Other: Workers grinding the sidewalk are generating significant clouds of silica dust. Silica-generating grinding operations are supposed to be controlled by water or vacuum. The vacuum systems they are using are clearly ineffective. This is clear if you watch them work, it's also clear if you examine a recently ground section of sidewalk. Significant concrete dust remains on the sidewalk surface because the vacuum isn't picking it up. The city is substituting a respiratory hazard for a trip hazard. I don't want to get these guys in trouble, but would appreciate if the city would ensure they're using water or effective vacuum controls.
