations.  When placed on a principal spillway riser, the pipe from the skimmer to the flexible connection should be about 1.5 x the height of the riser structure. The flexible pipe outlet at the rigid pipe or riser system through the dam should be at the standing pool elevation to ensure the skimmer does not function below the required elevation. A rock pad should be constructed for the skimming device to rest on when discharge is complete.  The skim...

  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

Erosion and Sediment Control Tip #71

  Instead of raised islands in a parking lot, why not use a depressed island (Bioretention Swale or Bioswale).  This allows for some stormwater runoff to infiltrate the soil, decreases the peak runoff, decreases the volume of runoff, and allows for smaller stormwater pipes.  Makes sense to me.   Remember: The Early Bird rates for Clear Water Alabama 2024 end August 15, 2024.   Perry L Oakes, PE Program Coordinator AL Erosion and Sediment Control Program
