Is inlet protection recommended as a secondary control in conjunction with a temporary storm drain diversion?

In the context of erosion and sediment control, the effectiveness of various methods can greatly depend on the specific site conditions and the overall implementation of sediment control strategies. When dealing with temporary storm drain diversions, the need for additional protective measures is essential for minimizing sediment entry into drainage systems.

Inlet protection is often utilized as a primary control measure to prevent sediment from entering into an existing storm drain. However, when implementing a temporary storm drain diversion, the functionality of the existing inlets changes significantly. The storm drain diversion is designed to redirect water flow, and the occupancy of these inlets by sediment, which inlet protection would be intended to prevent, may not be as critical if these inlets are not receiving direct flow during this temporary setup.

The answer suggests that incorporating inlet protection as a secondary control in conjunction with a temporary storm drain diversion is not typically recommended, as the diversion itself should be effective enough to manage sediment displacement without additional inlet protection measures. Instead, other strategies may be prioritized to ensure that the overall site is managed effectively for sediment control without overwhelming the inlet protections, which might not function as expected in this unusual context.

This understanding reinforces a strategic approach to erosion and sediment control rather than simply applying multiple protective measures without consideration of their interaction
