Characterize Type A soils in terms of infiltration rates and runoff potential.

Type A soils are characterized by their high infiltration rates and low potential for runoff. These soils typically include well-graded sands and gravels that have a high permeability, allowing water to easily infiltrate into the soil rather than pooling on the surface. As a result, they are effective at absorbing precipitation, which minimizes the likelihood of runoff occurring. This property is especially beneficial for various land uses, as it helps reduce erosion and sediment transport while maintaining water quality.

The combination of high infiltration and low runoff potential is critical in managing stormwater and mitigating the impacts of erosion, particularly in construction and land development projects. Understanding the behavior of Type A soils is essential for designing effective sedimentation and erosion control measures.
