Hey everybody!
I have been working on this on and off, and it still isn't quite complete (obviously), but I still believe it deserves a share.
I've been out in central Iowa on and off for about two years while at college, and have seen my fair share of sirens, but there are very few maps from this area that are either up to date or accurate...that's where I step in! I have all of Story and Polk counties completed, but there are still many, many sirens to find and update for other counties.
Locations gathered from Aaron's (given to me by Michael), Donald's, and Max's siren maps, with many locations added/updated. Thanks, guys!
Sirens can be sorted by the following colors:
Red: ACA
Orange: American Signal
Yellow: Whelen
Green: Sentry/Sterling
Teal: Darley
Blue: Federal Signal
Lighter shades: omnidirectional
darker shade: rotational
White star: inactive/abandoned
Red X: removed
