The St. Paul flood control project was completed in 1964 to protect one of the main industrial areas of the city from flooding of the Mississippi River. Riverview Industrial Park, the area protected by the project, has undergone extensive development ranging from manufacturing plants to commercial establishments and financial institutions. Since development of the project, St. Paul experience major floods in 1965 and 1969, both of which exceeded the previous record flood in 1952. The purpose of this study is to determine the present needs for flood control in the project area and whether the project meets those needs. The specific study area consists of the lands, buildings, and improvements protected by the existing flood barrier. This report contains recommendations on the economic feasibility, environmental acceptability, and advisability of modifying the project or its operation due to changed economic and hydrologic conditions.
