Calgary unveils 2.4-km Sunnyside flood barrier ahead of flood season

Calgary has unveiled its new 2.4-kilometre Sunnyside flood barrier along Memorial Drive, a major infrastructure project designed to protect the area from a 1-in-100-year flood. The barrier was formally introduced on Thursday and was built to prevent the Bow River from breaching as it did in 2013. City officials say it marks the strongest level of flood preparedness Calgary has ever achieved, arriving just as the city enters its annual flood season from mid-May to mid-July.
