Background

The Department of Mobility and Infrastructure (DOMI) is remediating 10 identified landslides in Riverview Park. These can be seen on the map below. The methods of doing so have included soil nails, beam and concrete walls, and grading and benched the ground and slopes.

These 10 landslides can be identified on this park map by numbers. Remediation of landslides marked 8,9, and 6 have been completed. Landslide 6 just finished as of 8/22/25. Remediation on landslides 1 and 3 are set to begin on 8/25/25 and end on 11/7/2025 although this timeline is subject to shift, if needed. The remaining five landslides (2, 4, 5, 7, and 10) are being monitored, and remediation will begin once funding is identified.

(Question continued) If so, what species are involved. What soil type is involved? Has overgrazing contributed to the landslides/erosion?

Replanting is part of the project. Each slide is evaluated and a separate landscaping plan is developed and provided to the City of Pittsburgh Forester for review.

The grass proposed for the current Slide S6 is in accordance with Pennsylvania Department Of Transportation Specifications Publication 408 seeding and soil supplements Formula B, D, and E.

The tree replanting includes Sugar Maples, River Birches, American Sycamores, Scarlet Oak, Pin Oak, Silver Lindens, Kousa Dogwood, Star Magnolias, White Pines, Japanese Black Pines, and Dawn Redwoods.

Overgrazing is unlikely to be a contributing factor as to the cause of the landslide. The park is home to typical animals found in park settings such as deer, rabbits, and squirrels, but does not support the agricultural type animals that are traditionally associated with grazing. The landslide is likely the product of drainage at the site and the underlying soil type. The Pittsburgh area is susceptible to landslides due to underlying clay red beds and claystone. When moist or saturated, it is prone to creating a failure plane.
