Question 98: A LEED AP is making calculations to confirm that the project is eligible to pursue the Path 3: Zero-Lot-Line Projects Only—85th Percentile part of the SS credit Rainwater Management. If the total square feet of the whole lot of the building is 10,000 square feet, at a minimum, how much should the total square feet of the building be to be eligible for this path?

15,000 square feet (Correct answer)
30,000 square feet
10,000 square feet
20,000 square feet

Correct answer: 15,000 square feet

Explanation: Path 3 of the Rainwater Management credit is only for zero-lot-line projects in urban areas with a minimum density of a 1.5 floor-to-area ratio. (Zero-lot-line projects are types of projects in which the buildings are built on the entire lot.) For this question, since the project should have a minimum density of a 1.5 floor-to-area ratio, the total square feet of the building should be 15,000 square feet at a minimum. 1.5 FAR = 15,000 square feet / 10,000 square feet
