LEED Green Associate (LEED GA) — Question 96

In a large site that has a short, intense rainy season and a long, dry season, what component of a collected rainwater irrigation system is most likely to make it cost prohibitive over a conventional system?

Answer options

• A. Irrigation piping systems
• B. Irrigation control systems
• C. Rainwater storage cisterns
• D. Landscaping plant selection

Correct answer: C

Explanation

The correct answer is C, as rainwater storage cisterns require significant investment for construction and maintenance, especially in environments with limited rainfall. While irrigation piping and control systems can also incur costs, they typically do not reach the same levels of expense as the storage solutions needed to effectively manage and utilize collected rainwater.
