From WNYC:

City Council Speaker Christine Quinn laid out a massive $20 billion proposal Tuesday to combat the effects of climate change on New York City’s infrastructure as the region continues to assess damage and plan clean-up after Hurricane Sandy…

The plan was framed around two key issues: how to prevent flooding and how to safeguard infrastructure. It includes studies to assess what solutions – from manmade sea walls to natural defenses like sand dunes – could best protect the city’s most vulnerable neighborhoods.
