We are working on a Core & Shell project on Cayman Islands and would like to pursue SS Credit 6.1 & 6.2. The project is on a previously developed site.There are deep wells existing on the property where currently all the rainwater is captured and therefore there is no runoff from the site at all. These wells will be retained in the project and used for the same purpose thus resulting in zero site runoff. How do we go about documenting this credit since both pre development & post development site runoff are zero.

You have on-site runoff or the wells would not capture rainwater. Therefore the calculation is in the pre-development vs post-development scenario. If the amount of building is increased it will add to the hardscape on the site. So you will need to demonstrate that those same wells can capture the additional run-off from roofs, sidewalks, roadways, etc.

Thank you Michele. We plan to add more underground wells on the site to accomodate all the excess runoff.I hope that we can achieve this credit.
