The typical green wall has very little impact upon storm water runoff. This is because the system footprint is vertical and is quite small in terms of horizontal surface area. In addition, the building overhang often blocks rain.

If storm water management is a high priority, the rain should first be captured from the roof, stored in a cistern, then filtered and used to irrigate your LiveWall vertical garden.
