Engineered soil for controlled infiltration in basin?
Engineered soil for controlled infiltration in basin?
(OP)
I have a project in an area underlain by limestone. I want to control infiltration rates within my basins and other BMPs, but not seal them. Can anyone point me to a resource which will help me design a layer of soil to line the basins that will control infiltration?
Are there any controlled-rate geotextiles? The lowest flow rate I could find is 5gpm for the fabrics.

In other words, instead of trying to line the entire bottom with an engineered soil designed to slow-the-flow (and may or may not perform as intended), seal the bottom except for one or more "window(s)" where water percolates into the native material (for which performance can be measured during the design phase).

Conducted percolation tests on the soils and rates were in the 2 to 3 miutes per inch range.The soils are sandy,gravel mix. Local health department will not allow a system to be placed in the these soils. I am looking for a procedure to remediate the soils to slow the percolation rate.
