Stormwater Protection

Regarding Stormwater Design - Quantity Control, it looks like we should be able to make a case for utilizing a detention pond located outside of the LEED boundary that serves many of the sites on the campus. But since this detention pond serves a much larger area than our current project alone, would LEED make us prove the detention pond can meet this requirement for the entire area served to earn the point? Has anyone ran into a similar scenario? Thanks!

Hi Erin,

I found the following ruling on this credit:

"Projects with stormwater control measures outside the LEED project boundary may be accepted if the measures appropriately take into account neighboring facilities by demonstrating that the existing stormwater management systems that serve the LEED project boundary meet the LEED requirements for all areas within the site serviced by those systems."

The second ruling on this page from USGBC explains this in more detail.

So, I believe you would need to prove that you would need to prove that the detention area will meet the LEED requirements for the entire campus, including your building. This means that all properties using the treatment train would need to be able to be treated at the same time.

I hope this helps!
