Dear All,
Regarding NC-v4 SSc2: Site development - protect or restore habitat, vegetated roof may be counted if roof vegetation meet the credit requirements. However we need to clarify if soils used on vegetated roofs should meet the credit requirements once the soils used on greenroofs is typically specific for structural reasons.
Can we use any kind of soils on greenroofs?
Thanks in advance,

Hi Pedro,
This is a great question. As you said, the reference guide only says that the density of the project and the roof vegetation must meet the credit requirements for the roof to be counted towards the total restored area. In the Soil Restoration section, it also says that you must restore soil characteristics "necessary to support the selected native vegetation types." Further guidelines are in the table on that page.
Have you already determined that the soil you need for structural purposes will not meet the criteria of this credit? If you're vegetation is native and complies with the credit, I bet the necessary soil to support this vegetation complies too!
