12:00 pm – 1:00pm
Please join the CWEA’s Stormwater Committee and Martin Covington with Carroll County, MD’s Stormwater Management Program, to learn about design modifications that scale standard small sand filters up to regional facility size. Standard details, design procedures, engineering criteria, inspection procedures and maintenance requirements will be presented with web addresses, current updates and improvements discussed.
Observations since 2008 have clearly indicated that streambank regeneration is occurring downstream of these regional sand filters. Efforts have been undertaken to develop a procedure to measure and quantify the water quality benefits associated with downstream regeneration. Along with physical results showing stabilization of banks and establishments of new floodplains, hydrologic modeling of two watersheds is presented confirming that forest condition hydrology has been re-established down to the first confluence. This presentation will review the current work to quantify these observed benefits, and provide methodology for calculating appropriate nutrient reductions.
1.0 Professional Development Hours (PDFs) will be offered for this webcast.
