APPROPRIATION / PHASE: Continuing Authorities / Feasibility

BUSINESS PROGRAM: Flood Damage Reduction

AUTHORITY: Section 14 of the Flood Control Act of 1946, as amended: Emergency Stream Bank Stabilization.

LOCATION: The study area is River Road along the Schuylkill River in North Coventry Township, Chester County, Pennsylvania.

DESCRIPTION: The project site is located along the right bank of the Schuylkill River parallel to River Road between the Pennsylvania State Route 100 and Hanover Street Bridges in North Coventry Township, PA.  The proximity of the steep River Road embankment to the Schuylkill River at this location contributes to the continual erosion of the river bank eventually resulting in undermining the road shoulder and ultimately the road, exposing the existing utilities to failure and motorists to the potential danger of driving off the embankment. River Road also provides the only local access to the residential community of South Pottstown. Closure of this local road would force local residents to use U.S. Route 422 adding seven miles to their daily commute.

The project consists of bank stabilization of the right bank of the Schuylkill River along River Road between Laurelwood Road and the Hanover Street Bridge. The river bank would be stabilized using a combination of riprap and vegetative cover in a bio-engineering solution known as longitudinal peak stone toe protection (LPSTP) for a total length of about 1,000 feet. An analysis of alternatives and coordination of an environmental assessment will also be required prior to any construction.

PROJECT GOALS: The purpose of this project is to protect motorists, pedestrians and exiting utilities by stabilizing the existing eroding stream bank and shoulder of River Road which runs along the Schuylkill River in North Coventry Township, Chester County, PA. High river flow events combined with the steep embankment conditions at the site pose a threat to public safety along the road alignment. 

STATUS: A Project Partnership Agreement (PPA) with the Non Federal Sponsor needs to be executed for the design and construction of the project.  Upon execution of the PPA all design and environmental permit compliance activities necessary for construction will be completed. Environmental activities will include PADEP permits and coordination with the Chester County Soil Conservation District. Engineering tasks will include geotechnical characterization of the project site, final project design, and a detailed cost estimate followed by award of the construction contract.
