: Approach to land development (or re-development) that works with nature to

manage storm water as close to its source as possible

LID(Low Impact Development)

• Importance of permeable layer

1. Set up an eco-friendly permeable layer in the Source

2. Permeable layer can catch TN, TP, SS which cause Eutrophication
