There are currently three sirens located in the Florence area.
A fourth siren was purchased by Lane County and will be installed at Harbor Vista Park, which is in between the second and third sirens.
The Siren Tones
The sirens are at high-power capacity and have 2400 watts of power that cover up to a 4,000 ft radius. Optimum sound propagation conditions exist when there are no obstructions in the sound path, which means that wind speed and direction will be a prevailing factor in sound projection.
