I'm working on a project being built in a designated industrial park area. The whole industrial development area had previously had a water retention pond created to service all future site development in the area. Can a new construction project utilize the existing water retention pond, which is located nearby but technically outside of the LEED project boundary, to comply with this credit? GI and LIDs are being used to capture some of rainwater for reuse on site but would also direct some on site rainfall toward this dedicated offsite pond nearby as it was designed.
The argument is why develop more land area on site to manage the water when an appropriate water management vessel was already created for the general development area already. Anyone have any experience with such a scenario?

This doesn't really meet the intent of GI, nor is it possible to discern without knowing more about how the basin operates...if this is a leftover basin from older developments it probably provide little more than rate control for higher volume, lower frequency storms, which is the exact opposite of what we are trying to achieve with this credit.
