Flood Warning Sirens

Fredville operates four flood warning sirens, each placed in a part of the city that lies within the 100-year floodplain.

Flooding can happen in these areas, and getting in or out of them may become impossible during a flood emergency.

When a flood siren goes off, you will hear four tones and then a spoken message announcing an emergency, warning that water is rising and telling you to leave the area.

Siren Locations

Each siren covers color-coded zones, and what you should do depends on the zone you are in when it sounds.

Siren 1: Copperleaf Drive

  • Red zone: evacuate the area
  • Purple zone: shelter in place
  • Green zone: no action needed

Siren 2: 1140 S. Kestrel Line Road

This siren has red and green zones only.

  • Red zone: evacuate the area
  • Green zone: no action needed

Siren 3: 315 Redbud Drive

Follow the instructions for the zone you are in.

Siren 4: Heron Creek at Wrenfield Parkway

This siren has red and green zones only.

  • Red zone: evacuate the area
  • Green zone: no action needed

Testing

The flood sirens are tested on the first Wednesday of every month, weather permitting, right after the city's regular 1 p.m. test of its outdoor warning sirens. A test sounds two tones followed by a spoken message saying that it is only a test.
