The ground in Fox Chapel

Fox Chapel is a heavily wooded borough of large lots on steep ravine terrain above the Allegheny River. Long driveways descend wooded hillsides, and walls here often hold driveway cuts and house benches on slopes threaded with springs. The combination of deep ravines, colluvial soil, and mature tree cover makes drainage the first question on almost any wall project in the borough.

The bedrock story is the same across the metro: weak red-bed claystone that loses strength when wet, under a slow-creeping blanket of colluvium. Walls doing real structural work are a common sight around the Fox Chapel Road corridor, the hillsides above Route 28, the Trillium Trail area and the Beechwood Farms area. The landslide guide explains why that combination deserves respect.

Wall age in Fox Chapel

Walls age like the houses they came with. If a wall here is leaning, bulging, or shedding material, the failing wall page covers what an assessment looks for, and the hillside page covers slopes that are moving with or without a wall.
