The U.S. Forest Service Lake Tahoe Basin Management Unit, in coordination with Heavenly Mountain Resort, issued a draft decision for proposed improvements to existing skiing and snowboarding terrain at the resort. They found that the projects would cause no significant negative impacts. Proposed improvements would include selective widening of ski trails, removing trail obstacles and relocation and/or realignment of some portions of existing snow making air and water pipelines to improve user experience, maintain user safety, increase energy and water efficiency, and maintain native species. The proposal to remove trail obstacles was addressed in the Heavenly Ski Resort Master Plan and includes protection of native plants and re-vegetation, removal of invasive plants, chipping of large woody debris and existing felled trees, stump grinding, and boulder height reduction. Project work could begin as early as spring/summer 2018.
