    Why this exists

    In June 2021, storms put tens of thousands of metro Detroit basements underwater in a single weekend and brought a federal disaster declaration to Wayne County. Most homeowners had no idea their street had a history. The records existed the whole time. We are a southeast Michigan team that pulled them together so you can see your neighborhood's history before the next storm, not after.
