The Davis Square Community

"The “blue barrels” contain a sand-salt mix that is made available to motorists for use on roadways when needed to help with traction in icy conditions – especially on hills. As a practical matter, some residents use the mixture on their sidewalks after shoveling, but they’re not supposed to use the mix on private property for their walkways and steps. (The salt, by the way, is corrosive to brickwork and concrete, which should discourage people from using the mixture on private property.)"
