  • Land disturbance greater than or equal to 4,000 square feet;
  • Excavation or fill greater than or equal to 400 cubic yards;
  • Public or private driveway and road construction or reconstruction longer than 125 linear feet;

  • The construction or reconstruction of a continuous distance of 100 linear feet of road ditch, non-agricultural grass waterway, or other non-agricultural open channels

Stormwater permits include erosion control practices during construction and post construction stormwater management for commercial, industrial, or platted subdivision development that increases impervious surface by more than 15,000 square feet.
