Streambed regrading after material removal, if required, shall leave behind an undulating surface topography outside of the low-flow channel as similar to naturally formed topography in the project area as possible, so that the resulting surface depressions expose the shallow water table and maximize potential for colonization by riparian trees. Features such as channels and pools maximize the diversity of environmental conditions for the establishment of riparian habitat, and are therefore encouraged. (as amended by Ord. 1518, eff.
