I bring this up because I feel that this has an application to Montreal. Montreal receives a fair amount of snow in the winter, snow which makes walking on sidewalks difficult. By raising a sidewalk and providing a drain, the snow accumulation on sidewalks will be lessened. Furthermore, the use of an arcaded sidewalk similar to the one above will shelter the sidewalk and reduce the snow accumulation even further.
Food for thought in designing street-side buildings....
