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.

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 skimmer may need checking occasio

  In 2016, we published a brochure entitled “Let’s Look at Sediment”.  It is still a relevant informational document today.  Here is the link to the brochure and one of its many facts:   Let’s Look at Sediment   “Sediment degrades aquatic habitat and turbidity restricts light and aquatic plant growth. This disrupts the food chain and impairs fish and aquatic insect populations.”   Perry L Oakes, PE Program Coordinator AL Erosion and Sediment Control Program

  The 2018 version of the Alabama Handbook for Erosion Control, Sediment Control and Stormwater Management on Construction Sites and Urban Areas (a.k.a., The Blue Book ) will be up for revision in 2022. FYI – Plans are to make available the proposed major changes to the Blue Book on our new website for interested individuals to look at and review.  Constructive comments on any of the contents in the 2018 Blue Book and these proposed major revisions for the 2022 Blue Book should be provided in writing to the Alabama Soil and Water Conservation Committee at this address: Alabama Soil and Water Conservation Committee P.O. Box 304880 Montgomery, AL 36130-4800 Comments are welcome anytime, but to make sure your thoughts are considered for the 2022 Blue Book, please get them in by December 31, 2021. So, this is your opportunity to make sure Alabama’s Blue Book continues to be the most technically sound E&SC Handbook of any state. Also, go to either the Google Play Store or
