Village and Inglewood, sits on the flood plain of the Bow River. Infrastructure is in place to mitigate flooding in Sunnyside but the risk of flood damage remains. A berm along Memorial Drive and the Bearspaw Dam upstream provide some protection but proved not enough in June 2013. The berm was breached in two areas and the Bearspaw Dam was too far upstream and the reservoir storage capacity too small to prevent this large flood. In 1932, Sunnyside experienced widespread flooding. In June 2005 when exceptionally heavy rainfalls combined with the regular rise in the Bow River caused by snow melting in the mountains. Storm sewer outflows were closed off to prevent the Bow River from flooding the neighbourhood, leaving the heavy rainfall to collect in the neighbourhood. The result were some basement flooding and parts of Memorial Drive being closed to traffic. In March 2009, a similar incident occurred when heavy wet snow that fell overnight melted quickly during the day. With the outflows once again closed off, this time to prevent flow in from the Bow River that could occur from winter ice dams, the water flowing down from Rosedale quickly accumulated in Sunnyside. Several homes on 1 Ave NW between 5A Street NW and 6 Street NW experienced basement flooding. On June 20 to 24 2013, Sunnyside was impacted by the 2013 Alberta floods. Three factors contributed to the flooding: 1. High river flow of the Bow River increasing the water table level and the Bow River flowing into Outfalls that hadn't been closed in time or couldn't be closed. 2. Intense rain that fell in the neighbourhood in a short period of time 3. Storm Sewer that flowed from other neighbourhoods into Sunnyside. On July 5, 2013, Sunnyside was impacted again by flooding. This time the cause was intense rain that fell in the neighbourhood and the fact that storm sewer outfall gates were closed and did not provide enough opening to release the water. Architecture Sunnyside's architecture is a mixed array of designs and styles each telling a story of the neighbourhood's history. Sunnyside has a blend of single-family dwellings, modern mid-rise high-density housing, neighbourhood corner stores and restaurants and walk-up apartment buildings. In the 1880s, the Canadian Pacific Railway constructed “workers’ cottages" on 25-foot lots, which they rented to CPR employees. The cottages were wood framed and had cellars that were prone to flooding.
