SOIL GROUP I - Sandy Texture Soils. The sandy group includes the sand and loamy sand soil textural classes and shall be considered ________________________ with respect to texture.

Sandy texture soils have features that align with favorable infiltration needs for drainage fields. Sand and loamy sand have large pore spaces and high hydraulic conductivity, so they drain quickly and allow effluent to infiltrate without standing water or clogging the treatment zone. When classifying soils by texture for this purpose, these coarse-textured soils are considered suitable with respect to texture. This designation reflects the texture’s ability to support rapid infiltration and drainage, though other site factors (like depth to groundwater, bedrock, or slope) still matter for overall suitability. They’re not deemed unsuitable or unclassified, and the texture alone doesn’t justify labeling them provisionally suitable.
