Section Env-Wt 902.31 - Stream enhancement

"Stream enhancement" means the manipulation of the physical, chemical, or biological characteristics of a stream, or any combination thereof, undertaken to heighten, intensify, or improve one or more specific stream functions, where the work does not qualify as total stream restoration because it does not result in a gain of natural stream reach. The term includes but is not limited to in-stream or stream bank stabilization activities that restore one or more of the natural riverine attributes such as dimension, pattern, or profile.
