Impacts to ROWs and corridors would result from management actions that limit, prohibit, or increase the potential for ROWs and include the management of ROW avoidance/mitigation and exclusion areas, ROW corridors, and resource specific restrictions and stipulations on surface-disturbing activities and ROW authorizations. ROW avoidance/mitigation and exclusion areas would both result in adverse impacts by prohibiting or limiting the development of ROWs and potentially resulting in additional constraints, mitigation, and other stipulations. ROW avoidance/mitigation and exclusion areas are the greatest under Alternative B (2,943,367 acres), followed by Alternative D (2,551,205 acres), Alternative C (1,182,097 acres), and Alternative A (1,003,194 acres). Alternative A includes the most area allocated for ROW corridors (788,275 acres) which would reduce the potential for resource conflict and additional mitigation or modification of ROW facilities, followed by Alternative C (133,284 acres) and D (132,219 acres), with Alternative B allocating the least (90,458 acres). Restrictions on surface-disturbing activities resulting from management of resources and special designations would be greatest under Alternative B. Overall, Alternative C has the lowest level of constraints applied to ROW authorizations and may result in the greatest number of new ROWs and communication sites. Alternative B includes the most constraints that would limit or prohibit ROW authorizations and would result in the least number of new ROWs and communication sites.
