What is Negative Grading at Walkout Basements?
Negative grading is soil that slopes TOWARD the foundation instead of away from it. Code requires 6 inches of fall in the first 10 feet from the wall.
What do we find on Roseville inspections?
Owasso Hills and North Oaks walkouts on natural slope toward the lake are repeat offenders. Decades of mulch top-offs and settled soil at downspouts create reverse grading.
What should you do about it?
Re-grade with 6:10 fall. Extend downspouts ≥ 6 ft from the foundation. Drain-tile retrofit if persistent.
How this connects to other Roseville defects
Era-defects rarely show up in isolation. A 1965 Roseville rambler that has one of these almost always has two or three more from the same construction window. Our defect library documents the full set we look for, and the inspection report cross-references findings so you can see the pattern.
