Monitoring of Dickson Road slide in Sewickley continues
Monitoring of a landslide-prone area of Dickson Road has shown part of the land slightly moved.
Over a three-month period, engineers reported that Dickson Road has slipped one-eighth of an inch, borough manager Kevin Flannery said this week.
“But it's fine,” he said. “There's no real issue there.”
In December, engineer Joe Boward told residents of Dickson Road, and Farren and Miller streets their properties were located in an “ancient landslide area” that has been sliding for “at least a couple thousand years.”
Flannery said no homes are in immediate danger; only the road appears affected.
A multi-tiered retaining wall with extensive site grading could solve the issue, but that could cost as much as $15 million, according to an engineer's report.
A more cost-effective plan could involve stabilizing with soldier pile and lagging walls in two particular areas of concern — one on Miller Street and another at a hairpin turn at Dickson Road and Miller.
Costs for those two projects could be more than $300,000, according to a report.
The hillside will continue to be monitored, and officials are expected to determine this spring how water is flowing nearby.
