Mitigating Flood Impacts and Rehabilitating Infrastructure

For more than a century, chronic flooding had been an issue in Salem’s Canal Street area, which serves as one of the primary entry points into the City and the Salem State University Campus. This problem has been exacerbated by recent development in the floodplain that has increased the rate of stormwater runoff in this centrally located portion of the City’s downtown business district. Working with us, they obtained $4.6 million in FEMA grants to implement an infrastructure improvement project to mitigate future flooding.

We worked with the City to develop a comprehensive stormwater management strategy and undertake measures that would maximize the capacity of the existing stormwater system, along with defining new drainage infrastructure options to mitigate chronic flooding. Our team recommended a flood mitigation program that included reconstructing the City’s drainage collection system within the watershed and constructing a new 10,000 gallons-per-minute pumping station and a new 4 million gallon underground stormwater storage facility within Salem State University campus.  The project also included rehabilitation of existing municipal-owned sewer and water system infrastructure and privately owned infrastructure within the project area as well as reconstruction of athletic fields and facilities at a drainage system outfall located on Salem Harbor. A portion of the infrastructure improvements were constructed in 2014 with the remainder to occur in 2017.

Hazard mitigation planning to prevent future flooding

With a complete Hazard Mitigation Plan in place, we assisted the City to secure an initial $3 million in FEMA grants in 2013 and an additional $1.6 million in grant funding a year later for upgrading critical stormwater infrastructure.
