In the previous exercise an “as-is” model was developed to estimate predevelopment runoff from the site. A detention pond was then sized to reduce the new or post-development (“to-be”) peak runoff to the estimated predevelopment value for the 10y design storm. In this exercise, we complete the dual drainage design with a 100y design storm.
