I-80/Gilman Interchange Improvement
Lead Agency:
Caltrans District 04/FHWA
Location:
Berkeley, CA
Deliverables:
Area of Potential Effect, Historic Resources Evaluation Report, Department of Parks and Recreation Forms (District; Building, Structure, Object)
Duration:
February - June, 2017
Objective:
Evaluate built environment and assess impacts for interchange project.
Summary:
Ten historic-period resources were identified and evaluated for National Register and California Register eligibility. These resources, which span 15 parcels and 23 addresses, consist of nine built environment resources and one historic-period archaeological deposit. Several of the built environment resources consist of multiple buildings that occupy more than one parcel and addresses. One one resource, the California Ink Company Complex, was recommended eligible. The historic-period archaeological deposit qualifies for evaluation exemption under the Caltrans Programmatic Agreement (PA) with the California Office of Historic Preservation, Federal Highways Administration, and the Advisory Council on Historic Preservation. Submitted to Caltrans District 4. Project deliverables have been completed on time and within budget.
Umpqua National Forest Site Evaluation
Lead Agency:
Umpqua National Forest
Location:
Douglas County, Oregon
Deliverables:
Prehistoric Site Evaluation and Finding of Effect
Duration:
July 2018 - February 2019
Objective:
Evaluate prehistoric site for National Register eligibility and impacts associated with the Umpqua North Fire Complex suppression activities.
Summary:
Evaluation included archaeological excavation of 5 cubic meters, resulting in:
- 42 flaked obsidian, chert, and basalt tools
- 4902 pieces of obsidian, chert, and basalt debitage
- 4 groundstone manuports
- 142 faunal bone specimens
These materials indicate an indigenous group used this location for habitation, plant, textile working, and tool maintenance. Although projectile point types and carbon-14 dates indicate the site was occupied from 2000 to 200 years ago, occupation was probably not limited to this period alone.
