City of Mississauga Looks Ahead to Flood Prevention and Mitigation

Sep 11, 2013

At today's General Committee meeting, staff presented flood mitigation and process improvement recommendations based on the July 8, 2013 storm when the City of Mississauga experienced unprecedented rainfall that overwhelmed the storm drainage system's capacity.

"Flooding is a terrible experience and in response to the recent storm, we will proceed with a number of short and medium term actions to improve our emergency response plans and processes, and review the effectiveness of our public infrastructure," said Martin Powell commissioner of Transportation and Works. "We have received a letter from the Ministry of Municipal Affairs and Housing regarding our application which states that the City of Mississauga is not eligible for funding under the Ontario Disaster Relief Assistance Program (ODRAP). The recommendations made today will help us better plan and manage the risk of flooding. The City is looking for opportunities to strengthen its stormwater system and reduce the risk of damage from flooding events in the future."


Recommendations in the General Committee report included:

• Establish a capital project for Cooksville Creek erosion control between Burnhamthorpe Road East and Mississauga Valley Boulevard.
• Review the City's Emergency Plan with partners.
• Build a new stormwater management facility for the Cooksville Creek in 2014.
• Construct Cooksville Creek Crossing and Flood Protection works at King Street East and Paisley Boulevard East in 2014.
• Commence a Flood Evaluation Study for Serson, Applewood and Little Etobicoke Creeks in 2014.
• Create an advisory panel to provide insight, advice and guidance on flooding related studies being undertaken or planned by the City as a result of
the July 8, 2013 storm.
• Waive building permit and inspection fee for a backwater valve for all homeowners in the City of Mississauga.
• Report back to General Committee in early 2014 with an update on the progress of actions undertaken in response to the July 8, 2013 extreme rainfall event.

In addition, Mayor Hazel McCallion put forward an amendment that included three additional recommendations.

• That the Credit Valley Conservation, Toronto and Region Conservation, City of Mississauga and Region of Peel put together a report gathering the projects that are required to be undertaken on a priority basis and the capital budget implications as well as operating budget implications.
• That the legal department advise Council of the liability, if any, if a permit is issued for a basement apartment.
• That the Credit Valley Conservation and Toronto and Region Conservation confirm to Council that the stormwater management of Brampton is acceptable due to the fact that it could have a major impact on the Etobicoke Creek and Cooksville Creek.

These recommendations will come forward to Council for final approval on Wednesday, September 18, 2013.

More information on the recommendations is available in the corporate report: July 8, 2013 Storm Event Update – Transportation and Works.

"We are still gathering information from residents about the storm effects and causes, working with our partners on flood response - the Region of Peel, Credit Valley Conservation and the Toronto and Region Conservation," said Powell. "During the storm the City staff’s priority was ensuring public safety and responding to situations as requested by Emergency Services. Response included road closures and the emergency repair of damaged public infrastructure. After the storm, the City undertook watercourse inspection of affected creeks, road repairs, clean up and removal of debris and storm sewer inspections."

He also stated that planning is well underway for the priority capital projects identified in 2011 through the work of the Cooksville Flooding Task Force. These and other recommended works were given master plan environmental assessment approval by the Province of Ontario in 2012. This allowed design to begin on the most critical projects, meaning that construction can start next year pending budget approval by Council.

Powell urged residents and businesses who have not reported flooding from the July 8th storm to do so by contacting the Region of Peel at 905-791-7800 ext. 4409 or the City's 3-1-1 Citizen Contact Centre. This will assist in determining the specific causes of flooding and potential improvement measures. For more information visit the City of Mississauga's July 8, 2013 flood information webpage.


Ontario Disaster Relief Assistance Program (ODRAP)
On July 30, Council received a report entitled Ontario Disaster Relief Assistance Program Application and passed a resolution requesting that the City of Mississauga, or part thereof, be declared a disaster area. Council also passed an additional resolution that Council waives the building permit fee for the installation of backwater valves for residents affected by the flood on July 8, 2013. See attached resolutions.

In a resolution signed on Friday, July 26th by acting mayor Nando Iannicca, the City requested disaster relief funding from the Ministry of Municipal Affairs and Housing through the Ontario Disaster Relief Assistance Program (ODRAP). For complete details, please refer to the corporate report.

Flood Response
Flood response involves the City, the Region of Peel and the local Conservation Authorities.

The City of Mississauga is responsible for managing stormwater in its jurisdiction. The Region of Peel is responsible for regional roads, drinking water, wastewater and solid waste management.

Conservation authorities are responsible for flood forecast and warning, watershed management and floodplain regulation.

Stormwater Program
The City's stormwater program includes the management of the physical system (storm sewers, curbside drains, stormwater management ponds, bridges and culverts), including stream rehabilitation, flood mitigation works, maintenance and rehabilitation of existing infrastructure, environmental compliance, emergency response and clean up, street sweeping and bylaw enforcement.

As Canada's sixth largest city, Mississauga is home to 741,000 residents and more than 54,000 businesses, including more than 60 Fortune 500 companies with Canadian head offices or major divisional head offices. A diverse, progressive and award-winning municipality located on the shores of Lake Ontario in the heart of the Greater Toronto Area, Mississauga is "Leading Today for Tomorrow" by focusing on delivering services, implementing its Strategic Plan, delivering value for money and maintaining infrastructure.
