True or False: A diversion or earthen dike is required to direct stormwater into a temporary slope drain.

A diversion or earthen dike is necessary to guide stormwater into a temporary slope drain to effectively manage and control erosion and sedimentation during construction or land disturbance activities. The main purpose of these structures is to intercept and redirect surface water runoff, ensuring that it flows into designated drainage systems rather than allowing it to flow uncontrolled over the surface. This practice minimizes the erosive potential of stormwater by preventing concentrated flows that can lead to significant soil loss and sediment transport.

By directing stormwater into a temporary slope drain, the water can be safely managed and diverted to where it can either be temporarily stored, treated, or discharged without causing harm to the surrounding environment or infrastructure. This is especially important in areas where construction activities may disrupt the natural flow of water, making proper diversion essential for maintaining site stability and protecting water quality.

Therefore, the statement is true because using diversions or dikes is an integral part of effective stormwater management practices.
