4:58 PM: Seattle Fire crews are in the 5200 block of SW Canada Drive, just off Beach Drive, for a natural-gas leak. They’ve determined it’s “on the supply side of the line” – which is 1″ wide – and are evacuating some people nearby as a precaution. Avoid that stretch of Beach Drive (see the vicinity map) for a while. 5:43 PM: The last two SFD responders just left, and the call is closed.
