## 2008 tornado and flood

New Hartford was struck by a confirmed EF5 tornado on May 25, 2008. Two people were killed as well as seven people in nearby Parkersburg. This is the second confirmed EF5 tornado since the Enhanced Fujita scale was introduced, the other occurring in Greensburg, Kansas, on May 4, 2007. The town was prone to flooding until a levee was built around the town, which was raised and reinforced in 2009. In June 2008, only one week after being struck by a record EF5 tornado, the town experienced record flooding that forced all residents to evacuate. The flood damaged many homes and buildings in the town then incited relief efforts from FEMA and the American Red Cross. The Red Cross provided food assistance in the town, distributing grocery items at the town's community building and fire station, as well as providing meals out of a food truck. Some affected residents temporarily lived in FEMA trailers. Many residents made efforts to repair their homes, while others relocated outside of the town.
