Section 3.13. Cultural Resources
Full-Tidal Alternative
The Dickson Ranch is eligible for listing in the NRHP and the CRHR with a
local level of significance under NRHP Criterion A and CRHR Criterion 1, for its
association with events of importance including the development of agriculture
and reclamation in the bay lands. Implementation of the Full-Tidal Alternative
would have similar effects as discussed above for the Project would result in the
although the area where archeological resources could potentially be encountered
is greater. Damage to or destruction of the Dickson Ranch complex, resulting in a
loss of a historic property. This would constitute any such resources would be a
significant impact on the site. Mitigation Measure CR-MM-2CR-1 would be
implemented; however, and it would not reduce the impact to a less-thansignificant
level.
Mitigation Measure CR-MM-3: Document the Dickson Ranch
SLT shall hire a qualified cultural resources management specialist to document
the Dickson Ranch with a historical narrative and large-format photographs in a
manner consistent with the Historic American Buildings Survey (HABS). Copies
of the narrative and photographs would be distributed to branches of the Sonoma
County Library system, Sonoma County Historical Society, and other appropriate
repositories in the area. The preparation of the HABS documentation will follow
standard National Park Service procedures. There will be three main tasks:
gather data, prepare photographic documentation, and prepare written historic
and descriptive reports. The photographic documentation will consist of largeformat
photography conforming to HABS standards. Photographic
documentation will include 4- by 5-inch negatives in labeled sleeves, 8- by 10-
inch prints mounted on labeled photo cards, and an index to the photographs.
Research will also include possible photographic reproduction of any available
building blueprints.
Conclusion: Less than Significant and Unavoidable Impact. with Mitigation.
Impact CR-2: Destruction of Significant Historic
Resource (Dickson Ranch)
The Proposed Project has the potential to remove or affect several structures at
the project site. These resources are the Dickson Ranch, Black Point Sport Club,
Sonoma Valley Railroad Grade, Northwestern Pacific Railroad Grade, and the
perimeter levee and drainage ditches, and the well.
The evaluation by Tom Origer & Associates (2010a) of the historic resources
found that that none of the resources were eligible for inclusion on the NHRP or
the CRHR. As described above in the Historic Architectures and Structures
section of this section, the USFWS has evaluated the project site and found the
field survey and records search is in compliance with Section 106 requirements
and determined that the Project would have no effect on historic properties (Tom
Origer & Associates 2010a; USFWS 2011d). The impacts are considered less
than significant, and no mitigation is required.
