On each new channel project, except a grassed waterway constructed for the purpose of conveying runoff without causing erosion or flooding, a vegetative strip shall be established and maintained for a width of 50 feet immediately adjoining the channel on each side of the stream if site conditions permit, unless an acceptable engineering design shows that a greater or lesser width of vegetative strip is preferable.
The general type of vegetation shall be approved by the chief engineer.
