Long Leaf Mall Bioretention Makes the Grade with NCSU
This new bioretention device will now filter runoff from the parking lot to prevent pollutants from entering local watersheds. Many thanks to the successful partnership with NCSU and our own Dragonfly Pond Works contracting team!

Bioretention Soil Media-CH etouches
bioretention soil mixes 2 to 4 percent passing the 200 sieve ideal. Fines should not be above 5 percent for a proper functioning specification. Sandy bioretention soil mixes should provide excellent water quality performance. Design with caution for systems with under-drains in P and N sensitive basins.
Bioretention Filter Media Benedict Industries
bio-retention filter media Benedict's 'all-in-one' bio-retention profile complies with the Adoption Guidelines for Stormwater Bio-filtration Systems (CRC WSC 2015). The profile comprises three individually manufactured layers with the necessary characteristics to enhance hydraulic conductivity and ensure optimal bridging.

3.8 Bioretention/Biofiltration Soil Media and Drainage
Bioretention Soil Media (BSM) is a formulated soil mixture that filters pollutants from stormwater, retains moisture, and supports healthy vegetation. It is used in LID BMPs including Bioretention, Biofiltration with Partial Infiltration, and Biofiltration with No Infiltration. BSM consists of 60-80% sand, up to 20% topsoil, and 20% of an
CHAPTER 9. 1 Bioretention Systems njstormwater.org
Bioretention Systems . Definition . Filter fabric should not be placed at the bottom of the soil planting bed in a bioretention The sand layer serves as a transition between the planting soil bed and the gravel layer and underdrain pipes. It must have a minimum thickness of 6 inches and consist of clean medium aggregate concrete sand

Filtering Practices BMP Inspection checklist
Filter Media Annually Stormwater does not percolate uniformly through the planter. If water remains 36-48 hours after storm, sources of possible clog-ging shall be identified and corrected. Filter media may need to be raked, excavated and cleaned, or gravel/soil shall be replaced to correct the problem. Holes that are not consistent with
Fly-Ash-Amended Sand as Filter Media in Bioretention Cells
Based on this relatively limited data set, these fly-ash amended bioretention cells performed 49% better than those with a sand-only filter media layer currently reported in the literature.
Performance Enhancing Devices for Stormwater BMPs
This project identified a variety of PEDs that can be incorporated into bioretention, sand filters, and other stormwater BMPs to increase nitrogen and phosphorus removal. Common PEDs include adding media amendments, incorporating an internal water storage zone in the underdrain system, and maximizing plant uptake.

Washington State Department of Ecology Silva Cell Functionally Equivalent to a Bioretention Facility. The benefit of using the bioretention element instead of the sand filter element is that both flow control and treatment performance can be evaluated. Silva Cells provide treatment by filtering stormwater runoff through a soil media that
