660-006-0025 Uses Authorized in Forest Zones (1) Goal 4 requires that forest land be conserved. Forest lands are conserved by adopting and applying comprehensive plan provisions and zoning regulations consistent with the goals and this rule. In addition to forest practices and operations and uses auxiliary to forest practices, as set forth in ORS 527.722, the Commission has determined that five general types of uses, as set forth in the goal, may be allowed in the forest environment, subject to the standards in the goal and in this rule. These general types of uses are: (a) Uses related to and in support of forest operations; (b) Uses to conserve soil, air and water quality and to provide for fish and wildlife resources, agriculture and recreational opportunities appropriate in a forest environment; (c) Locationally-dependent uses, such as communication towers, mineral and aggregate resources, etc; (d) Dwellings authorized by ORS 215.705 to 215.757; and (e) Other dwellings under prescribed conditions. (2) The following uses pursuant to the Forest Practices Act (ORS chapter 527) and Goal 4 shall be allowed in forest zones: (a) Forest operations or forest practices including, but not limited to, reforestation of forest land, road construction and maintenance, harvesting of a forest tree species, application of chemicals, and disposal of slash; (b) Temporary on-site structures that are auxiliary to and used during the term of a particular forest operation; (c) Physical alterations to the land auxiliary to forest practices including, but not limited to, those made for purposes of exploration, mining, commercial gravel extraction and processing, landfills, dams, reservoirs, road construction or recreational facilities; and (d) For the purposes of section (2) of this rule “auxiliary” means a use or alteration of a structure or land that provides help or is directly associated with the conduct of a particular forest practice. An auxiliary structure is located on site, temporary in nature, and is not designed to remain for the forest’s entire growth cycle from planting to harvesting. An auxiliary use is removed when a particular forest practice has concluded.
