    How Can the Department of the Air Force Prepare for Natural Hazards?

    Some Air Force facilities are exposed to flooding, high winds, wildfires, or even multiple hazards. Future costs of damages are uncertain, and climate change could affect the frequency and scale of these hazards. The process for making investment decisions regarding resilience should be flexible.

    Green Infrastructure Can Help Manage Rainfall in an Urban Watershed

    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.

    Future of Coastal Flooding

    President Obama's executive order that directs federal agencies to plan and build for higher flood levels as they construct new projects in flood-prone regions will affect hundreds of billions of dollars of future public works projects. In an ideal world, planners would estimate the benefits and costs for each project, taking into account everything from the details of the local landscape to the potential for adaptive responses over time.

    How RAND Supported the Development of Louisiana's Comprehensive Master Plan

    To plan the rebuilding of the Louisiana coastline, the Coastal Protection and Restoration Authority used a new analytic approach, developed in part by RAND, that incorporates results from state-of-the-art predictive models within a decision tool to formulate and compare alternatives and visualize outcomes and trade-offs for policymakers and stakeholders.

    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.
