Division 623 - SHALLOW, RAPIDLY MOVING LANDSLIDES AND PUBLIC SAFETY
Section 629-623-0400 - Restriction of Timber Harvesting - Substantial Public Safety Risk

(1) Operators shall not remove trees from high landslide hazard locations with substantial downslope public safety risk unless a geotechnical report demonstrates to the State Forester that any landslides that might occur will not be directly related to forest practices because of very deep soil or other site-specific conditions. Removal of dead or diseased trees or trees from sites that have already failed is allowed if the operator demonstrates to the State Forester that the operation results in no increased overall downslope public safety risk.

(2) Operators shall leave a sufficient number and arrangement of trees adjacent to high landslide hazard locations to reduce the likelihood of trees retained in these locations blowing down.
