Issues that Cities Should Address


Recently, the Globe and Mail published an article on The Five Things All Canadian Cities Should Stop Ignoring. The article was straight to the point stating there are various issues that cities must address. It mentions affordable housing, reform to way in which cities deliver services, infrastructure and resiliency.

Cities need to plan for resiliency, in the past years we have seen how climate change has severely affected cities and how they function. From extreme flooding to extreme heat. Cities now have to think how to plan with these issues in mind.

Infrastructure is another issue cities need to focus on. Most of the infrastructure and development plans for Ontario are only short term solutions to long-term problems. Just masking these problems will continue to cost an enormous amount of money in the long-run. For example, the continual patch work of the Gardiner Expressway instead actually fixing the root of the problem. City officials need to sit down and consult with professionals on how to solve these issues.

Another point is, with the changing of municipal government, there needs to be a set “playlist” so that these plans for infrastructure and development are not changed or canceled and rebooted every other four years.

Finally, it is important to mention the “T Word”, taxes. Taxes are something that we have become to fear in North America. However, we tend to forget the importance of them. If there are no taxes in place, it is next impossible to solve these various issues, without cutting or reducing other important programs. We need to remind residents where the money from their taxes goes and the importance of it.

If cities are able to address this issues it may be possible to have much more sustainable and prosperous communities.

Storm Water Management and Mitigation

Over the past year or so, there has been the discussion around flood management in the GTA communities. Most of these discussions were a result of the heavy rainfalls and flooding that took place last July (2013).

One of the downfalls of early city planning was the lack of including the environment and natural design. If you examine some communities it is noticeable that there is a lot of imprevious surfaces (asphalt and concrete) and a lack of greenspace. Urban Flooding has a lot to do with imprevious surface.  I would recommend reading either Paving Paradise: The Peril of Imprevious Surfaces  or The Need to Redice Imprevious Cover to Prevent Flooding and Protect Water Quality. Both articles discuss the issues surrounding urban flooding and ways in which they can be mitigated.

If you were to go back almost 10 years ago to the Finch Avenue Flood that washed away some of the roadway. It was partially due to both altering the natural flow of water for development and the massive amount of asphalt and cement in the area. The large amount of imprevious surfaces resulted in the water not having any place to go and building up.

Some communities are now focusing on and removing their imprevious surfaces and replacing them with either pemerable paving or creating gardens. An example of pemerable surfaces/paving that is currently being used for both commercial and residential uses is a company called CoreGravel. CoreGravel uses a series of raised hollow hexagons which can be filled with either gravel, soil, or grass. What I like about this product is that even though it is pemerable surface and can be filled with various product, it is still strong enough to stand up to the weight of automobiles and accessible  devices.

A lot of communities are now focusing on rain gardens. These are gardens that are usually incorporated beside the sidewalk, where water run-off can be catched and reduce flooding. Take a look at these examples in various North American communities.

I would suggest that GTA communities begin focusing on adding and increasing their pemerable surfaces to help reduce urban flooding. There should also be a focus on ‘wild design’ and incorporating nature into current and future designs. It would also benefit communities to add in more greenspace such as Greenroofs and rain basins to reduce runoff. Implementing this now, would be able to reduce the cost of flooding and water damage in future years to come.
