<br />• post-development with an end-of-pipe SWM pond (green) discharge reaches the same peak flow as pre-development conditions but produces more runoff. The checkered yellow space between the blue and green lines shows the difference between the runoff volumes - this area is where LID can be used to reduce runoff by storing and infiltrating rainfall.
