CRUMB AND GRANULAR SOIL STRUCTURE - Soils which have crumb or granular structure shall be considered _______________as to structure.

Crumb and granular soil structure indicates many small, rounded aggregates with open, interconnected pores. This pattern provides good permeability and drainage, so effluent can infiltrate rather than pond. In septic system terms, soils with this structure support effective percolation and distribution in the drainfield, making them favorable and thus considered suitable. (Less favorable structures, like massive or compacted clays, would not have the same infiltration characteristics.)
