→Geotextiles/filter fabric
*In Finland the use of a choker course has been advocated for in place of filter fabric as replacing a clogged fabric layer would disturb established [[planting]]<ref>Tahvonen, O. 2018. Adapting Bioretention Construction Details to Local Practices in Finland. Sustainability 10(276). doi: doi:10.3390/su10020276.</ref>.

*However, a recently revised document in Oklahoma suggests that geotextiles have a place in the base of the reservoir, but a choker course is best employed between layers inside the practice<ref>McLemore, A.J., J.R. Vogel, and S. Taghvaeian. 2017. “Bioretention Cell Design Guidance for Oklahoma.” http://pods.dasnr.okstate.edu/docushare/dsweb/Get/Document-10743/BAE-1536web.pdf.</ref>

*Filter fabric certainly has application in supporting backfield of native soils over [[infiltration trenches|infiltration]] and [[exfiltration trenches]] which comprise crates or [[clear stone]]<ref>Stormwater Management for Smart Growth, Allen P.
