Project Updates
August 20th, 2024 - In Summer 2024 work on the Greenleaf St. necessitated a closure of the Emerald View Trail wrapping around the northwestern end of Mount Washington. The trail will remain closed until the completion of the remediation work in November of this year.
In September 2024 work on the William St. site will necessitate a 5 day closure of PJ McCardle Roadway between Grandview Avenue and the Liberty Bridge. The road will be closed between 5:00am Wednesday September 4th to 7:00pm Sunday September 8th, 2024 in order for contractors working on the Williams St. Landslide Remediate Project to clear debris from the hillside. Drivers are encouraged to use Boggs, Saw Mill Run and the Liberty Tunnel as an alternate route during this time.
Project Background
The Mt. Washington Landslide Mitigation project is a City of Pittsburgh Department of Mobility and Infrastructure (DOMI) lead effort with the support of the Federal Emergency Management Agency (FEMA) and the Pennsylvania Emergency Management Agency (PEMA) to preemptively secure the hillsides of Mt. Washington to minimize the probability of a landslide events. In recent times, the Mt. Washington area has been challenged in several areas where hillside instability has spilled debris onto roadways and walking paths.
Press Conference announcing Climate Resilience Mitigation Projects
There are three principle “areas” of Mount Washington to be addressed in the project:
- Greenleaf St (parallel to PA State Route 51/19)
- Reese St (on the Northern face, below the CBS radio transmission tower)
- William St (above and parallel to Arlington Avenue and PJ McArdle Roadway)
Greenleaf Street is East of Saw Mill Run Boulevard (SR 51/19). The Reese St site is South of West Carson Street
In 2018, a large landslide on Greenleaf Street spilled significant debris onto Saw Mill Run Blvd causing substantial traffic impacts.
The Reese Street site is located on the hillside beyond the end of the street and below the CBS radio Tower. Slope movement threatens to impact the Emerald Park Trail. Further mitigation solutions are needed to ensure long-term slope stability.
William Street above Arlington Avenue and P.J. McArdle Roadway.
In recent years, there have been several landslides along the length of William Street which have caused closure of the road and condemnation of one house. The City has been monitoring the hillside and seeks to develop further mitigations to stabilize the slope, reduce future impacts to additional residential properties, and limit debris from falling onto McArdle Roadway and Arlington Avenue.
