I went to an onsen (hot spring) town in Japan. They have hot spring water, so on a lot of the streets business owners just turn the hose on and point it downhill. Worked pretty well for keeping the streets clear of snow, but requires a lot of existing geographical conditions.

Doesn’t that make the roads slippery? And if there’s a real cold wave, it all might flash-freeze regardless.
less slippery than snow/ice. but to flash freeze hot spring water, that is maybe 50°C or hotter, it must be really really really cold.
