One story of a five-story office building is being renovated for new office space. The site has a zero-lot-line and is completely paved with impervious material. The pre-development discharge rate of stormwater is 10,000 gallons. What maximum post-development discharge rate will qualify for Stormwater Management: Quantity Control?
A: 8,000 gallons
B: 10,000 gallons
C: 7,500 gallons
D: 9,000 gallons

参考答案: C

本题解释:
Notes:

This 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 that 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).
