Area of Potential Effects, Historic Properties Inventory, Finding of Effect, Treatment Plan, Monitoring Report


April 2018 - June 2018


Repair to bridge that suffered structural damage from Spring 2018 storm events.


InContext facilitated consultation among Merced County, the ACOE, the California State Historic Preservation Officer (SHPO), Caltrans District 10, the Native American Heritage Commission, the Northern Valley Yokuts Tribe, the environmental permitting subcontractor, and the engineering contractor to complete the required Historic Properties Inventory and Finding of Effect document two days after execution of contract for work. SHPO concurrence was received on April 20, 2018. This consultation negotiated the definition of the APE and the ADI, the determination of eligibility for the purpose of the emergency repair project, agreement regarding the project’s potential to impact the archaeological site, and mitigation measures to protect the site during implementation of the repairs. Mitigation was carried out alongside the repair construction seven days after contract was executed. Documentation of successful mitigation was provided to the ACOE the day after the repairs were completed (May 5, 2018). Final report documenting mitigation was delivered on June 8, 2018 with no edits or comments from the ACOE. InContext completed the project under budget.

Historic Resources Evaluation Report


February 2017 - June 2017


Improve automobile and pedestrian safety of interchange.


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.

Lead Agency:     U.S. Army Corps of Engineers, San Francisco District


Location:           Napa, California


Deliverables:     Research Design, Data Recovery Report


Duration:           March 2017 - August 2020


Objective:         Implement data recovery excavation of the prehistoric village mound (CA-                             NAP-928) as stipulated in Memorandum of Agreement and Historic Properties                           Treatment Plan agreed upon between the U.S. Army Corps of Engineers and                             the California State Historic Preservation Officer.


Summary:          Data recovery was implemented as directed by the MOA and HPTP. A crew of                           20 archaeologists (including 2 osteologists, 2 lithic specialists, and 1 faunal                             specialist) was mobilized to work on a rotating schedule over the course of                             12 months. The site yielded a total of 175 features and 105 burials. Analysis                           of the materials has been completed and the Final Interim Data Recovery                               Report was approved by the COE in August 2020. 



Umpqua National Forest


Douglas County, Oregon


Prehistoric Site Evaluation and Finding of Effect


July 2018 - February 2019

Evaluate prehistoric site for National Register eligibility and impacts associated with the Umpqua North Fire Complex suppression activities. 


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 processing, 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.
