Block-Like Soil Structure with peds 1 inch or smaller is considered what as to structure?

Soil structure and how the peds form a blocky pattern directly affect how quickly water can move through the soil. When peds are 1 inch or smaller and the structure is block-like, the pore spaces that enable rapid infiltration are reduced, which tends to slow drainage. That makes the site less than ideal, but not a clear disqualification. In this system of classification, such a condition is labeled provisionally suitable because it signals a potential limitation that could be managed with design modifications or additional testing. For example, infiltration tests or adjustments to drain-field design (like increasing area, using deeper placements, or employing alternative trenches) might confirm that the system can still function adequately. If the soil showed extreme limitations with no practical way to mitigate them, it would be unsuitable; if there were enough evidence showing adequate infiltration without changes, it would be suitable; and if there wasn’t enough information to judge, it would be unclassified.
