The history of flooding along the 400-mile Connecticut River runs deep, and disaster management expert Josh Shanley says one flood should be instructive.

In his new book, Connecticut River Valley Flood of 1936, Shanley examines that devastating event, and warns that “past is prologue," calling for "a coordinated effort by many agencies on all fronts" to prepare for future flooding.

According to the American Society of Civil Engineers, there are 284 high-hazard dams in Connecticut, and 21 miles of levees that protect $3.4 billion in property. Much of this infrastructure was installed nearly 90 years ago in the wake of the 1936 flood, Shanley explains, and "needs to be maintained, and in many cases upgraded."

Shanley is "concerned," noting that these systems were built to withstand "certain climate patterns, certain precipitation patterns." He says "the big question is whether they... even on a good day would have survived the different changing precipitation patterns and in-between droughts that we're anticipating."

Plus, we hear about the nature-based flood resiliency plans being discussed in the coastal City of Groton. Economic Development Specialist Cierra Patrick gives an update on the city's Community Resilience Plan. For some low-lying neighborhoods, flooding could mean an existential threat.
