Every reasonable effort should be made to preserve
archeological resources at or near any project.
Additions of an appropriate contemporary design are
acceptable if they do not destroy the essence of the
Alterations should be designed to allow their removal at
the end of the life cycle. This removal should not damage
the essence of the historic resource.
Demolition of historic resources, or moving of
archeological resources, should be coordinated with the
SHPO and the ACHP. The minimum action will be formal
documentation of the significant asset as it sits in
In some instances, partial demolition is appropriate when
an alteration of no historic significance is hiding a more
significant feature. Again, coordination with the SHPO
will generate good feedback on properly executing the
2.3.2 Mitigating. The basic legal requirement of Section 106
of the NHPA is for the Navy to "take into account" in the early
stages of planning, prior to approval for expenditure of project
funds, what effect its actions might have on National Register
resources (listed or eligible for listing) and to afford the ACHP
a reasonable opportunity for review. When it is determined that
an undertaking will have adverse effects on a historic resource,
mitigation measures should be developed to lessen the impact of
the undertaking to the point where it is an acceptable price to
pay for the benefits of the undertaking.
2.3.3 Appropriateness/Design Issues. The design solutions
chosen for additions, modifications, and demolitions to (and
near) a historic or archeological resource, should exhibit the
same enduring style as the significant resource. Sensitivity and
consideration are of key importance.
2.3.4 Sites, Outbuildings, Grounds. These historic
properties typically require little or no maintenance as they are
lesser developed resources than the primary historic property.
These types of properties may be an undeveloped site within a
historic district, a shack or building on or adjacent to a
historic property, or the grounds surrounding a historic
building. The objective in maintaining these properties is to
protect and preserve the distinctive features and materials of
grounds, sites, outbuildings, and other elements that might be an
important part of the property's history and development.
