Alternative Sidewalk in White Rock

I ran across a SEA (street edge alternative) street in White Rock today, but on taking a closer look, it appeared to be more of an alternative sidewalk. SEA streets do away with curbs and gutters, and replace them with vegetated swales to reduce the impact of rain into storm drain systems and filter out pollution. This street had small swales but it still had a curb... Hmm... There were openings cut into the curb here and there, with small guides to let street runoff in, but I don't think they would accomplish much.

As you can see, the regular storm drain is still in place, and the teeny street diversion would not move much water into the swale.

I'm not an engineer, and I'm scratching my head on this one :-). Most such projects attempt to capture the polluted water from streets... Not nearly as much pollution on the sidewalks...
