IMPACTS OF IMPLEMENTING ALTERNATIVE 3

OPERATIONS

Park Operations

Under alternative 3 existing buildings and facilities would remain and some may be adaptively used for new functions and uses. Development of new frontcountry trails, closure of a portion of Rim Drive to two- way traffic, and adaptive use of historic structures for visitor use would increase the level of maintenance required to support these new visitor activities. Year- round residences at Steel Circle and summer season residences at Sleepy Hollow at Munson Valley would continue to be maintained. Park maintenance staff would continue to maintain park roads, utilities, and structures. The Munson Valley Road to Rim Village would continue to be cleared of snow during the winter months, and Rim Drive would continue to be plowed to allow summer access as early in the spring as weather dictates.

Most park functions would remain in the park. Staff functions would shift to a greater emphasis on resource protection and interpretation. There would also be an increased need for maintenance operations to maintain expanded front country trails and visitor services. Changes in park operations would be perceptible but would not be expected to have an overall detrimental effect on the ability of the park to provide desired services and facilities, resulting in minor, adverse impacts to park operations.

Cumulative Impacts. Past facility development, particularly at the rim, has affected park operations. Ongoing actions, including scaling back development at Rim Village and improving parking and circulation, have impacted park operations. Overall these projects have the potential to have a moderate long- term beneficial effect on park operations and improvement in the ability of the park to provide desired services and facilities. Impacts of the above other actions in conjunction with alternative 3 would result in moderate long- term beneficial cumulative impacts. Alternative 3 would contribute a minor adverse increment to cumulative impacts to park operations. Conclusion. Alternative 3 would result in minor, adverse impacts to park operations. Cumulative actions in conjunction with alternative 3 would result in moderate long- term beneficial cumulative impacts. Alternative 3 would contribute a minor, adverse increment to cumulative impacts to park operations.

Concession Operations

Relative to the no- action alternative, there would be a change to concessioner activities under alternative 3. There would be a moderate, long- term, beneficial impact on concession operations. Increased partnering with commercial operators would provide for additional opportunities.

Cumulative Impacts. Past actions, including restoration of the Crater Lake Lodge, and ongoing actions, such as reconfiguration of park facilities at the rim and at Mazama Village have had an impact on concessioner activity. Consolidation of concession activity at Mazama and the closeness of Mazama Village to Oregon State Highway 62 would facilitate concession operations and inventory staging, resulting in readily apparent changes in concession operations that would have a long- term, moderate, beneficial impact on concessioner operations. Impacts of the above other actions in conjunction with alternative 3 would result in an overall moderate, longterm beneficial cumulative impact. Alternative 3 would contribute a moderate, beneficial increment to cumulative impacts on concession operations.

Conclusion. Alternative 3 would result in a moderate, long- term beneficial impact on concession operations. Cumulative actions in conjunction with alternative 3 would result in an overall moderate, longterm, beneficial cumulative impact. Alternative 3 would contribute a moderate beneficial increment to cumulative impacts on concession operations.
