A 5 story office building is being constructed on the site of an old warehouse. The site has a zero-lot-line and is completely paved with non-porous pavement. The pre-development discharge volume of stormwater is 10,000 gallons. What post-development discharge volume would qualify for Sustainable Sites Credit, Stormwater Design-Quantity Control?
A: 8,000 gallons, or less
B: 10,000 gallons, or less
C: 5,000 gallons, or less
D: 7,500 gallons, or less

参考答案: D

本题解释:
Notes:
The site has an imperviousness greater than 50% because it is completely paved, so
Option 2 must be met for the requirements. A stormwater management plan must have a
25% decrease in volume. The pre-development discharge rate is 10,000 gallons, so the
post-development discharge rate must be 7,500 gallons or less (25% less than 10,000
gallons).
