In the distant past the City used to put 3 or 4 layers of brick along the gutters - now they put only one and not on all roads. I am told it is supposed to help the water flow better and have seen it in many places in Canada and UK. It does look good but I really wonder if it actually helps water floow.What about brick gutters next to the curb? Was that standard practice at some point? There are a few instances of that here and there.
