Montreal's sponge parks, designed in a way to deviate as much rain water as possible away from the sewers, have saved a bunch of areas from flooding due to Beryl's rainfall.
So you get really nice parks in a major city, with a bonus against flooding.
They're making more of them now and I love it
If you like the sponge parks, you’ll love the sponge sidewalks - we have so many in our neighborhood, advertised as traffic calming measures when they first started installing them. They really dropped the ball promoting them that way as the auto-philiacs got all frothy about that.
