Hwy 62 – 71 Soils and Geology

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

 ENVIRONMENTAL CONSEQUENCES

ALTERNATIVE A: NO ACTION

This section evaluates the potential impacts of the no-action alternative.

Soils and Geology

The no-action alternative would leave the road within the existing road alignment and in its current condition. There would be no change to soils and geology from the no-action alternative.

Cumulative Impacts. Past, present, and reasonably foreseeable future actions that would have an effect on soils and geology within the park include the waterline replacement from Munson Springs to Garfield and the lagoon project at Munson Valley. The adverse effects of these projects would result in long-term, localized, adverse, cumulative impacts. The no-action alternative would not contribute to these actions.

Conclusion. There would be no change to soils and geology from the no-action alternative. The no-action alternative 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 related to soils and geology at Crater Lake National Park.
