An apartment complex is being built in a suburban area on a Greenfield site. The site has
an existing imperviousness of 25%. The pre-development discharge volume of
stormwater is 8,000 gallons. What can the maximum post-development discharge volume
be to qualify for Sustainable Sites Credit, Stormwater Design-Quantity Control?
A: 10,000 gallons
B: 4,000 gallons
C: 6,000 gallons
D: 2,000 gallons
E: 8,000 gallons

参考答案: E

本题解释:
Notes:
Note that the question specifically asks for the maximum post-development discharge
volume.
The Greenfield site has an existing imperviousness that is less than or equal to 50%. The
post-development peak discharge rate and the quantity must not exceed the
pre-development peak discharge rate and quantity to meet the requirements of
Sustainable Sites Credit, Stormwater Design-Quantity Control, Option 1. The question
gave a pre-development discharge rate of 8,000 gallons. The post-development
discharge rate would have to be the same or less than this pre-development discharge
rate.
Another option, not discussed in this question, is to implement a stormwater management
plan that protects receiving stream channels from excessive erosion by implementing a
stream channel protection strategy and quantity control strategies.
