A major levee breach affects much more than homes. It affects businesses, government buildings, infrastructure and communication. It affects offices, hospitals, grocery stores, schools and places of worship.

This map is created by disaster geographer Ezra Boyd utilizing data obtained by Levees.org from FEMA 2009 in a request under the Freedom of Information Act (FOIA).

The New Orleans Ladder recently commissioned disaster geographer Ezra Boyd to create an interactive map using this levee data.  By clicking here, you can access this free interactive map which provides details about levees in every state.

  1. You know this information makes the case for more chapters of Levees.org in more states.

    As Ezra and I work to develop the interactive features, hopefully these other chapters will be able to input their own local levee data and information onto the Levees Interactive Map.
    In line with your own focus, per the Atlantic interview, we hope to make this Map: Open Access, though it will be more tightly administrated (by me) than Wikimedia or Wikipedia. (for example: Editilla eats Corps Astroturfers for breakfast so don’t even try it 😉
    I hung it on the masthead of my blog http://noladder.blogspot.com/

    Thanks again for making this Map possible in the 1st place, Sandy, and I hope others take Ezra and my example to BUMP IT UP A NOTCH, or jump in however, like start their own levees.org in their own state to hang with us.
    To mangle Ben Franklin: “We either hang together or we will surely all drown separately!”

    The Levees Interactive Map will help us chart our way together to all the places we are winning.

    We are currently interviewing a potential chapter director for Arizona which has three cities with population greater than 300,000. Mesa, Phoenix and Tucson.
