Estimated Siren Coverage Map

I made this coverage map of the city of Watertown's new 2001 130 AC/DC siren system that replaced an aging and outdated EOWS-612 system.

Facts:
The firs sirens to be installed were around Lake Kampeska in 2014
The Second Set was installed in 2015 MOST of them are in original 612 locations even though Federal provided a recommended placement map
During the bidding process 2 major vendors sent in proposals, Federal Signal and American Signal, naturally Federal Signal won cause they met the city's requirements.
Another bid went out for installers only an in town electric installer won that bid.
The old 612's were located at a city shop and a city out west bought them, when they arrived to pick them up, they opened the horns up and removed the speaker drivers, on the controls they removed the control components and left the city with empty shells of the 612s.
The old system was for a summer switched to Alert tone and the voice messages deactivated so when 12:00 PM rolled in the sirens sounded Alert
They decided to test the 2001 130's 3 main signals during light rain storms without informing the public to see how they would react, this happened in a 3 day span and they found people reacted to Alert better then wail or fast wail to made it permanent to use Alert.
