This report has been in progress since 2014. It covers two related field concerns on a graded lot: keeping small children on the correct side of a slope, and the slower, quieter problem of a house that treats "foundation" as more of a suggestion.
Coming this spring. Every spring. It's been eleven springs.
Keep Kids Safe
The recommended approach is a "no cross" line — a clearly marked boundary a safe distance from the grade, intended to prevent what field researchers have termed a roll 'n' tumble (RNT). Full placement guidance, materials list, and signage templates are still in review.
My House Is Sliding…
Now what? That's the report. We're working on it. In the meantime, the working theory is that a house on a 41% grade is less "built" and more "currently in transit," and any movement should be logged, not panicked about.
