Rehabilitation of Highway 62 West, Crater Lake National Park, Klamath County, Oregon

 ENVIRONMENTAL CONSEQUENCES

ALTERNATIVE B: RESURFACING, RESTORATION, AND REHABILITATION

This section evaluates the potential impacts of alternative B.

Cultural Resources

Archeological Resources

There are historic-period archeological sites associated with segments of the Fort Klamath-Jacksonville wagon road located in the vicinity of the project corridor. The location of these sites, however, lies outside of the area of potential effect for this alternative. There are no known archeological resources at the Pacific Crest trailhead parking lot, the area around turnout B, and a turnout to the west of Whitehorse Crossing, and therefore, no impacts are anticipated. At Whitehorse Creek and the switchback area, all known archeological resources would be avoided. Therefore, there would be no impacts to archeological resources under alternative B.
Should previously unidentified archeological resources be discovered during construction, work in that location would stop until a qualified archeologist could inventory and evaluate the resource and appropriate measures could be implemented, either to avoid further resource impacts or to mitigate their loss or disturbance in consultation with the Oregon SHPO.

Cumulative Impacts. In conjunction with all past, present, and reasonably foreseeable future actions, including trail rehabilitation and relocation, the reconstruction of the Rim parking lot, the waterline replacement from Munson Springs to Garfield, the lagoon project at Munson Valley, and rehabilitation of the superintendent’s house; implementation of alternative B would not contribute to cumulative impacts to archeological resources.

Conclusion. Alternative B would have no impact on archeological resources and would not contribute to cumulative impacts.

Because there would be no major adverse impacts to a resource or value whose conservation is (1) necessary to fulfill specific purposes identified in the park’s establishing legislation, (2) key to the natural or cultural integrity of the park or to opportunities for enjoyment of the park, or (3) identified as a goal in the park’s General Management Plan or other relevant National Park Service planning documents, there would be no impairment of park resources or values.

Section 106 Summary. Under alternative B, all road work would be confined within the existing roadbed and previously disturbed areas. After applying the Advisory Council on Historic Preservation’s criteria of adverse effect (36 CFR 800.5), the National Park Service proposes that implementing alternative B would result in a determination of no historic properties affected.

Historic Structures

Although Highway 62 West crosses, covers, and parallels the Fort Klamath-Jacksonville wagon road in several locations, the rehabilitation of the roadway would not create any new impacts to the wagon road, and therefore, no impacts are anticipated. At turnout A and the switchback area, all known resources would be avoided. Therefore, there would be no impacts to historic structures under alternative B.

Cumulative Impacts. In conjunction with other past, present, and reasonably foreseeable actions, including trail rehabilitation and relocation, the reconstruction of the Rim parking lot, the waterline replacement from Munson Springs to Garfield, the lagoon project at Munson Valley, and rehabilitation of the superintendent’s house, alternative B would not contribute to cumulative actions.

Conclusion. Alternative B would have no impact on historic structures and would not contribute to cumulative impacts.

Because there would be no major adverse impacts to a resource or value whose conservation is (1) necessary to fulfill specific purposes identified in the park’s establishing legislation, (2) key to the natural or cultural integrity of the park or to opportunities for enjoyment of the park, or (3) identified as a goal in the park’s General Management Plan or other relevant National Park Service planning documents, there would be no impairment of park resources or values.

Section 106 Summary. Under alternative B, all road work would be confined within the existing roadbed and previously disturbed areas.
