Did the City Salt the Sidewalks?

“Dear PoPville,

I was walking down New Hampshire Ave in Petworth this morning to go to the metro, and noticed that all the sidewalks were salted with the same ice melt. I noticed at first because my sidewalk was salted, and I didn’t salt it (but yes, I did clear it of snow with a shovel), and the salt extended to the stairs up to my house. Later down the street, I noticed that the salt also reached peoples’ front yards in the grass. Does DC go around with a truck and salt some sidewalks? I had never seen/noticed this before.”
