The ground in Ross Township

Ross is classic North Hills terrain: ridgetop corridors along Perry Highway and Babcock Boulevard dropping into steep ravines that drain to Girty’s Run and Pine Creek. Hillside streets, benched building lots, and walls holding driveways and backyards are everywhere, and the red-bed claystone that underlies much of the North Hills makes wet-season movement a recurring theme.

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 Perrysville, Laurel Gardens, Evergreen Hamlet and the Girty’s Run valley. The landslide guide explains why that combination deserves respect.

Wall age in Ross Township

Ross filled in through the postwar decades, and many of its hillside plans date to the 1940s through 1960s. Across Allegheny County, 28.1 percent of homes predate 1940 and the median build year is 1957 (US Census ACS 2020 to 2024 five-year estimates).

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.
