Geologists and students:

I want to personally invite you and your colleagues to the October 16, 2014 AEG-BWH meeting featuring Joe Cavey of Hayward Baker and Jim Guinther, of Whitman, Requardt & Associates. Their talk concerns the collapse of the 26th Street retaining wall in Baltimore that was captured on cell-phone video. This dramatic event was seen on You-Tube and all of the TV News
channels. Every geologist should know be familiar with this very public issue and the actions taken to fix our crumbling infrastructure. The meeting is at Brewer’s Alley in Frederick. Please register immediately. Below is the notice.

TOPIC: Emergency Retaining Wall Replacement, 26th Street, Baltimore, MD

After significant rainfall in Baltimore City on April 30, 2014, the
retaining wall between 26th Street and the CSX tracks collapsed. 26th Street was closed between Charles Street and St. Paul Street while the roadway was stabilized, utilities were replaced, and construction began for a new
retaining wall. The project consisted of constructing a temporary soldier pile and lagging wall with 3 rows of anchors. Between the temporary support of excavation and the railroad tracks, a new gravity retaining wall will be constructed. The presentation includes discussion of the technical aspects of the emergency response, the geotechnical design and the construction of the replacement wall.
