Hello, in my project there will be no irrigation at all because of the adapted plants plant in all the green roofs. How do we demonstrate the achievement of the credit? Which documents must we submit for the compliance?
Thanks

We submitted a statement from the landscape designer along with pictures of the temporal irrigation (small trucks with water tanks) during the plant establishment. That was sufficient for the reviewers.

We are planning our landscaping with native/adapted plants and we are not going to install permanent irrigation. During dry times of the summer, we may want to handwater plants using small trucks with water tanks to keep the landscaping from going brown. Is this acceptable if we want to achieve all 4 points on this credit?

No potable water use or no (long term) irrigation for a possible 4 points still require you to show the planting layout/pallete that proves you are taking advantage of native/drought tolerant plants, and are actually doing a real landscaping less the water. If you are manually watering the plants (actually planted in the soil), I guess you need to provide a schedule (name of person and his schedule). Seriously, achieving the 4 points should reflect the sustainability of the design level you are trying to achieve.
