^ That's cold 'O, very cold.

Wait until the temps are -15 or colder.

Rough walking conditions out - especially in this park this morning.
Sand was applied, but not sufficient. Ice is thick. Very poor condition.

^ They should have had heated paths (temp. and humidity sensor controlled) -- best, least costly, most efficient means of snow and ice removal.

Are heated paths really cheaper than typical snow removal + gravel?

Salt is toxic to plants, so probably not going to use that on the paths. The pebbled texture probably helps a bit but that freezing rain did no services, it's bad everywhere.

Yes they are. Of course the upfront installation cost is a Capital Cost; and maintenance vis a vis snow and ice removal is an Operational Cost. For Edmonton the pay-back would be slightly less than 10 years (OpEx to cover CapEx). These systems have been and are regularly/newly applied in Iceland, Norway, Denmark, Sweden and Finland. The heat, controlled by sensors, is only applied when both temperature and humidity combine to create a predictable snowfall (or freezing rain) and only through the duration of the event -- max 70 times per year for an average duration of 3.5 hours (math then = heat for 245 hours per year or 10+ snow days).
The alternative requires application of sand and (on footpaths) salt and when the accumulation is substantial actual removal to a remote "collector" location. If you compare the energy of the two systems (as I have done for the University of Alberta) the heat energy is less than 1/2 of the energy involved in conventional snow removal systems.
The disappointing part is that CoE hardly ever considers OpEx and is always focused on CapEx.
Incidentally this also has an impact on slip-and-fall human injury which can be a substantial cost to the City as well.

Thanks for the response, I had no idea.

A great example of what happens to all MUPS thanks to the stupidity of 3 day clearing on most of them, even high traffic, centrally located ones. Hence why then need to be 24hrs. So hard to fix once this happens and will literally need to spend more money to try to remedy…or just leave as unusable for days on end…

The city really ought to rethink their "apply a shit ton of gravel/sand" strategy for freeze-thaw and actually clear the ice when it gets like this. This just creates a mess when it melts and it's pretty much unusable to many people on foot.

Heated Path in a mountainous area of SoCal (rendering) -- it would be a great solution for MUPs in Edmonton

I walked through the park on my way home from work and a "shit ton of more sand" was added compared to this morning. Better traction now for sure but as noted, it will get messy.
