If I understand correclty, we can use the table in the reference guide with several BMPs to determine the removal efficiency.

Hi! Where can we find accepted values for tss removal efficiency of a meadow or other tipes of vegetation?

We have site that is located about 600m from the sea, hence the stormwater will be discharged to the sea instead going to municipal infrastructure.

I work on the project where it is impossible to design non-structural measures because soil can´t infiltrate almost any water.

hi there, here's what will probably be an easy question for you but is stumping me, as this is my first time documenting this credit.

The civil engineer on our project made the following comment : "Item 6.2, quality control: all exfiltration trenches accepting rainwater discharge are "dry" and that is considered as pretreatment

I'm working on a major remodel project next to the ocean.

If we are increasing the total impervious area on the site, but treating the stormwater to reduce the TSS, do we still meet the intent of the credit?

use of lead metal downspouts in stormwater systems does LEED NC v2009 (v3) prohibit the use of lead based metals?

Hello, I would like to get confirmation on whether the following approach of demonstrating compliance with LEED requirements could be accepted or not.
