What the mapped data shows
The USDA map unit associated with this Boerne record is Tarpley clay, 1 to 3 percent slopes. Its listed component is Tarpley, with drainage reported as well 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 28.6 and the registry screening class is High. The recorded PI of 28.6 makes moisture sensitivity worth considering alongside property-specific evidence. This is a screening signal, not proof that a foundation is moving.
How to interpret this for a home in Boerne
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 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.
