A nonprofit research group, the Urban Land Institute (ULI), recently released a report which outlines Boston's options for dealing with rising waters. The sea level in Boston is currently rising at a rate of 0.11 inches per year. That may not seem like much, but eventually it could cause major, costly problems for the coastal city -- especially in the event of large storms like Hurricane Sandy. ULI offers numerous suggestions, including constructing artificial reefs, marinas, and algae farms; reconfiguring utility and drainage systems in low lying areas to accommodate floodwaters; and building seawalls and dunes. The fifty-two page report lays out potential plans of action in four different areas of the Boston area: the Alewife Quadrangle, The Innovation District in South Boston, Back Bay, and Revere Beach.
