improvements, including new trail or road construction
• Prescribed burns and vegetation management
• Climate change
5.4.4.2 Impact Criteria (Cultural Resources)
• Beneficial Impact: Impact that would occur if a planning element results
in enhanced visitor awareness regarding the fragile and irreplaceable
nature of cultural resources, or if opportunities for public interpretation of
cultural resource sites are implemented. There is no CEQA equivalent to a
NEPA beneficial impact.
• No Impact: Impact that cannot be detected.
• Minor Adverse Impact: Impact to a cultural resource that does not qualify
as a historic property, historic resource, or unique archaeological resource.
This is equivalent to a CEQA less than significant impact.
• Adverse Impact: Impact that would occur if a proposed undertaking results
in a Finding of Adverse Effect to a Historic Property in accordance with
Section 106 or significant impact to a historic resource or a unique
archaeological resource. An adverse impact is equivalent to a CEQA
significant impact, which would result from one or more of the following:
− A prehistoric or historic archaeological site or property of historic or
cultural significance to a community or ethnic social group;
− A prehistoric or historic archaeological site determined to be an
“important archaeological resource” as defined in the State CEQA
Guidelines;
− A property that is listed or eligible for listing on the California
Register/National Register; or
- Any human remains, historic or prehistoric, including those interred
outside of marked formal cemeteries.
In the event a significant cultural resource (historic property), as defined by the
NRHP criteria; an historic resource, as defined by CRHR criteria; or a unique
archaeological resource, as defined by CEQA; is identified that may be affected
by future projects, the potential for impacts (effects) will be taken into
consideration, and measures to avoid the resource will be considered. In the event
the resource cannot be avoided, it would be resolved (36 CFR Section 800.6)
through the resolution of adverse effect as spelled out in either a MOA or a PA
executed by the federal agency and SHPO. The resource would be subject to
mitigation measures such as data recovery, further study, enhanced recordation,
interpretation, physical protection, or some combination of these measures.
5.4.4.3 Environmental Evaluation
Unauthorized Collection and Vandalism Under all alternatives, existing
visitor uses have some potential to disturb or destroy cultural resources,
particularly those that are not documented. The action alternatives include
additional features or facilities in the Plan Area that would accommodate or
support increased visitor use. Increased visitation, or visitation to parts of the Plan
