What is the maximum drainage area for a temporary asphalt berm?

The maximum drainage area for a temporary asphalt berm being set at 1.5 acres emphasizes the purpose of ensuring that the accumulated runoff is manageable and does not lead to erosion or overwhelming sediment control issues. In the context of erosion and sediment control practices, limiting the drainage area helps maintain the effectiveness of the berm by preventing excessive water accumulation, which can compromise its structural integrity and the effectiveness of sediment control measures.

By establishing this threshold, regulatory guidelines aim to minimize the risk of erosion during construction activities by ensuring that the temporary structures in place can handle the expected volumes of water. This standard demonstrates a thoughtful balance between construction site needs and environmental protection, ensuring temporary measures can adequately function under anticipated conditions.
