Commission accepts Alta survey for Mendocino septic repair, orders archaeological monitoring west of residence and cultural‑awareness training

The Mendocino County Archaeological Commission on Jan. 8 accepted an archaeological survey prepared by Alta Archaeological Consulting for CDP 2024‑0013 and adopted archaeological conditions recommended in the report, including focused monitoring on the west side of the residence and cultural‑resources awareness training for construction supervisors and crews.

Shelby Miller, staff planner, said the applicant submitted the requested ARC survey; agent Megan Durbin summarized why the survey was completed after an earlier hearing and described the contractor’s plan. “The survey that was submitted was the survey that was completed. There was a shell refuse site … to the west of the property,” Durbin said, and noted Alta’s recommendation that monitoring be required for ground‑disturbing activities between the resource and the west side of the house. Durbin added that the applicant intends to relocate the leach field to the east and limit disturbance toward the shell feature.

Commissioners and tribal representatives discussed monitoring scope and who would conduct monitoring. Valerie (Sherwood Valley tribal representative) said the project lies within traditional territory and emphasized tribal monitoring practice, including attendance at safety meetings and limited, careful handling of cultural materials. Commissioners agreed the report’s recommendations should be implemented. The commission motioned to accept the Alta survey and add the report’s conditions (referenced in the meeting as pp.14–16 of the report) and carried unanimously: Commissioner Cole — yes; Commissioner (unnamed) — yes; Commissioner Johnson — yes; staff — yes.

The adopted conditions require an archaeological monitor for ground disturbance occurring between the shell‑refuse resource and the west side of the residence, and the report’s recommended protocols for “unanticipated discoveries” and the county’s discovery clause. Durbin and consultants discussed a cultural‑resources awareness training to be administered by a professional archaeologist and distributed as a pamphlet to construction personnel; the training will explain how to stop work and notify key personnel if cultural materials are encountered.

Megan Durbin told the commission the applicant’s goal was to limit monitoring to the west side of the house to manage project costs while addressing cultural‑resource risk. The commission also confirmed that monitoring will be performed by a professional archaeologist as recommended in the report, and commissioners asked staff to coordinate referrals and any tribe‑requested additional monitoring arrangements.

The action implements the Alta report’s monitoring plan and the county’s standard discovery clause; staff will include the report conditions in the permit approval and inform the applicant and monitoring parties of the commission’s requirements.
