Salt Lake City and the Wasatch-Cache National Forest are preparing to trade land in a widespread exchange in which holdings between City Creek Canyon and Parleys Canyon would be consolidated.

"For many years these lands have been managed as a `checkerboarded' land-ownership pattern, with both entities having lands scattered throughout each canyon," says a joint announcement by District Ranger Richard P. Kline and Salt Lake Public Utilities director Leroy W. Hooton Jr.City and national forest land have been managed to meet the common objective of protecting critical watersheds, while allowing sound multiple uses where possible. The objective will remain the same after the swap, if it takes place.

The primary objective of the land exchange would be to improve management efficiencies through consolidation of ownership, officials said.

Salt Lake City's ownership consolidation would be mainly in the City Creek and Mountain Dell areas, where it already manages water treatment plants, reservoirs and recreation sites. The Forest Service would consolidate land in the Red Butte Research Natural Area, Emigration Canyon and Parley-Lambs canyon drainage.

Forest Service officials must prepare an environmental analysis of the plan and need public comments by Sept. 30. They should be mailed to the Salt Lake District Ranger, Wasatch-Cache National Forest, 6944 S. 30th East, Salt Lake City, UT 84121.
