Document Description
Removal of portions of a failed retaining wall that has fallen into the creek, and replacement of the failed wall with a new retaining wall. The project also includes restoration and minor expansion of a parking lot beyond an existing curb at the edge of the existing paving. In 2005, the concrete retaining wall was undermined and collapsed as a result of heavy creek flow during winter storms. The project involves installing sheet pile in the same location and alignment of the collapsed concrete wall to prevent further bank erosion, and backfilling the area behind the sheet pile wall. To execute removal of the failed concrete wall which is now within the creek channel, "hand" tools such as a wall saw unit and/or jackhammers would be used to break portions of the failed wall into a few smaller pieces. Then, the smaller pieces of the collapsed wall would be excavated with a crane situated from the top of bank.
