SR-138 / High Desert Corridor Testing

Cogstone began work on this project by conducting Extended Phase I (XPI) testing where project-related subsurface disturbances were proposed and conducting an intensive-level pedestrian survey. Subsequently, Cogstone was retained to write the narrative Historic Property Survey Report, revise the prior Archaeological Survey Report and Historical Resources Evaluation Report, and prepare a combined Paleontological Identification Report/Paleontological Evaluation Report. Twelve archaeological resources that were not located in the original survey were all relocated by Cogstone.
