The Toronto and Region Conservation Authority will be presenting their “preferred solution” to flooding in the Rockcliffe–Smythe area on March 1. The presentation will be online.
The TRCA’s environmental assessment started last year ” to determine a preferred riverine flood mitigation strategy for the Rockcliffe-Smythe neighbourhood”, which is “the most flood vulnerable area in TRCA’s jurisdiction”. It addresses only ‘riverine’ flooding—not sanitary or storm sewer floods.
The presentation materials for March 1 suggest that the TRCA will not recommend naturalizing the Black Creek channel, because it would have a large deleterious impact on the local area, including Smythe Park.
Instead, the TRCA recommends widening and deepening the channel, with some other design changes to bridges and alignments.
A piece of good news has emerged from the life that was going on before COVID 19 hit.
As a reminder, in 2018, St Helen’s Meat Packers somehow managed to buy an 8-acre parcel of contaminated flood-plain land from the city after the Toronto and Region Conservation Authority, normally fiercely protective of flood plain land, gave permission for its sale and use as a meat packing plant.
The site borders Rockcliffe Boulevard, a street where homes are flooded in severe rain events. The last hope for residents to stop the plant’s construction is a judicial review in which a judge will check to see if all protocols have been followed. Reviews are expensive but the $25,000 cost has been raised through a combination of public fundraising and private donors. Landscape architect Devin Tepleski organized the successful fundraiser. Incidentally, and in keeping with the councillor’s style of appearing to support both sides; one of the donors to the fundraiser was none other than Frances Nunziata.
The Humber river is breaking its banks in several places this morning after a record rainfall for the 11th January. The previous highest rainfall, 22.6 mm fell in 1960. Yesterday’s rainfall for the day was 59.0 mm which for those who still think imperially is 2.3 inches. Unusually for January all the day’s precipitation was rainfall. Because the ground was frozen and unable to absorb the water, it was drained into the Humber, causing the current high levels. Incidentally, the water was still rising at 11:30 this morning. Let’s hope none of our readers were affected negatively by this rain.
Here are a few shots taken along the Humber this morning. I couldn’t venture far into Cruickshank Park as the path was completely flooded. As always, click to enlarge the images.
The power of the current is evident from this shot just north of the Lawrence Avenue bridge.
Update: Hans Havermann sent a link to his blog showing the high water in Raymore Park.
Just 8 days after NDP leader Jagmeet Singh visited residents of Rockcliffe-Smythe, another heavy rainfall inundated the area and a nasty sewage mix flooded many homes. It must be the last straw for families who were flooded as recently as last year. Last week, resident Franco Ruffolo despaired that his house is uninsurable and unsellable because of the regular flooding. Franco, and many others in Toronto and particularly in Ward 5, York South-Weston, constantly dread that heavy rain will lead to the inundation of their homes.
The problem stems from the fact that as more of the city becomes paved over, runoff from roofs, driveways and streets is dumped directly into channels, rivers and storm sewers which in many parts of the city are combined with the sanitary sewers. This means that rainfall overloads the combined sewers leading to raw sewage being dumped into rivers and eventually into homes – City News.
In the Rockcliffe-Smythe area, the creek that used to flow naturally through the area (Black Creek) was channelled into a concrete straight jacket. Thanks to heavier rains and more buildings, the channel overflows occasionally with horrible yet predictable results. In other areas, the extra pressure on a combined sewer forces sewage up into homes through basement drains.
What can be done? We need to plant more trees, put up green roofs, divert downspouts so that runoff from roofs drains onto ground where it will be absorbed rather than piped directly into sewers. We also need to separate storm and sanitary sewers so that raw sewage stays out of people’s homes and our rivers and creeks. A few years ago, Toronto instituted a mandatory program to disconnect downspouts where possible. Most of all, we need politicians and agencies to actually do their job and work for the people.
Councillor Nunziata in the City News clip blames the TRCA for dragging its feet. The horrible flooding of six years ago should have propelled all actors in this tragedy to get their act together and do something. Sadly, the councillor even voted against an innovative hard surface charge that would have made homeowners pay for the hard surfaces covering their property. This revenue would have been directed towards flood relief but Giorgio Mammoliti framed it as a roof tax and Council (including Mayor Tory and Ms Nunziata) voted against it.
Perhaps it’s time for politicians and agencies to stop the blame game and actually do something. We can start by accelerating the separation of storm and sanitary sewers in priority areas. Holding tanks can reduce the flow in the meantime and planting trees would help. We also need Council to take this issue seriously.
No matter what you’ve been told, strictly speaking, hurricanes don’t happen in Ontario. The fuel that keeps them going is warm ocean water and once landfall is made, they soon become extra-tropical storms and usually fizzle out with a bit of wind and rain – that is if they can actually make it all the way up here. Why then, sixty years later do we talk about Hurricane Hazel and its devastating effects on our neighbourhood?
Early in October 1954, a group of clouds that had formed off the coast of Africa began rotating and became a tropical storm. In the days before satellite monitoring of weather systems, there was a great deal less certainty about the path and nature of hurricanes during the June to November storm season. Back then, tropical storms and hurricanes were only detected once they came close to a populated area. This particular tropical storm was spotted in the Caribbean and being the eighth of that year, was by convention, given a girl’s name beginning with H; Hazel. She quickly strengthened into a powerful hurricane and sweeping through Haiti, Hazel took the lives of several hundred people. Then, dragged north-west by an upper level low pressure area sitting in the Mississippi Valley, Hazel made landfall in North Carolina on October 14th as a category 4 (out of 5) hurricane. Hazel was then expected to fizzle out and become a rain event but picked up energy from the low pressure area and set its sights on Ontario.
Again, before satellite tracking and computer projections, weather forecasting was something of an art. Although there was some warning about the approaching storm, Ontarians were unprepared for what was to come. Ominously, there had been considerable rainfall in the previous two weeks leaving the ground saturated.
On its way to Ontario, Hazel was re-classified as an extra-tropical storm. Even though its winds had weakened, it still carried a vast amount of water. Once over Brampton, Hazel combined forces with the Mississippi Valley system forming a new storm that stalled and unloaded its rain onto the already saturated ground. As night fell, the rain continued, putting pressure on the two major watersheds in the region, the Don and the Humber. It is estimated that a volume of water the size of Lake Simcoe fell on the Humber River watershed alone – and only one escape route – the Humber River valley.
As the evening progressed, flash flooding inundated low-lying homes along the Humber. Occasional ice-jams had caused flooding in the past but this was different. The water’s rise was rapid and relentless. By the time people realized that their lives were in danger, it was too late. In Weston, five people perished. On Raymore Drive, just across the river from Weston, a suspension footbridge blocked and diverted a torrent of water into the lower homes on that street and 35 people lost their lives. In one instance, in response to the rising water, a family moved possessions from one house to another only to lose their lives when both homes were inundated. A nearly complete list of fatalities is here.
In the aftermath of Hazel, the forerunner of the Toronto and Region Conservation Authority was formed and given the power to clear floodplain homes creating Toronto’s famous park and ravine system. Today, along with many Toronto communities, Weston is blessed with beautiful parkland and sports facilities along the Humber. Raymore Drive now ends at Tilden Crescent but the depressions of the former homes’ basements are still faintly visible in Raymore Park. Native trees and other rain absorbing vegetation are being planted and plans are afoot to remove concrete channels and replace them with natural riverbeds. Even though there is more paving today than in 1954, the disconnecting of downspouts from sewer systems, floodwater holding tanks and the encouragement of green roofs and driveways are techniques that will allow water to be absorbed into the ground rather than quickly drained into the river.
Most days, as in the past, the Humber flows gently through our parks and ravines. Even though 60 years have passed and measures have been taken to remove people from the path of danger, occasionally, as on July 8, 2013, we are reminded that no matter how well prepared we are, nature often has the last word.
