Commission debates when ground disturbance triggers referral to Northwest Information Center

The Archaeological Commission spent its final agenda time discussing draft parameters for what constitutes ground disturbance that should prompt referral to the Northwest Information Center (NIC).

Planner Mark Klieser told commissioners that the county currently refers discretionary permits that include ground disturbance to NIC; if NIC recommends no further survey, the item is not scheduled for ARC review, but if NIC recommends additional surveys it is scheduled. Klieser said the county is seeking clearer thresholds, including whether small amounts of excavation (the code cites about two cubic yards) or numerous fence post holes should trigger referral.

Commission discussion reflected differing views. Some commissioners and staff said placing a heavy storage container with no excavation should not require referral. Others raised that repetitive, distributed disturbance (for example, many fence post holes across acres) could amount to substantial disturbance. Klieser noted that two cubic yards is the numerical reference already in county code. Several commissioners said they had seen many recorded sites nearby and questioned how NIC evaluates parcels; staff said NIC bases recommendations on past studies in the area and invited NIC to present to ARC.

Valerie Stanley of the Sherwood Valley Tribe emphasized that cultural resources are priceless and asked whether heavy sheds or capping methods damage sites; she offered to help request NIC attendance. Jesse Waldman (Planning) acknowledged that a NIC letter arrived after an earlier packet on one permit and recommended NIC attendance to explain their processes. Planning staff said they would attempt to invite NIC for a briefing and consider clarifying referral thresholds in county policy.
