What must be included in a phased stormwater management plan for sites with between 5 and 10 acres?

In a phased stormwater management plan for sites with between 5 and 10 acres, it is essential to incorporate at least two separate phases, with one of those phases directly addressing the initial land disturbance. This requirement ensures that the potential impacts of sediment and runoff are managed effectively from the very beginning of construction activities.

By including the initial land disturbance in the plan, it allows for the implementation of sediment and erosion control measures right at the onset, thus minimizing the risk of environmental degradation caused by stormwater runoff. The regulation typically emphasizes the need for a phased approach in managing stormwater because it allows for continuous evaluation and adjustment of best management practices throughout the project, thereby increasing the effectiveness of the stormwater management strategy over time.

This requirement fosters both compliance with environmental regulations and promotes sustainable construction practices, ultimately leading to better protection of water quality in nearby streams and rivers.
