Outdoor Storm Sirens

 On June 25, 2014, the City of Geneseo updated storm siren locations within the city limits; adding a new siren and relocating an existing siren.  A new siren has been added to the water stand pipe located at the SW corner of Chicago and U.S. Highway 6. The siren previously located at Boelen Field has been relocated to the former civil defense building north on Illinois Route 82. Braniff Communications assisted the city with the relocations, coverage mapping and purchase of the sirens. The upgrades will better alert outdoor areas in the event of severe weather. The siren locations also add redundancy in case of a siren failure. The sirens are tested at 10:00 a.m. on the first Tuesday of each month.
