On March 18, 2008, ground water levels rose to a 30-year high in the Bellevue, Ohio, area. Surface and near-surface geologic conditions combined with unusually high precipitation caused extensive flooding of fields, roadways, and residences. Existing basins and sinkholes, caverns, and underground drainage (collectively called karst) exacerbated the flooding and the area drained slowly over the course of months.
Map EG-5 describes the flood area and background geology, including karst features and terrains; reviews the nature of the flooding; and provides map documentation of the flooded area for future land-use planning by citizens and government. The 1:24,000-scale, wall-size map is printed on high-quality paper and shipped in a mailing tube for $18.50 (plus sales tax and shipping).
