What is required when construction vehicles cross a live watercourse more than twice in any six-month period?

When construction vehicles are required to cross a live watercourse more than twice in a six-month period, a temporary vehicular stream crossing constructed of non-erodible material is necessary. This requirement is in place to ensure that sedimentation and erosion are minimized and that water quality in the stream is protected.

Using non-erodible materials for the crossing helps to stabilize the area and reduces the disturbance to the streambed and banks, which is crucial in preventing increased turbidity and sedimentation in the waterway. This practice aligns with the goals of erosion and sediment control by maintaining the integrity of the watercourse while allowing for necessary construction activities.

Constructing a permanent bridge may be an option for frequent crossings but is not the standard requirement for temporary crossings as mandated by ESC regulations. Submerged floating platforms and accessing only from the bank do not adequately address the need for a defined crossing that can mitigate the environmental impact associated with vehicular traffic over watercourses. Selecting a temporary crossing made of appropriate material ensures compliance with best management practices in erosion control during construction phases.
