Swannanoa, NC
Affordable Communities Group

Click here to view photo full-screen

A 2018 landslide caused by a failed retaining wall closed a primary access road to a residential community and threatened an aging water main essential to the community’s water supply system. To repair and mitigate future risk, the project team developed a pioneering geotechnical stabilization design consisting of reticulated micropiles and tiebacks. The strategy proved more economical than conventional approaches and allowed the road to remain open while minimizing risk until the threat of additional slides were remediated.

Catonsville, MD
American Rivers

Click here to view photo full-screen

A century-year-old, 34-foot-high Bloede Dam on Maryland’s Patapsco River was safely demolished to restore the river to its natural state. The dam also had become a bane to the region’s health and safety as nine people had died there since the 1980s. The project team designed a passive release strategy for removal of 300,000 cubic yards of impounded dam sediment, while adding a new 42-in-diameter sanitary sewer line to replace an outdated 12-inch cast-iron siphon.
