Case Study: Geotechnical Site Characterization for the I-35W Stormwater Storage Facility
Publication: Geo-Congress 2020: Modeling, Geomaterials, and Site Characterization (GSP 317)
ABSTRACT
The Minnesota Department of Transportation (MnDOT) studied a variety of stormwater storage facility (SSF) concepts to mitigate flooding events along Interstate 35W (I-35W) in Minneapolis near 42nd Street South. After evaluation of these concepts a deep storage structure with lift station concept located on the shoulder of I-35W northbound between 42nd Street South and 40th Street South was selected. The project area is located near the edge of a glacial erosional channel between glacial deposits and bedrock. The investigation informs the understanding the geology and geotechnical aspects of the site and supports a geotechnical data report (GDR) and a geotechnical interpretive report (GIR). The investigation included a variety of methods including geophysical multichannel analysis of surface waves (MASW); standard penetration test geotechnical borings; in situ instrumentation with vibrating wire piezometer nests; multiple rotosonic borings; and a pump test. The paper presents an overview of the investigation and findings and how these results informed preparation of the GDR and GIR documents.
