Dispatching is a very imperfect activity filled with a ton of pitfalls...
That's why a CAD system should have common places in them, and dispatchers should be aware of potential conflicts. The person calling assumes we know everything down to the millimeter of their location. I can rarely get much better than a block radius on a cellphone call.
Thankfully, everything turned out ok, but still very unacceptable. We similar sorts of situations here. People in our county were not inventive when naming streets. So, we looking at our mapping program and clarify the town with the caller. Even worse, we have a street in another county across the Chesapeake Bay that has the exact same name and address range as one in our county. Thanks to lack of cell tower coverage we get calls for there about once a month.
The reality is this can happen anywhere, but can be prevented.
