Neighborhood? How about half a city?
When we were decommissioning the old Fabian Avenue telco Central Office (now home to the Charleston Village condominiums), I was given the task of making sure the electrical power to the site was off. Not just at the breaker down in the street box, but the physical breaker at the Colorado Avenue Sub Station in Palo Alto was to be pulled, thus making certain all power was deactivated until we could make certain everything was isolated.
This would involve taking out the entire Charleston Gardens section of Palo Alto for an hour or so mid-morning, mid-week when it would cause as little disruption as possible. (Charleston Gardens is a mostly residential section of Palo Alto, bordered by Middlefield, San Antonio and Charleston roads, if you care.) The neighbors were notified the week before, both by snail-mail and people physically knocking on doors to explain and hand out the small paper notice explaining what and why.
Come the morning of the Great Event, I was selected to physically make sure the power was off at the sub-station. Cell phones being a fad of the future, I drove down the Frontage road (West Bayshore) and arrived at the the sub station promptly at 10AM. Conversation went something like this:
Me: I'm here to see that the power to the Fabian project is off.
Site Engineer: We're all ready for you, I'll get to it in a second ... or you can just throw that switch (points).
Me: OK (throws switch).
Engineer: NOT THAT SWITCH!
Most of South Palo Alto: WTF‽‽‽‽‽
Management swallowed the story that the main breaker tripping was an un-foreseen knock-on effect of the smaller section being taken down ... The Engineer and I made a bee-line for Fred's as soon as he cleared up the problem, which took into the late afternoon. We're still friends.
