Which document is essential for the local approval process in stormwater management?

In stormwater management, both the Stormwater Management plan and the Erosion and Sediment Control plan are crucial for the local approval process. Each of these plans serves an essential function in managing the impacts of stormwater runoff and preventing erosion, which can lead to sedimentation in water bodies.

The Stormwater Management plan outlines strategies and practices to control and manage stormwater runoff in a way that minimizes pollution and flooding. It typically includes design standards for systems that manage the quantity and quality of stormwater.

The Erosion and Sediment Control plan focuses specifically on preventing soil erosion and managing sediment during construction activities. This plan outlines measures that will be implemented to control soil disturbance and ensure that sediments do not leave the construction site, thereby protecting nearby water bodies and maintaining water quality.

Having both plans submitted and approved is essential to demonstrate compliance with local regulations and standards, ensuring that the construction project addresses both immediate sediment control and long-term stormwater management. Together, these documents provide a comprehensive approach to environmental protection during and after construction activities, making them indispensable for the local approval process.
