A project site is 75% impervious. The project team wants to improve the stormwater
performance from the pre-development runoff rate. What must occur with the stormwater
to achieve a LEED credit?
A: Post-development quantity must be 50% less than the pre-development quantity only
B: A stormwater management plan must be implemented that results in a 25% decrease in runoff from 2-year24-hour design storm
C: Implement best management practices for 80% of the post-development rate and quantity
D: Post-devel

参考答案: B

本题解释:
Notes:
There are two compliance paths for Stormwater Quantity Control:
Case 1. Existing Imperviousness 50% or Less and
Case 2. Site with Existing Imperviousness Greater than 50%.
The question stated the site was 75% impervious: thus, Case 2 requirements must be met.
For Case 2 a stormwater management plan must be implemented that results in a 25% decrease
in the volume of stormwater runoff from the 2-year 24-hour design storm.
For Case 1 the pre and post rate/quantity must be equal.
