ABSTRACT: The Port Lands Flood Protection and Enabling Infrastructure (PLFPEI) Project is a $1.25 billion program that will revitalize 800-acres of flood prone land. In connection with the Port Lands Flood Protection Enabling Infrastructure project, a grade raise is proposed along Commissioners Street and Don Roadway to protect local neighbours from floodwaters from the Don River in the event of extreme weather. A new fill of up to about 4m in height will be placed to raise the existing grade within the right of way of the roadways. Due to the extensive thickness of compressible peat and organic soils, significant settlement of the foundation soils is anticipated. Following a comprehensive review of different design alternatives to control the post-construction settlement of the foundation soils supporting the embankment to an acceptable limit, ground improvement utilizing a rigid inclusion method was chosen as the preferred option. This paper presents the results of the foundation investigation program, design methodology, performance specifications, load transfer mechanism, and the results of settlement monitoring of the embankment during and following construction.
