A project for an office renovation includes site improvements to an existing concrete parking lot of average slope. A civil engineer has determined that the pre-development existing imperviousness of the site is 25%. The project team would like to qualify for Stormwater Management-Quantity Control. How can stormwater runoff be managed to qualify for this option?
A: Filter and treat water on site
B: Implement a management plan that reduces water runoff by 25%
C: Ensure that post-development peak discharge is less than or equal to pre-development peak discharge
D: Reuse stormwater volume generated for non-potable uses, such as for landscape irrigation or custodial uses
E: Implement a stream channel protection strategy with quantity control

参考答案: C

本题解释:
See Sustainable Sites Credit, Site Selection, Stormwater Design-Quantity Control, Requirements

A building that prior to development has less than or equal to 50% imperviousness needs to implement a stormwater management plan with a post-development discharge equal or less than the pre-developed 1.5-year/24-hour rate and quantity discharge.
