This USACE project involved the removal of existing railroad tracks, excavation and removal of the existing toe drain system that was located under the railroad tracks, installation of a new toe drain system, and reconstruction of the railroad subgrade and tracks in a confined space in an around the clock operation in August 2016. Work was completed during the mandatory 72-hour railroad shutdown. The major aspects of the work included excavation, pipe demolition, pipe installation, manhole installation, and subgrade construction. A separate portion of the project took place in November 2016 and involved excavating around and exposing existing sheet piling, cutting the sheet piling off at design grade, and installing a flowable fill sheet pile cap that tied the sheet piling into the floodwall.
