Flood Watch Issued for Lake Ontario Shoreline

The averaged Lake Ontario elevation for yesterday (Toronto, Apr-30-2019) was at 75.41 metres (m) above International Great Lakes Datum (IGLD).  Today, the lake elevation is near 75.46 m.  Flood damages in 2017 occurred at a Lake Ontario elevation of 75.45 m when waves generated during a storm event overtopped and damaged several shoreline structures.  The latest forecast (Apr-30-2019) provided by the Lake Ontario St Lawrence River (LOSLR) Board of the International Join Commission (IJC) is projecting maximum Lake Ontario elevations ranging from 75.65 to 75.95 m for late May to Early June with the upper range being 2 centimetres above the record set in 2017.  The lake damage threshold elevation of 75.45m does not account for wave generated by winds which can increase flood elevations and cause additional damages; this is especially true with onshore winds associated with storms.

Information provided by the Surface Water Monitoring Centre (SWMC) of the Ministry of Natural Resources and Forestry (MNRF) along with the IJC is indicating that rain and snow melt within the Great Lakes and St Lawrence River basin have resulted in high river and lake levels.  Major flooding is currently (Apr/May, 2019) occurring in Eastern Ontario and Quebec due to a combination of high flows in the St Lawrence and Ottawa River. 

The current Lake Erie water elevation is at a new record high for the-end-of-April.  Flows discharging from Lake Erie via the Niagara River, over the Falls, into Lake Ontario are uncontrolled.  Flows discharging out of Lake Ontario into the St Lawrence River are controlled at the Moses-Saunders (MS) Dam.  The MS Dam is operated in accordance to Plan 2014 from IJC which takes into consideration, and balances, the impacts of downstream flooding with higher Lake Ontario levels.  Over next several weeks, Lake Ontario levels will increase and will remain high for the season due to high inflows from Lake Erie and restricted Lake Ontario outflows to mitigate downstream flooding along the St Lawrence and Ottawa Rivers.

Onshore winds, especially those associated with storms systems, can generate waves resulting in shoreline erosion, flooding and damages.  Wind and wave conditions are provided by Environment Canada via the following website:

CVC will continue to monitor weather and lake conditions.  This Flood Watch will be updated by Fri-Jun-14-2019

Watercourses discharging directly into Lake Ontario may be impacted by backwater from the lake.  Residents and visitors to the Lake Ontario shoreline areas should use extreme caution and obey all closure notices for trails and pathways.  As lake levels increase, certain areas may be cut off or isolated. 

Flood Watch Issued for Lake Ontario Shoreline

There is a Flood Watch currently in effect for Mississauga.

Lake Ontario water levels are high and will to continue to rise. Easterly winds also direct waves onshore.  These have the potential to cause damage along the shoreline.

Residents are asked to stay away from the waterfront around Lake Ontario particularly parks and trails.

City staff have closed off access to Marina Park public boat launch, St. Lawrence Park and Jack Darling Park where the water has washed over some of the pathways, as well as the Lakeshore Road pedestrian underpass.

City staff, together with the Credit Valley Conservation Authority are actively monitoring the waterfront areas as well as weather conditions should further action be required.

The Environment Canada weather forecast calls for 15-65 mm of rain between Wednesday and Thursday. Thunderstorms and an additional 10-15 mm are possible in some areas. 

Residents are asked to please stay away from all waterways at this time as they can be dangerous, especially for children and pets.  

To report flooding, please call 3-1-1. For emergency assistance, please call 9-1-1. 

For safety and to reduce potential damage:

• Avoid walking or driving in flooded areas 

• Stay away from creeks, rivers and streams

• Keep children and pets away from all waterways

• Clear debris from catch basins near your home or business, as long as it is safe to do so 

• Call 3-1-1 to report blocked catch basins or road flooding in your neighbourhood 

• Do not open any sewer manholes under any circumstances

CITY OF Mississauga Continues to Advocate for Independence

Earlier this month more than 300 residents participated in the City of Mississauga’s Resident Town Hall meeting on regional governance. The meeting featured a detailed presentation by City Manager and Chief Administrative Officer, Janice Baker on Mississauga’s position for independence, followed by moderated questions and comments from both audience members and those watching the live stream.   

For more information about Mississauga’s position on the Regional Government Review, visit mississauga.ca/regional-government-review.

BACKGROUND

On March 27, Mississauga City Council adopted a motion, approving in principle that Mississauga become independent from the Region of Peel, subsequent to the Ministry of Municipal Affairs and Housing’s Regional Government Review

In January 2019, the Ministry of Municipal Affairs and Housing announced that it had appointed two special advisors, Ken Seiling and Michael Fenn, to review regional government in Ontario. 

The goal of the review is to help ensure these municipalities are working effectively and efficiently and can continue to provide the vital services that communities depend on.  The City will be submitting its official position for independence by the May 21, 2019 deadline, established by the Government of Ontario for public consultation. The outcome of the Regional Government Review is expected later this summer.  

The Ministry of Municipal Affairs and Housing is inviting online public consultation until May 21, 2019. Residents are encouraged to share their thoughts on regional government reform through this channel. 

Last week, at Regional Council, all four municipalities agreed to work together to have an independent financial analysis 

Proposed 2019 Development Charges Background Study Available for Public Comment

The City of Mississauga has released its proposed2019 Development Charges (DC) Background Study for the 60-day statutory public comment period.

The background study, prepared by Hemson Consulting Ltd, is a comprehensive report that includes input received from the public and development stakeholders and presents the proposed 2019 Development Charge rates to be included in the proposed 2019 Development Charges By-law.

The proposed 2019 Development Charges By-law will be available for public comment on April 18, 2019.

“The City charges fees to property developers to help pay for the infrastructure required to support growth, and these are called Development Charges or DC’s,” said Jeff Jackson, Director, Finance and Treasurer. “Without DC’s, the City would have to rely entirely on property taxes or other revenue sources to pay for new fire stations, expanding libraries and community centres and building overpasses and other infrastructure. The funds collected through DC’s ensure the infrastructure required to support growth is paid for primarily by growth.”

In addition to the proposed 2019 Development Charges Background Study, the City is looking for public input on two related studies: the proposed2019 Transportation Background Study prepared by WSP  and the 2019 Stormwater Management Background Study prepared by KSGS Engineering Corp. 

Comments on all three 2019 Development Chargesbackground studies, as well as the proposed 2019Development Charges By-law can be sent tosusan.cunningham@mississauga.ca.

Members of the public are also invited to attend Council on May 8 at 9 a.m. to speak to the draft background studies and 2019 DC By-law. To be placed on the agenda, please complete an online request or contact the City Clerk’s Office through our Citizen Contact Centre at 3-1-1 or 905-615-4311 if outside city limits.

The proposed DC background study and By-law will go to City Council for approval in June.

Spring Safety Message: Be Careful Around Waterways

Hazardous conditions on and around bodies of water

Credit Valley Conservation (CVC) is reminding residents of the dangers on and near local streams, rivers, ponds and lakes, particularly around this time of year. CVC urges people to exercise caution, and keep family members and pets away from the edges of all waterways as warmer spring weather approaches.

In spring we look forward to warmer weather and being outdoors. Warmer weather, however, usually brings rain, melting snow and shifting ice which can contribute to higher, faster flowing water in watercourses. Slippery, unstable streambanks and extremely cold water temperatures can also lead to very hazardous conditions close to any water body.

The Credit River Watershed has received a significant amount of snow this winter. A few recent thaws have helped decrease the existing snowpack. Melting snow due to warmer temperatures combined with spring rainfall and frozen ground conditions could contribute to higher water levels and increased water speeds in local watercourses.

There is still significant ice cover throughout the watershed. Several ice jams remain grounded along the Credit River at Barber (Paper) Mill Dam in Halton Hills, the Ferndale Park in Caledon and at Meadowvale Park in Mississauga. 

Remaining ice jams and ice cover on watercourses will weaken and become unstable with warmer temperatures. CVC continues to work with municipal emergency services to keep them constantly informed about current and changing conditions within local watercourses. 

CVC urges people to exercise caution and keep family members and pets away from the edges of all waterways and off frozen water bodies, which are extremely unsafe.

For more information, contact CVC at (905) 670-1615.
