    Civilians and Military Collaborate to Address Climate Change

    May 13, 2020

    The Hampton Roads area in Virginia is home to more than 1.7 million people, a major port, and more military installations than anywhere else in the United States. Its rising sea levels and floods brought together civilian and military officials on a project to mitigate damage and foster resiliency.

    Green Infrastructure Can Help Manage Rainfall in an Urban Watershed

    Oct 29, 2020

    Urbanization, inadequate investment in aging infrastructure, and more-frequent heavy rainfall events due to climate change have led to sewer overflows, flooding, and reduced water quality in U.S. cities. The challenges of increasing volumes of stormwater can be addressed by a mix of solutions.

    Tools Can Help Policymakers Increase Coastal Resilience to Rising Seas and Storm Surge

    Two key analytic tools can be used to evaluate how coastal protection and restoration decisions made now will play out over time, even given an uncertain future. For example, a community weighing whether to implement a marsh-building project can see how the project fares against different rates of rising sea levels over time.

    A Year After Sandy, a New Threat to New York City

    As residents continue to recover from Superstorm Sandy, they are about to confront dramatic changes in the flood insurance landscape. Changes to federal floodplain maps will mean thousands of New Yorkers will suddenly be living in areas designated as high-risk flood, which will send their insurance rates soaring.

    Rising Cost of Flood Insurance Will Create Serious Challenges for New York City

    Some New York City residents may soon face sharp increases in their flood insurance premiums as a result of major changes occurring in the National Flood Insurance Program and the redrawing of flood maps that expand the areas at risk. Property owners in areas now deemed at highest risk may face increases of $5,000 to $10,000 annually.
