Abstract:

For more than 50 years manufacturing plants adjacent to the northeast bank of a midwestern creek produced asbestos-reinforced construction materials. When manufacturing at the plants ceased in 1979 the asbestos material was covered in place and closed. Through channelization and urbanization of the regional watershed over many decades, the creek has eroded and scoured the stream banks, resulting in the exposure of the asbestos-containing material along the northeast bank. Environmental Resources Management (ERM), St. Louis, MO, was hired to complete the remedial action plan and design a retaining wall and slope revetment to stabilize erosion along the entire bank. The stabilization design involves a retaining wall with H-pile steel beams and concrete lagging�one of the longest freestanding retaining walls ever designed and built in the Midwest�as well as a cabled concrete bank revetment.
