OAR 629-630-0905: Western Oregon Harvesting; Standard Practice; Designated Debris Flow Traversal Areas

(1) For Western Oregon, operators shall not harvest timber located in designated debris flow traversal areas. (2) Operators shall retain all trees within 25 feet slope distance from either side of the active channel, or center of the draw if no channel is present for areas identified by the slopes model as designated debris flow traversal areas. (3) Changes in stream classification for a stream, based on field surveys for fish-use consistent with OAR 629-635-020 0, shall not change the department’s maps used for notifications of operations that identify designated debris flow traversal areas. (4) Operators shall submit a written plan, described in OAR 629-630-0925, for timber harvest units containing designated debris flow traversal areas. (5) Cable yarding, which may require cutting, but not removal, of trees, is permitted through designated debris flow traversal areas, but the number, size, and location of yarding corridors shall be designed to minimize impacts to the integrity of designated debris flow traversal areas. The operator shall not remove trees cut for yarding corridors unless these are deemed safety hazards.
