D.C. Is First to Plan to Remove, Retrofit Flood-Prone Buildings
– City sets goal for 2050 as threat from climate change worsens
– Challenges include new housing, addressing federal buildings
Washington is announcing a goal of retrofitting or removing all of its flood-prone buildings by 2050, the first major U.S. city to set such a policy. Washington’s proposal marks a new approach to that problem. The plan includes tougher building codes for new buildings, constructing new flood-resistant infrastructure and helping residents understand the climate risk they face. But retrofitting or moving the structures that already exist in flood plains may be the plan’s most aggressive proposal, measured by the cost and amount of change it could entail.
