Located along the Connecticut and Westfield Rivers, the majority of West Springfield’s flood protection system was constructed between 1939 and 1942. The Riverdale Section was constructed in 1950 and provides protection along US Route 5—a major thoroughfare and business district. The Westfield River section protects a densely populated residential and industrial area as well as the Eastern States Exposition Fairgrounds.
Benesch provided design and full-time, on-site construction engineering and inspection services associated with Army Corps of Engineers- and FEMA-mandated improvements to the system. Repairs encompassed the removal of vegetation from approximately 13,700 feet of earthen dike and structural repairs to approximately 2,300 feet of concrete floodwall along the Connecticut and Westfield Rivers. The flood protection system also includes three Stop-Log structures, six pumping stations and appurtenant drainage structures and facilities. Structural, electrical and mechanical repairs were made to the pump stations to ensure proper function. Repairs were also required at appurtenant drainage structures and facilities.
Benesch is currently conducting quarterly inspections of the system to maintain its integrity. The scope of work includes a detailed visual inspection of the dike embankment and Flood Wall System, Stop-Log Systems and appurtenant structures, Toe Drainage Systems and other items to observe and document conditions. A Final Condition Survey Report is being prepared. Maintenance services are being performed as needed.
