Should Widett Circle Be Used To Protect Boston From Floods?

After last week's powerful storm surge caused severe flooding along parts of the coast, Boston Mayor Marty Walsh made a point of addressing climate change at a press conference on Thursday.

"If anyone wants to question global warming, just see where the flood zones are -- those zones didn't flood 30 years ago, some of those areas," he said.

And he added, it's going to mean future projects take climate change into consideration.

But Bob Zimmerman, executive director of the Charles River Watershed Association has a different idea — why develop some areas at all? Why not instead, let the land act as a natural flood control?
