to how and why concentrated flooding occurred in these areas of the City. It was determined that the flooding in Ward 1 flooding was largely as a result of stormwater entering the sanitary system while the flooding in Ward 9 was largely related to overland stormwater flooding.

After investigating the conditions of the City’s storm sewers, ditches, wastewater treatment plants, pumping stations and retention treatment basin it was determined that the City’s infrastructure operated to capacity as designed.

The report contains some short-term recommendations for Council’s consideration that, once implemented, will assist with alleviating future instances of significant basement flooding.
