In the event that a division of land or any part thereof is traversed by any major watercourse, channel, stream or creek, the subdivider shall dedicate an adequate right-of-way for storm drainage purposes if, in the opinion of the Advisory Agency, such dedication is necessary. In the event that the natural watercourse does not lie entirely within such dedication, the subdivider may either construct an adequate channel within such dedication or delineate the course of the watercourse upon the final map, or parcel map as may be approved by the county engineer. These waterways shall be maintained in a natural condition.
