Why are there bags around the catch basins (drains) causing the street to flood?
In new areas and in construction zones, stormwater inlets (catch basins) on the streets are often protected with socks or bags to reduce the amount of sediment that enters the storm sewer system that drains directly to the Bow River. This is a requirement from Alberta Environment to protect the water quality of our river systems. Sediment from construction sites can have a significant impact on the water quality of the river. Although this can be annoying for people living in the area or driving on the road, this small inconvenience is worthwhile if it helps to improve water quality. It is unlawful to remove these devices. They will be removed once construction in the area is no longer tracking mud onto the streets.
