In the summer of 2014, a high-intensity rainfall in Cambridge surcharged the city’s stormwater drainage system, resulting in localized flooding near a basement-level retail space. The floodwaters overtopped the sidewalk and flowed down the entryway stairs, inundating the retail space and causing significant damage. SGH investigated the circumstances surrounding the damaging flood event and developed a strategy for mitigating future flooding.
