What is the minimum number of phases required for sites greater than or equal to 10 acres?

For sites greater than or equal to 10 acres, the minimum number of phases required is three. This minimum requirement is often established in erosion and sediment control regulations to ensure effective management throughout the construction process.

Dividing such large sites into multiple phases allows for a more manageable approach to erosion control practices. Each phase can be designed and implemented with specific best management practices (BMPs) that correspond to the development activities occurring at that time. This helps to reduce the volume of sediment entering nearby water bodies and allows for better monitoring and maintenance of erosion control methods.

Furthermore, having a three-phase project aligns with environmental management goals, ensuring that there are systematic evaluations of conditions and practices as the project progresses. This phased approach also facilitates compliance with regulatory requirements, making it easier to adjust erosion control strategies as needed during construction.
