Friday is the U.S. Forest Service deadline for accepting written comment on a proposal for new lift and base-area development at Brighton Ski Area in Big Cottonwood Canyon.

Written comments should be submitted to Richard P. Kline, district ranger of the Wasatch-Cache National Forest, Salt Lake Ranger District, 6944 S. 30th East.A preliminary Forest Service report, called a scoping document, summarizes the Brighton proposals, identifies some issues and concerns and presents alternatives.

The proposals include replacing the Mary lift with a longer quad lift, building two new lifts for novice skiers and relocating the ski school. Snow-making machinery would be added along the length of the Majestic run and the upper third of the Dick Knight run.

The Forest Service will incorporate public comment into an environmental assessment before any decision on the proposal is made.

In March, the Salt Lake County Planning Commission voted to delay a decision on the proposed development until the Forest Service completes its environmental assessment, and until the county completes its master plan regulating future canyon development.

A preliminary draft of the canyon master plan is scheduled to go to a citizens advisory committee next week for review. The county hopes to adopt a final version of the plan late this year.

Big Cottonwood Canyon residents and environmentalists have opposed the project, claiming expansion at Brighton will mean more skiers, more commercial development, increased traffic congestion and environmental damage to the canyon.
