Cascade GIS conducted an archaeological survey in the Columbia River Gorge National Scenic Area (CRGNSA) for a client applying for a re-plat near The Dalles, Oregon, in Wasco County. Because it was located in the General Management Area (GMA) of the CRGNSA and because it qualified as a “large-scale use” under the CRGNSA Management Plan, the project was subject to commplex regulatory requirements including an archaeological reconnaissance survey. Cascade GIS worked with the Gorge Commission, SHPO, and the County to complete the project under a short time-frame to ensure the client’s timely application to the County. Several sites and isolates were identified and recorded, including an NRHP-eligible late-1800s occupied rockshelter. Cascade GIS used data driven pages to efficiently satisfy the 1:1200 scale mapping requirements of the CRGNSA Management Plan.

The Scenic Area Act authorizes the Gorge Commission and the Forest Service to protect cultural resources by using guidelines and the Open Space designation. The guidelines must require new commercial and residential uses, mineral operations, and other types of development to occur without adversely affecting cultural resources. – CRGNSA Management Plan
