Pervious or Impervious? (Are you)

I don't know if the pavement is permeable (almost anywhere else I'd wager no), but I do know the green roof is, and every time lately I'm in the Bronx and at this site, it seems it pours. (I knew that impervious was a word, but I didn't know that pervious was. Huh.)
