Surficial Geology

This data set depicts unconsolidated soil and residual, and colluvial and alluvial materials that lie above bedrock. Surficial material or overburden generally displays different characteristics with respect to load-bearing capacities and ease of excavation than the consolidated bedrock at lower elevations, with higher load-bearing capacities generally occurring in consolidated formations and greater ease of excavation generally occurring in materials above this surface. The information can be used in a general way to interpret potential issues related to infrastructure development.
