<br />O~2553 <br /> <br />Table 8 <br />Acres of natural-appearing landscapes by alternative <br /> <br />ALTERNATIVE <br /> <br />B C 0 E F I <br />1,710,000 1,834,000 1,686,000 1,971,000 1,580,000 2,008,000 <br /> <br />Each management area has a range of SILs. The SILs vary by alternative based on the <br />management areas assigned to it The result is a range of SIL maps depicting very high <br />SIL (unaltered iandscapes) to very low SIL (heavily altered andscapes). When the final <br />Forest Plan is approved, these SILs will become scenic integrity objectives that will serve <br />as a guide for design and implementation of management activities. <br /> <br />Infrastructure and Travel Management <br /> <br />Infrastructure. Most revision alternatives propose a reduction in the size of the Forest <br />Road Development Transportation System. Alternative I reduces the road system the <br />most from its current level of 2,356 miles to 1,676. The extent of the road system <br />increases from this level in Alternatives C, D, E and B. Alternative F proposes the largest <br />road system at 2,409 miles and is also the only alternative that will have a road system <br />greater than the current level. <br /> <br />New road construction levels are anticipated to be lower than 1984 Forest Plan <br />projections for all alternatives. Most new construction is expected from timber <br />management activities, with Alternative F producing the most new miles in the planning <br />period. Road reconstruction varies by alternative and may actually increase above <br />current levels to bring roads into compliance with new standards and guidelines. <br /> <br />Obliteration and recontouring of roads identified for decommissioning will occur in all <br />alternatives~Alternative I obliterates the most roads at 996 miles, and Alternative F <br />obliterates the fewest roads at 269 miles. Depending on funding, the actual completion of <br />this work will take from 18 to 31 years. <br /> <br />Travel Management. Summer and winter issues vary significantly across the Forest <br />the travel management topic was developed to address both. The analysis for travel <br />management has gone into greater detail than many previous forest plans in order to <br />create a site-specific travel management plan for the entire Forest for each alternative. <br />One portion of the travel management decision will determine which, if any, areas will be <br />available for off-road motorized and/or mechanized travel. Figure 10 displays the extent <br />of the Forest where off-road vehicle travel will be available by alternative. <br /> <br />Every inventoried road and trail has been mapped and travel management strategies for <br />each proposed alternative are listed in Appendix 0 of the DEIS. The miles of roads and <br />trails open to motorized travel, which varies considerably by alternative, is of great <br />interest to the public and a significant travel management issue. Figure 11 displays the <br />total miles of roads and trails on which motorized travel will be designated. <br /> <br />-- 33 - <br />
