Notes:

Note that the question specifically asks for the maximum post-development discharge volume.

The site has an existing imperviousness that is less than or equal to 50%. Because of this, 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.
