When soil forms flat, plate-like layers close to the surface, it disrupts how water moves through the profile. Platy structure reduces pore connectivity, slows infiltration, and can create perched water, especially when these plates occur within the upper portion of the soil. For septic systems, reliable infiltration is essential, and having platy structure within 36 inches of the natural surface means the soil is unlikely to absorb and distribute effluent effectively. That’s why it’s classified as unsuitable as to structure. The other options would imply some level of suitability or require additional conditions, but near-surface platy structure provides insufficient infiltration capacity, so the correct determination is unsuitable.
