Abstract
Eastern Washington University has initiated the Palouse Prairie Restoration Project, transforming 120 acres of campus land back into native habitat. This effort is designed to increase biodiversity, expand opportunities for outdoor recreation, create real-world research experiences for students, and support outdoor learning environments, which includes infrastructure development. Our soil sample, PP‑14, was collected from the top of a slope within the Palouse Prairie site to help understand how engineering properties of soil change along slopes in the project area. Other groups sampled soil from the mid slope and slope base for comparison. We followed ASTM standards to determine soil properties like specific gravity, particle size distribution, optimum water content for compaction, and unconfined compressive strength. The results of these tests are compared with mid-slope and slope-base samples.
