Hello all,

Our project is intending to use a LEED boundary that is only a portion of a larger site. The larger site is a National Cemetery and the LEED boundary includes only the areas that are immediately servicing the buildings on site. As part of meeting credits SSc6.1 and 6.2 (stormwater) we are designing a wet retention pond outside the LEED project boundary that will capture the runoff for the LEED project boundary land as well as a majority of the larger site.

The larger site's irrigation system will be drawn from this wet pond, and is intended to supply the irrigation needs for the larger site, which then includes the land within the LEED boundary. Only in times of drought would the irrigation be supplied by a potable source, but based on our calculations we should easily reduce the need for potable water for irrigation by 50%.

Since this wet pond is collecting the stormwater from the LEED site and the larger site, and supplying the irrigation for both the LEED site and larger site, can this constructed retention pond water be considered "captured on-site rainwater"?

Any advice would be most appreciated, thank you.
