What is the minimum flood pool volume required per acre of drained area?

1. 1,200 cubic feet

2. 1,800 cubic feet

3. 2,400 cubic feet

4. 3,000 cubic feet

The correct answer is: 1,800 cubic feet

The minimum flood pool volume required per acre of drained area in North Carolina is 1,800 cubic feet. This figure is established by the state’s guidelines for stormwater management, specifically designed to ensure that sufficient storage is available to accommodate runoff from rainfall events. This regulation helps to mitigate flooding and protects water quality by allowing for the detention of stormwater, which can then be gradually released or infiltrated to reduce the peak flow during heavy rains. This volume is essential in managing the impact of development on local hydrology; by maintaining this standard, builders and developers can help control the effects of increased impermeable surfaces, which often lead to greater runoff and associated environmental issues. Understanding these requirements is crucial for licensed contractors and builders to ensure compliance and promote sustainable construction practices.
