update for the map:
Pleasant hill had a 2T22 in Magellan pipeline near the 10V2T, and 3T22B at sunrise park, and a STL-10 at doanes park.
The STL-10 & 3T22B were removed in 2013/2012, while the 2T22 near Magellan pipeline was removed in 2018/2019.
Another note is that the STL-10 used to be a noon whistle siren before switched to monthly testing
