Floodplain Management

Jack’s Defeat Creek and its tributaries periodically overflow their banks causing damage to those properties in and near the floodplain. 

In recent years, these floods have increased in frequency, in part due to increased runoff from new development, and also from the accumulation of sediment washed through storm sewers into waterways. The Town’s stormwater utility is managed by the Ellettsville Public Works Department and is responsible for maintenance to the Town’s stormwater infrastructure.

The Department of Planning is responsible for ensuring that any development that occurs within a floodplain is done in accordance with floodplain regulations. Any development that occurs within a floodplain requires a floodplain development permit. Types of activities that are considered development are:

  • New construction
  • Additions
  • Remodels
  • Accessory structures
  • Grading
  • Paving
  • Right-of-way improvements

Additionally, any development that occurs within the regulatory floodway also requires a Construction in a Floodway permit from the Department of Natural Resources.
