Document Description
The purpose of this Project is to restore the roadway stability of a segment of Morgan Territory Road to its predisaster
capacity following slope failure caused by storm events. The Project consists of constructing a new
retaining wall structure, road improvements, erosion control measures, and drainage improvements. A soldier
pile wall with an anchorage system will be installed to stabilize the roadway embankment and prevent
continued erosion into Marsh Creek. A drainage inlet and pipe will be installed to improve drainage behind the
retaining wall. The existing 42-inch corrugated steel pipe culvert that runs under Morgan Territory Road will be
replaced with a 42-inch reinforced concrete pipe. Riprap will be placed on both sides of the replaced culvert to
prevent scour. Vegetation and tree removal (approximately two trees) will be required to access the
construction site and install the soldier pile wall. Construction will require earthwork equipment, including
excavators, loaders, and compactors, which will operate primarily from the roadway.
Real estate transactions, including sliver right-of-way acquisitions and temporary construction easements
(TCEs), will be necessary. Construction is anticipated to begin in Spring/Summer 2027. Work will take place
during the dry season and will require approximately 50 working days. Temporary traffic control, including
partial roadway closures and short-duration full roadway closures, will be required during construction. Limited
nighttime work may be necessary to minimize traffic disruptions during peak travel periods. Appropriate best
management practices for water pollution control will be implemented to protect the creek. Applicable
regulatory permits will be obtained before construction.
