How is a temporary storm drain diversion recommended to be set up in terms of inlet protection?

Setting up a temporary storm drain diversion with inlet protection is best executed as part of a combined approach that includes both primary and secondary controls. This strategy enhances the overall effectiveness of erosion and sediment control by providing multiple layers of defense against sediment-laden runoff.

Inlet protection serves to prevent sediment from entering the storm drain system, which can lead to potential impairments in water quality and increased maintenance needs for the drainage system. When inlet protection is used in conjunction with a secondary control, such as sediment barriers or silt fences, it can significantly reduce the risk of runoff carrying sediment away from the site and into stormwater systems or nearby water bodies.

This integrated method ensures that if one control measure fails or becomes overwhelmed by heavy rainfall, the other can still function to manage sediment runoff effectively. It exemplifies the principle of redundancy in stormwater management practices, which is key to maintaining compliance with regulations and protecting environmental resources.
