Decades before Superstorm Sandy, the Army Corps of Engineers came up with plans for hurricane walls in the Rockaways after a series of massive storms, WNYC reported. In the mid-1960s, after Hurricane Donna hit the Northeast, the Army Corps recommended building an 18-foot flood wall that spanned the beach (see above map). The plan could have saved the area from a painful cleanup after Sandy, but there was a lack of interest and funding for what would have cost around $100 million at the time, or $700 million adjusted for inflation. But now, with flooding recognized as a major danger, the plans have been dusted off and are being incorporated into new prevention brainstorming. Better late than never!
