8-521.A. Site Location and Design. The applicant shall show that the proposed development is either located in a site free from avalanche danger or is adequately protected by avalanche defenses or structural provisions.

8-521.B. Access. No development shall be accessible only by crossing dangerous active avalanche paths.

8-521.C. Removal of Vegetation. The development shall not result in timber clear cutting or other large scale removal of vegetation in avalanche hazard areas. Alteration of plant cover which would decrease the stabilizing effect shall be prohibited, especially on slopes above the proposed development. Where any alteration of vegetation cover is allowed, revegetation shall be initiated promptly and provisions ensuring seedling protection, including an acceptable irrigation plan, shall be enforced until seedlings are large enough to stabilize the snow cover.

8-521.D. Extractive Operations. Extractive operations shall not be conducted in historic or high hazard avalanche areas during winter without an adequate program of avalanche control and defense measures.

8-521.E. Utilities. Utility lines or pipes crossing historic avalanche areas shall be buried underground, and surface pipes and poles or towers for suspended transmission lines in historic avalanche areas shall be adequately protected by avalanche diversion or direct protection structures.

8-521.F. Roads for Winter Use. Roads intended for winter use shall avoid avalanche hazard areas.

8-521.G. Temporary or Seasonal Uses. Building restrictions may be modified for construction of underground utilities such as water reservoirs or for temporary buildings used only in non avalanche season and either removed or protected in the winter.

8-521.H. Warning Signs. Warning signs of avalanche danger shall be placed along roads and trails that are commonly traveled in winter where they cross avalanche paths characterized by high frequency of activity.

8-521.I. Artificial Release. Artificial release of avalanche by explosive control or artillery shall not be considered an acceptable mitigation technique for areas of potential human occupancy.
