Question
One of the requirements for the Sustainable Sites Credit. Rainwater Management is that projects must
A. maximize open space within the LEED project Boundary
B. calculate the total rainwater runoff for 75th percentile rainfall events
C. use Green Infrastructure and Low Impact Development techniques within the LEED project boundary
D. use a combination of both structural and non-structural measures to manage a 90th percentile rainfall event
Answer
C. use Green Infrastructure and Low Impact Development techniques within the LEED project boundary
Explanation
One of the requirements for the Sustainable Sites Credit: Rainwater Management is that projects must use Green Infrastructure (GI) and Low Impact Development (LID) techniques within the LEED project boundary.
GI and LID are design approaches that mimic natural hydrologic processes to manage stormwater runoff at its source. GI and LID techniques include strategies such as rain gardens, bioswales, permeable pavements, green roofs, rain barrels, cisterns, and vegetated buffers.
The other options are not requirements for the Sustainable Sites Credit: Rainwater Management. Maximizing open space within the LEED project boundary is a requirement for the Sustainable Sites Credit: Open Space.
Calculating the total rainwater runoff for 75th percentile rainfall events is a requirement for the Sustainable Sites Credit: Site Assessment. Using a combination of both structural and non-structural measures to manage a 90th percentile rainfall event is an option for meeting Option 1 of the Sustainable Sites Credit: Rainwater Management.
For the Sustainable Sites Credit related to Rainwater Management, LEED projects must utilize Green Infrastructure (GI) and Low Impact Development (LID) techniques. This approach focuses on managing rainwater at its source, minimizing runoff, and improving water quality. Techniques include the use of permeable surfaces, green roofs, rain gardens, and bioswales. These methods help mimic natural hydrology by capturing and treating stormwater on-site, reducing the burden on municipal stormwater systems, and promoting groundwater recharge. This strategy not only supports sustainable water management but also enhances the ecological and aesthetic value of the project site.
