Flooding in the community of Lakeview has been a frequent and recurring problem. Like many older neighbourhoods in Calgary, Lakeview’s drainage system did not meet current service level expectations for stormwater drainage.

As a result, recurring road flooding, sewer surcharge/backup and property flooding occurred during major storms.
