What is the purpose of the initial land disturbance phase in a phased stormwater management plan?

The initial land disturbance phase in a phased stormwater management plan is primarily focused on managing sediment and runoff risks that arise when land is cleared or excavated for construction. This phase is crucial because it sets the stage for how effectively stormwater will be managed throughout the construction process.

During this phase, various Best Management Practices (BMPs) are established to prevent soil erosion and control sediment discharge into nearby waterways. These practices might include installation of silt fences, sediment traps, or other erosion control measures that aim to keep sediment on-site and mitigate the potential impact of runoff on the surrounding environment.

By prioritizing these controls early on, the project can minimize environmental degradation, comply with regulatory requirements, and promote sustainable construction practices. Thus, the initial land disturbance phase plays a critical role in ensuring that subsequent construction activities do not lead to significant sediment and runoff problems.
