What the mapped data shows

The USDA map unit associated with this Broken Arrow record is Dennis-Pharoah complex, 1 to 3 percent slopes. Its listed component is Dennis, with drainage reported as somewhat poorly drained. These labels describe an area on a survey map. Conditions can change within a lot and may be altered by grading, imported fill, construction, or drainage work.

For this record, the Plasticity Index is 16.5 and the registry screening class is Moderate. The recorded PI of 16.5 indicates some potential for moisture-related volume change. Drainage and site history remain important when interpreting symptoms.

How to interpret this for a home in Broken Arrow

A mapped screening class is context, not a diagnosis. Two houses in the same map unit can perform differently because of roof runoff, plumbing leaks, tree placement, slope, foundation design, and previous repairs.

Document where water collects after rain, photograph cracks with dates and a ruler for scale, and note changes in doors, windows, trim, and floors. If symptoms progress, property-specific measurements can help determine whether movement is active, historic, or cosmetic.

What this report cannot tell youSurvey data does not establish bearing conditions beneath the house or the correct repair system, quantity, or depth. Those questions require property-specific evidence.

What a sound evaluation should establish

  • Is movement active? Compare dated symptoms and repeat measurements.
  • Is water contributing? Review grading, drainage, irrigation, and plumbing.
  • What supports the proposed scope? Ask how the repair design follows from measurements and site conditions.
