The heavy rain this week forcing the evacuation of 12 people from a Saint John apartment building and contributing to a mudslide near Hartland.
Chief City Planner Ken Forrest warning the new members of Common Council these types of weather events will be happening more often because of climate change.
Part of the heavy rainfall this week was caused by Tropical Storm Debbie which deluged parts of Florida with 600 millimeters of rain.
Forrest says drainage of storm water in parts of Saint John leaves much to be desired at the best of times.
