With LID, not all solutions are created equal. There is a hierarchy in the regulations for what is the preferred technology. So it’s not so much is it approved or not approved… there are certain preferred technologies that must be considered first, and if that doesn’t work, you consider the next option in preference. This is a huge difference in conventional stormwater regulations, which says technologies must be approved by state of local jurisdictions – and then everything is on a level playing field.
